3066 High DHW demand recognised
3066.0 Draw-off volume threshold
If the DHW volume drawn off exceeds the set value
within the period in parameter 3066.1, the instantane-
ous heating water heater is switched on for DHW heat-
ing in addition to the heat pump.
If the DHW volume drawn off falls below the set value
again within the period in parameter 3066.1, the
instantaneous heating water heater is switched off.
Requirements:
■
Instantaneous heating water heater is enabled for
DHW heating.
■
Parameter 3029.0 set to 1.
■
The criteria for DHW heating are met.
3066.1 Time threshold
If the DHW volume drawn off exceeds the draw-off vol-
ume threshold in parameter 3066.0 within the period
set here, the instantaneous heating water heater is
switched on for DHW heating in addition to the heat
pump.
If the DHW volume drawn off falls below the draw-off
volume threshold in parameter 3066.0 again during the
period set here, the instantaneous heating water
heater is switched off.
Requirements:
■
Instantaneous heating water heater is enabled for
DHW heating.
■
Parameter 3029.0 set to 1.
■
The criteria for DHW heating are met.
3068 Set DHW temperature for target temperature control
3068.0 Set DHW temperature for target temperature control
Set DHW temperature for DHW heating with loading
cylinder in comfort mode: See parameter 3029.0.
