TION
The BoilerMate A-Class OV SOL incorporates a pump overrun for the boiler pump.
If a permanent live is required for the boiler then use L3 which is live whenever
the power ON/OFF rocker switch is in the ON position
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 channel (2) of the clock 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 then a frost thermostat and pipe mounted thermostat should be fitted in the
normal way and wired back to the special terminal (SL-F) provided in the appliance
as shown below.
