Davey POOL AND SPA GAS HEATERS - Manual (Page 14)

Part No: 96131430D 14 Rev: 2
Caution! Motorised valves must never be installed so that they can move through a closed inlet position while the pump is
operating and allow the system to pressurise. This situation will void warranty and may significantly damage the pool heater and
other system equipment and possibly lead to personal injury.
Note: Control of motorised diverter valves requires connection of the valve actuators to the 24VAC terminal strip included in the
pool heater. This terminal strip is built as standard on pool heater models 200 to 430 but is not included on any other model. A
relay may be added by a licensed electrician in accordance with the wiring diagram included in this booklet to provide this function.
Note: Wired connection of actuators must be completed by a licensed electrician.
SERVICE
Caution! Always isolate all connections to the heater, including any pump connections, before commencing any service work.
Only a properly trained service technician should carry out work on your pool or spa heater. Regular service (at least annually)
should be carried out to ensure that the gas valves and burner are clean and free from damage and that the heat exchanger is
unobstructed and free from sooting.
It is recommended that prior to commencing operation of your pool heater each year a service inspection be undertaken.
PROGRAMMING OF HEATER CONTROLLER
The controller located on the front of your Davey heater is capable of both manual and programmable operation. The following
instructions describe how the controller may be programmed for timer operation.
Before the controller can be programmed the time of day clock and day of week must be set.
SETTING TIME & DAY
Before the heater is operated 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.
AUTO MODE
Auto mode allows the controller to:
1. Turn the pool heater on or off over 4 separate time periods each day.
2. Control water temperature.
3. Control mode settings (Pool or Spa)
4. Control and auxiliary equipment that may be connected via the Davey Equipment Interface Box (if installed).
Auto mode can be selected by pressing the PROG button and releasing. AUTO should now be displayed. The heater has been
factory set with four default time periods. These will be used if no other program is set and AUTO is selected on the controller. The
following table shows the factory set AUTO mode program settings. The controller will retain all program settings even with the
removal of the power supply.
