Electronic Temperature Control of a Damper or Valve Actuator
The Tempro electronic temperature controller uses an NTC sensor to read the ambient air temperature of the air handling unit. When the temperature rises, the controller signals the output device to open the damper, allowing airflow to cool the zone. This process is similar to controlling a solenoid valve or an actuated ball valve in fluid or air applications. If fluid is involved, the NTC sensor drops into a thermowell located on the tank, and the controller wires to the valve. The valve opens and closes based on the temperature controller’s reading.

Precision of Electronic Temperature Controllers
Electronic temperature controllers offer more precision compared to mechanical controllers. Mechanical temperature controllers typically have a wider tolerance (~5°F), while electronic controllers have a tolerance of 1°F, making them a more precise solution. Additionally, mechanical units have a tighter differential (12°F), causing the damper or valve to return to its normal state sooner than electronic controllers, which can have a differential of up to 30°F.
