Connecting the device to the mains supply must always be
the last step of the installation!
The power supply to the controller must be carried out via
an external power switch (last step!). The supply voltage
must be 100 ... 240 V~ (50 ... 60 Hz). Flexible cables must
be attached to the housing with the enclosed strain relief
and the corresponding screws.
The controller is equipped with two semiconductor relays, to which loads such as pumps, valves etc. can be
connected:
•• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground conductor
•• Relay 2
16 = conductor R2
15 = neutral conductor N
14 = ground conductor
The mains supply is to be carried out at the terminals:
19 = neutral conductor N
20 = conductor L
12 = ground terminal
The temperature sensors (S1 up to S4) are to be
connected to the following terminals with either polarity:

The difference between FKP and FRP type sensors only
lies in the cable insulation material. The insulation material
of FKP type sensor cables resists a higher temperature, so
that FKP type sensors should be used as collector sensors.
FRP type sensors are best used as reference sensors in
stores or pipes.
The controller is equipped with a RESOL VBus® for data
transfer with and energy supply to external modules. The
connection is carried out at the terminals marked “VBus”
(either polarity). One or more RESOL VBus® modules can
be connected via this data bus, such as
•• GA3 large display, SD3 smart display
•• DL2 datalogger
•• VBus® /USB or VBus® /LAN interface adapter
•• VBus® /PWM interface adapter
•• AM1 alarm module
•• WMZ calorimeter module
By means of a DL2 datalogger or an interface adapter, the
controller can be connected to a PC or a computer network. With the RESOL ServiceCenter Software (RSC) the
controller measurements can be read out, processed and
visualised. The software allows easy function control of the
system. For the remote parametrisation of the controller, a
special software tool will be available for download, soon.

1.4Terminal allocation in the different system layouts
System layout 1
The controller calculates the temperature difference
between collector sensor S1 and store sensor S2. If the
difference is larger than or identical to the adjusted switchon temperature difference (DT O), the solar pump will be
operated by relay 1, and the store will be loaded until the
switch-off temperature difference (DT F) or the maximum
store temperature (S MX) is reached.
Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can optionally be used as reference
sensor for the store emergency shutdown option (OSEM).
If heat quantity measurement (OHQM) is activated, sensor
S4 has to be connected as return sensor.
If the drainback option (ODB) is activated, relay 2 can be
used to operate a booster pump by activating the booster
function (OBST).

System-specific functions
The following adjustments are used for the specific function
in system layout 2.
∆T control for the heat exchange between 2 stores
DT3O:
Switch-on temperature diff.
Adjustment range:
1.0 ... 20.0 K [2.0 ... 40.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
6.0 K [12.0°Ra]
DT3F:
Switch-off temperature ­diff.
Adjustment range:
0.5 ... 19.5 K [1.0 ... 39.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
4.0 K [8.0°Ra]
Pump speed control
DT3S:
Nominal temperature difference
Adjustment range:
1.5 ... 30.0 K [3.0 ... 60.0 °Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
10.0 K [20.0 °Ra]
RIS3:
Rise
Adjustment range:
1 ... 20 K[2 ... 40 °Ra]
in steps of 1 K [2 °Ra]
Factory setting: 2 K [4 °Ra]
Reference sensors for this function are S3 and S4.
In system layout 2 the controller is equipped with an additional differential control for heat exchange between two
stores. The basic differential function is adjusted using the
switch-on (DT3O) and switch-off (DT3F) temperature
differences.
When the temperature difference exceeds the switch-on
temperature difference, relay 2 switches on. If the temperature difference then falls below the adjusted switch-off
temperature difference, relay 2 switches off.
Note:
The switch-on temperature difference must be
at least 0.5 K [1 °Ra] higher than the switch-off
tempe­rature ­difference.
Note:
For pump speed control of the heat exchange
pump, the operation mode of relay 2 (MAN2)
must be set to Auto.
When the switch-on temperature difference is reached, the
pump is activated at full speed for 10 seconds.Then, the speed
is reduced to the minimum pump speed value (n2MN).
If the temperature difference reaches the adjusted nominal
temperature difference (DT3S), the pump speed increases by
one step (10 %). If the difference increases by the adjustable rise
value, the pump speed increases by 10 % respectively until the
maximum pump speed of 100 % is reached.The response of
the controller can be adapted via the parameter RIS3.
Note:
The nominal temperature difference must be
at least 0.5 K [1 °Ra] higher than the switch-on
tempe­rature ­difference.
Minimum pump speed

A relative minimum pump speed can be allocated to the
output R2 via the adjustment channel n2MN.
Note:
When loads which are not speed-controlled (e.g.
valves) are used, the value must be set to 100 % in
order to deactivate pump speed control.

