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.
Passive cooling
See "Free cooling".
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 F1126.
Refrigerant
Substance that circulates around a closed circuit in the heat pump and that,
through pressure changes, evaporates and condenses. During evaporation,
the refrigerant absorbs heating energy and during condensing, gives off
heating energy.
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.
