This chapter contains application guidelines for:
▪ Setting up the space heating system
▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up the power consumption control
▪ Setting up an external temperature sensor
5.2 Setting up the space heating system
The heat pump system supplies leaving water to heat emitters in one or more
rooms.
Because the system offers a wide flexibility to control the temperature in each
room, you need to answer the following questions first:
▪ How many rooms are heated by the heat pump system?
