Maxitrol TS121B Temperature Sensor Els PW 17895 This restricted oil return oftenThe Maxitrol TS121B is a high precision discharge air temperature sensor engineered for gas fired heating systems requiring elevated setpoints between 120F and 170F. Designed for seamless integration with Maxitrol Series 20 30 and 21 31 electronic modulation systems, this thermistor based component provides the instantaneous feedback necessary for the Selectra modulator regulator valves to maintain stable discharge temperatures.
