4. Fuction

. Cool/Heat/Ventilation/sleeping, programmable Change Control  . Clock (Optional)

. or selectable indicator.          

. Manual/Auto Fan Speed

  Auto Fan: Adjust the setting Temp automatically accroding to the Temp difference between set-point and room Temp.

. Detect and Display Room Temperature

. Timing on/off function: Setting Turn on/off within 12hours at your pre-setting time.

. Ventilation model (the fan will be running, the motorized valve be closed)

. Low temperature protection : auto start at temperature below 5, prevent frostbite.

. Circulatingmodel the thermostat usually start to work  from 8:30 am to 5:30 pm at a week, from 9:00 am to 6:00 pm at the weekends, the set-point is fixed.

. Memory mode to reset to previous conditions. (Optional).

If the power occurs to be cut off suddenly, the thermostats could be continuing to work by order if the power returns. The function is popular at Hotel, System House etc.

. Sleeping modelAdjust the setting Temp automatically accroding to the thermal environment conditions..In order to save energy, in cooling fuction, the room thermostat will work at 25C although you set-point is 24C, meanwhile, in heating fuction, the room thermostat will work at 28C if you set-point is 29C.
