Dual Temperature Sensor (55° to 90°F)/(90° to 140°F)

Selectra Series 14 systems are designed primarily for make-up air heating, as components of direct fired equipment. 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.
