Y-plan Wiring
PAW cylinders can be
fitted with all types of boilers and
heat pumps operating using room
and cylinder thermostats. Please
follow upper diagram:
‘Wiring for Standard Heat Pump’.
Thermistor controlled Heat
Pumps/Boilers
Many popular Heat pumps now
use a thermistor principle. A
thermistor temperature sensor is
supplied with the Heat Pump to
attach to the cylinder.
Temperature information is
relayed back to the Heat Pump
control system.
A Pocket is provided (see below
to secure the sensor on the
PAW cylinder. The
probe is run through a channel
from base of cylinder to the
immersion housing and housed
there in a pocket. The thermistor
cable should be secured using
the supplied clamps in the bottom
opening of the channel. A
motorised valve must be used in
accordance with Building
Regulation G3. This is wired from
the supplied cylinder thermostat,
wired as high limit stat Please
follow lower diagram:
‘Wiring for Thermistor Controlled
Heat Pump’.
Using Additional Cylinder Thermostat
as high limit stat only:
- coil the grey temperature
probe wire inside additional
cylinder thermostat box and insert
black probe into thermostat pocket
of cylinder then turn dial on front to
