6.1.12 External heat source (EHS)
This function is used to connect additional heat sources to the heating circuit,
e.g. water-jacketed stove, solar heat.
The heat from the external heat source is diverted into the system when the set
temperature in the external tank is reached and is at least 5°C higher than the
setpoint. Diversion stops when the temperature is 3°C higher. The compressor
and electric heater stay idle for as long as there is suffi cient energy in the
external heat source. Heat is diverted to both the heating circuit and to hot
water.
This comes to an end when one of the following alarms occur: Supply sensor 1,
HPin sensor, Communication fault. HP or if the supply sensor 1 is warmer than
80 ºC.
Enter settings under Settings/External heat source.
NB: When an external heat source is connected to the heat pump, a magnetic
fi lter should be fi tted on the return fl ow between EHS and the heat pump to
protect the heat exchanger.
The mixing valve motor ARA 671 is mounted on the
valve with the knob in the centre position. The motor
must move in an anticlockwise direction to close.
