Discharge Air Temperature Sensor (120° to 170°F)

These air temperature sensors maintain precise, stable gas-fired temperatures. Selectra's unique electronic Modulator or Modulator-Regulator valves control gas flow with instantaneous response and continual adjustment. They are the superior alternative to mod motors and butterfly valves. Amplifiers are available with optional features such as adjustable low-fire start duration, and with integral or remote temperature selection.
