Calculator features
1. Display
2. Calculation
MULTICAL® is equipped with a liquid crystal display with
8 numerical digits plus 3 alphanumeric characters. During normal operation the accumulated values for thermal
energy and water consumption are shown using 7 digits
and the relevant units of measurement using 3 alphanumeric characters (MWh, m3 etc.).
MULTICAL® uses volume-based energy integrations,
which means that the speed with which the calculator
calculates energy consumption is proportional to the
actual water flow. Depending on the size of the flow part,
integrations are performed with intervals from 0.001 m3
to 10 m3.
If a customer number is to be displayed, up to 11 digits
can be used, though without measuring unit.
The water quantity and degree of cooling are multiplied
using the k-factor from EN 1434, thus ascertaining the
amount of thermal energy. The meter is very accurate,
working with energy measurements in fractions. The
value displayed will, however, be rounded off. Fractions
remaining will be added to the next reading.
The accumulated value for thermal energy in MWh, kWh
or GJ is constantly displayed, the unit depends on the
individual programming. If the left or right front panel is
pressed, the display indicates as follows:

Heating and cooling energy is calculated in the same
manner. However, the total is stored in separate registers, depending on whether the temperature difference
is positive or negative. If the meter is used for combined
heating and cooling installations, the cooling power and
temperature difference will be indicated by a minus (-) in
the display.
The current flow calculation, l/h or m3/h, is performed
depending on the number of pulses generated by the
flow meter. The display is updated every 10 sec. when
connecting flow meters with electronical output
(CCC=1xx), though only every 30 sec. when connecting
mechanical flow meters with reed-switch (CCC=0xx).
Pulse separation (imp/l), which is determined by the
CCC-program, ensures that the flow meter and the calculator are totally compatible.
The actual power, kW or MW, is calculated on the basis of
the current values for: water flow, differential temperature and k-factor. The display value is updated every 10
sec. as is the water flow.
The peak power and peak flow are determined as the
average peak over a given period of time, typically 60
min., but can be configured in the range 1...1440 min.
3. Measuring temperature
Prior to each temperature measurement, the calculator
measures two internal reference resistors, compensating
for temperature and long-term drift. The temperatures of
T1, T2 and T3 are measured several times at different
points, thus ensuring forceful mains immunity.
The measurements are linear in the complete temperature range from 0...165°C with a resolution of 0.01°C. An
information code is recorded if the temperature is above
or below this range (see section 5).
The temperature measurements are effectuated at every
energy integration as well as every 10 sec. when the display is updated.
4. Permanent memory
The calculator’s EEPROM is updated hourly with all the
accumulated values, thus ensuring minimum loss in the
event of total power cut (concurrent failure on back-up
and primary supply). On the programmed billing date,
e.g. 1 June, all relevant data is saved with regard to annual billing reading.
Calculator features
Additionally, the EEPROM comprises an extensive data
logger with intervals from hours to years. The data logger’s capacity is 960 hours/60 days/36 months/15
years. Furthermore, all changes in the info code are
logged (see section 5), which facilitates effective trouble
shooting.
230 VAC, type 66-00-300-000
Supply module with galvanic separation from the net
supply. The module meets the demands of douple isolation and is designed for direct net connection.
NB: National installation rules and regulations must be
complied with!
5. Information codes
24 VAC/DC, type 66-00-400-000
During normal operation the information code will be
"000". If one or more of the following errors occur, the
information codes will be added together and the letter
“E” will be shown in the display. The information code
will be displayed if you activate the right key on the front
panel until the measurement unit shows “info”.
Supply module which reduces the input voltage to
approx. 3.7 VDC. The module is not galvanically isolated
and should therefore be used together with a galvanically separated transformer, e.g. type 66-99-400 (230/24 V).
When the error is corrected, the information code automatically resets after approx. 10 min. The information
codes for leakage are, however, reset at midnight,
provided that no leakages have been registered for the
past 24 hours.
The latest 10 changes in the information codes are saved
in the EEPROM, together with information on date, clock
and energy reading.
001 Failure in primary supply, battery or net supply
004 T2 temperature sensor below or above
measurement range
008 T1 temperature sensor below or above
measurement range
032 T3 temperature sensor below or above
measurement range
064 Leakage in the tap water system
256 Leakage in the heat/cooling system
512 Burst in the heat/cooling system
6. Optical reading
An optical, infra-red/transmitter is placed in the bottom
left-hand corner on the front of MULTICAL® in accordance
with EN 61 107. By means of the IR head, type 66-99102 (with 9-pole D-sub), the optical interface can be
directly connected to a hand-held terminal or a PC. Then
all data can be read and all the meter’s parameters can
be reconfigured. Calibrated parameters, e.g. pulse/l,
cannot be reprogrammed without breaking the verification seal.
The optical interface can also be used for printing from
the hourly or 24-hourly dataloggers. An optical IR head,
type 66-99-107 (with 25 pole D-sub), uses printers with
a serial interface.
7. Voltage supply
MULTICAL is constructed with two separate voltage supplies: a back-up battery, which is incorporated in the calculator top, as well as a primary supply, which is placed
in the base of the unit.
®
The primary supply is either a D-cell lithium battery or a
supply module designed for external net supply. A
change from one supply type to another can be carried
out on site without re-verification.
Battery, type 66-00-200-000
“High Capacity D-cell” lithium batteries must be used.
These are very reliable and ensure safe, reliable metering
for up to 10 years, depending on the application (see
technical data).
24 VDC with S0 input, type 66-00-500-000
Is used for combined supply and retrieval of pulses from
the electricity meter to the calculator’s input B, via an
S0-converter.
24 VDC with flow meter input,
type 66-00-600-000
Is used for combined supply and retrieval of volume
pulses from net-supplied volume meters which simultaneously supply the calculator.
8. Tariff functions
MULTICAL® type 66-C and 66-E have a number of various
tariff functions which can be used for accumulated energy under a defined condition, calculation of average
values of flow and return temperatures as well as control
of a 3-point motor-operated valve for limitation of flow
and power.

9. Plug-in modules
MULTICAL® can be extended by means of a plug-in
module as required - and without reverification. The
modular space communicates with the calculator’s
microprocessor by means of an internal databus, which
for safety reasons, is galvanically separated from the
plug-in module.
The plug-in modules now available, which are listed in
the order specification, can be supplied together with
the calculator or separately for retrofitting in meters that
are already installed.
10. Programming & verification
METERTOOL for MULTICAL® type 66-CDE is Windows®
based software, which contains all facilities necessary to
program the calculator. When the software is used with
VERIFICATION EQUIPMENT, type 66-99-28x, the calculator can be tested and calibrated. See “Accessories” for
type number of METERTOOL and VERIFICATION EQUIPMENT.
