GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM FLYING LEAD LOW LIMIT THERMOSTAT TLFL SERIES CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 ACCESSORIES - INCLUDED WITH F ENCLOSURE OPTION PRODUCT DESCRIPTION The single point flying lead 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 6 mm (0.236”) OD X 50 mm (2”), 304 series stainless steal probe. Standard wire length is 3.05m (10’). 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 provided for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. A typical application for the flying lead type probes is to monitor a single point temperature within the duct. Install the probe in a straight section of duct at a suitable distance downstream from any heating, cooling or humidification devices. Drill a 3/8” hole in the top of the duct and hang the sensor in the airstream. The enclosure provides mounting tabs for ease of installation.
