3 TC-XX Series, TC-XX Series, TF- Series Specifications Thermostats mounted on concrete walls or surfaces that change temperature slowly, have reduced response to changes in air temperature. Response is further delayed by guards that restrict air flow Anticipators to the thermostat. Anticipators are required (parallel for cooling, series or parallel for heating) for any of these conditions and in spaces intended for continuous occupancy; i.e., hotel guest rooms and offices. TC-8X Series Cooling is fixed. TF- Series Heating and cooling; factory-installed resistors are sized for Vac maximum. Fan switch TC-8X Series Marking: Low-Off a -Med-High. Marking: Off-Lo-Hi TC-9X Series a. Construction: Integral two-pole three-position. Sensing element Bimetal. Mounting Flush or 2 x 4 wall box.