Minimum and maximum temperature limits can be set for
the heat exchange function.
The maximum temperature limitation uses sensor 4 as
reference sensor.
The maximum temperature limitation function provides
a maximum tem­perature setting, usually to reduce scald
risk in a storage store. If MX3O is exceeded, relay 2 is
switched off until the temperature at sensor 4 falls below
MX3F.
The minimum temperature limitation uses sensor 3 as
reference sensor.
The minimum temperature limitation function provides
a minimum tem­perature setting for the heat source in
system layout 2. If the temperature at sensor 3 falls below
MN3O, relay 2 is switched off until the temperature at
sensor 3 exceeds MN3F.
© RESOL 11157_deltasol_bs_plus.monen.indd
Both switch-on and switch-off temperature differences
DT3O and DT3F are valid for the maximum and minimum
temperature limitation.

System layout 3
The controller calculates the temperature difference
between collector sensor S1 and store sensor S2. If the
difference is larger than or identical to the adjusted switchon temperature difference (DT O), the solar pump will be
operated by relay 1, and the store will be loaded until the
switch-off temperature difference (DT F) or the maximum
store temperature (S MX) is reached.
Sensor S3 is used for a thermostatic function, which operates relay 2 for afterheating or heat dump purposes, when
the adjusted thermostat switch-on temperature (AH O) is
reached. This function can optionally be combined with up
to three adjustable time frames.
Sensor S3 can also be optionally used as a reference sensor
for the thermal disinfection function OTD or the store
emergency shutdown option (OSEM).
Sensor S4 can optionally be connected for measurement
purposes. If heat quantity measurement (OHQM) is activated, sensor S4 has to be connected as return sensor.

This function is used for protecting the upper store zone
against Legionella by activating the afterheating.
Reference sensor for the thermal disinfection is S3!
ÎÎ To activate the function, select “On” in the OTD
channel.
For thermal disinfection, the temperature in the upper
DHW store zone has to be monitored. This protection is
ensured when, during the monitoring period (PDIS), the
disinfection temperature (TDIS) is continuously exceeded
for the entire heating period (DDIS). S3 is used as the
reference sensor and displayed as TSTT.
If OTD is activated, PDIS will start as soon as the temperature at S3 falls below TDIS. The display channel CDIS
appears, counting backwards the remaining time of PDIS.
If, during the monitoring period, the temperature at S3
exceeds TDIS continuously for the duration of DDIS,
thermal disinfection is considered complete and a new
monitoring period begins.
If CDIS counts down to 00:00, relay 2 will be operated
in order to use the afterheating for thermal disinfection.
CDIS will then be replaced with a display channel DDIS
showing the adjusted heating period. DDIS will start counting down the heating period as soon as TDIS is exceeded
at S3. As long as DDIS is active, the temperature at S3 will
be displayed as TDIS instead of TSTT.
If, during DDIS, the temperature at S3 exceeds TDIS by
more than 5 K [10 °Ra], relay 2 is switched off until the
temperature falls below TDIS + 2 K [4 °Ra].
If, during DDIS, the temperature at S3 falls below TDIS,
the heating period will restart. DDIS can only be completed when TDIS is exceeded without interruption.
Due to the flexible control logic, the exact time of thermal
disinfection is not predictable. In order to set a fixed time
for the disinfection to be run, the starting delay SDIS must
be employed:
© RESOL 11157_deltasol_bs_plus.monen.indd
Thermal disinfection with starting delay
SDIS
Starting time
Adjustment range:
00:00 ... 24:00 (o´clock)
in steps of: 00:01
Factory setting: 00:00
When a starting time for thermal disinfection with starting
delay is adjusted in SDIS, the thermal disinfection will be
delayed until that time, even after the CDIS has counted
down to 00:00. If CDIS ends, for example, at 12:00 o‘clock,
and SDIS has been set to 18:30, relay 2 will be operated
with a delay of 6.5 hours at 18:30 instead of 12:00.
During the waiting time, SDIS is displayed with the adjusted
starting time (flashing).
If, during the waiting time, the temperature at S3 exceeds
TDIS for the adjusted heating period DDIS, thermal
disinfection is considered complete and a new monitoring
period begins.
If the starting time is adjusted to 00:00 (factory setting), the
delay function is inactive.
Upon delivery, OTD is deactivated. The adjustment values
PDIS, TDIS, DDIS and SDIS are displayed after the
option has been activated. After the thermal disinfection
function has been completed, the values will be “hidden”
and the monitoring period will be displayed.

