Residual heat use
Prerequisite: Hydraulic system 0 and return temperature
control with mixing valve
▪ YES: Diverts the residual heat to the DHW tank. The
“Minimum boiler temperature to release
all pumps”
parameter is ignored. The pump is set to
minimum speed until the boiler temperature is lower
than the DHW tank tempe 3°C.
Only load DHW tank once a day
▪ NO: A DHW loading takes place always when the DHW
tank temperature falls below the value, which is set
under
“Reload if DHW tank temperature is
below”
, and the time window is active and the heat
source (boiler or buffer tank) indicates sufficient
temperature.
▪ YES: If the DHW tank has already been loaded once on
the current day, a further DHW tank loading is
prevented.
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 tank pumps 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 top sensor
Sensor input to which the DHW tank sensor is connected.
Sensor input of DHW tank 01 solar reference sensor
Sensor input to which the sensor for the DHW tank solar
reference is connected.
Pump output of DHW tank 01 pump
Pump outlet to which the boiler loading pump is
connected.
Control of DHW tank pump
Definition of control signal for pump type used.
