PRESET OUTLET TEMPERATURE SETTING
The factory preset outlet temperature setting of the in-series gas booster is 60°C. The preset outlet
temperature setting can be adjusted. Refer to
“To Check or Adjust the Preset Outlet Temperature Setting”
page 34.
Note:
AS 3498 requires that a water heater provides the means to inhibit the growth of Legionella bacteria in
potable water. When this water heater is used as an in-series booster for a solar water heater it can satisfy
this AS 3498 requirement provided it is energised, the booster preset outlet temperature setting is 70°C or
higher, and that a remote temperature controller is not used.
Note:
Consideration must be given to the delivery temperature to any ablution and public areas such as a
bathroom, ensuite or public amenities. Refer to
on page 17 and to the schematics of
Two Temperature Zones Using A Temperature Limiting Device
on page 18.
TO CHECK OR ADJUST THE PRESET OUTLET TEMPERATURE SETTING
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:
20 litre
55°C (1 flash), 60°C (2 flashes), 70°C (3 flashes)
27 litre
38°C, 40°C, 42°C, 43°C, 45°C, 50°C, 55°C, 60°C, 70°C, 75°C
It is necessary to have the electrical supply to the water heater switched on during stages of checking or
adjusting the preset outlet temperature setting procedure.
Warning:
The removal of the front panel will expose 240 volt wiring. Take care not to touch wiring
terminals. The adjustment must be carried out by a qualified person.
Warning:
This procedure will involve the adjustment of dip switches. Adjustment of a dip switch should
only be made with an insulated tool.
To check or adjust the preset outlet temperature setting:
1.
Switch off the electrical supply at the power outlet to the water heater.
2.
Remove the screws holding the front panel to the jacket.
3.
Gently disengage the front panel and pull forward to remove from the water heater.
4.
Switch on the electrical supply at the power outlet to the water heater.
5.
Switch DIP SWITCHES 3 and 4 to the on (up) position on the I.C. Board.
Note:
For the 27 litre model, this is the DIP 1 set of DIP switches. For the 20 litre models, there is only
one set (DIP 1) of DIP switches.
20 litre models
The red LED will commence a series of flashes, with
three (3) seconds between each series.
If the red LED is flashing the correct number of flashes for
the desired preset temperature, then proceed to step 7, as
no further adjustment is necessary.
27 litre models
The current preset outlet temperature setting will show on
the LED display.
If the temperature displayed on the LED display is the
desired preset outlet temperature setting, then proceed to
step 7, as no further adjustment is necessary.
