MULTICAL® 602
TECHNICAL DESCRIPTION
1 General description
MULTICAL® 602 is a thermal energy meter with many applications. In addition to being a precise and reliable heat
meter for battery or mains operation, MULTICAL® 602 is also used for:
• Cooling measurement in water-based systems
• Bifunctional heat/cooling measurements in separate registers
• Leak surveillance of hot and cold-water installations
• Power and flow limiter with valve control
• Data logger
• Data communication
• Energy measurement in open systems
In designing the MULTICAL® 602 we have attached great importance to flexibility via programmable functions and
plug-in modules (see chapter 10) in both the calculator top as well as in the base unit to ensure optimal use in a
large number of applications. In addition, the construction ensures that already installed MULTICAL® 602 meters
can be updated via the PC program METERTOOL.
This technical description is prepared to give utility managers, meter electricians, consulting engineers and
distributors the possibility of utilizing all functions available in the MULTICAL® 602. Furthermore, the description
is made for laboratories for the testing and verification process.

MULTICAL® 602
TECHNICAL DESCRIPTION
3.3 PROG, A-B-CCC-CCC
The legal parameters of the meter are determined by Prog, which can only be changed when the verification seal
is broken. The change must then be made at an accreditated meter laboratory.
The A-code indicates whether the flow sensor (V1) is installed in flow or return pipe. As water has a larger volume
at higher temperatures, the calculator must be adjusted for the current installation type. Wrong programming or
installation results in measuring errors. For further details on placing the flow and return pipe of the flow sensor in
connection with heat and cooling meters, see paragraph 5.1.
The B-code indicates the measuring unit used for the energy register. GJ, kWh or MWh are used most frequently,
whereas Gcal is only used in some countries outside the EEA.
The CCC code indicates the calculator’s adaptation to a concrete flow sensor type, i.e. the calculation speed and
display resolution are optimised to the selected flow sensor type and at the same time the type approval
regulations concerning min. resolution and max. register overflow are met. The CCC codes are divided into several
tables to give a better survey.
CCC(V1) indicates the CCC code of the flow sensor and is connected to flow sensor input V1 on terminal 9-10-11
(or 10B-11B), which in most applications is the flow sensor used for calculating energy.
CCC(V2) indicates the CCC code of an extra flow sensor, if any, to be connected to terminal 9-69-11 (or 69B-79B).
If V2 is not used, CCC(V2) = CCC(V1). In connection with leakage surveillance CCC(V2) = CCC(V1).

The CCC tables are divided into fast pulse codes (CCC=4XX, 2XX and 1XX) for electronic meters, e.g. ULTRAFLOW®,
and slow codes for e.g. reed contacts (CCC=0XX).
Electronic meters with fast and bounce-free pulses as well as info codes for ULTRAFLOW® X4
CCC= 4XX
Max. pulse frequency: 128 Hz
Max. integration frequency: 1 Hz
CCC= 1XX, 2XX
Electronic meters with fast and bounce-free pulses
Max. pulse frequency: 128 Hz
Max. integration frequency: 1 Hz
CCC= 0XX
Mechanical meters delivering slow pulses with bounce (flow sensor type "L")
Max. pulse frequency: 1 Hz
Max. integration frequency: 1 Hz
Max. integration frequency is 1 Hz for all types. The CCC codes are arranged in a way that qs+20% (or
Qmax+20%) does not exceed the 1 Hz in the integration frequency.
Example: CCC=107 (applies for a qp 1.5 m3/h meter) : 1 Hz in the integration frequency is obtained at
q = 3.6 m3/h.
EN 1434 makes demands on the resolution and registre size of the energy reading. MULTICAL® 602 meets these
demands when connected to below flow sensor sizes:

Current flow (l/h or m³/h) reading is calculated on the basis of the measured period between 2 volume pulses
(see paragraph 6.5)
When one of above CCC codes has been selected both CCC (V1) and CCC (V2) must be selected from this table.
Note: Continuous maximum water flow and permanent ΔΘ > 75 K may cause overflow in the daily data logger at
CCC=010-011-012-013-150-202-205. With these combinations we recommend you to use Prog. data logger type
67-0B or type 67-00-22.

DDD=210 is the ”standard code” for heat meters with meter type 602xxxxxxx2xx. Please contact Kamstrup for
other combinations. Max. number of readings of a DDD code is 110. Of these, reading of data logger counts for 4
readings. Top module no. and base module no. to be left out of account.
A complete survey of existing display codes (DDD) appears from a separate document.
Please contact Kamstrup for further details.
Note: Data reading can retrieve up to 36 monthly data and up to 15 yearly data. Number of yearly and monthly
data to be shown in the display is determined by the DDD code in each case.

The heat energy E1 is always counted in the main register. When the power exceeds the limit set for TL2, i.e. 20
kW, but is below the limit set for TL3, i.e. 30 kW, the heat energy E1 is counted in TA2, but only as long as TL2
exceeds 20 kW and is lower than 30 kW. It functions as a contact T2, which closes the moment TL2 surpasses 20
kW. As soon as the power either surpasses 30 kW or falls below 20 kW, the contact breaks again and counting
stops in the TA-register. If the power surpasses 30 kW the contact T3 closes and now all the energy E1, which is
consumed as long as the power remains above 30 kW is counted in T3. This energy E1 is counted in both the
main register and in TA3.
•
Please note that only tariff No. 20 can be used in a combined heat / cooling meter. All other tariffs may
only be used for either a heat meter or a cooling meter. The meter can not distinguish heat energy (E1)
from cooling energy (E3) and vice versa.

NB: M=2 and N=2 are default values when leakage surveillance is used. Higher degree of sensitivity, e.g. M=4
can only be obtained by means of METERTOOL.
Info codes for leakage/bursting (info 256/512) are only active when M > 0 or N > 0.
3.8.1
Example of District Heat Leakage level (Leak level)
In this example M=2. Having a qp=0.6 m3/h flowmeter, qp must be converted to l/h: qp=600 l/h.
If we assume that there has been a means flow of 50 l/h then there will be counted approximately 1200 l/day.
10% of this value is 120 l/day. Further, 1% of qp=600 l/h is 6 l/h equivalent to 24 x 6 l/h = 144 l/day. Leak level
in this case will be 120 + 144 = 264 l/day or equivalent of 6 l/h.
3.9 >T< Configuration of encryption level
MULTICAL® 602 is available without or with encryption of the data transmission. If encryption of data is selected,
128 bit AES counter mode encryption is applied. The encryption level cannot be changed after production.

The meter can only be read if the reading system recognizes the individual meter’s encryption key.
The encryption key is forwarded to the customer and ”matched” with the individual meter’s serial number in the
reading system.
If the encryption key is lost, the meter cannot be read. A new encryption key must be supplied by Kamstrup.
Only encrypted data via the base modules can be read by Wireless M-Bus.

