INSTALLATION – CONTROLLERS
74
CONNECTING THE CONTROLLER(S) TO THE WATER HEATER
To connect the controller(s) to the water heater:
1. Ensure the electrical supply to the water heater is switched off.
2. Unscrew and gently flip down the electrical cover on the underside of the water heater.
3. Draw the cable(s) through the electrical
cover.
4. Connect a cable lug from each cable to each
of the remote controller terminals. Each cable
has two cable lugs.
Ensure the terminal screws are seated firmly
and there are no excess wire loops inside of
the electrical cover.
The cable connections are non-
polarised.
Three cable lugs, one from each
controller, can be connected to each
remote controller terminal.
5. Place the cable(s) in the cable holder
notches.
It is important to seat the cables into the cable notches. Failure to do this may cause an unstable contact
or even disconnection of the cables from the terminals if the cables were to be pulled.
6. Refit the electrical cover to the water heater and replace the screws.
7. Switch on the electrical supply to the water heater.
Upon completion of the installation of the controllers, it is necessary to test their operation through the complete
range of functions (refer to
“Temperature Control” on pages 11 to 40).
Upon completion and testing of the installation, explain to the householder the functions and operation of the
controllers and the water heater.
If it is necessary to turn off the water heater on completion of the installation, such as on a building site or
where the premises is vacant, follow the procedure
“To Turn Off the Water Heater” on page 84.
