    The control panel is supplied inside the heat pump and must be mounted on the front of the Fusion Hybrid Oil hydraulic module. To do this, open the module door and access the control panel holder located in the rear part. For its correct assembly, please carefully follow the following steps: 1.- Open the door of the Fusion Hybrid Oil module and loosen...

  • Page 15: Configuring The Heat Pump

    To do this, pass the cable that is supplied inside the heat pump (located alongside the probe harness) to the interior of the Fusion Hybrid Oil module. The hydraulic module has a series of cable glands at the rear, through which it is possible to insert such cables into the module.

  • Page 16: Starting Up The Boiler

    Once the installation is full, close the disconnector valves. The module Fusion Hybrid Oil is equipped with a security water pressure switch set at a pressure of 0,5 bar, which does not allow the module to start until that pressure is reached in the installation.

  • Page 17: Connecting The Room Thermostat ("Auto" Mode)

    5.5 Connecting the room thermostat (“AUTO” mode) The Fusion Hybrid Oil module is prepared for the connection of up to 2 room programmable “Connection Diagram” thermostats or room thermostats (see ), which will activate or stop the heating and/or cooling service of the heating/air-conditioning installation, turning off the heat pump and the supporting module when the desired temperature is reached in the home and turning it on when it comes down again.