MULTICAL® 602
TECHNICAL DESCRIPTION
5.2 EMC conditions
MULTICAL® 602 is designed and CE marked in accordance with EN 1434 Class A and Class C
(corresponding to Electromagnetic environment: Class E1 and E2 in the Measuring Instruments Directive)
and can therefore be installed in domestic and industrial environments.
All control cables must be installed separately and not in parallel with e.g. power cables or other cables
with the risk of induction of electromagnetic interferences. Control cables are laid at a min. distance of 25
cm from other installations.
5.3 Climatic conditions
MULTICAL® 602 is designed for indoor installation in noncondensing environments with ambient
temperatures from 5…55°C, however, max. 30°C for optimal battery lifetime.
Protection class IP54 allows periodic splashes of water, but the apparatus cannot stand constant moisture
and flooding.

5512-931 GB/09.2011/Rev. B1
MULTICAL® 602
TECHNICAL DESCRIPTION
6 Calculator functions
6.1 Energy calculation
MULTICAL® 602 calculates energy based on the formula in EN 1434-1:2007 in which the international
temperature scale from 1990 (ITS-90) and the pressure definition of 16 bar is used.
The energy calculation can in a simplified way be expressed as: Energy = V × ΔΘ × k.
The calculator always calculates energy in [Wh], and then it is converted into the selected measuring unit.
× ΔΘ × k × 1000
E [Wh] =
V
E [kWh] =
E [Wh] / 1,000
E [MWh] =
E [Wh] / 1,000,000
E [GJ] =
E [Wh] / 277,780
E [Gcal] =
E [Wh] / 1163,100
V
is the supplied (or simulated) water volume in m3. E.g. if a CCC code = 119 is used, the calculator will be
programmed to receive 100 pulses/liter. E.g. if 10,000 pulses are added this corresponds to 10,000/100 =
100 liters or 0.1 m3.
ΔΘ
is the temperature difference measured, e.g. ΔΘ = flow temperature – return flow temperature. Please
note, that various temperatures are used to calculate ΔΘ as MULTICAL® 602 calculates various different
energy types. Both in the display and during data reading each energy type is uniquely defined, e.g.:
Heat energy: E1 = V1(T1-T2)k
k
Cooling energy: E3 = V1 (T2-T1)k
is the thermal coefficient of water which is calculated on the basis of formula in EN 1434-1:2007 (identical
with the energy formula in OIML R75-1:2002). For control calculations Kamstrup can supply an energy
calculator (available on intranet):

6.2.2 E8 and E9
E8 and E9 are used as calculation basis for calculating volume based average temperatures in flow and return
pipe, respectively. For each integration (every 0.01 m3 for qp 1.5 m3/h) the registers are accumulated with the
product of m3 × °C, for such purposes E8 and E9 is a suitable basis for calculating volume based average
temperatures.
E8 and E9 can be used for average calculation in any period of time as long as the volume register is read at the
same time as E8 and E9.
E8= m3 × tF E8 is accumulated with the product of
m3 × tF
E9 = m3 × tR E9 is accumulated with the product of m3 × tR

MULTICAL® 602
TECHNICAL DESCRIPTION
6.3 Calculator with two flow sensors
MULTICAL® 602 can be used in various applications with two flow sensors, e.g. leak surveillance or
open systems. When two ULTRAFLOW® are direct connected to one MULTICAL® 602, a close electric
coupling between the two pipes ought to be carried out as a main rule. If the two pipes are installed in a
heat exchanger, close to the flow sensors, however, the heat exchanger will provide the necessary
electric coupling.
Electric coupling
• Forward and return pipes are closely electrically coupled
• No welded joints occur
In installations where the electric coupling cannot be carried out, or where welding in the pipe system
can occur, the cable from one ULTRAFLOW® must be routed through a Pulse Transmitter with galvanic
separation before the cable enters MULTICAL® 602.
• Forward and return pipes are not necessarily closely coupled
• Electric welding *) can occur
*)
Electric welding must always be carried out with the earth pole closest to the welding point. Damage
to meters due to welding is not comprised by our factory guarantee.

If MULTICAL® 602 has been supplied as a combined heat/cooling meter (meter type 6xx), it measures heat energy
(E1) at a positive temperature difference (T1 > T2), whereas it measures cooling energy (E3) at a negative
temperature difference (T2 > T1). Temperature sensor T1 (with a red type sign) must be installed in the hydraulic
forward pipe, whereas T2 (with a blue type sign) is installed in the return pipe.
If the current T1 exceeds, or equals θhc only heat energy can be measured. If the current T1 is lower than or equals
θhc only cooling energy can be measured.
θhc is the temperature point used to change between heat and cooling measurement. θhc is configurable in
temperature range 0.01…180.00°C.
In combined heat/cooling meters θhc should correspond to the highest occurring flow pipe temperature in
connection with cooling, e.g. 25°C. If the meter is to be used for ”purchase and sale of heat”, θhc is set at
200.00°C, which cancels the θhc function.
The change between heat and cooling measurement involves no hysteresis (Δθhc = 0.00K).
θhc is configured by means of METERTOOL (see paragraph 13.2). θhc is also mentioned as H/C change-over.

MULTICAL® 602
TECHNICAL DESCRIPTION
6.5 Flow measurement, V1 and V2
MULTICAL® 602 calculates current water flow according to two different principles depending on the connected
flow sensor type:
6.5.1 Fast volume pulses (CCC > 100)
The current water flow for fast volume pulses is calculated, without average determination, as the number of
volume pulses per 10 sec. multiplied by a scaling factor.
q = (pulses/10 sec. x flow factor)/65535 [l/h] or [m3/h]
Example:
-
ULTRAFLOW® qp 1.5 m3/h with 100 pulses/l (CCC=119), flow factor = 235926
-
Current water flow = 317 l/h corresponding to 88 pulses/10 sec.
q = (88 x 235926)/65535 = 316.8 which is shown in the display as 316 [l/h]
Current water flow in V1
6.5.2 Resolution of the actual flow rate (CCC > 100)
The display resolution of the actual flow rate can be derived from the flow factor and the number of decimals.
Example 1:
-
ULTRAFLOW® qp 1.5 m3/h with 100 pulses/l (CCC=119), flow factor = 235926
Resolution = 235926/65535 = 3.6 which is shown in the display as 3 [l/h]
Example 2:
-
FUS380 Qs 75 m3/h with 1 pulses/l (CCC=201), flow factor = 235926
Resolution = 235926/65535 = 3.6 which is shown in the display as 3.6 [m3/h]
6.5.3 Slow volume pulses (CCC = 0XX)
The current water flow for slow volume pulses (typically from flow sensors with a Reed switch) is calculated
without average determination as a scaling factor divided by the period of time between two volume pulses.
q = flow factor/(256 x period in sec.) [l/h] or [m3/h]
Example:
-
Mechanical flow sensor Qn 15 qp m3/h with 25 l/pulse (CCC=021), flow factor = 230400
-
Current water flow = 2.5 m3/h corresponding to 36 sec. in the period of time between 2 pulses
q = 230400/(256 x 36) = 25, which is shown in the display as 2.5 [m3/h]
V1 and V2 must be the same type (either quick (CCC >100) or slow (CCC=0XX)) but can have different qp-codings
(CCC).
Using top modules 67-02 or 67-09, V1 and V2 must have identical qp-codings (CCC).
The actual flow rate on the display will be shown a ”0”, when the period between pulses exceed 15 min.

