Hydraulic connections
The connection must comply with good trade practice
according to local building regulations.
The appliance must be connected to the installation
with union connectors and shut-o valves to facilitate
its removal.
Reminder: Seal everything when tting in accordance
with prevailing trade practice for plumbing work:
- Use suitable seals (bre seals, o-rings).
- Use Teon tape or hemp.
- Use sealing paste (synthetic depending on the case).
• Installing the hydraulic kit
- Remove the front plate and cover.

• 1 - Assemble the 2-circuit kit. Fix the support.
• 2 - Install the 2-circuit kit. Observe the correct ow
direction. It is imperative to observe direction of
assembly of the valve:
Channel 1: HP ow mixed circuit (CC2).
Channel 2: mixed heating ow (CC2).
Channel 3: mixed heating return(CC2).
When the motor turns counter-clockwise, the
mixing control valve is opened (hotter).
• 3 - Install the hose.
• 4 - Fitting the non-return valve on the direct circuit
ow (CC1).
Remark:
• 5 - Fitting the ow sensor. Fix the heating ow
temperature sensor with the tightening ring to the CC2
mixed circuit ow piping.
Good contact must be maintained between the heating
ow sensor and the pipework. The contact surface
between the pipework and the sensor must be free of
rust and paint and the xing collar must be tightened well.

Electrical connections
Ensure that the general electrical power supply has
been cut o before starting any repair work.
The electrical installation must be conducted in
accordance with the prevailing regulations.
The electrical connections must only be made when all
the other tting operations have been completed (xing,
assembly, etc.).
Remark: In the case of a heated oor, connect the
oor heating safety device into the connector of
the oor heating pump (X110 - CC2: Mixed circuit,
X12 - CC1: Direct circuit).
Make the following connections:
• 6 - Circulation pump CC2 (Mixed-circuit).
• 7 - Mixer valve.
• 8 - Initial sensor.
Good contact must be maintained between the heating
ow sensor and the pipework. The contact surface
between the pipework and the sensor must be free of
rust and paint and the xing collar must be tightened well.
• 9 - Shunt on "M".
• 10 - Interconnection between RVS and AVS.
• 11 - Power supply AVS regulation board. Remove the
insulator of the AVS board’s power connector. Connect
the power connector to the AVS board. Please refer to
the instructions for the extension regulation kit.
• 12 - Room thermostat or Room control unit.
• () - Apply the kit’s label on the inside of the hydraulic
unit’s front plate, over the wiring label.
►
Pre-utilization check
