Installation of Ideal relay transceiver
1. Isolate power to boiler and heating system.
2. Remove the cover of the relay transceiver and screw the base to the wall,
directly above the existing system wiring if possible.
3. Disconnect and dispose of the wiring to the existing two channel timer and
room thermostat.
4. Make connections as in the diagrams below (except the opentherm wiring
- see next steps overleaf). Secure the wires in place using the cable clamps
provided.
If a frost thermostat is connected it should be from live to connection 8 (C/S On)
5. Power to the boiler and heating system should remain isolated.

*Where the Ideal Touch kit is being fitted to an existing installation (S or Y plan), the wire
connecting any SL IN on the boiler requires disconnecting and making safe. A link wire
should then be connected into the SL1 L-IN connection at the boiler†.
For further details refer to the boiler installation and sevicing instructions.
