Honeywell TR21 20KOhm Temperature Sensor

The Honeywell TR21 Temperature Sensor is a vital component in Honeywell HVAC systems. It monitors the ambient temperature in your home and transmits this data to the thermostat. The thermostat then uses this information to regulate your HVAC system's operation, ensuring consistent comfort. The sensor operates over a wide temperature range, typically -30°C to 70°C, making it suitable for various climates. Its compact size, typically between 3 and 6 inches long and 0.1 to 0.2 inches thin, allows for discreet placement within your living space.
