GB If the thermostat RET2000B-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 5.

Step 2 RET2000B-RF - Insert 2xAA alkaline batteries. If the

RET2000B-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 RET2000B-RF. Release buttons

A steady aerial icon on RET2000B-RF conrms that the devices

are now paired and ready for control of your heating or cooling

systems.