The controller calculates the temperature differences between collector sensor S1 and store sensors S2 and S3. If
the differences are larger than or identical to the adjusted
switch-on temperature differences (DT1O / DT2O), the
solar pump will be operated by relay 1, and the respective
store zone will be loaded until the switch-off temperature
differences (DT1F / DT2F) or the maximum store tempera-
tures (S1MX / S2MX) are reached.The priority logic causes
priority loading of the upper zone of the store, if possible.
The 3-way-valve will be operated by relay 2 then.
Sensor S4 can optionally be connected for measurement
purposes.
If heat quantity measurement (OHQM) is activated, sensor
S4 has to be connected as return sensor.

The controller calculates the temperature differences between collector sensor S1 and store sensors S2 and S3. If
the differences are larger than or identical to the adjusted
switch-on temperature differences (DT1O / DT2O), the
solar pumps will be operated by relay 1 and / or relay 2,
and the respective store will be loaded until the switch-off
temperature differences (DT1F / DT2F) or the maximum
store temperatures (S1MX / S2MX) are reached.The priority logic causes priority loading of the selected store (PRIO),

System-specific functions
The following adjustments are used for the specific functions
in system layout 8.
∆T control for afterheating by solid fuel boiler
Reference sensors for this function are S4 and S3.
In system layout 8, the controller is equipped with an additional differential control for heat exchange from a solid
fuel boiler (e.g. woodstove). The basic differential function
is adjusted using the switch-on (DT3O) and switch-off
(DT3F) temperature differences.
When the switch-on difference is reached, relay 2 switches on. When the temperature difference falls below
the adjusted switch-off temperature difference, relay 2
switches off.
DT3F:
Switch-off temperature ­diff.
Adjustment range:
0.5 ... 19.5 K [1.0 ... 39.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
4.0 K [8.0°Ra]
Pump speed control
DT3S:
Nominal temperature difference
Adjustment range:
1.5 ... 30.0 K [3.0 ... 60.0 °Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
10.0 K [20.0 °Ra]
RIS3:
Rise
Adjustment range:
1 ... 20 K [2 ... 40 °Ra]
in steps of 1 K [2 °Ra]
Factory setting: 2 K [4 °Ra]
Minimum pump speed
n2MN:
Pump speed control
Adjustment range: 30 ... 100
in steps of 5 %
Factory setting: 30
| 26
Note:
The switch-on temperature difference must be
at least 0.5 K [1 °Ra] higher than the switch-off
tempe­rature ­difference.
Note:
For pump speed control of the solid fuel boiler
pump, the operation mode of relay 2 (MAN2)
must be set to Auto.
When the switch-on temperature difference is reached, the
pump is activated at full speed for 10 seconds.Then, the speed
is reduced to the minimum pump speed value (n2MN).
If the temperature difference reaches the adjusted nominal
temperature difference (DT3S), the pump speed increases by
one step (10 %). If the difference increases by the adjustable rise
value, the pump speed increases by 10 % respectively until the
maximum pump speed of 100 % is reached.The response of
the controller can be adapted via the parameter RIS3.
Note:
The nominal temperature difference must be
at least 0.5 K [1 °Ra] higher than the switch-on
tempe­rature ­difference.
A relative minimum pump speed can be allocated to the
output R2 via the adjustment channel n2MN.
Note:
When loads which are not speed-controlled (e.g.
valves) are used, the value must be set to 100 % in
order to deactivate pump speed control.
© RESOL 11157_deltasol_bs_plus.monen.indd
DT3O:
Switch-on temperature diff.
Adjustment range:
1.0 ... 20.0 K [2.0 ... 40.0°Ra]
in steps of 0.5 K [1 °Ra]
Factory setting:
6.0 K [12.0°Ra]

