Titus HVAC D21-TS Relay Thermistor Tstat Signal

The Titus HVAC D21-TS Relay Thermistor Tstat Signal is a component included in some HVAC systems, especially air handling units and packaged rooftop units. It is crucial in controlling the temperature as it acts as an interface between the thermostat and the furnace or air conditioning system. The thermistor, a temperature-sensitive resistor, detects changes in the outside temperature. This information is transmitted to the relay, which acts as a switch, enabling or denying the heating or cooling system depending on the thermostat's predetermined temperature settings. This ongoing cycle ensures that the serviced space stays pleasant. While the particular benefits of the D21-TS may not be readily available, the broad purpose it meets contributes to efficiency.
