Continuous flow gas water heaters can be fitted with optional controllers as long as they
are not being used in conjunction with a solar system. There are 2 types of controllers
available, standard or deluxe:

Kitchen

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 an 244, 274, 874 series model or 48°C when
connected to an 246, 276, 876 series model.
246, 276, 876 series 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.