MULTICAL® 602
TECHNICAL DESCRIPTION
6.6 Power measurement, V1
MULTICAL® 602 calculates the current power based on the current water flow and the temperature difference
measured at the last integration based on following formula:
P = q (T1 – T2) x k [kW] or [MW]
where ”k” is the water's heat coefficient that is constantly calculated by MULTICAL® 602 according to
EN 1434:2007.
Example:
-
Current water flow, q = 316 l/h and flow sensor is placed in return pipe
-
T1 = 70.00°C and T2 = 30.00°C, k-factor is calculated for 1.156 kWh/m3/K
P = 0.316 (70-30) x 1.156 = 14.6 [kW]

TECHNICAL DESCRIPTION
6.7 Min. and max. flow and power, V1
MULTICAL® 602 registers both minimum and maximum flow and power both on a monthly and on a yearly basis.
These values can be read in full via data communication. In addition, a small number of monthly and yearly
registers can be read on the display depending on the selected DDD code.
Min. and Max. registration comprises following flow and power values including date.

All max. and min. values are calculated as largest and smallest average of a number of current flow or power
measurements. The average period used for all calculations are selected in the interval 1…1440 min. in jumps in
1 min. (1440 min. = 1 full day).
The average period and target date are stated in connection with orders or re-configured by means of METERTOOL.
Where nothing has been stated when the order was placed the average period is set at 60 min. and the target
date is set at the standard applying for the country code used.
In connection with commencement of a new year or month the max. and min. values are stored in the data logger
and the current max. and min. registers are "reset" according to the selected target date and the internal clock
and calendar of the meter.
"Reset" is made by putting the max. value at zero and min. value at 10000.0 kW at e.g. CCC=119.
If the max. or min. registration is used for billing purposes, we recommend to supplement MULTICAL® 602 with a
top module containing real time clock and battery back-up.

MULTICAL® 602
TECHNICAL DESCRIPTION
6.8 Temperature measurement
MULTICAL® 602 has a high resolution analog/digital converter that measures the temperatures T1, T2 and T3 with
a resolution of 0.01°C (T3 is not available on meters with 4-wire sensor inputs). The same measuring circuit is
used for all 3 temperature inputs to obtain the lowest possible measuring error on the temperature difference.
Prior to each temperature measurement an automatic adjustment of the internal measuring circuit is made on the
basis of integral reference resistances at 0°C and 100°C, respectively. This ensures a very good accuracy and a
very stable long-term operation.
Current T1
Temperature measurings are made in connection with each integration (energy calculation) and every 10 sec.
when the display shows temperature. The measuring circuit has a temperature range of 0.00°C…185.00°C. In
case of a disconnected temperature sensor the display shows 200.00°C and in connection with a short-circuited
temperature sensor it shows 0.00°C. In both cases the info code for sensor error will appear.
To reduce the influence from the mains frequency which can e.g. be inducted to long sensor cables, double
measurings are made with a delay of ½ period , and the average of the 2 measurings make up the temperature
measurement used for calculation and display. Supressing of the mains frequency is optimised to either 50 Hz or
60 Hz depending on the selected country code.
6.8.1 Measuring current and power
Measuring current is only sent through the temperature sensors in the short period of time it takes to measure the
temperature. However, the effective power that is consumed in the sensor elements is minimal and the influence
on the self-heating of the temperature sensors is typically less than 1/1000 K.

6.8.2 Average temperatures
MULTICAL® 602 constantly calculates the average temperatures for flow and return (T1 and T2) in the entire °C
range and the background calculations E8 and E9 (m3 x T1 and m3 x T2) are made for each energy calculation (e.g.
for each 0.01 m3 for qp 1.5 meter size), whereas the display value is updated every day. Thereby the average
calculations are weighted according to volume and can therefore be used for control purposes.

6.8.3 Programmed temperatures
The temperatures T3 and T4 can be programmed in the memory of the calculator, and these temperatures can be
used for calculating energy with fixed temperature reference, as used in connection with the calculations of the
energy types E4, E5, E6 and E7 (see the application drawings in paragraph 6.2)
The temperatures can be programmed when placing orders or by means of METERTOOL in the range 0.01…180°C,
once the meter is installed.

TECHNICAL DESCRIPTION
6.9 Display functions
MULTICAL® 602 is equipped with a clear LC display including 8 digits, units of measurement and information
panel. In connection with energy and volume readings 7 digits and the corresponding units of measurement are
used, whereas 8 digits are used when e.g. a meter number is shown.
As a starting point the display shows the accumulated energy. When the push buttons are activated the display
reacts immediately by showing other readings. The display automatically returns to energy reading 4 minutes
after last activation of the push buttons.
6.9.1 Primary and secondary readings
The upper button is used to switch between the primary readings of which the consumers typically use the first
primary readings in connection with self-reading for billing purposes.
The lower push button is used to show secondary information on the primary reading that has been selected.
Example: When the primary reading selected is "Heat energy" the secondary readings will be yearly data and
monthly data for heat energy.

6.9.2 Display structure
Below diagram shows the display structure with up to 20 primary readings and a number of secondary readings
under most primary readings. The number of secondary readings for yearly data and monthly data has been laid
down under the DDD code. If nothing is informed in connection with placing the order, the reading is set at 2
yearly data and 12 monthly data. The target date is set at the standard valid for the country code used.
As the display is configured according to the needs of the customer (by selecting DDD code), the display will
usually contain fewer readings than shown below.

6.10 Real Time Clock (RTC)
MULTICAL® 602 has built-in real time clock and battery backup. This is valuable for applications where correct
date/time in data loggers as well as time-controlled tariffs are important. The battery will ensure the RTC function
for at least 3 years without power during the entire lifetime of MULTICAL® 602. This small battery will only back-up
the RTC, meaning that the display will go blank, when the main supply or main battery is off.
If a top module with RTC is mounted, the top module’s RTC will not have any effect on the meter’s own RTC.

