For insulation thicker than 25mm and up to 55mm thick, use the extra cover supplied as a spacer to ensure that the sensor is held in firm contact with the cylinder wall.
Installation
This product should only be installed by a qualied electrician or competent heating installer, and must be in accordance with local wiring regulations.
!
1. The clamp on sensor should be mounted onto the cylinder wall at a height equivalent to ½ the height of the cylinder. Care should be taken to remove any insulation material from the cylinder and to ensure that the copper surface of the cylinder is clean. See diagram opposite for details.

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).

KEYS LOCKED
To avoid unwanted tampering of the required hot water tem­perature the CET2000B-RF includes a key lock feature which disables the Λ and V buttons.
First set the required hot water temperature using the Λ or V button. Then slide internal DIL switch 4 to the locked posi­tion and mount the CET2000B-RF back on its wallplate (as shown on page 9).

Commissioning
If the thermostat CET2000B-RF and receiver RX1-S have been supplied together in a combined pack, the units have been paired in the factory and no commissioning is required. If the thermostat and receiver have been supplied separately follow the steps below to pair the devices.
Step 1 RX1-S - Ensure RX1-S is wired in accordance with instructions on page 8.
Step 2 CET2000B-RF - Insert 2xAA alkaline batteries. If the CET2000B-RF is not already paired to the RX1-S it will enter it’s learning mode shown by the ashing aerial icon.
Step 3 RX1-S - Press and hold down both the PROG and CH buttons. The PROG LED will light for 1 second when it has paired with the CET2000B-RF. Release buttons
A steady aerial icon on CET2000B-RF conrms that the devices are now paired and ready for control of your domestic hot water system.