Maximum temperature limitation
MX3O / MX3F:
Maximum temperature limitation
Adjustment range:
0.0 ... 95.0 °C [30.0 ... 200.0 °F]
in steps of 0.5 °C [1 °F]
Factory setting:
MX3O: 60.0 °C [140.0 °F]
MX3F: 58.0 °C [136.0 °F]
Minimum temperature limitation
MN3O / MN3F:
Minimum temperature limitation
Adjustment range:
0.0 ... 90.0 °C [30.0 ...190.0 °F]
in steps of 0.5 °C [1 °F]
Factory setting (Arr = 8 only):
MN3O: 60.0 °C [140.0 °F]
MN3F: 65.0 °C [150.0 °F]
Minimum and maximum temperature limits can be set for
the solid fuel boiler.
The maximum temperature limitation function provides a
maximum tem­perature setting, usually to reduce scald risk
in a storage store. If MX3O is exceeded, relay 2 is switched off until the sensor falls below MX3F. TIn Arr 8, this
function uses sensor 3 as reference sensor.
The minimum temperature limitation uses sensor 4 as
reference sensor.
The minimum temperature limitation function provides a
minimum tem­perature setting for the solid fuel boiler in
system layout 8. If the temperature at sensor 4 falls below
MN3O, relay 2 is switched off until the temperature exceeds MN3F again.
© RESOL 11157_deltasol_bs_plus.monen.indd
Both switch-on and switch-off temperature differences
DT3O and DT3F are valid for the maximum and minimum
temperature limitation.

System layout 9
The controller calculates the temperature difference
between collector sensor S1 and store sensor S2. If the
difference is larger than or identical to the adjusted switchon temperature difference (DT O), the solar pump will be
operated by relay 1, and the store will be loaded until the
switch-off temperature difference (DT F) or the maximum
store temperature (S MX) is reached.
A heating circuit return preheating will be operated by
relay 2, if the temperature difference between sensors S3
and S4 is larger than or identical to the adjusted switch-on
temperature difference (DT3O). For this purpose, relay 2
will operate the 3-way-valve. S3 can optionally be used as
reference sensor for the store emergency shutdown option
(OSEM).

The controller calculates the temperature difference
between collector sensor S1 and store sensor S2. If the
difference is larger than or identical to the adjusted switchon temperature difference (DT O), the solar pump will be
operated by relay 1, and the store will be loaded until the
switch-off temperature difference (DT F) or the maximum
store temperature (S MX) is reached.
If the maximum collector temperature (CMX) is reached, the
solar pump will be operated by relay 1 and the 3-way-valve
will be operated by relay 2 in order to direct the surplus
energy to a heat dump. For security purpose this will be
carried out only if the store temperature is below the nonadjustable emergency shutdown of 95 °C [200 °F].
Sensors S3 and S4 can optionally be connected for measurement purposes. S3 can optionally be used as reference
sensor for the store emergency shutdown option (OSEM).
If heat quantity measurement (OHQM) is activated, sensor
S4 has to be connected as return sensor.

The controller works as a standard differential controller. If
the switch-on difference is reached, the pump is activated.
When the temperature difference falls below the adjusted
switch-off temperature difference, the respective relay
switches off.
When the switch-on temperature difference is reached,
the pump is activated at full speed for 10 seconds.Then, the
speed is reduced to the minimum pump speed value (factory
setting = 30 %).
If the temperature difference reaches the adjusted nominal
temperature difference, the pump speed increases by one
step (10 %). If the difference increases by the adjustable rise
value, the pump speed increases by 10 % respectively until the
maximum pump speed of 100 % is reached.The response of
the controller can be adapted via the parameter “Rise”.

The nominal temperature difference must be
at least 0.5 K [1 °Ra] higher than the switch-on

Once the adjusted maximum temperature is exceeded,
the solar pump is switched off and further loading of the
store is prevented to reduce scald risk or system damage.
A fixed hysteresis of 2 K [4 °Ra] is set for the maximum
store temperature.
When the temperature at the corresponding sensor exceeds
the adjusted maximum store temperature, the symbol is

Cooling functions
In the following the three cooling functions – collector
cooling, system cooling and store cooling – are described
in detail. The following notes are valid for all three cooling
functions:
Note:
The cooling functions will not become active as
long as solar loading is possible.
Note:
In 2-store-systems, the cooling functions will only
affect store 1, respectively the base area of the
store (such as in Arr = 4).

