Using anexternal contactor, it can control several heaters.The WCRT provides high level accuracy<strong>and</strong> sensitivity with 2.5°F differential. Thecontrol has a SPDT output <strong>and</strong> can be used forheating or cooling.WARNING: Hazard of Fire. The WCRT thermostatis designed for temperature controlservice only. Because it is not fail-safe, itshould not be used for temperature limitingduty.Applications• Can be used to control room temperature inharsh environments regardless of whetherheating or cooling is required.• Tolerates continuous spraying with water,high humidity, airborne contamination <strong>and</strong>moderately corrosive conditions.Features• Shielded sensing bulb is nickel-plated <strong>and</strong>attached directly to bottom of enclosurewhere it is shielded from damage <strong>and</strong> accumulationof insulating particles.• Sealed Noryl case with neoprene gasket toseal out dust <strong>and</strong> moisture. Knob opening isclosed with lubricated “O” ring.• Adjustable Knob setting is accurate to± 2.5°F with large easily-read numerical dial.• Positive OFF for heating is provided bysetting unit to LO position. (At LO Position,heat circuit is open <strong>and</strong> cool circuit is closedat any temperature.)Dimensions3.50(89)3.68(93)Ratings for OtherElectrical ApplicationsType of Maximum Rating (Amps AC)Service 120V 240V 277VLocked Rotor 80 60 50Inductive 16 12 10Pilot Duty 125VA 125VA 125VASuitable for 24 Vac Operation @ 100mAMinimumFront View5.87(150)Side ViewAll Dimensions in Inches (mm )Specifications <strong>and</strong> Ordering InformationVoltage/Current, Resistive Voltage/Current, InductiveWt.Model Type Temp.
