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 50°C
876 series 50°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 60°C – AU 55°C – NZ
876 series 50°C
regardless of the preset outlet temperature setting of the water heater.
If there is no controller installed, the water heater defaults to the preset outlet temperature setting. This may
be up to:
874 series 75°C
876 series 50°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.
On a building fitted with a temperature limiting device set to 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.