Adjustment range:
70 ... 160 °C
[150 ...320 °F]
in steps of 1 °C [1 °F]
Factory setting:
110 °C [230 °F]
When the collector cooling function is activated, the controller
aims to keep the collector at an operational temperature.
When the adjusted maximum store temperature is reached,
solar loading stops. If the collector temperature increases
to the adjusted maximum collector temperature, the solar
pump is activated until the collector temperature falls at least
5 K [10 °Ra] below the maximum collector temperature.The
store temperature may increase (subordinate active maximum
store temperature), but only up to 95 °C [200°F] (emergency
shutdown of the store).
If the collector cooling function is active, and
(flashing)
is shown on the display.
Note:
This function will only be available if the system
cooling function (OSYC) is deactivated.
Note:
In system layout 10, the parameter CMX is
available without the OCC function. In system
layout 10, CMX is used to set the activation
temperature for the heat dump function. No
other switch-on condition is needed in that case.

When the system cooling function is activated, the controller aims to keep the solar system operational for a longer
time. The function overrides the maximum store temperature to provide thermal relief of the collector field and the
heat transfer fluid on hot days.
If the store temperature is higher than the maximum store
temperature (S MX / S1MX) and the switch-on temperature difference DTCO is reached, the solar system remains
activated. Solar loading is continued until either the store
temperature reaches 95 °C [200 °F] (emergency shutdown
of the store), the temperature difference falls below the
adjusted value DTCF or the collector emergency shutdown
temperature EM is reached.
If the system cooling function is active, and

When the store cooling function is activated, the controller
aims to cool down the store during the night in order to
prepare it for solar loading on the following day.
If the adjusted maximum store temperature (S MX / S1MX)
is exceeded and the collector temperature falls below the
store temperature, the system will be reactivated in order
to cool down the store. Cooling will continue until the store
temperature has fallen below the adjusted maximum store
temperature (S MX / S1MX) again.A fixed hysteresis of 2 K
[4 °Ra] is set for this function.
Reference threshold temperature differences for the store
cooling function are DT O and DT F.
If no DHW consumption is expected for a longer period
of time, the additional holiday cooling option OHOL can
be activated in order to extend the store cooling function.
The adjustable temperature THOL then replaces the
maximum store temperature (S MX / S1MX) as a switch-off
temperature for the store cooling function.
When the holiday cooling function is activated,

If the collector minimum limitation option is activated,
the pump (R1 / R2) is only switched on if the adjustable
collector minimum temperature is exceeded.The minimum
temperature prevents the pump from being switched on
too often at low collector temperatures. A fixed hysteresis
of 5 °K [10 °Ra] is set for this function
If the collector minimum limitation is active,

shown on the display.
Note:
If OSTC or OCF is active, the collector minimum
function will be overridden. In that case, the
collector temperature may fall below CMN.
The antifreeze function activates the loading circuit between
the collector and the store when the temperature falls below
the adjusted antifreeze temperature. This will protect the
fluid against freezing or coagulating. If the adjusted antifreeze
temperature is exceeded by 1 K [2 °Ra], the loading circuit
will be deactivated.

Note:
Since this function uses the limited heat quantity

used in regions with few days of temperatures
around the freezing point.
The antifreeze function will be suppressed if the
store temperature falls below 5 °C [40 °F] in
order to protect the store from frost damage.

Note:
If the priority is set to Su 1 or Su 2, solar
loading of the subordinate store will be aborted
at once if the temperature in the priority store
(store 1 for Su 1, store 2 for Su 2) falls below
the adjusted maximum temperature. If, in that
case, the temperature difference between

