Attaching the temperature sensor
The temperature sensor lead (supplied) must be run from the heat pump to the
storage tank.
IMPORTANT
Ensuring and maintaining a good
temperature probe contact with
the storage tank will ensure
accurate temperature readings.
Failure to install the temperature
probe/sensor as instructed could
cause the heat pump to run for
longer periods, and result in high
electricity bills for the customer.
1. Remove the element box
cover from the storage tank.
2. Apply a small quantity of
a suitable heat transfer
compound, such as Unick
(available from Dick Smith
electronics) along the back of
the temperature probe and
contact fixing.
3. Place the temperature probe
as high up inside the element
box as possible, and run the
sensor cable down the side of
the element box.
4. Cover all components in
the element box with the
insulation provided, and refit
the element box cover.
5. Remove the electrical cover
plate from the right hand side
of the heat pump. Plug the
other end of the temperature
sensor into the matching
connector. Refit the cover
plate.
6. Run the temperature sensor
over the required length and
fix in place with suitable clips.
Gather any excess cable and
secure with cable ties in a
convenient position.
