INSTALLATION – CONTROLLERS
CONTROLLERS
The Aquamax CG20 series of continuous flow water heaters can be installed with Aquamax controllers to
enable the user to control the temperature of the delivered water from the outlet of the water heater.
There are three types of controller. They are the Kitchen controller (PN AQ3264101, including cable),
Bathroom1 controller (PN AQ3264102, including cable) and the Bathroom2 controller (PN AQ3264103,
including cable).
The controllers are identified by a
„K‟ (Kitchen controller), „B1‟ (Bathroom1 controller) or „B2‟ (Bathroom2
controller) located on the front bottom left hand corner of the controller.
The controllers are designed to be hard wired into the water heater using either the Kitchen controller cable
(PN 299856) or the Bathroom controller cable (PN 299857).
Notes:
One, two or three controllers can be installed. Only one of each type of controller can be connected to
the water heater. Therefore, a maximum of three controllers only can be connected to each water
heater.
A Bathroom2 controller can only be installed if a Bathroom1 controller is installed.
An additional Kitchen controller cable or Bathroom controller cable can be used if an extension of the
cable length is required.
It will be necessary to cut an opposite end off both cables to be installed in order to wire them together.
Alternatively, the cables may be extended using two-core flex with a minimum cross-sectional area of
0.5 mm

.
Other manufacturers‟ controllers are not suitable to and cannot be installed with this water heater.
Warning: Temperature controllers must not be fitted to this water heater (CG20-60 model) if it is
installed as an in-series gas booster with a solar water heater because water at a temperature much higher
than the controller setting can be delivered. If a solar water heater is installed to an existing water heater
installation, then all controllers must be disconnected and removed.
Location
– The controllers must be installed in dry, shaded and clean locations.
Do not install the controllers:
Near a heat source, such as a cook top, stove or oven. Heat, steam and smoke will interfere with the
electronic components of the controllers.
In direct sunlight.
In or near a wet area. The controllers are not waterproof. Water may damage the controllers.
Outdoors. The controllers are not weatherproof.
