In-series Gas Boosting Temperature controllers must not be fitted if this water heater is installed as part of a solar water heater system because water at a temperature much higher than the controller setting can be delivered. If a solar pre-heater has been installed to an existing Integrity water heater installation then a solar bypass valve or a comparator must be fitted at this water heater and any controllers, if fitted, must be disconnected and removed.
871024-C Solar Hiline Installation Note: This plumbing diagram is also applicable to 871024 & 871024-B model heaters fitted with a comparator. For more information on comparators refer to page 17.

Removing a Solar Bypass Valve and Installing a Comparator 1. Ensure power and water to the water heater is isolated. 2. Remove the front cover (refer to component procedure 1 on page 56). 3. Locate the 2 pin wiring plug in the wiring loom to the cold sensor mounted on the water body (refer to fig 1) and disconnect. 2 pin cold sensor wiring plug disconnected Cold sensor Fig 1 4.

Tempering Valves 875 series models comply with AS/NZS 3498 and therefore do not require a tempering valve. On 871 series models where a tempering valve is fitted and there is not a separate untempered line for the kitchen or laundry areas, the Kitchen temperature controller will be able to display temperatures above 50oC however the delivered water temperature at the tap will be that set by the tempering valve which will be no hotter than 50oC.
• An Assistance call button provides a voice or alert tone when pressed that is audible on all controllers. One, two or three controllers can be installed, however if a Bathroom controller is installed without a Kitchen controller then the maximum selectable hot water temperature will be limited to 50oC when connected to an 871 series model or 48oC when connected to an 875 series model. 875 series models are factory set and limited so that they cannot deliver water hotter than 48oC.
ON / OFF button This button must be pressed once to turn on the controller. The light in the button will glow when the controller is on. A controller cannot be turned on if water is flowing from a hot tap. To turn off a controller, press the on / off button once. The light will go out. A controller can be turned off whilst water is flowing. Priority light This light will glow on a controller when that controller has priority.

How to Fault Find When conducting fault finding techniques it is important to understand that the same error code with a different sequence number can be displayed at different points during the operational sequence of the water heater. It is important to determine where the fault occurred in relationship to the operational sequence of the water heater before commencing fault finding tests, as the tests may differ even though the same error code can be displayed.
About the Operational Flow Charts The Operational Flow Charts provide information on the start up sequence and, in the event a failure occurs at any point of the start up sequence, what error code will be displayed. When a fault occurs, an error code and sequence number will alternate in the LED display. The Sequence Number Table below indicates the section of the operational sequence (boxed numbers on the operational flow chart) where the fault occurred.

Error Codes The following table outlines the error codes, possible causes and diagnostic tests to conduct. More detailed diagnosis is outlined in the fault finding and operational flow charts.
Diagnostic Test Points Refer to wiring diagram, page 6, for connector and wiring positions.
Maintenance Information Information relating to both the current and past operation of the water heater can be obtained from the memory; this information is referred to as the maintenance information. The table below details the information that can be recalled from the memory i.e. to view the current temperature being measured by the outlet thermistor select 5Y, refer to page 34 for the procedure to display maintenance information.
Displaying Maintenance Information Voltages up to 240 volts will be present within the water heater, take care not to touch wiring terminals. Use an insulated tool when operating the DIP switch or MIN and MAX buttons. At the Water Heater 1. Remove the front panel from the water heater. 2. Using an insulated tool, turn DIP SWITCH 1 on (refer to figure 1). 3. Use the MIN button to change the left digit (0→1etc.
Resetting Error Codes Most Error Codes can be reset by shutting off the hot water flow and turning the controllers (if fitted) off and then on again. It may also be necessary to isolate and restore the power. Where controllers are not fitted it may be necessary to turn the power off at the water heater to clear the error code. Voltages up to 240 volts will be present within the water heater, take care not to touch wiring terminals. Use an insulated tool when operating the DIP switch or MIN and MAX buttons.
