6.0System Details

6.6System Controls & Wiring

This boiler requires a permanent live for operation of the condensate pump and frost protection.

1.To comply with Part L1 of the Building Regulations the heating system into which the boiler is installed should include the following:

a)zone controls

b)timing controls

c)boiler control interlocks

2.Such a system needs to be fully pumped and must provide independent temperature and time control to both the heating and hot water circuits and have a boiler and system pump interlock.

3.The boiler should be controlled so that it operates on demand only. Where it is proposed to effect control by thermostatic radiator valves a room thermostat should also be provided to switch off the boiler when there is no demand for heating.
