N320 Series Electronic Thermostats (Heating & Cooling)

The N320 series electronic thermostats provide dedicated temperature switching for cold rooms, heated holding tanks, and commercial refrigeration. With models featuring 1 relay (N321), 2 relays (N322), or 3 relays (N323), they drive compressors and electric heaters directly, with programmable start-up delays to protect compressors from rapid cycling.
