fitted with all types of boilers and heat
pumps operating using room and
cylinder thermostats.

'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 additional cylinder
thermostat, wired as high limit
stat. Please follow lower diagram:
'Wiring for Thermistor Controlled
Heat Pump"
