GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM OUTSIDE LOW LIMIT THERMOSTAT TLOB SERIES PRODUCT DESCRIPTION The single point outside air low limit thermostat incorporates a precision thermistor temperature sensor and provides a Form C relay output (NO/NC) with an adjustable setpoint. All probes are constructed to provide excellent heat transfer, fast response and are potted to resist moisture penetration. A sun and windshield is integrated into a hinged and gasketed weatherproof Polycarbonate enclosure is included for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The outside temperature transmitter should be mounted on an outside North facing wall, under the eaves which will provide protection from direct sunlight. The outside temperature sensor can be mounted directly to building’s wall face using the provided mounting holes. There is one 0.85” hole for conduit connection. POWER SUPPLY 12 to 28 Vac/dc SENSOR ACCURACY ±0.2°C, 0 to 70°C (±0.36°F, 32 to 158°F) PROBE SENSING RANGE -40 to 50°C (-40 to 122°F) PROBE MATERIAL Stainless steel WIRE MATERIAL PVC insulated, parallel bonded CONSUMPTION 50 mA max RELAY CONTACTS SPDT, Form C contacts (N.O. and N.C.)
