3.2. Scope of this manual

This manual does NOT include the selection procedure and the water
system design procedure. Only some precautions and tips and tricks
about the design of the water circuit are given in a separate chapter
of this manual.
Once the selection is done and the water system is designed, this
manual describes the procedures for handling, installing and
connecting the RKHBH/X units. This manual has been prepared to
ensure adequate maintenance of the unit, and it will provide help if
problems occur.

Pump operation and space heating
When the room thermostat (T) is connected to the indoor unit, the
pump (5) will operate when there is a heating request from the room
thermostat, and the outdoor unit will start operating to achieve the
target leaving water temperature as set on the user interface.
When the room temperature is above the thermostat set point, the
outdoor unit and pump will stop operating.
NOTICE
Make sure to connect the thermostat wires to the correct
terminals (see "Connection of the thermostat cable" on
page 20) and to configure the DIP switch toggle switches
correctly (see "8.2. Room
