Room sensor
A sensor that is located indoors. This sensor tells the indoor module how
hot it is indoors.
Safety valve
A valve that opens and releases a small amount of liquid if the pressure is
too high.
Shunt
A valve that mixes the hot water with a small amount of slightly cooler
water. There is a shunt in the indoor module that mixes the supply water
with the return line so that the heating system r eaches the correct temper-
ature.
Shuttle valve
A valve that can send liquid in two directions. A shuttle valve that enables
liquid to be sent to the climate system, when the heat pump produces
heating for the house, and to the hot water side, when the heat pump
produces hot water.
Supply temperature
The temperature of the heated water that the indoor module sends out
to the heating system. The colder the outdoor temperature, the higher
the supply line temperature becomes.