TECHNICAL DESCRIPTION
6.11 Info codes
MULTICAL® 602 constantly surveys a number of important functions. Where serious errors have occured in the
measuring system or in the installation, a flashing "INFO" will appear in the display while the error exists. The
“INFO” panel will flash for as long as the error exists no matter which reading is selected. The " INFO " panel will
automatically turn off, when the source of error has been corrected.
6.11.1 Examples of info codes on the display
Ex. 1
Flashing ” INFO”
If the info code exceeds 0 a flashing " INFO " will
appear in the information panel.
Ex. 2
Current info code
When the upper (primary) push button is activated
several times the current info code can be shown on
the display.
Ex. 3
Info event counter
- indicates how many times the info code has been
changed.
Ex. 4
Info logger
By pressing the lower push button once more the
data logger for the info code is displayed.
First, the date of the first change is displayed …
…then the info code appearing on that particular
date is displayed. In this case there has been a
"bursting alarm" on 4th January 2006.
The data logger stores the last 50 changes, of which
the last 36 changes are shown in the display. All 50
changes can be read by means of LogView.
Time, E1 (heat energy) and E3 (Cooling energy – if available) will be logged when the info code is changed.
Naturally, the info code will still be logged during changed info codes. To read out Time and E1 together with the
info code it is necessary to use LogView.
In addition, the info code is stored in the hourly logger, the daily logger, the monthly logger and the yearly logger
for diagnostic purposes.

Info code 1 will be logged when the mains supply/main battery is switched OFF and Info code 1 will be deleted
when the mains supply/main battery is switched ON. Thereby the time without power can be retrieved from the
logger data.
If several info codes appear at the same time the sum of the info codes is shown. E.g. if both temperature sensors
are outside measuring range, info code 12 will appear.
During configuration at the factory the individual info - active or passive - are set and in this way a standard heat
meter not using T3, cannot display info code 32.

6.11.3 Transport mode
When the meter leaves the factory it is in transport mode, and the info codes are only active on the display and
not in the data logger. This prevents both ”info event” to increment and the storage of non relevant data in the
info logger. When the meter has summed up the volume register for the first time after installation the info code is
automatically set at active.

TECHNICAL DESCRIPTION
6.12 Tariff functions
MULTICAL® 602 has 2 extra registers TA2 and TA3 to accumulate heat energy or cooling energy (EE=20
accumulates volume) in parallel to the main register based on a programmed tariff condition. No matter which
tariff form is selected the tariff registers are indicated as TA2 and TA3 in the display.
The main register is always accumulated as it is considered a legal billing register, irrespective of the selected
tariff function. The tariff conditions TL2 and TL3 are monitored before each integration. When the tariff conditions
are fulfilled the consumed heat energy is counted in either TA2 or TA3, in parallel to the main register.

Number of integrations
To each tariff function two tariff conditions, TL 2 and TL3 are connected, which are always used in the same tariff
type. Therefore, it is not possible to "mix" two tariff types.
Example: EE=11 (Power tariff)
TA2 shows the consumed energy…

6.12.1 Tariff types
Below table indicates which tariff types MULTICAL® 602 can be configured to:
•
•
•
•
Please note that only tariff No. 20 can be used in a combined heat / cooling meter. All other tariffs can only be
used with either a heat meter or a cooling meter. The meter cannot distinguish heat energy (E1) from cooling
energy (E3) and vice versa.
EE=00 No tariff active
If the tariff function should not be used, select the set-up for EE=00.
However, the tariff function can be made active at a later date by a reconfiguring the function by means of
METERTOOL for MULTICAL® 602. See paragraph Fejl! Henvisningskilde ikke fundet. METERTOOL.
EE=11 Power controlled tariff
When the current power is higher than TL2, but lower than/equal to TL3, the energy is counted in TA2 in parallel to
the main register. If the current power exceeds TL3, the energy is counted in TA3 in parallel to the main register.
P ≤ TL2
Counting in main register only
TL3 ≥ P > TL2
Counting in TA2 and the main register
P > TL3
Counting in TA3 and the main register
TL3 > TL2
When setting up data TL3 must always be higher than TL2. Among other things the power controlled tariff is used
as a basis for calculating the individual consumer’s connection costs. Furthermore, this tariff form can provide
valuable statistical data when the energy supplier evaluates new installation activities.

