PRESET OUTLET TEMPERATURE
The factory preset outlet temperature of the water heater is:
55°C
If a temperature controller is connected to the water heater, this will override the preset outlet temperature
setting and the maximum outlet temperature will be:
Maximum Outlet Temperature
Kitchen controller connected
55°C
Bathroom controller only connected
50°C
It is usually not necessary to check or adjust the factory preset outlet temperature of the water heater, unless
the customer has a particular requirement for this to be done or it is to be installed as a gas booster to a
solar water heater.
Gas Booster for a Solar Water Heater
Where a water heater is installed as a gas booster to a solar water heater, the preset outlet temperature
must be set at 75
C for the system to operate correctly.
It will be necessary to check and if required to adjust the preset outlet temperature of the continuous flow
water heater when:
it is installed as a gas booster as part of a solar water heater installation
it is an existing continuous flow water heater and a solar preheat water heater is then installed.
Notes:
Consideration must be given to the delivery temperature to any ablution and public areas such as a
bathroom, ensuite or public amenities. Refer to
“Hot Water Delivery”
on page 44 and to
“Schematics of 2
Temperature Zones Using A Temperature Limiting Device”
on page 45.
The water heater, marked “THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 55°C IN
ACCORDANCE WITH AS 3498” on the front panel,
must not
be installed as an in-series gas booster
water heater to a solar water heater, as water temperature greater than 55°C can be delivered from the
water heater contravening its compliance to AS 3498.
TO CHECK OR ADJUST THE PRESET OUTLET TEMPERATURE
The temperature setting will be displayed by a series of flashes from the red LED, with a three (3) second
pause between each series of flashes. The temperature settings and series of flashes are:
