Summary of Contents

• Page 1: HY08AC Touch Screen Thermostat User Manual HY08AC fan coil units thermostat is used for control room temperature in central air conditioning fan coil units system. HY08AC uses microprogrammed control unit, large LCD display, and features such as working mode, fan speed, room temperature, setting temperature, and 7 days 4 period programming. In turn on state, press the key to decrease or increase temperature by 0.5°C. Long press the key for 3-5 seconds to enter into the setting screen for time setting. The technical data includes power supply, rated current, set point range, and ambient temperature. The protection class is IP30, and the housing is made of PC+ABS plastic. Timing turn on/off settings can be adjusted for both on and off states. The working mode can be switched between cooling, heating, and ventilation. In programmable mode, the temperature cannot be adjusted while working. The manual and programmable mode choice allows for different operational settings.
• Page 2: Valve control operates by opening the motorized valve when the room temperature is below the set temperature and closing it once the desired temperature is reached. The lowest limit for setting temperature is 5℃ and the highest limit is 35℃. The fan coil unit can be controlled in different modes, including ventilation mode where it is not under control. The key lock function disables operations after 10 minutes of inactivity, and can be unlocked by pressing a specific button for 5 seconds. The thermostat can enter energy-saving mode when a door card is pulled out, adjusting the temperature automatically based on the mode. Fault detection is indicated by error messages E1 and E2 for sensor issues, with temperature limits displaying HI for high and LO for low. The thermostat allows for programmable settings, enabling different temperatures at different times throughout the week. Installation guidelines specify that the thermostat should be mounted at a height of 1.5m and away from drafts or heat sources. Advanced settings can be accessed by long pressing a button, allowing for further customization of the thermostat's functions. The warranty period for the product is 18 months, with lifetime warranty options available under certain conditions.
