OUTLET TEMPERATURE COMPENSATION ADJUSTMENT – 876 SERIES
The maximum outlet temperature of an 876 series 824, 826 and T26 model water heater may be adjusted to
compensate for temperature losses in the pipe work between the water heater outlet and sanitary fixtures. The
876 series is available in Australia only.
Warnings
After adjustment, the water temperature from the first tap in the hot water pipe work after the water heater
used for personal hygiene purposes, such as in a bathroom or ensuite, MUST NOT exceed:
The temperature displayed on a temperature controller connected to the water heater, or
50°C if a temperature controller is not connected to the water heater.
If there is a tap, such as a kitchen or laundry tap, in the hot water pipe work between the water heater and
the first tap used for personal hygiene purposes, then it is possible for a water temperature to be delivered
from that tap of up to 3°C higher than the setting shown on the controller.
It is necessary to have the electrical supply to the water heater switched on during stages of the outlet
temperature compensation adjustment procedure.
Warnings
The removal of the front panel will expose 240 volt wiring. Take care not to touch wiring terminals. The
adjustment must be carried out by a qualified person.
This procedure will involve the adjustment of dip switches. Adjustment of a dip switch should only be made
with an insulated tool.
Before Commencing the Procedure
This procedure cannot be conducted:
With a temperature controller connected to the water heater.
A temperature controller(s) connected to the water heater must be disconnected prior to the
commencement of this procedure. Refer to “Disconnecting a Temperature Controller(s)” on page 79.
With an Ez-Link system set up on the water heaters.
The DIP switches need to be reset to the off (down) position on both water heaters prior to the
commencement of this procedure.
The Ez-Link cable does not need to be disconnected.
The Outlet Temperature Compensation Adjustment procedure has to be performed individually on
both water heaters.
Whilst the procedure is being conducted on one water heater, the other water heater has to be
isolated by turning off the cold water isolation valve to the water heater.
Disconnecting a Temperature Controller(s)
To disconnect the temperature controller(s):
1. Switch off the electrical supply at the power
outlet to the water heater.
2. Unscrew and gently flip down the electrical
cover on the underside of the water heater.
3. Loosen the terminal screws to release the
cable lugs.
4. Withdraw the cable lugs, ensuring they are
well clear of the terminals.
