Explanation
The water pump is off and the diverter valve is in the heating position dur­
ing deaeration.
The water pump is off and the diverter valve is in the domestic hot water
position during deaeration.
When the BL input is active, the backup boiler or backup electrical heater is
not authorized to start for a heat demand.
When the BL input is active, the compressor is not authorized to start for a
heat or cool demand.
When the BL input is active, the compressor and backup boiler or backup
electrical heater are not authorized to start for a heat demand.
When the BL input is active, the low tariff period is active.
When the BL input is active, only the compressor is authorized to start
when photovoltaic energy is available.
When the BL input is active, the compressor and backup boiler or backup
electrical heater are authorized to start when photovoltaic energy is availa­
ble.
When the BL input is active, the Smart grid control logic is active.
The boiler is in wait state until the water pressure is sufficient. The deaera­
tion program will not start.
Heating power is not available in the system.
The gas valve modulator cannot compensate for the high caloric gas quali­
ty. Minimum power is increased for one hour to keep the burner operating.
The modulation range of the boiler is limited during this mode.
The gas valve modulator cannot compensate for the low caloric gas quali­
ty. Maximum power is decreased to keep the burner operating. The modu­
lation range of the boiler is limited during this mode.
The heat pump operates in free cooling mode while the central heating wa­
ter pump is off.
The heat pump operates in free cooling mode while the central heating wa­
ter pump is on.
The source pump turns on before the compressor starts. This source pump
operation is only for ground source heat pumps.
The electronic combustion process calibrates the combustion.
The block input function is enabled.
After the heat demand, the compressor will start up (ON, but not allowed to
go OFF) for a certain time.
Evaporator curative defrosting is active. The heating gas valve (HGV) is
opened to diverte all energy from the compressor to the evaprorator to re­
move the ice.
Evaporator preventive defrosting is active. The heating gas valve (HGV)
will open and close to distribute the compressor energy in a given cycle be­
tween the DHW tank and the evaporator to prevent icing.
Initialisation is finished.
The CSU is initialising.
The identifiers are initialising.
The blocking parameters are initialising.
The safety unit is initialising.
The blocking is initialising.
The sub state is undefined.
The safety unit is blocking due to too many resets. Wait for 60 minutes or
turn the power off and on again.
