Legionella heating activated
▪ NO: A legionella heating of the DHW tank is not carried
out.
▪ YES: Once a week the DHW tank is heated to the
temperature set under the parameter “DHW tank temp.
setpoint for legionella heating (same for all DHW
tanks)”.
When should the legionella heating be carried out
Determines the day of the week on which the legionella
heating of the domestic hot water is carried out.
DHW tank temp. setpoint for legionella heating
(same for all DHW tanks)
If the parameter “Legionella heating activated” is set to
“YES”, the DHW tank is heated to the set temperature on
the specified day of the week.
Which buffer tank or heat distributor supplies the
heat to this DHW tank (0 = boiler)
Prerequisite: Parameter can only be used in conjunction
with multiple house systems (variants)
This parameter defines the allocation of the heat source
for this DHW tank.
▪ 0 = Boiler
▪ 1 = Buffer tank 01, …
DHW tanks run-on
⇒
(this setting applies for all
DHW tanks)
When DHW tank loading has finished, the DHW tank
loading pumps continue to run for the time set here.
Sensor input of DHW tank 01 … 08 top sensor
Sensor input to which the DHW tank sensor is connected.
Sensor input of DHW tank 01 … 08 solar reference
sensor
Sensor input to which the sensor for the DHW tank solar
reference is connected.
Pump output of DHW tank 01 … 08 pump
Pump outlet to which the boiler loading pump is
connected.
Control of DHW tank pump
Definition of control signal for pump type used.
Ü "Activation options of pump outlets" [}96]
Minimum DHW tank speed
Adjustment of the minimum speed to the pump type (set
mode of pump in accordance with pump manufacturer).
Maximum DHW tank pump speed
If for reasons of system operation you need to limit the
maximum speed of the DHW tank loading pump you can
do so by adjusting this parameter.
4.3 Solar
4.3.1 Solar - Status
Collector temperature
Display of the current temperature at the solar collector.
Top storage tank solar sensor
Display of the current temperature at the solar reference
sensor in the top part of the buffer tank.
Solar temperature buffer tank bottom
Display of the current temperature at the solar reference
sensor in the lower part of the buffer tank.
Collector return temperature
Prerequisite: Hydraulic system 12 or 13
Display of the current temperature at the collector return.
Actual power from solar heat meter [kW]
Display of the current output which is generated by the
solar collector. The calculation of the output is only
performed either when a per litre output of the collector
pump has been set or an external volume pulse
transmitter is used. In order to perform the calculation
more precisely, the use of a collector return sensor is
recommended.
