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:
•
PH-246CWHA series
50°C
regardless of the pre-set outlet temperature setting of the water heater.
The installation of a Kitchen controller will allow a maximum temperature setting of:
•
PH-246CWHA series
55°C
regardless of the pre-set outlet temperature setting of the water heater.
If controllers are not installed, the water heater defaults to the pre-set outlet temperature setting.
This may be up to:
•
PH-246CWHA series
60°C
Refer to “How Hot Should The Water Be?” on page 4.
On a building fitted with a temperature limiting device such as a tempering valve and where an
PH-246CWHA 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.
