hours for the heater to cool (If the pump has ceased operation the reset time may be shortened by restarting the pump). If the reset
button has failed to illuminate and the temperature display reads less than 32°C, contact your Rheem service agent PH 131031.
SETTING TIME & DAY
Each time that power is reconnected to the heater the internal heater time clock should be set. Each and every time the heater has
been isolated at the GPO, e.g. for service, this process must be repeated.
1. Connect the heater to a 240V 10A GPO and turn on.
2. With the controller displaying OFF, simultaneously press and hold the ▼ and PROG and buttons to access the time set mode.
3. The system time will then flash on the display. To adjust the time of day, press the ▲or ▼buttons until the correct time is
reached.
4. Once the time has been set, press and release the PROG button to access the day of week mode.
5. The day will flash on the display. To adjust the day, press the ▲or ▼buttons.
6. Press and release the PROG button to lock the day setting and return the control to the OFF mode.
OPERATING INSTRUCTIONS
1. Before switching the heater On, ensure all water flow control valves are in their correct position. This can be tested by
manually operating the system pump and ensuring that water is flowing through the heater.
2. Ensure that the gas supply is turned on.
3. Press the POWER button on the face panel of the heater. The heater will display the current water temperature of the pool.
4. Press the ▲button on the control panel of the heater until the desired temperature set point is reached.
5. If initial operation, or if reset lamp is on, press the reset button
6. The heater will ignite when the set point temperature is above the measured water temperature. If a pump is connected to the
heater this will also commence operation.
Note: The heater will not ignite if there is no water flow through the heater.
7. If the heater does not ignite after 90 seconds, turn off the power by pressing the POWER button and wait 1 minute before
repeating all steps.
8. If the heater does not light on the second attempt, turn off the heater and isolate the gas supply and contact your installer or
Davey.
TEMPERATURE SELECTION
Caution ! Prolonged exposure to elevated water temperatures can be hazardous.
Temperature selection is made by selecting either the ▲or ▼arrow buttons located on the face of the heater controller. After
depressing either of these buttons the current desired temperature set point will be displayed. Continuing to press either button will
alter the heater set point. Once the desired set point temperature is selected the display will return to show the current water
temperature, after a short delay.
For continued manual operation of the heater in this manner ensure that the display is not showing AUTO. If AUTO is displayed
pressing the PROG button will return the heater to manual operation.
MODE SELECTION (POOL/SPA)
The MODE button on the control panel enables both the pool and spa temperatures to be set independently. The two set point
temperatures are stored by the heater controller and are used when the desired mode is selected.
To select the desired mode press the MODE button. The selected mode is shown on the heater display. The heater will then
operate according to the mode selected.
If the Pool mode is selected, the heater will heat the water until the pool set point temperature is reached. If Spa mode is selected
the heater will heat the water until the spa set point temperature is reached.
Motorised Valves (if installed)
Models: 200, 280, 350, 430 Only
The pool heater controller included in the above models is fitted standard with a 24VAC output for operation of motorised diverter
valves (if fitted by your pool system installer). Where motorised diverter valves are installed they may be connected to the heater
by the installer so that when the MODE button is pressed, the diverter valves direct flow to and from the desired destination, i.e.
Pool or Spa after a delay of approximately 5 seconds.
