GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ALL PURPOSE DUCT/IMMERSION LOW LIMIT THERMOSTAT TLAP SERIES PRODUCT DESCRIPTION The single point duct/immersion low limit thermostat incorporates a precision thermistor sensor and provides a Form C relay output (NO/NC) with an adjustable setpoint. The sensor is encapsulated in a 6mm (0.236”) OD, 304 stainless steel probe and is available in various lengths (see ordering chart). All probes provide excellent heat transfer, fast response and 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. The duct type probes are installed through a hole in the side of the duct to monitor a single point temperature within the duct. Since the probes are tip sensitive, select a probe length that places the sensor well into the duct. Install the probe in a straight section of duct at a suitable distance downstream from any heating, cooling or humidification devices. The enclosure provides mounting tabs for ease of installation. NOTE: For immersion applications, T2 series thermowell is required. When using a T1 series thermowell an adapter will be required.
