2.7.6 Electrical installation checklist
Check the following:
1. The control cabinet’s supply input connection has the correct phase sequence.
2. The main fuse has a sufficient rating.
3. The ground source heat pump’s fuses have the correct rating and are of the right
type (slow-blow, C curve).
4. If applicable, priority relays have been installed to the building’s distribution board.
5. The heat pump’s mains cable has a sufficient capacity.
2.8 Combining several heat pumps
Master and slave operation
If the ground source heating system includes more than one ground source heat pump,
one of the heat pumps (the ‘master’) controls the rest of the heat pumps (the‘slaves’).
● Connect all of the sensors in the system to the master heat pump.
The necessary settings have been configured at the factory, and the heat pumps have
been marked with labels (MASTER and SLAVE respectively). You can use any of the
heat pumps’ controllers to control and monitor the entire system.
If the heat pump system comes with the optional compressor rotation function, you can
adjust compressor rotation settings in the Compressor rotation view (see Compressor
rotation
).
