INSTALLATION
• Using a flat wrench (2), open the trap (1) a ¼ turn in order to
remove the air present in the glycol circuit, then close it quickly
(in order to avoid emptying the circuit).
The venting process is carried out for 15 minutes.
• Repeat this last operation at the end of the venting procedure.
• Press the button .
b The venting may result in a drop in the glycol
circuit pressure.
• Ensure that the glycol circuit pressure is between 1.5 and
2bars. If it not, top up the glycol circuit.
b When venting is complete, make sure that the
various heating circuit air vent are open.
12.8.5 Adjustment of HP circuit flow
The heat pump is designed to operate with a minimum flow of
750 l / h. If the flow is less than 500 l / h, the heat pump will stop
and the boiler will begin to function. Heating comfort will always
be guaranteed, but energy saving will be compromised.
The heat pump is equipped with a flow sensor and it is possible
to read the water flow directly via the control unit.
i
The HP circuit flow should be between 750 and 850 l / h.
i Incorrect venting of the installation may lead to
variations in flow.
• Using the buttons ,
select HP circuit flow on the screen.
• Press the button to confirm.
• Using the button , launch the
reading of the heat pump circuit flow.

1 flow control valve
• Use the control valve (1) to adjust the flow of the HP circuit to
between 750 and 850 l/h.
i
If you are unable to obtain a flow of between 750 and
850l/h using the flow control valve (1), change the
speed of the hydraulic pump module.
• Press the button to stop the flow reading via the
control unit.
• Press the button .
