2.2 INSTALLATION
2.0 INSTALLATION
The BoilerMate A-Class incorporates a pump overrun for the boiler pump and
terminal L2 on the terminal strip (as shown on page 23) should only be used if
the boiler requires a permanent live for another purpose.
The boiler manufacturers wiring instructions should be read in conjunction with this
manual.
Before switching on the electrical supply check all the factory made terminal
connections to ensure they have not become loose during transit.
Frost Protection
When frost protection is required for the whole house or where a base temperature
is required during cold weather the central heating and hot water control rocker
switches should be put in the constant position and the room thermostat adjusted
to a suitable setting.
When the location of the boiler means that frost protection is required for the boiler
circuit only a frost thermostat and pipe mounted thermostat should be fi tted in the
normal way and wired back to the special terminal provided in the appliance as
shown below.
