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 remove the front panel from the water
heater.
3. Draw the cable(s) through the cable grommet on the
underside of the water heater.
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 front panel.
The cable connections are non-polarised.
Three cable lugs, one from each type of controller, can
be connected to each remote controller terminal.
5. Refit the front panel and screws to the water heater.
6. 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 9 to 38).
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 76.
