Notes.
1. Some earth wires are omitted for
clarity. Ensure proper earth continuity
when wiring.
2. Numbering of terminals on
thermostats is specific to the
manufacturer.
3. This is a fully controlled system - set
the boiler thermostat to maximum.
4. Switchmaster 'Midi' is similar in
operation but the wiring differs slightly
- see the manufacturer's literature.
