TEMPERATURE CONTROL – STANDARD

TEMPERATURE SETTINGS – STANDARD CONTROLLER
The temperature settings of each type of controller are:
Bathroom1 & 2 37 C to 46 C (in 1 C increments), 48 C*, 50 C
Kitchen 37 C to 46 C (in 1 C increments), 48 C*, 50 C, 55 C, 60 C
* limited to 48 C on an 876 series model.
The installation of a Bathroom controller(s) only (i.e. no Kitchen controller) limits the temperature setting of
the water heater to a maximum of:
874 series 50ºC
876 series 48 C
regardless of the preset outlet temperature setting of the water heater.
The installation of a Kitchen controller will allow a maximum temperature setting of:
874 series 60ºC
876 series 48 C
regardless of the preset outlet temperature setting of the water heater.
If controllers are not installed, the water heater defaults to the preset outlet temperature setting. This may be
up to:
874 series 60°C
876 series 48 C
Refer to “How Hot Should The Water Be?” on page 5.
On a building fitted with a temperature limiting device such as a tempering valve and where an 874 series
water heater is installed without a separate untempered hot water line to the kitchen, laundry or other non-
ablution area, although the Kitchen controller will be able to display temperatures above 50°C and the water
leaving the water heater will be at the set temperature, the maximum water temperature which can be
delivered to the hot water outlets in these locations is determined by the temperature setting of the
temperature limiting device. This is usually 50°C.
To enable the delivery of water temperatures above 50°C to the kitchen, laundry or other non-ablution area,
separate untempered pipe work must be installed from the water heater to the hot water outlets in these
locations.
