Diagram
OSO Ecoline cylinders
can be fitted with all types of
boilers.
Standard boilers operate using
room and cylinder thermostats.
Please follow upper diagram:
‘Wiring for Standard Boiler’.
Many popular boilers now use a
thermistor principle. A thermistor
temperature sensor is supplied
with the boiler to attach to the
cylinder. Temperature informa-
tion is relayed back to the boiler
control system.
A clip is provided to secure the
sensor on the EcoLine cylinder.
The supplied motorised valve
must be used in accordance with
Building Regulation G3. This is
wired from the thermal cutout on
the cylinder thermostat.
Please follow lower diagram:
‘Wiring for Thermistor Controlled
Boiler’.
Both wiring plans shown is
based on the use of a 10-way
Junction Box (Honeywell Part
no. 42002116-001).
Junction Box terminal 8 is
switched live and, if needed, ter-
minal 10 is pump live.
