Important note RF products: Ensure that there are no large metal objects, such as
boiler cases or other large appliances, in line of sight between the transmitter and
receiver as these will prevent communication between thermostat and receiver.

For insulation thicker than 25mmand up to 55mm thick, use the extra cover supplied as a spacer toensure that the sensor is held infirm contact with the cylinder wall.
Installation
This product should only be installed by a qualied
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 conrms that the devices
are now paired and ready for control of your domestic hot water
system.
