PRESET OUTLET TEMPERATURE SETTING
The factory preset outlet temperature setting of the water heater is:
874 series
872 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:
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.
