BT-901/902 series electronic controller can provide alone to control the temperature of heating or coolingapplication. The controller generates an incremented output signal. It is designed for adjusting the AC24Vreversible motor. When the load changes in a controlled environment, the proportional plus integral way to respond, so as to control the environmental temperature effect.

T202X Mainly used for central air conditioning heating and cooling system of T2021 series proportional integralcontroller; by detecting the environment temperature is compared with the set value, generates a control signal,automatically adjust the water valve opening, achieve energy balance of supply and demand, at the same time,start, stop state control of wind turbine.
