•
protect the evaporator from frosting; if in summertime the heat pump cannot operate due
to a low room temperature, the EH switches on,
•
alternative source; in case of a failure of the heat pump unit.
Frost protection sensor
The heat pump regulator contains an air temperature sensor, which measures the temperature of the
air that flows through the evaporator. If the air temperature is below 7
°
C (factory-set), the sensor
switches off the HP for at least 30 minutes. If the heat pump has an integrated electric heater, the
heating is automatically reconnected using the electric heater (in summertime), or the circulation
pump of the connected boiler is switched on (in wintertime).
Safety thermostat of the electric heater
The electric heater has an integrated working and safety thermostat limited to 65 °C. The safety
thermostat switches off at 85 °C and must then be reset manually.
The safety thermostat is below the flavge cover
Unplug the heat pump from the power supply:
•
Remove the flange cover.
•
Press the red button on the safety
thermostat until you heat a „Click“.
•
Mount the flange cover.
Control of the water temperature in the water heater
The OPTITRONIC regulation is used to monitor the heating of water to the set temperature.
Depending on the set water temperature, the regulation starts or stops the operation of the
compressor and the fan and under certain conditions it also switches on and off the electric heater or
the boiler circulation pump. The maximum set heating temperature is 55
°
C when operating with the
compressor. When using the “HT” key for fast heating, the temperature reaches 60
°
C.
High pressure control
A high-pressure safety switch is installed to prevent the occurrence of high pressure in the
refrigerant circuit and possible damages. In the event of an increased pressure, the heat pump
operation is switched off, thus preventing damage to the compressor. If he pressure in the system
drops, the heat pump automatically switches back on. In this, case error »E7« appears on the display.
Operating conditions
In normal operation, the ambient temperature should be between -7
°
C and +35
°
C. The air must be
clean and the relative humidity at +40
°
C should not exceed 50%. If the ambient temperature is lower,
the relative air humidity can be somewhat higher. The appliance cannot be installed at a height of
more than 2000 m above sea level, since the lower air pressure can substantially reduce the heating
capacity of the device.
