It is recommended that the boiler is controlled by a programmer
and room thermostat. A suitable room thermostat is supplied in
the wall mounting pack.
Thermostatic radiator valves may be installed in addition to the
room thermostat.
Note: For further information, see The Building Regulations

All system controls are wired into the black electrical connector
plug situated on the right hand side of the wall mounting jig.
If electrical controls are being used the links between terminals
