It takes control of equipment by turning on the blower fan and sensing indoor temperature.
What is return sensor?
Description. The Honeywell return air sensor works with the THM5320R1000 equipment interface module to maintain safe indoor temperatures if power is lost at wireless thermostat. ... It takes control of equipment by turning on the blower fan and sensing indoor temperature.

What does an intake manifold temperature sensor do?
Manifold temperature sensors measure the temperature of the air inside the intake manifold. Other sensors measure the temperature of the air entering the engine or the temperature of the air in the surrounding atmosphere. Manifold temperature sensors provide valuable information for several reasons.Jan 8, 2016
What does an air cleaner temperature sensor do?
The air cleaner temperature sensor collects information about the air entering the engine and sends it to the computer so that it can adjust the engine timing, as well as the fuel-to-air ratio. If the air cleaner temperature sensor detects cold air, the computer will add more fuel.Aug 31, 2016
What is the purpose of a discharge air temperature sensor?
The Discharge Air Temperature sensor is used to measure the temperature of the air that is emitted from the air ducts.
What does dat mean in HVAC?
discharge air temperature
Is intake air a temperature sensor?
The intake-air temperature sensor determines the temperature in the suction pipe and forwards the voltage signals arising from the temperature to the control unit. This evaluates the signals and influences the mixture formation and the firing angle.
Where is intake air temperature sensor?
The Intake Air Temperature sensor is usually mounted in the intake manifold so the tip will be exposed to air entering the engine. On engines that use mass airflow (MAF) sensors to monitor the volume of air entering the engine, the MAP sensor will also have an air temperature sensor built into it.
