REMOTE TEMPERATURE CONTROLLERS
Continuous flow gas water heaters can be fitted with optional remote temperature controllers
as long as they are not being used in conjunction with a solar system.
There are 3 types of remote controller that can be used, standard, deluxe or EziSET
®
.
Standard and deluxe controllers are hard wired whereas EziSET
®
is Smartphone based.
Note: EziSET
®
is not to be used in conjunction with hard wired controllers.
Hard Wired Controllers:
Standard and deluxe controllers cannot be mixed in a single installation; other
manufacturers’ controllers cannot be used.
One, two or three unique controllers can be installed, however if a Bathroom controller is
installed without a Kitchen controller then the maximum selectable hot water temperature
will be limited to 50°C when connected to a 274, 864, 874, 862, 872, 863, 873, 372 series
model or 48°C when connected to a 276, 866, 876 series model.
276, 866 & 876 models are factory set so that they cannot deliver water hotter than 48°C.
When no hot water is flowing, temperatures can be selected between 37°C and 43°C by
pressing and holding the temperature control buttons, to select temperatures above 43°C
press the temperature control button once for each selection.
A controller must be turned on and must display the ‘Priority’ indicator in order to allow
adjustment of water temperature.
When hot water is flowing, the temperature can be increased from 37°C to 43°C only. The
water temperature can be decreased from any setting whether hot water is flowing or not.
