Operating principle
When the heat pump cannot supply the amount of
energy required, the 3-way distribution valve shunts the
circuit through the boiler to provide additional energy.
The heat pump can be prevented from operating and
the boiler forced to operate by means of control contact
EX1 (bypass).
- Please refer to the manual provided with the heat
pump.
Boiler connection kit / Installation / 2029 - EN
This corresponds to the preset congurations 3 and 4
on the heat pump’s hydraulic unit’s regulator (line 5700).

►
Hydraulic connections
The connection must comply with good trade practice
according to local building regulations.
Tightening torque: 15 to 35 Nm.
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).
Installation instructions
Do not position the servomotor under the valve.

Remove the front panel.
■ 1 - Put the expansion vessel in position "maintenance".
■ 2 - Remove and suppress the exchanger’s ow pipe.
■ 3 - Fit the pipes of the kit.
Carefully comply with the direction for tting
the distribution valve.
- Way AB : Inlet from the hydraulic unit.
- Way A open : heat pump + boiler operating.
- Way B open : heat pump operating alone.
■ 4 - Make an incision in the insulator and clamp the
ow sensor on the facility’s ow pipe. Apply adhesive
tape on each side of the incision.
Good contact must be maintained between the heating
ow sensor and the pipework.

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, insert the
oor heating thermal safety device between the X12
connector and the oor heating circulation pump.
Make the following connections:
■ 1 - Distribution valve (deviation boiler) on the X13
connector.
■ 2 - Connect the boiler control to the X14 connector.
Please refer to the instructions supplied with the boiler.
■ 3 - (Only Single service HP) Disconnect the ow
sensor of the HP. Connect the provided ow sensor
using the provided bundle.
■ () - Stick the label of wiring inside the front plate of the
hydraulic unit.
