INSTALLATION – CONTROLLERS

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.
The two remote controller terminals are adjacent to each
other and located at the top right of the printed circuit
board (PCB), to the right of the label marked ‘REMOTE
CONTROLLER TERMINAL’.
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.
Up to three cable lugs, one from each type of
controller, can be connected to each remote
controller terminal.
Warning: Do not confuse the remote controller
terminals with the two 100 V terminals under the label
flap marked ‘DANGER 100 V DISCONNECT POWER’ at
the bottom right of the PCB.
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 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 81.
