Room thermostat connection
- Introduce the thermostat wire
- Loosen the cable clamp using a screwdriver and insert the
wires leading from the room thermostat one at a time.
- Connect the wires to the terminals as indicated in the gure
below, removing the link
- Make sure that they are well connected and that they are
not subject to stress when the control panel lid is opened or
closed
- Close the ap again, then replace the control panel cover and
the front casing.
Outdoor sensor connection
- Introduce the outdoor sensor wires
- Loosen the cable clamp using a screwdriver and insert the
wires leading from the outdoor sensor one at a time.
- Connect the wires to the terminals as indicated in the gure
below;
- Make sure that they are well connected and that they are

The boiler can be connected to a central heating system that
uses two zone valves to allow connection to an indirect storage
cylinder.
There are two wiring diagrams shown, one for the connection to
an Unvented Cylinder and one for connection to an open vented
cylinder.
In both cases the boiler connection is shown as TA1.
When connecting the boiler to an external cylinder do not run
240V cables and the cables for the room terminal together, use
separate cables to prevent induced voltage on the low voltage
switching circuit.
Note: the use of a ‘y’ plaN system is Not possible with the clas
he system boiler due to the low Voltage switchiNg of the appliaNce
uNless suitable relay coNtrols are used.
Important!!
Ensure that a balancing valve is tted on the
cylinder return and balanced correctly at
commissioning stage.