5512-931 GB/09.2011/Rev. B1
MULTICAL® 602
TECHNICAL DESCRIPTION
EE=12 Flow controlled tariff
When the current water flow is higher than TL2 but lower than/equal to TL3, the energy is counted in TA2 in
parallel to the main register. If the current water flow becomes higher than TL3, the energy is counted in TA3 in
parallel to the main register. When setting up data, TL3 must always be higher than TL2.
q ≤ TL2
Counting in main register only
TL3 ≥ q > TL2
Counting in TA2 and the main register
q > TL3
Counting in TA3 and the main register
TL3 > TL2
Among other things the flow controlled tariff is used as a basis for calculating the individual consumer’s
connection costs. Furthermore, this tariff form provides valuable statistical data when the energy supplier
evaluates new installation activities.
When the power or flow tariff is used it is possible to get a total overview of the total consumption compared to
the part of the consumption, that is used above the tariff limits.
EE=13 Differential temperature tariff (Δt)
When the current T1-T2 (Δt) is lower than TL2, but higher than TL3, the energy is counted in TA2 in parallel to the
main register. If the current cooling drops to less than/equal to TL3, the energy is counted in TA3 in parallel to the
main register.
Δt ≥ TL2
Counting in main register only
TL3 < Δt < TL2
Counting in TA2 and the main register
Δt ≤ TL3
Counting in TA3 and the main regiser
TL3 < TL2
When setting up tariff limits TL3 must always be lower than TL2.
The T1-T2 tariff can be used to form the basis for a weighted user payment. Low Δt (small difference between flow
and return flow temperatures) is uneconomical for e.g. the heat supplier.
EE=14 Flow temperature tariff
When the current flow temperature (T1) is higher than TL2, but lower than/equal to TL3, the energy is counted in
TA2 in parallel to the main register. If the current flow temperature becomes higher than TL3, the energy is
counted in TA3 in parallel to the main register.
T1 ≤ TL2
Counting in main register only
TL3 ≥ T1 > TL2
Counting in TA2 and the main register
T1 > TL3
Counting in TA3 and the main register
TL3 > TL2
When setting up data TL3 must always be higher than TL2.
The flow temperature tariff can form the basis of billing of those customers who are guaranteed a given flow
temperature. When the “guaranteed” minimum temperature set at TL3, the calculated consumption is
accumulated in TA3.
5512-931 GB/09.2011/Rev. B1
53
MULTICAL® 602
TECHNICAL DESCRIPTION
EE=15 Return temperature tariff
When the current return temperature (T2) is higher than TL2 but lower than/equal to TL3, the energy is counted in
TA2 in parallel to the main register. If the current return temperature becomes higher than TL3, the energy is
counted in TA3 in parallel to the main register.
T2 ≤ TL2
Counting in main register only
TL3 ≥ T2 > TL2
Counting in TA2 and the main register
T2 > TL3
Counting in TA3 and the main register
TL3 > TL2
When setting up data TL3 must always be higher than TL2.
The return temperature tariff can form the basis of a weighted user payment. A high return flow temperature
indicates insufficient heat utilization which is uneconomical for e.g. the heat supplier.
54
5512-931 GB/09.2011/Rev. B1
MULTICAL® 602
TECHNICAL DESCRIPTION
EE=19 Time-controlled tariff
The time-controlled tariff is used for time division of the heat consumption. If TL2 = 08:00 and TL3 = 16:00 the
consumption of the entire day from 08:00 till 16:00 will be accumulated in TA2, whereas the consumption of the
evening and the night from 16:01 till 07:59 will be accumulated in TA3.
TL2 must have a lower number of hours than TL3.
TL 3 ≥ Clock ≥ TL2
Counting in TA2 and the main register
TL 2 > Clock > TL3
Counting in TA3 and the main register
TL3 > TL2
Among other things the time tariff is suitable for billing in housing sectors close to industrial sectors with a large
consumption of district heating and for billing industrial customers.
EE=20 Heat/cooling volume tariff
The heat/cooling volume tariff is used for dividing volume into heat and cooling consumption. TA2 accumulates
the volume consumed together with E1 (heat energy) and TA3 accumulates the volume consumed together with
E3 (cooling energy).
T1 ≥ T2
Volume is accumulated in TA2 and V1
T2 > T1
Volume is accumulated in TA3 and V1
TL2 and TL3 are
not used
In connection with combined heat/cooling measurement the total volume in the V1 register is accumulated,
whereas the heat energy is accumulated in E1 and the cooling energy in E3. The heat/cooling tariff divides the
consumed volume into heating and cooling volume.
EE=20 should always be selected together with combined heat/cooling meters, type 602-xxxxxxxx-6xx.
EE=21 PQ tariff
The PQ tariff is a combined power and flow tariff. TA2 functions as a power tariff and TA3 as a flow tariff.
P ≤ TL2 and q ≤ TL3
Counting in the main register only
P > TL2
Counting in TA2 and the main register
TL2 = power limit (P)
q > TL3
Counting in TA3 and the main register
TL3 = flow limit (q)
P > TL2 and q > TL3
Counting in TA2, TA3 and the main register
Among other things the PQ tariff is used for customers paying a fixed duty based on max. power and max. flow.

MULTICAL® 602
TECHNICAL DESCRIPTION
6.14 Leak surveillance
6.14.1 District heating installations
The leak surveillance system is primarily intended for directly connected district heating installations, i.e.
installations without heat exchanger between the district heating network and the heating system of the housing.
The surveillance system consists of two water meters based on the ultrasonic principle placed in both flow and
return pipe, and of temperature sensors in both pipes. In addition, the electronic unit MULTICAL® 602, which in
addition to calculating the heat energy also surveys the mass difference (temperature compensated volume) that
may appear between flow and return pipe.

If a difference of more than 20% of the measuring range (corresponding to 300 l/h in a single-family house) is
registered, an alarm will be sent within 120 sec. via remote communication.
Small leaks from 15 kg/h and upwards for qp 1.5 m3/h are under surveillance on the basis of a 24-hour average
to rule out incorrect alarms as a consequence of air pockets and fast flow changes e.g. from hot-water
exchangers.

NB: M=2 is a default value when leak surveillance is used. Higher degrees of sensitivity, e.g. M=4 is only possible
by means of METERTOOL. Please see 3.8.1 for an example of how the sensitivity is calculated.
Info codes for leak/bursting are only active when M > 0 or N > 0, respectively.

TECHNICAL DESCRIPTION
Example: The curve below illustrates the difference between Mass V1 and Mass V2 in an extract of 60 days
before the leak in a floor heating pipe was the reason for a leak alarm. As will appear from below, there is a
fluctuation of approx. ± 1 kg/hour in the first 43 days which is a normal fluctuation for installations without leaks.

6.14.2 District heating bursting
Every 30 sec. the current flow in the flow pipe is compared with that in the return flow pipe. If the difference at 4
measurings in a row (120 sec.) is larger than 20% of the nominal flow info = 00512 and a "bursting alarm" will be
sent via remote communication.
6.14.3 Cold-water systems
In addition to above functions MULTICAL® 602 can be connected to the pulse signal from the cold-water meter of
the house. In this way it can survey the cold-water consumption. A flushing toilet cistern, leaky heating coils in
the water tanks or other leaks will cause that impulses from the cold-water meter are received 24 hours a day.
If MULTICAL® 602 does not register e.g. at least one continous hour/day without pulses from the water meter, this
is a sign of a leak in the water system and an alarm will be sent via remote communication.

NB: N=2 is a default value in connection with leak surveillance. Higher degree of sensitivity, e.g. N=3 is only
possible if using METERTOOL. Infocodes for leak/bursting are only active when M > 0 or N > 0, respectively.
6.14.4 Receiving alarm messages
When the meter has registered a leak or bursting it will send an alarm message to a receiving station, where
incoming alarms are handled on the basis of an encoded action pattern that is laid down for each individual
customer, e.g. starting with an SMS message to the customer’s mobile phone. At the same time the utility on duty
receives the message. Regular data readings from MULTICAL® 602 to the receiving station/monitoring center
ensure that defective remote readings, if any, are detected.

TECHNICAL DESCRIPTION
6.14.5 Surveillance, but no automatic blocking
The leak surveillance system is based on installation at a large number of private district heating customers’.
Usually, the individual utility installs and maintains the leak surveillance, integrated with the compulsory heat
metering at all district heating customers in their area. In this way, the individual private district heating
customers neither maintain the system nor perform other technical tasks in connection with the installed leak
surveillance system, and the surveillance system must not imply an increased risk of faulty blocking that may
lead to frost bursts. As a consequence of this the entire system must have a reliability that ensures operation for
12 years without maintenance. As neither thermally nor electrically activated shut-off valves can be expected to
have such a long lifetime it will not be possible to use automatic blocking.
6.14.6 First day after reset
The first day after installation (when the meter has had no supply voltage) no infocodes will be set and no alarms
will be sent in case of calculated district heating or cold-water leak.
This limitation has been introduced to avoid wrong alarms as a result of the installation and the shortened
metering period.
The alarm function can be tested via remote communication by pressing both push buttons simultaneously, until
a ”Call” appears in the display.

