4.10.1 Thermistor controlled boilers
Many popular boilers now use a thermistor principle.
A thermistor temperature sensor is supplied with the
boiler to attach to the cylinder. Temperature infor-
mation is relayed back to the boiler control system.
A Pocket is provided (see below to secure the sen-
sor on the DELTA Twin Coil VIP 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 us-
ing the supplied clamps in the bottom opening of
the channel. The supplied 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 Boiler’.
