Modulating digital thermostat AEK-7000 are designed to provide Proportional-Integral(PI) modulating control in 2-pipe or 4-pipe

Modulating digital thermostat AEK-7000 are designed to provide Proportional-Integral(PI) modulating control in 2-pipe or 4-pipe fan coil units, zoned commercial heating, ventilation and various heating and cooling applications.

AEK-7000 includes energy savings card key input, auto-detection of temperature sensor (remote sensor or internal sensor), and optional Celsius or Fahrenheit operation. Permanent user setting and program setting retention during power loss.