6.15 Reset functions
6.15.1 Resetting the hour counter
As the hour counter usually is used to control that the meter has been
in operation in the entire billing period (e.g. 1 year = 8760 hours) the
district heating supplier must always be informed which meters have
had their hour counter reset.
The operational hour counter can only be reset via the front bottons.
Please see 6.18.
6.15.2 Resetting data loggers
Separate reset of data loggers, info loggers, max. & min. loggers (without resetting the legal registers) are only
possible by means of METERTOOL. See paragraph 13 for further details.
6.15.3 Resetting all registers
Resetting all legal and non-legal registers including all data loggers, info loggers, max. & min. loggers can only be
made by using METERTOOL or via NOWA, if the verification seal is broken and the internal “Total programming
lock” is short-circuited. As the verification seal is broken, this can only be made at an accredited laboratory.
Following registers are reset:
All legal and non-legal registers including all data loggers, info loggers, max. & min. loggers (max. values are set
at zero, whereas min. values are set at 100000).
After reset ”Date” is set at 2000.01.01 and is then changed to current date/time of the PC used for the task.
Remember to check correct date/time (technical standard time = “winter-time”) on the PC before the reset
function is initiated.
6.16 SMS Commands
MULTICAL® 602 can be read by means of an SMS. In order to do so, a GSM-module (68G6xxxxx) fitted with a SIMcard must be connected to the meter. To read the meter you send an SMS from a mobile phone direct to the
meter. Subsequently, you receive a reply with the following values:
•
Acc. energy: [kWh], [MWh], [GJ] or [Gcal]
•
Current power: [kW] or [MW]
•
Hour counter
•
Meter number. It is also possible to read the modem’s signal strength by means of an SMS. You receive a
reply with the modem’s current signal strength on a scale of 0 to 31, the best value being 31. The signal
strength must be minimum 12. See the examples on the next page.
•
There are different SMS-commands to get additional data via SMS: Pressure, I/O-status, Signal strength
(please see Installation Manual for further information)
NOTE: SMS commands must be written in either capital letters or small letters, i.e. an SMS command must not
include a mixture of capital and small letters.

MULTICAL® 602
TECHNICAL DESCRIPTION
7 Flow sensor connection
MULTICAL® 602 can be used with up to 4 pulse inputs, of which V1 and V2 are used for energy calculation and
leak surveillance, whereas VA and VB are used to accumulate pulses e.g. from tap-water meters and electricity
meters.
V1 and V2 can either be used for fast pulses (CCC > 100) or for slow pulses (CCC = OXX). Fast and slow pulses
cannot be used simultaneously.
7.1 Volume inputs V1 and V2
MULTICAL® 602 can be connected to one or two flow sensors depending on the required application. Typical heat
installations with one flow sensor are always connected to V1 irrespective if this flow sensor is installed in flow
pipe or return pipe.
Almost all available flow sensor types with pulse output can be connected as the standard connection PCB
receives pulses from both electronic and mechanical meters. In addition, a connection PCB that receives 24 V
active pulses is also available.
7.1.1 Flow sensor with transistor- or FET output c
Typically, the signaller is an optocoupler with a transistor or a FET outpt. V1 is connected to terminal 10(+) and
11(-), V2 is connected to terminals 69(+) and 11(-). Terminal 9 is not used in this application.
The leak current in the transistor or FET output must not exceed 1μA in OFF state and there must be max. 0.4 V in
ON state.
A suitable CCC code must be selected with the same number of pulses/liter as the flow part, and for this flow
sensor type the CCC code must be CCC > 100.
Example: CCC=147 fits an electronic meter with 1 pulse/liter and qp of 150 m3/h.
7.1.2 Flow sensor with Reed switch output d
The signaller is a Reed switch typically mounted on vane wheel or Woltmann meters, or a relay output from e.g. a
magnetic inductive flow sensor. V1 is connected to the terminals 10(+) and 11(-), V2 is connected to the
terminals 69(+) and 11(-). Terminal 9 is not used in this application.
The leak current must not exceed 1μA in OFF state and there must be max. 10 kΩ in ON state.
A suitable CCC code must be selected with the same number of pulses/liter as the flow part, and for this flow
sensor type the CCC code must be in the range 010 ≤ CCC ≤ 022.
Example: CCC=012 fits a mechanical flow sensor with 100 liter/pulse. Flow sensors with Qmax. in the range
10…300 m3/h can use this CCC code.

7.1.3 Flow sensor with active output supplied from MULTICAL® e
This connection is used both together with Kamstrup’s ULTRAFLOW® and Kamstrup’s electronic pick-up units for
vane wheel meters. The power consumption in these units is very low and is adapted to MULTICAL®’s battery
lifetime.
A suitable CCC code must be selected with the same number of pulses/litre as the flow part, and for this flow
sensor type the CCC code must be CCC > 100.
Example: CCC=119 fits an electronic meter with 100 pulses/litre and typical qp is 1.5 m3/h.
V1 and V2 are connected as shown in below diagram.

7.1.3.1
Use of Pulse Transmitter between ULTRAFLOW® and MULTICAL®
In general it is permissible to use up to 10 m cable between MULTICAL® and ULTRAFLOW®. If longer cable is
required, a Pulse Transmitter can be inserted between ULTRAFLOW® and MULTICAL®. In this way the cable length
can be extended up to 50 m.
When a Pulse Transmitter is used between ULTRAFLOW® and MULTICAL®, volume pulses from the flow meter will
be transferred to the calculator. However, the calculator is unable to data communicate with the flow meter. In
order to avoid erroneous info codes it is, therefore, necessary to deselect the info codes, which are based on data
communication between MULTICAL® and ULTRAFLOW® 54 (Info = 16-1024-2048-128-4096-8192-16384-32768).
The above-mentioned info codes can be deselected by means of the PC-program METERTOOL, either by changing
from CCC-code 4xx to 1xx, or by using the ”Info code setup” function under ”Utility”. See paragraph 13.2.3 Info
code setup.

MULTICAL® 602
TECHNICAL DESCRIPTION
7.3 Pulse inputs VA and VB
In additions to the pulse inputs V1 and V2 MULTICAL® 602 has two extra pulse inputs, VA and VB, to collect and
accumulate pulses remotely, e.g from cold-water meters and electricity meters. The pulse inputs are physically
placed on the ”base modules” as for instance on the ”data/pulse input module” that can be placed in the
connection base, however, accumulation and data logging of values are made by the calculator.
The pulse inputs VA and VB function independantly of the other inputs/outputs and thereby they are not included
in any energy calculations.
Both pulse inputs are constructed identically and can individually be set up to receive pulses from water meters
with max. 1 Hz or pulses from electricity meters with max. 3 Hz.
Configuration to correct pulse value is made at the factory on the basis of order information or are configured by
means of METERTOOL. See paragraph 3.6 concerning configuration of VA (FF codes) and VB (GG codes).
MULTICAL® 602 registers the accumulated consumption for the meters connected to VA and VB and stores the
registers every month and every year on the target date. To facilitate the identification during data reading it is
also possible to store the meter numbers for the two meters that are connected to VA and VB. Programming is
made by means of METERTOOL.
The registers that can both be read on the display (by selecting a suitable DDD code) and via data communication
contains the following information as well as date of yearly and monthly data:
Registration type:

8.2 Cable influence and compensation
8.2.1
2 wire sensor set
Small and medium-sized heat meters only need a relatively short temperature sensor length, and the 2 wire
sensor set can be used with the advantage of easy installation.
The cable length and the cross sectional area must always be identical for the 2 sensors used as a temperature
sensor pair for a heat meter. The length of the cable sensors must neither be shortened nor extended.
The limitations attached to using the 2 wire sensor set according to EN 1434-2:2007 are stated in below table.

