Versatiled Series PI Control Thermostat

Verstiled series is a big family which is suitable for most kinds of heating and air-conditioning terminal control or equipment control. PI Control models in this series are suitable for precise environmental temperature control. It regulates valve outputs by using proportional-integral algorithm. The 0-10V output signal can be used to control various electric modulating valves in fancoil unit, fresh air unit, air handling unit, and heat exchanger. With RS-485 interface it can be integrated by BA System via Modbus-RTU protocol.
