MCH1

MC6-CH1 model is programmable touch screen thermostat designed for fan coil unit or wind pipe system of central Air conditioner helps to adjust the indoor temperature by comparing the room temperature with the
setting temperature. The thermostat applies to water system or wind system (two pipes or four pipes) of air conditioner ,controls fan
coil,motorized valve, motorized ball valve or air valve to adjust room temperature,reaches the setting point and achieves the purpose of saving energy.

MCH2

There are two set points, Low and High, user could set two alerts : low and high set point ,when the CO2 lower than Low setting the CO2 font will be yellow color, when the CO2 higher than High setting the CO2 font will be red color , at the same time there will be alert message appears on the bottom line. If output is on there will be a alert message shows up; the message is Valve ON(CO2 mode) or Fan On(Fan mode). If the ambient sensor control is enabled there will be a alert message shows up, controller would be turned ON/OFF as the room brightness, if is dark it will be turned OFF auto, if bright it will be turned ON.

MCH3
