2.2 INSTALLATION
2.0 INSTALLATION
The SysteMate 2000 incorporates a pump
overrun for the boiler pump and terminal 6
on the terminal strip (as shown on page 22)
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, then a frost thermostat
should be wired across plug in terminals 21
and 23 on the A.C.B board.
An alternative to fitting a frost thermostat
would be to set the programmer to constant
during the time required and adjust the room
thermostat to a suitable setting.
When frost protection is required for the
boiler circuit only a frost thermostat and pipe
mounted thermostat should be fitted. The
pipe thermostat should be mounted on the
primary return pipe adjacent to the boiler and
both thermostats should be wired from the
terminal strip as shown opposite.