8.2.2 4 wire sensor set
For installations requiring longer cable lengths than stated in above table, we recommend a 4 wire sensor set and
a MULTICAL® 602 type 602-B with 4 wire connection.
The 4 wire construction uses two conductors for testing current and the two other conductors for measuring
signal. In this way, the construction will in theory not be affected by long sensor cables. However, in practice
cables longer than 100 m should not be used. We recommend to use 4 x 0.25 mm2.
5512-931 GB/09.2011/Rev. B1
75
MULTICAL® 602
TECHNICAL DESCRIPTION
The connection cable should have an outside diameter of 5-6 mm to obtain optimal tightening in both
MULTICAL® 602 and in the cable gland on the 4 wire sensor. The insulation material/cover of the cable should be
selected based on the max. temperature in the installation. PVC cables are typically used up to 80°C and in
connection with higher temperatures silicone cables are often used.
4 wire sensor set from Kamstrup has an interchangeable sensor pocket and is available in the lengths 90, 140
and 180 mm.

TECHNICAL DESCRIPTION
8.3 Pocket sensors
The Pt500 cable sensor is constructed with a 2 wire silicone cable and closed with a shrinked-on stainless steel
tube with a diamenter of ø5.8 mm that protects the sensor element.
The steel tube is fitted in a sensor pocket (pocket) which has an inside diameter of ø6 and an outside diameter of
ø8 mm. The sensor pockets are supplied with an R½ (conical ½”) connection in stainess steel with a length of
65, 90 or 140 mm. The sensor construction with separate pocket allows replacement of sensors without turning
off the water flow. The large selection of pocket lengths also ensures that the sensors can be fitted in all pipe
sizes.
The plastic tube on the sensor
cable is placed opposite the seal
screw and the screw is tightened
lightly by hand before sealing.

TECHNICAL DESCRIPTION
8.4 Pt500 short direct sensor set
The Pt500 short direct sensor is constructed according to the European standard for thermal heat meters
EN 1434-2. The sensor is constructed for fitting directly in the measuring medium, i.e. without sensor pocket. In
this way an extremely fast response time on temperature changes from e.g. domestic water exchangers is
obtained.
The sensor is based on a 2 wire silicone cable. The sensor tube is made of stainless steel and has a diameter of
ø4 mm at the tip where the sensor element is placed. Fitting can also be made directly in many flow sensor types,
which reduces the installation costs.
The sensor is fitted in special T-sections, that is
available for ½”, ¾” and 1” pipe installations.
Figure 6
In addition, the short direct sensor is fitted by
means of a R½ or R¾ for M10 nipple in a
standard 90° tee.
Figure 7
To obtain the best serviceability during meter
replacements, the short direct sensor can be
placed in a ball valve with a sensor connecting
piece.
Ball valves with a sensor connecting piece are
available in G½, G¾ and G1.

The above supply modules are all included in the extensive type test made on MULTICAL® 602. Within the
frameworks of the type approval, the CE declaration and the factory guarantee, no other types of supply modules
must be used than those mentioned above.
9.1 Integral D-cell lithium battery
A lithium D-cell battery (Kamstrup type 66-00-200-100) must be used for the meter. The battery is placed at the
right in the base unit and can easily be replaced just by using a screwdriver.
The battery lifetime partly depends on the temperature to which the battery is exposed and partly of the selected
meter application.

9.7 Exchanging the supply unit
The power supply unit for MULTICAL® 602 can be exchanged from mains supply to battery or vice versa as the
needs at the utility change. In this way, mains supplied meters can be exchanged for battery meters with
advantage in connection with buildings in the course of construction, as the mains supply may be unstable or
lack periodically.
Exchange from battery to mains supply does not require reprogramming, as MULTICAL® 602 does not contain an
information code for worn out batteries.
However, exchange from mains supply to battery must not be made on MULTICAL® 602 with following base

TECHNICAL DESCRIPTION
9.8 Mains supply cables
MULTICAL® 602 is available with mains cables H05 VV-F for either 24 V or 230 V (l=1.5 m):
Mains cable, type 5000-286 (2x0.75 mm²), max. 6 A fuse
”H05 VV-F” is the designation for a heavy PVC cable, that stands max. 70°C. The supply cable must therefore be
installed with a sufficient distance to hot pipes and the like.
9.9 Back-up of data during power down
An early warning circuit and corresponding software is added, securing safety back-up of all main registers during
power down. In fact, this will function as the hourly data back-up, but also during power down. This will ensure
that the meter always starts up with the same display values as before the power break.
This will be effective for both 24V and 230V power break and also when the top part of MULTICAL® 602 is
removed from the base, or in case of a battery failure.
The battery has been constructed to maintain a constanct voltage level of 3.6 VDC ±0,1 V throughout its entire
life-time. Shortly before the battery’s energy is used up completely, the voltage falls. When the battery reaches
3.1 V the meter safety backs up. When the voltage is further reduced, ”bAt LO” is displayed to indicate that the
battery voltage of the meter is too low to carry out measurements. At 2.1 V info code = 1 is logged in the info
event logger with time and date, to make it possible to see when the battery’s energy has been completely used
up.

