Starting and stopping the heat pump
4.2.1
Starting the heat pump
1. Switch on the outdoor unit and the indoor unit.
The heat pump will begin an automatic vent cycle (which lasts
approx. three minutes), run each time the power is switched on.
2. Check the hydraulic pressure in the installation indicated on the user
interface.
Important
Recommended hydraulic pressure between 1.5 and 2.0 bar.
4.2.2
Shutting down the heat pump
The heat pump must be shut down in certain situations, for example
during any intervention on the equipment. In other situations, such as an
extended absence period, we recommend that the Holiday operating
mode is used in order to benefit from the heat pump anti-blocking function
and to protect the installation from frost.
To shut down the heat pump:
1. Switch off the power to the outdoor unit.
2. Switch off the power to the indoor unit.
4.3
Switching the central heating on/off
Your appliance will automatically deactivate the heating function and
switch to cooling mode when the temperature exceeds 22 °C (factory
setting). However, you can manually switch off the heating function for all
circuits to save energy during the summer period, for example.
