2.5 RESTORING COMMUNICATION WITH A NON-DISPLAY HANDSET.
If the valve is operating correctly when controlled with the on-board control buttons but the handset green light
pulses (approx. once per second) when activated then either:-
• The handset is paired correctly but is out of range of the gas fire control.
• The batteries in the gas fire control are flat, or have bad connections.
• The slide switch on the gas fire control is in the OFF (0) position.
• The handset pairing has been broken.
IMPORTANT NOTE: THE HANDSET IS PAIRED WITH THE VALVE IN YOUR FIRE DURING
MANUFACTURE. PAIRING IS NOT LOST IF BATTERIES ARE REMOVED.
To re-establish communication between the valve and the handset, the handset must be reset to factory
condition to allow pairing to commence.
To reset the non-display handset, follow the below instructions:-
1. Ensure good and properly connected batteries in the handset and valve.
2. Hold the handset to activate buttons (green light will illuminate).
3. Press and hold SET for 10-15 seconds, until red and green lights flash simultaneously.
4. Whilst red and green lights flash together, quickly remove one battery, wait for about 30 seconds, then
replace battery and battery cover.
5. Hold handset to activate buttons, the green light should now be flashing multiple times per second
meaning it is ready to be paired with the valve.
A video companion for this process is available here, or search “TESC Gas Control - Displayless Handset factory
reset (to enable to be paired again)”.
NOTE: IF THE RED AND GREEN LIGHTS DO NOT FLASH TOGETHER THE HANDSET IS PROBABLY ALREADY
RESET AND READY FOR A PAIRING REQUEST.
2.6 PAIRING THE VALVE WITH A NON-DISPLAY HANDSET.
Ensure the handset and fire control valve have good batteries as described in section 1.3.
If the handset is in factory reset condition (as section 2.5) the green light will flash rapidly when the handset is
activated.
Follow the steps below:-
1. Ensure the power isolation slide switch on the valve is in the ON (I) position.
2. Place the unlocked handset near the fire (ideally within 1 metre).
3. Simultaneously press and hold the + and – buttons on the valve, the red light on the valve should
begin to flash rapidly.
4. Immediately release the + and – buttons, and press the power button located directly below. n.b.
the power button must be pressed within 1 second of releasing + and – buttons.
5. If steps 3 and 4 are completed correctly, the handset will produce an audible tone, the green light will
be flashing slower than previous. The pairing must now be accepted within 60 seconds – if pairing not
accepted within 60 seconds the green light will go out.
