CP318
INSTALLATION INSTRUCTIONS
Combined Time Control and Room Thermostat
The CP318 combined wireless room stat and timeswitch allows a
combi boiler system to have a room thermostat added without the
need for any additional wiring.
Replacing the existing timeswitch with the CP318 will allow the
room thermostat to be connected wirelessly producing immediate
energy savings in houses where no previous room thermostat
has been fitted.
The device is intended to upgrade existing combi boiler systems
that do not have an existing room thermostat. It is not intended for
new installations where it will be necessary to install two heating
zones in order to comply with current Building Regulations.
