Gas Valve Outputs
A gas solenoid valve should be powered using one of the terminals marked [VALVE OUT].
Terminals offer control via mains 100-120V~ or 24V~
When wired to a normally closed gas solenoid valve, the TGC controller can be used to isolate the gas
supply either by; pressing the Off button on the unit; when the configured time runs out or if remote
emergency devices are activated.

Remote Emergency Stop
The Timed Gas Controller can be connected to remote devices with an open /close circuit via the [EM
STOP] volt free switch terminal.
This terminal has a factory fitted link installed (normally closed circuit) and when open will isolate the gas
supply resetting the gas supply timer. No audible alarm will occur
–
only EM Stop LED indicator.
Selectable Automatic Timeout Switches
On the circuit board are two dipswitches used for selecting the automatic gas shutoff timeout.
The controller LED will turn yellow ten (10) minutes before the selected time is reached and when five (5)
minutes remain the buzzer will beep, and the yellow LED will then intermittently flash.
After this time, the gas will automatically shut off until reactivated.
