PRESET OUTLET TEMPERATURE SETTING
The factory preset outlet temperature setting of the water heater is:
•
874 series
If a temperature controller is connected to the water heater, this will override the preset outlet temperature
setting and the maximum temperature setting will be:
Maximum Outlet Temperature
Kitchen controller connected
Bathroom controller only connected
It is usually not necessary to check or adjust the factory preset outlet temperature setting 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 an 874 series water heater is installed as a gas booster to a solar water heater, the preset outlet
temperature setting 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 setting 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
