warm
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:
• 871 series
• 875 series
regardless of the preset outlet temperature setting of the water heater.
The installation of a Kitchen controller will allow a maximum temperature setting of:
• 871 series
• 875 series
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:
• 871 series
• 875 series
Refer to "How Hot Should The Water Be?"
On a building fitted with a temperature limiting device such as a tempering valve and where an 871 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.
