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.
