Here is Part 1 of our series Selectra Series 14 Circuit Analysis: Temperature Dial Testing.
This 5‑part series will cover temperature dial testing, discharge air temperature sensor testing, Selectra regulator and modulator/regulator testing, T115 room override stat testing, and sensitivity dial testing.
Maxitrol’s Selectra Series 14 electronic gas flame modulation systems are designed for direct fired make-up air heating equipment. OEM or retrofit applications include environmental climate control as well as industrial or commercial heating processes. Basic Series 14 components include an amplifier, an integral or remote temperature dial, a discharge air temperature sensor, and a mixing tube.
Series 14 works with Maxitrol’s modulator or modulator-regulator valves M411, M511, M611, and MR212(D, E, G, or J). The Selectra system’s unique electronic modulator or modulator-regulator valves control gas flow with instantaneous response and continual adjustment to maintain constant discharge air temperature.
