Maxitrol TS144C Sensor Els PW 17895 the sensor resistance profile mustThe Maxitrol TS144C is a high precision discharge air temperature sensor designed specifically for integration with Selectra indirect gas fired heating systems. Engineered for modulation control, this thermistor based sensor monitors airstream temperatures to provide real time feedback to the amplifier, ensuring accurate burner adjustment. It features a dual range capability, operating within 20F to 60F for minimum settings and 80F to 140F for maximum