TECHNICAL DESCRIPTION
9.10 Danish regulations for connection of mains operated meters
Installation to electric mains operated equipment for consumption registration (www.sik.dk, safety notification
electric services no. 27/09, February 2009).
The consumption of energy and resources (electricity, heat, gas and water) of the individual consumer is to an
increasing extent registered by electronic meters, and often equipment for remote reading and remote control of
both electronic and non-electronic meters is used.
General regulations for carrying out installations must be observed. However, the following modifications are
permitted:
•
If meter or equipment for remote reading or remote control is double-isolated, it is not necessary to run
the protective conductor all the way to the connection point. This also applies if the connection point is a
plug socket provided that it is placed in a canning which is sealable or can be opened with key or tool
only.
If meter or equipment used for remote reading and remote control is connected to a safety transformer mounted
in the panel and direct connected to the branch conductor, no on-off switch or separate overcurrent protection in
either primary or secondary circuit is required, provided that the following conditions are fulfilled:
• The safety transformer must either be inherently short-circuit-proof or fail-safe
• The conductor of the primary circuit must either be short-circuit protected by the overcurrent protection of
the branch conductor or short-circuit safely run.
• The conductor of the secondary circuit must have a cross section of at least 0.5 mm² and a current value

MULTICAL® 602
TECHNICAL DESCRIPTION
11 Data communication
11.1 MULTICAL® 602 data protocol
Internally in MULTICAL® 602 the data communication is built up with a Kamstrup Meter Protocol (KMP) that both
gives a fast and flexible reading structure, and fulfils future demands on data reliability.
The KMP protocol is common for all Kamstrup consumption meters introduced in 2006 and later. The protocol is
used on the optical eye and via pins to the base module. Base modules with e.g. M-Bus interface uses the KMP
protocol internally and the M-Bus protocol externally.
The KMP protocol is constructed to handle point-to-point communication in a master/slave system (bus system, if
required) and is used for data reading of Kamstrup energy meters.
Software and parameter protection
The meter’s software is implemented into ROM and can after that not be changed neither deliberately nor nondeliberately. The legal parameters cannot be changed via data communication without breaking the legal seal
and short-circuiting the ”total programming lock”.
Software conformity
The check sum of the software, based on CRC16, is available via data communication and on the display.
Integrity and authenticity of data
All data parameters contain type, measuring unit, scaling factor and CRC16 check sum.
Each meter produced contains a unique identification number.
In the communication between master and slave two different formats are used. Either a data frame format or an
application knowledge.
•
Request from master to slave always takes place with a data frame.
•
Response from the slave either takes place with a data frame or an application knowledge.
The data frame is based on the OSI model, in which the physical layer, data link layer and the application layer
are used.

The protocol is based on half duplex serial asynchronous communication with the setup: 8 databits, no parity
and 2 stopbits. The data bit rate is 1200 or 2400 baud. CRC16 is used in both request and response.
Data is transferred byte for byte in a binary data format where the 8 databits thereby represent a byte data.
”Byte Stuffing” is used to extend the data domain.

MULTICAL® 602
TECHNICAL DESCRIPTION
11.1.2 Open data protocol
Companies who want to develop their own communication driver for the KMP protocol can order a demonstration
program with "open source code" in C# (.net based) as well as a detailed protocol description (in English
language).
11.2 MULTICAL® 602 communication paths
Physically, it is possible to communicate directly as shown below. Via destination addresses data
communication can be routed internally between modules and calculator.
11.3 Optical eye
For data communication via the optical interface an optical eye can be used. The optical eye must be located at
the front of the calculator, just above the IR-diode as shown on the photo below. Please note that the optical eye
contains a very powerful magnet that should be protected with the magnet protector when not in use.
Different variants of the optical eye can be found in the list of accessories (see chapter 3.2.2).
11.3.1 Current saver for the optical eye
The circuit around the optical eye has been improved by a magnet sensor that only allows current consumption
for the optical eye when a magnet (optical head) is attached to the meter.

TECHNICAL DESCRIPTION
12 Calibration and verification
12.1 High-resolution energy reading
If a need for high resolution of the energy reading arises during testing and verification it can be initialised as
follows:
-
Lift up the calculator top from the base unit and wait for the display to turn off
-
Press both push buttons simultaneously while the calculator top is placed in the base unit again and keep
pressing both push buttons until the display becomes active
-
The display now shows energy with a 0.1 [Wh] resolution until one of the push buttons are activated
The display example shows 345.4 [Wh] which corresponds to the energy accumulated at flow = 43.00°C and
return flow = 40.00°C and a return volume of 0.1 m3.
The high-resolution energy reading is displayed in Wh at a volume resolution of 0.01 m³
(qp 1.5 m³/h). In connection with large meters the energy shown must be multiplied by 10 or 100.
m3
0.001

x 100
The high-resolution energy can be used for both heat energy (E1) and for cooling energy (E3).
Hour counter and info-event counter are always reset when HighRes is provoked by pressing both keys in
connection with reset. Please be aware of pressing and releasing both keys simultaneously in order to avoid that
the meter returns to primary reading after some minutes.
12.1.1 Data reading of high-resolution energy
Data reading of the register ”HighRes” is possible with ID = 155.
The read value will show correct measuring unit and value irrespective of the meter size.
12.2 Pulse interface
During test and verification of MULTICAL® 602, where high resolution energy pulses are needed, the verification
adapter, type 66-99-275, can be used in the module area of the connection bracket.
The pulse interface gets serial data from MULTICAL® 602 every 7. sec. and converts these to high resolution
energy pulses with the same resolution as the high resolution display mode. (see chapter 12.1)

TECHNICAL DESCRIPTION
17 Appendix A - MULTICAL® 602 vs. previous meters
This paragraph briefly describes the compatibility with other/previous meters. The description is not final.
18.1 Kamstrup Meter Protocol (KMP)
MULTICAL® 602 uses Kamstrup’s Meter Protocol (KMP) and, thus, has the same communication platform as
MULTICAL® 402/61/601/801. KMP is used internally in the meter as well as via the optical eye and contact pins
for the base module. Thus, base modules with e.g. M-Bus interface use the KMP protocol internally and the M-Bus
protocol externally. Further information on the KMP protocol appears from paragraph 11.1.
18.2 M-Bus module with MULTICAL® III compatible data packet (67-00-29)
A variety of M-Bus modules are available for the Kamstrup MULTICAL® 61/601/801 meters. The contents of the
module’s M-Bus data package are similar to the data of the M-Bus modules for MULTICAL® III and MULTICAL®
Compact, allowing installation in older applications originally designed for e.g. MULTICAL® III.
The module can also be used together with the old 40-slave M-Bus Master with display from Kamstrup as well as
older regulators and reading software. The module is mounted in the meter’s module area and is
used for remote reading and programming of MULTICAL® 61/601/602/801.
18.3 SIOX module (602-00-64)
The SIOX module can be used in a series of Kamstrup’s meters, e.g. MULTICAL® 61/601/602/801, making it
possible to read meter data via the SIOX-bus. The SIOX-bus is a well-known bus-system, which has been used in
many meter relations. This module makes it possible to use MULTICAL® 61/601/602/801 in a SIOX-network.
18.4 MULTICAL® 66-C compatibility module (67-06)
Concerning MULTICAL® 601 a top module made MULTICAL® 601 data compatible with MULTICAL® 66-C, making it
possible to use a series of previous base modules for MULTICAL® 66-C in MULTICAL® 601 too. This module has
been discontinued and does not function together with MULTICAL® 602.
