Blocking of heat pump/electric heating until the flow rate is back within valid limits
-
ODU defrost function
Heating of DHW cylinder to 65 °C
DHW heating with cylinder; cylinder sensor temperature below set value
Heat generator switched OFF; ZHP runs on
At least one heating circuit is demanding heat
Heat generator switched OFF; ZHP runs on
Cooling mode active
Cascade module in system active
Heat pump is controlled by building management system
No heating or DHW demand
Refrigerant circuit drain function
Meaning
There is a fault in the heat pump/electric heater
Heat pump/electric heater/additional heat generator was deactivated via contractor parameter
No demand
Sensors are brought to same temperature level without heat generator.
Flow sensor is exposed to flow.
Heat pump in control mode
Heat pump in defrost mode
Feed/heating circuit pump (ZHP) runs on without heat generator
A blocking time is present for the heat pump
The heat pump is blocked by the power supply utility/via power supply utility contact
Heat generator in shutdown due to outside temperature
Heat generator in shutdown as maximum flow/return temperature exceeded
(application limit reached)
Heat pump in cooling mode
Supply air temperature is below the minimum level
Dew point monitor or maximum thermostat triggered
