Thermostat Switch/Fan Coil Thermostat/LCD Thermostat 1. Product Summary S400 series ofLCD thermostats adopt PI and control way to avoid the overshoot and imbalance of the environment temperature at the setting values , also avoid the frequent movements caused by the adjustments of device. S400 series ofroom thermostats are usually applied to control 2-pipe and 3-speed fan coil and motorized valves, and control 4-pipe and 3-speed fan coil and motorized valves in the business, industrial and civil constructions. 2. Technical Parameter Working Voltage: 220VAC,50Hz/60Hz Room Temperature: Controlling Range 15 35oC Relay Output: Terminal Current 3A/250V Power Consumption: 3W Sensing Element: NTC Resistance Temperature Controlling Precision: ±1oC Storing Environment: Temperature( -20 70), Relative Humidity (RH<92%) Working Environment: -5 ºC 50 ºC Surface Material: White PC engineer plastic External Dimension: 86* 86* 40(mm) Installation: Standard 86 Junction Box 3. Characteristion Big LCD display, English language, clearly display the working mode; With blue backlight, soft and comfortable. Display room temperature, clock and week at the same time. Menu type of program, easy and fast to be manipulated. 5 working days per week, saturday and sunday, can be set 4 time segments at most each day, the progamming data of each working mode is mutually independent, the beginning time of each period is without sequence. With the function of room temperature adjustment, the adjustive range is ±10. Remember the parameter for ever after power off, and can carry out backup function by progamming. Press composite key to lock (unlock) keys. Press composite key to recover the default values. Display symbols of keylock and the condition of fan. Can control 3-speed fan (220VAC), SPDT/SPST motorized valves and electromagnetic valve. Press one key to set 3-speed fan coil and auto working mode, can set the fan under control by progamming(Turn on/off the fan coil according to the condition of valve). 4.
