Heating scenarios
1. (Intermediate): Remote control of the Boiler
Required: Boiler Switch, Home Thermostat, Heating Remote
It is really comfortable and convenient to be able to have direct control over
the house temperature without having to get up and alter the thermostat or
boiler. This can be achieved using the LightwaveRF Home Thermostat,
Boiler Switch and Heating Remote. You can turn the temperature up and
down, boost the heating for an hour or simply turn it on/o . Use the Remote
to control the Home Thermostat from the comfort of the sofa, and this will,
in turn, relay the commands to the Boiler Switch.
