Explanation
External gas valve closes.
The fan runs slower, before the flue gas valve is closed.
The fan has stopped.
The power of the appliance is decreased to lower the flue gas temperature.
The auto refill device fills the installation. The installation was empty.
The auto refill device tops up the installation. The water pressure in the in­
stallation was low.
The desired flow temperature is reduced to protect the heat exchanger.
Gas valve modulator offset correction is in progress.
The pump is active after the appliance stopped in order to bring the re­
maining heat into the system.
The pump has stopped.
The external hydraulic valve closes.
Activates the duration of time between two central heating production cy­
cles.
The compressor is not authorized to start. The backup boiler or backup
electrical heater is on to meet the heat demand.
The heat pump stopped because the internal flow temperature is over the
set limit. The backup boiler or backup electrical heater is producing.
The compressor is not authorized to start because the outdoor temperature
is beyond the set limits. The backup boiler or backup electrical heater is on
to meet the heat demand.
The compressor stopped because the performance is insufficient. The
backup boiler is on.
The outdoor unit performs a defrost operation with the compressor. The
water temperatures are sufficient for operation without support from a
backup boiler or backup electrical heater.
The defrost operation stopped because the internal flow temperature is too
low. The backup boiler or backup electrical heater started in order to in­
crease the internal flow temperature.
The internal flow temperature is low from the defrost operation. The backup
boiler or backup electrical heater started to prevent a further decrease in
temperature.
Indicates the operating time of the source pump when the compressor
stops. This source pump operation is only for ground source heat pumps.
The backup boiler or backup electrical heater is still producing.
The heat pump and backup boiler or backup electrical heater stopped. The
internal flow temperature is over the set limit.
Indicates the operating time of the source pump when the compressor
stops. This source pump operation is only for ground source heat pumps.
The heat pump stopped while in cooling mode. The humidity sensor detec­
ted too much humidity from condensing.
The heat pump stopped because the water flow rate in the exchanger is
too low.
The cooling water setpoint increased to avoid condensing.
The compressor and backup boiler or backup electrical heater are not au­
thorized to start for a heat demand or domestic hot water.
The compressor is not authorized to start for a cool demand.
The compressor is not authorized to start because the outdoor temperature
is beyond the set limits.
The heat pump is off because the internal flow temperature is over the set
cooling mode limit.
The water pump is on and the diverter valve is in the heating position dur­
ing deaeration.
The water pump is on and the diverter valve is in the domestic hot water
position during deaeration.
