Installation Steps

Step 1: Turn OFF the power and remove the old thermostat

Before removing the old thermostat, take a picture of its wiring for reference. Ensure mains power is switched off.

Step 2: Prepare Receiver Box for installation

Find a suitable location near the boiler. Loosen the front screw to remove the cover. The Receiver Box requires 230V power.

Needed during installation:

• Cable with 2 wires from the Receiver Box (R4H810A) to the thermostat.
• Cable with 2 wires from the boiler to the Receiver Box.

Step 3: Install the Receiver Box

Refer to the wiring diagrams for specific connections.

A) Wall box or Rear Wiring: Hinge open the terminal block flap to access cables and wall box screw holes.

B) Surface wiring: Use cable clamps to secure the surface wiring (max 6 mm diameter, min 0.25mm², max 1.5mm²).

C) Replace the cover: Locate hinges at the top of the cover and wall plate, close the cover, and secure with the screw.

Step 4: Install the T6 thermostat

Remember to use the same wires connected to the Receiver Box when connecting to the thermostat.

A) Using a screwdriver: Open the wallplate terminal cover to connect wires.

B) Connect wires: Connect the 2 thermostat wires to the 'T' and 'T' terminals and close the cover.

C) Attach thermostat: Attach the thermostat to the wallplate when finished.

Step 5: Complete installation

Turn ON mains power to the heating appliance and Receiver Box. After powering up both devices, the green LED should be on.
