TEMPERATURE CONTROL 
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. 
  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. 
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. 
  Other manufacturers‟ controllers are not suitable to and cannot be installed with this water heater.
