2. Before attaching the sensor to the cylinder using the strap

provided, connect a 2-core cable to the sensor to allow

interconnection to the thermostat setting unit.

3. Apply the contact paste provided to the part of the sensor

in contact with the cylinder and clamp the sensor to the

cylinder wall.

A spacer piece is provided for use with cylinders that have

thick insulation (see page 6).

4. Mount the thermostat wallplate on to a wall next to the

cylinder. Connect the cable from the sensor to terminals 1

& 2 of the wallplate (see wiring diagram on page 7).

5. Now mount the thermostat setting unit onto the wallplate

(see diagrams on page 9).
