Reference No.:
1/ 4
T8000 touch screen thermostats are designed to control heating, cooling, or
year round air conditioning unit in commercial, industrial and residential
installation. Typical applications include the control of fan coil units, packaged
terminal air conditioners and combination of heating and cooling equipment.

speed line voltage fan.
T8000 touch screen thermostat is applicable to the two-in-one system of
central air-conditioner and floor heating. In summer, comfortable environment
is reached by controlling the fan coil of air conditioning system with local
temperature. In winter, warm air from air-conditioner and floor heating is
available for quick heating.
T8000 features with microcomputer control, large LCD screen display, and displays the status of work mode
(cooling/floor heating/heating/floor heating & heating/air venting), fan speed, indoor temperature and set
temperature etc.. Capacitance touch screen enhances the fluency on operation. Keypad includes: Power on/off ,
Mode selection (M), Fan Speed selection , Clock/Timer and two Adjustment buttons (∧&∨).
