7 Quick-start procedure
Before switching on the hydraulic unit :
• Check the electric wiring.
• Check the refrigeration circuit and make sure the gas
supply has been performed.
• Check the pressure of the hydraulic circuit (1-2 bar),
check that the heat pump is purged, and the rest of the
installation.
• Make sure that ALL DIP SW are OFF before starting
up. (figure
23 page 20
).
7 1 Start-up
-Turn ON the start/stop switch.
-Configure the hydraulic circuit (setting 5700) :
Presettings :
1. 1 heating circuit (by default).
2. 1 heating circuit and DHW tank.
3. 2 heating circuits.
4. 2 heating circuitsand DHW tank.
5. Boiler backup and 1 heating circuit.
6. Boiler backup and 2 heating circuits.
7. Boiler backup, 1 heating circuit
and DHW tank.
8. Boiler backup, 2 heating circuits
and DHW tank.
-Time, Date and time programs for HC1, HC2, DHW if
different than default values (settings 500 – 576).
-Ajust the heating curve slope (720; 1020) and curve
off-set (721; 1021).
The heat pump is ready for operation !
You can also :
1. Adjust the heating circuit setpoints if different
than default values (710 – 714; 1010-1014).
2. Adjust the DHW setpoints if different than
default values (1610-1612)
3. Start a legionella cycle (1640-1647).
4. Perform floor drying (850-857).
