Connecting the heat pump to
the power supply
Ensure the electricity has been switched off before connecting the heat
pump to the mains. Check that cables and printed circuit boards are
intact.
High and low current cables should be routed separately in order
to avoid interference on the sensors. Wiring diagram is supplied
with the heat pump.
A description of external connections is given in this section.
Examples of external connections include room and outdoor sensors and
mixing valves.
The mains connection as well as the material used to make this
connection must comply with current electrical regulations.
The heat pump electrical supply must be protected with a D curve earth
leakage circuit breaker. Wiring must be H07RNF type. Supply must be
L+N+E 230V single-phase.
Installation of sensors
Install the return sensor radiator T1 (GT1) in direct contact with the
return pipe, approximately 1-2 m from the heat pump and, if possible,
after a 90° bend.
Install the outdoor sensor T2 (GT2) on the north side of the house.
Hot water sensor T3 (GT3) must be installed if an external hot water
cylinder is used. Install the sensor approximately 1/3 of the way up from
the bottom of the cylinder. The sensor must be installed above the
connection to the heat pump.
Install the Room sensor T5 (GT5) in the center of the house. The room
sensor should not be influenced by other heat sources or direct sunlight.
Only the room where the room sensor
is located can influence regulation of
the temperature.
The electrical installation may only be
performed by a qualified electrician.
The main power supply must be
disconnected before working on the
heat pump.
