1. Wiring to a standard combi setup (typical)
The setup show below is a standard combi system which is common to most
homes. Combi systems may or may not include a 'room thermostat' such as
the one pictured. This is wired into the room thermostat terminal. Even if
there is no existing room thermostat, a combi boiler will always include a
room thermostat (RT) terminal into which a thermostat can be wired. This is
where the LightwaveRF Boiler Switch should be connected (see next page).
