Solar system
▪ 1: The solar panel system supplies only the DHW tank
▪ 2: The solar panel system supplies only the buffer tank
▪ 3: The solar panel system is expanded with a switch
valve and is used to supply two different heat sinks. For
example: Switch from domestic hot water tank to buffer
tank, or between top and bottom solar coils with the
hygienic solar layered tank or modular solar layered
tank with 2 solar coils)
NOTICE!This parameter is not displayed when
hydraulic system 12 or 13 is set.
Pump output of collector pump
Pump outlet to which the collector pump is connected.
Control of the collector pump
Definition of control signal for pump type used.
Ü "Activation options of pump outlets" [}96]
Minimum collector pump speed
Adjustment of the minimum speed to the pump type (set
mode of pump in accordance with pump manufacturer).
Maximum collector pump speed
If for systemic reasons you need to limit the maximum
speed of the collector pump you can do so by adjusting
this parameter.
Collector monitoring
▪ YES: The collector pump is switched on at regular
intervals for 10 seconds. The time can be defined using
the following parameter. If the collector sensor detects
an increase in temperature, the pump remains
activated continuously. This function is active from
8:00am - 7:00pm and the threshold value of the
collector temperature, from which this function is active,
is dynamically adjusted.
▪ NO: The collector pump starts only when the criterion
which is defined under parameter “Temp differential to
start collector pump” is reached.
Collector monitoring every
If the collector pump is not active within the time window
between 8:00am – 7:00pm, the pump is activated for 10
seconds at the end of the specified time set. If the
collector sensor detects an increase in temperature, the
pump remains activated continuously. If no temperature
increase on the collector sensor is detected, the collector
pump switches off and the time restarts from zero.
DHW tank priority for solar loading
▪ YES: The DHW tank is loaded until the temperature set
under „Set DHW temperature for solar charging“ is
reached.. Only then does it switch to the buffer tank by
means of the switch valve.
▪ NO: The DHW tank is loaded until the temperature
difference between the sensor on the solar collector
and the solar reference sensor in DHW tank is no
longer sufficient. The switch valve then switches to the
buffer tank and supplies it for 20 minutes. Afterwards
the collector pump is stopped for 20 minutes and a
check is carried out to see if the temperature difference
is now sufficient for DHW tank charging.
Solar charging to which buffer tank
This parameter defines the buffer tank to which the solar
charging takes place.
Solar charging to which DHW tank
This parameter defines the DHW tank to which the solar
charging takes place.
Sensor input of solar collector sensor
Sensor input to which the collector sensor is connected.
Sensor input of solar reference buffer tank top
sensor
Prerequisite: Hydraulic system 12 or 13
Sensor input to which the solar reference sensor in the top
part of the buffer tank is connected.
Sensor input of solar reference buffer tank bottom
sensor
Sensor input to which the solar reference sensor in the
lower part of the buffer tank is connected.
Sensor input of secondary HE sensor flow
Prerequisite: Hydraulic system 12 or 13
Sensor input to which the sensor at heat exchanger flow
on the secondary side is connected.
Sensor input of the collector return sensor
Sensor input to which the sensor for the collector return is
connected.
Pump output of the solar isolating valve
Pump outlet to which the solar isolating valve is
connected.
