GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM GLASS LOW LIMIT THERMOSTAT TLGL SERIES CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 ACCESSORIES - INCLUDED WITH F ENCLOSURE OPTION PRODUCT DESCRIPTION The single point glass low limit thermostat incorporates a precision thermistor temperature sensor and provides a Form C relay output (NO/ NC) with an adjustable setpoint. The sensor is encapsulated in a 31.75mm L x 9.525mm W x 9.525 mm H (1.25” x .375” x .375”) Aluminum probe. Standard wire length is 1.5 m (5’). All probes are constructed to provide excellent heat transfer, fast response and are potted to resist moisture penetration. A hinged and gasketed Polycarbonate enclosure is included for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. Find a suitable location on an exterior window where both the probe and enclosure can be mounted. On one side apply epoxy compound and press firmly against the glass. Hold in place until the epoxy has set. Enclosure provides mounting tabs for ease of installation.
