PROBABLE CAUSE 3; THE UNDER FLOOR HEATING
SYSTEM OR RADIATOR VALVES ARE CLOSED:
BOpen the valves.
PROBABLE CAUSE 4; THE FLOW ACROSS THE HEAT
PUMP IS GREATER THAN THE FLOW IN THE HEATING
SYSTEM:
BContact the dealer.
8.7.2 ADD. HEAT IS NOW WORKING AT ITS HIGHEST
PERMITTED TEMPERATURE
Temperature sensor T9 is fitted inside the heat pump.
This stops the compressor for safety reasons and limits
the electric additional heater as soon as the return
temperature is too high. The limit for the electric
additional heater is approx. 58 °C.
PROBABLE CAUSE 1; THE HEAT SETTING IS SET SO
HIGH THAT THE HEATING SYSTEM’S RETURN
TEMPERATURE IS TOO HIGH:
BReduce the temperature setting.
8.7.3 THIS SETTING MEANS THAT ADDITIONAL
HEAT CAN TAKE OVER OPERATION
Information appears if Electric cassette limitation start
temperature, Electric cassette forced shut off, Mixing
valve limitation start temperature or Mixing valve force
close are set more than 1 degree lower than T9 high
return temperature.
POSSIBLE CAUSE 1: THE INSTALLER SETS A HIGH
VALUE FOR ONE OF THE ABOVE SETTINGS.
BContact the dealer.
8.7.4 TEMPORARY STOP OF HOT WATER
PRODUCTION
In case of DHW operation and if the temperature
captured ar senor T6 is higher than for envelope stop
(factory-set value: 117 °C), this message is issued until
T3 has fallen 5 K below the temperature which was
captured by T3 when the message appeared. This
message stops the compressor for DHW heating.
POSSIBLE CAUSE 1: EXCESSIVE TEMPERATURE
DIFFERENTIAL BETWEEN EVAPORATION AND
CONDENSING. THE COMPRESSOR PERMITS THE
ADDITIONAL HEATER TO SUPPLY THE CORRECT
TEMPERATURE IF IT CANNOT DO SO ON ITS OWN.
POSSIBLE CAUSE 2: LOW REFRIGERANT LEVEL.
8.7.5 TEMPORARY STOP OF COMPRESSOR
OPERATION
Could occur for two different reasons:
1. If the temperature captured by sensor T2 is lower
than the lowest temperature envelope. Switches back
when the temperature captured by sensor T2 is higher
than the lowest temperature envelope for 30 minutes.
2. In case of heating operation and if the temperature
captured by sensor T6 is higher than for envelope
stop (factory-set value: 117 °C). Switches back when
the temperature captured by sensor T2 has risen by 2
K.
The compressor stops and the additional heater starts.
POSSIBLE CAUSE 1: OUTSIDE TEMPERATURE LOWER
THAN -20 °C.
POSSIBLE CAUSE 2: EXCESSIVE TEMPERATURE
DIFFERENTIAL BETWEEN EVAPORATION AND
CONDENSING. THE COMPRESSOR PERMITS THE
ADDITIONAL HEATER TO SUPPLY THE CORRECT
TEMPERATURE IF IT CANNOT DO SO ON ITS OWN.
POSSIBLE CAUSE 3: LOW REFRIGERANT LEVEL.
