This chapter contains applications guidelines for:

▪ Setting up the space heating/cooling system

▪ Setting up an auxiliary heat source for space heating
▪ Setting up the domestic hot water tank
▪ Setting up the energy metering
▪ Setting up the power consumption
▪ Setting up an external temperature sensor
5.2 Setting up the space heating/cooling
system
The Daikin 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 (or cooled) by the Daikin heat pump
system?
