GENIE C & S - SETUP & SERVICE MODES
WARNING: BEFORE COMMENCING OR COMPLETING ANY ELECTRICAL WORK ON THE APPLIANCE, IT IS
RECOMMENDED THAT THE BASIC SAFETY CHECKS FOR EARTH CONTINUITY, SHORT CIRCUIT, POLAR-
ITY AND RESISTANCE TO EARTH ARE MADE. ALL WORK CARRIED OUT SHOULD FOLLOW GUIDELINES
LAID DOWN BY THE I.E.E.
Operation
The Heater requires Mains on both the Live (L) and Switched Live (SL) connection to be able to run. It is delivered
with a link between them which can be removed if a separate Heater switched live is going to be used.
To run, the Heater must have a Mains supply, Gas, Pool Pump pressure sufficient to activate the Pressure Switch,
all safety switches closed and a pool temperature below the set point.
If all the above are correct then the Gas Ignition Control starts the Ignition sequence:
1. The Fan and internal Pump runs as a pre-purge of the Heat Exchanger
2. After a few seconds a spark is created at the electrode and the burner is lit.
3. The burner flame is sensed and the spark is removed.
4. The Fan speed is then changed to the required speed according to the modulation curve.
5. If it fails to light the burner the spark will stop and the Fan and internal Pump will run on as a post-purge of
the Heat Exchanger.
6. The ignition sequence will be repeated up to five times, then the control will lockout and will require
a reset to start again.
Safety Controls & Lockouts
The Pool Thermostat Control indicates the actual and set temperature of the pool and also displays all the lock-
outs. The next pages detail the fault conditions, the indicators, the display and the actions required.
User Setup Mode
Turn off on the Panel Switch. Turn on with the Panel Switch whilst pressing the Lock/Reset Button.
The Control is now in User Setup Mode.
The control can now be altered by rotating the Pool Temperature Control Knob to a certain position and then
pressing the Lock/Reset button, then switching off. (See Fig. 9.0)
Example:
To change from Fahrenheit to Centigrade:
Turn Panel Switch OFF then back ON whilst pressing the Lock/Reset button.
Turn the Pool Temperature Control Knob until the display shows ‘F’.
Press the Lock/Reset button once and the display will show ‘C’.
Switch the Panel Switch OFF then back ON again.
The Control will now display in Centigrade.

GENIE C & S - SETUP & SERVICE MODES
Service Mode
This is a special mode used to set the operation of the Control and to investigate fault conditions, it is entered from User
Setup Mode.
Rotate Pool Thermostat knob fully clockwise to show the software version number.
Press the Lock/Reset Button for 3 seconds. The control is now in Service Mode.
It is now possible to change some of the Control’s parameters. To show them, rotate the Pool Thermostat
Potentiometer. To zero or change them, press the Reset/Lock button
To exit, turn the Panel Switch off then back on again.
Test Temperature Display Mode 1 (td1).
Temperatures are displayed to 0.1 degree resolution, not the normal 1 degree.
The display will now show each sensor temperature and cycle around them for each press of the Lock/Reset button.
1. Pool temperature as normally displayed. The green LED will be alight.
2. Pool temperature is dispayed to 0.1 degrees. The green LED will be alight.
3. Heat exchanger flow temperature. The yellow LED will flash rapidly.
4. Heat exchanger combustion temperature. The red LED will flash rapidly.
5. Aproximate pool water flow in l/m for Genie 50 multiply by 0.738 for Genie 35. the red and yellow LEDs
alternate.
Rotating the potentiometer will change the set temperature. Pressing and holding the button whilst one of the tem-
peratures is displayed will ‘lock/unlock’ it on the display for continuous observation.
