GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM REMOTE PROBE STRAP-ON LOW LIMIT THERMOSTAT TLRP SERIES PRODUCT DESCRIPTION The single point strap-on 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, 304 stainless steel probe and is available in various lengths (see ordering chart). Standard wire length is 5’ (1.5 m). 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. For best results, thermal conductive compound should be applied to pipe prior to mounting the probe. Find a suitable location along the pipe where both the probe and remote enclosure can be mounted. If necessary, remove a section of insulation from pipe. Position probe directly on the pipe and secure using a pipe clamp. For added security, make 1 to 3 loops of the sensor cable around the pipe and feed through wire hole on the enclosure and secure using the supplied grommet. If applicable, the pipe insulation can be re-applied to the pipe over the probe.
