Heating medium
Hot liquid, usually normal water, which is sent from the heat pump to the
house climate system and makes the accommodation warm. The heating
medium also heats the hot water through the double jacketed tank or coil
tank.
Heating medium side
Pipes to the house’s climate system and condenser make up the heating
medium side.
Mixing valve
A valve that mixes the cold water with the hot water leaving the heater.
Outside sensor
A sensor that is located outdoors. This sensor tells the heat pump how hot
it is outdoors.
Pressostat
Pressure switch that triggers an alarm and/or stops the compressor if non-
permitted pressures occur in the system. A high pressure pressostat trips
if the condensing pressure is too great. A low pressure pressostat trips if
the evaporation pressure is too low.
Radiator
Another word for heating element. They must be filled with water in order
to be used with SMO 20.
Return pipe
The line in which the water is transported back to the heat pump from
the house heating system (radiators/heating coils).
Return temp
The temperature of the water that returns to the heat pump after releasing
the heat energy to the radiators/heating coils.
Room sensor
A sensor that is located indoors. This sensor tells the heat pump how hot
it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