tRUN:
Loading runtime
Adjustment range: 1 ... 30 min
Factory setting: 15 min
If a multi-store system layout has been chosen, the priority logic determines how the heat is divided between
the stores. Different types of priority logic are adjustable:
•• spreaded loading (SE 1 and SE 2)
•• successive loading (Su 1 and Su 2)
•• parallel loading (0)
•• store sequence control (1 and 2)
If priority SE 1 or SE 2 (only available in Arr 6) is
adjusted, the subordinate store will be loaded in parallel if
the temperature difference between the collector and the
priority store (store 1 for SE 1, store 2 for SE 2) exceeds
the adjusted value DTSE and the subordinate store has not
reached its maximum temperature.
Parallel loading will stop as soon as the temperature
difference between the collector and the priority store falls
2 K [4 °Ra] below DTSE or the subordinate store reaches
its maximum temperature.
If priority Su 1 or Su 2 is adjusted, the stores are loaded
successively.The subordinate store will only be loaded if the
priority store (store 1 for Su 1, store 2 for Su 2) has reached
its adjusted maximum temperature (S1MX or S2MX).
If priority 0 is adjusted and the switch-on conditions are
fulfilled for both stores, the stores are loaded in parallel
(Arr 6), resp. in an oscillating loading (Arr 4, 5) beginning
with the store with the lowest temperature. In an oscillating
loading, solar loading will switch from one store to the other
in steps of 5 K [10 °Ra] temperature difference between
the stores.
If priority 1 / 2 is adjusted, store sequence control will
be activated (see below) with the corresponding store as
priority store.
Store sequence control will be activated when PRIO is set
to SE 1, SE 2, 1 or 2.
If the priority store cannot be loaded, the subordinate
store is checked. If useful heat can be added, it will be
loaded for the “loading runtime time” (tRUN - factory
setting 15 min.) After this, the loading process stops and
the controller monitors the increase in collector temperature during the loading break time tLB. If it increases by
2 K [4° Ra], the break time timer starts again to allow the
collector to gain more heat. If the collector temperature
does not increase sufficiently, the subordinate store will
be loaded again for the tRUN time as before.
As soon as the switch-on condition of the priority store is
fulfilled, it will be loaded. If the switch-on condition of the
priority store is not fulfilled, loading of the second store will
be continued. If the priority store reaches its maximum temperature, sequence controlled loading will not be carried out.
If store sequence control is active and the system switches
to load the priority store, the parameter tLB also acts as a
stabilisation timer, during which the switch-off condition DT F
is ignored while the system operation stabilises.

Heat quantity measurement
This function helps overcome the disadvantages caused by
the non-ideal sensor position with some tube collectors.
This function operates within an adjusted time frame (beginning at TCST and ending at TCEN). It activates the
collector circuit pump for an adjustable runtime (TCRU)
between adjustable standstill intervals (TCIN) in order to
compensate for the delayed temperature measurement.
If the runtime TCRU is set to more than ten seconds, the
pump will be run at 100 % for the first ten seconds of the
runtime. For the remaining runtime, the pump will be run
at the adjusted minimum speed nMN.
If the collector sensor is defective or the collector is blocked,
this function is suppressed or switched off.
In system layout 7 (Arr = 7) both collectors are operated
independently from each other by means of this function.
If the store is being loaded by one collector, the other one
is nevertheless operated after the adjusted standstill time.
Note:
If the drainback option ODB is activated, TCRU
will not be available. In that case, the runtime is
determined by the parameters tFLL and tSTB.
WARNING!
Danger of injury and system damage through pressure surges!
If a drainback system is filled due to
the tube collector function and the
heat transfer medium enters very hot
collectors, pressure surges can occur.
ÎÎ If a pressure-less drainback
­s ystem is used, TCST and
TCEN must be adjusted such
that the system will not be
filled during times of potentially strong irradiation!

A drainback system permits the heat transfer fluid to drain
back into the holding tank when solar energy is not collected. The drainback option will initiate the filling of the
system when solar loading begins.
If the drainback option ODB is activated, the pump will
operate at 100 % speed for the adjusted filling time tFLL
in order to fill the system with fluid from the holding tank.
After tFLL, pump speed will go down to the adjusted
minimum pump speed nMn. The switch-off conditions will
then be ignored for the stabilisation time tSTB in order to
avoid the system from shutting down prematurely.
If the function is activated, the menu items described in the
following (tDTO, tFLL and tSTB) have to be adjusted:
Note:
When the drainback option ODB is activated,
the temperature differences DT O, DT F and
DT S as well as the minimum speed values
nMN / n1MN are set to a fixed adjustment.
Additionally, the adjustment range and the
factory setting of the collector emergency
shutdown temperature EM changes (see the
corresponding channel descriptions for further
information).
Previous adjustments made in these channels will
be overridden and have to be entered again if
ODB is deactivated later on.
The parameter tDTO is used for adjusting the time period
during which the switch-on condition DT O must be permanentely fulfilled.
The filling time can be adjusted using the parameter tFLL.
During this period, the pump runs at 100 % speed.
The parameter tSTB is used for adjusting the time period
during which the switch-off condition DT F will be ignored
after the filling time has ended.
This function is used for switching on a second pump when
filling the solar system. When solar loading starts, R2 is energised in parallel to R1. After the filling time (tFLL) has ended,
R2 is switched off.
Note:
The booster function is available in system layout 1
(Arr = 1) only.
The booster function will only be available if the
drainback option has been activated.

VBus® of the controller and issues an optical signal via a red LED if a failure has occurred.
The AM1 also has a potential-free relay output, which can e. g. be connected to a building
management system (BMS). Thus, a collective error message can be issued in the case of a
system failure.
