General
The Thermatronic Control System is a battery operated gas fire control system that uses a microprocessor to provide
the working sequences needed by the fire, and when used with an oxypilot has all the safety features required by law
and CE approval.
Commands are accepted by the microprocessor when buttons are pressed. An audible beep means that the command
is received, and the push button should immediately be released.
Using The System
Control can only be achieved if the transmitter is pointed at the fire.
The red light will flash each time you press a button on the handset.
A - Ignition
Simultaneously press and hold the red button and the right upper button (linked by line)
until a short acoustic signal confirms that the sequence has begun, then release the
buttons. Continuous audible signals confirm that ignition is in progress. When pilot
ignition is confirmed the motor will open the valve to maximum flame height
– this takes
about 30 seconds.
B - Flame Height Adjustment
Press the small flame button until the flame height is at the desired position. If you try to
go beyond the preset low flame minimum height the main burner will turn off leaving the
pilot burner alight (this is the standby position). You will learn from experience the preset
low flame minimum height.
To relight the fire from the standby position, or to increase the flame height from low
flame, press and hold the large flame button until the desired flame height is achieved.
Please note that you can have the flame height anywhere between maximum and preset
low. For fine adjustment simply tap the up or down arrows.
C - To Switch Off
Press the red/off button on the handset.
D - General
Battery replacement is recommended at the beginning of each heating season, or when an acoustic error message
sounds during ignition.
Error Message

receiver are nearly discharged.
Error Message
– 5 second continuous tone – probable cause – cable disconnected or on/off switch on valve is in off
position.
