Before switching on the control box :
• Check the electric wiring.
• Check the pressure of the hydraulic circuit (1-2 bar),
check that the heat pump is purged, and the rest of the
installation.
- Turn the start/stop switch.
- Congure the hydraulic circuit (setting 5700) :
Presettings :
1. 1 heating circuit (by default).
2. 1 heating circuit and DHW tank.
3. Boiler backup and 1 heating circuit.
4. Boiler backup, 1 heating circuit
and DHW tank.
- Time, Date and time programs for HC1, DHW if
different than default values (settings 500 – 576).
- Ajust the heating curve slope (720) and curve off-set (721).
You can also :
1. Adjust the heating circuit setpoints if different
than default values (710 – 714).
2. Adjust the DHW setpoints if different than
default values (1610-1612).
3. Start a legionella cycle (1640-1647).
4. Perform oor drying (850-857).
