4.9.2 Sensor Installation
To access the DHW sensor mounting
bracket, the dual thermostat assembly
must be removed from the cylinder as
shown in Figure 10. Two mounting
screws must be removed before
obtaining access.
Figure 10: Sensor Bracket Access
Next remove the insulation foam (A) to
access the sensor mounting plate (B)
and remove the M5 fixing screws in the
four corners of the plate.
If an additional sensor is required,
simply insert it into the adjacent sensor
holder.
Figure 11: Sensor Bracket Removal
Orientate the sensor mounting plate to
allow access to the phials (four clips in
the centre of the sensor mounting
plate).
Be careful not to kink the capillaries
that connect the thermostat bulbs. The
sensor mounting plate will have two
vacant slots for additional sensors.
Slide the sensor into place as shown in
Figure 12.
Figure 12: Fitting the Sensor
To replace the sensor mounting plate
in position, simply refit the four fixing
screws and secure the plate against the
cylinder bracket.
It is important to take care that none
of the cables become damaged during
this step and that good contact is made
between the cylinder wall and the
sensor(s).
