OPERATION

Boiler Control
The PL07 will turn the boiler on when it receives a call for heat from any of the
installed thermostats via the KL06 wiring centre. Depending on the jumper
settings the boiler will be turned on immediately, or after a delay of three
minutes. Once the thermostats are no longer calling for heat, the boiler will be
turned off immediately.
The boiler is controlled by the use of a Normally Open (NO) latching relay within
the PL07 logic module. The relay is designed for Volt-free operation, and will
work with boilers with 24V AC or 230V AC control systems.
Circulating Pump Control
The PL07 will turn the circulating pump on when it receives a signal from any of
the installed thermostats via the KL06 wiring centre.
The circulating pump is controlled by the use of a Normally Open (NO) latching
relay within the PL07 logic module. The relay is designed for 230V AC switching.
If within a one week period no switching signal has been detected from the KL06
wiring centre, the PL07 will run the circulating pump for five minutes to avoid
any damage to the pump and boiler.
