2.27 BOILER WITH EXTERNAL CONTROLS

1. The boiler must be provided with a 4 minute pump overrun

period. Failure to do so may invalidate the boiler warranty.

2. It is preferable that any pump used to circulate water

through an individual boiler is controlled by the local boiler.

Either as a 230V 50Hz supply as shown, enabled by the

Volts Free Contacts e.g. MFR1 or controlled by the option
kit for 0-10V pump control. If not then a pump overrun
function MUST be provided by the controlling system.

3. The pump load and switch on surge current must be within

the limits of the output if it is powered directly from the Volts

Free Contact. The limits are as specified in the Electrical

Specification Table below.

A slave contactor may be used to power the pump where
needed.

4. If the switched live is provided without a Volts Free Contact

then this MUST be taken from the same phase as the
boiler mains supply, preferable through the same isolator.
