数字室调温器

room thermostat LCD thermostats, digital thermostat, electric heating thermostat; KTH203 digital room thermostat are used to control room temperature in commercial, industrial and residential environment via controlling fan coil units, motorized valve, motorized fan, heating pump and so on. It uses NTC to detect the room temperature and compares it with the set-point so as to automatically keep the room temperature stable. Its simple structure, reliable design & easy installation can satisfy users high demand of temperature. Technical Data. Power Supply: AC24V/AC110V/ AC210 230V, (optional) 50/60HZ Timing Error: <1% Control Performance: ON/OFF control Setting Unit: 1/step Electrical Rating : <1A0.6A Load Current: 3A Accuracy: ±1ºC Set-point Range: 0ºC - 40ºC Consumption: <1.5W Sensor: NTC Dimension: 86*86*38mm (H*W*D) Enclosure:Fire retardant PC ABS Communication Connection:RS485, M-bus(optional) Modulating Output:0-10 Vdc or 4-20mA(KTH203M); or 3-point Floating; KTH203Y (Optional) Features Luxury appearance with Large LCD display. Adjustable heating/cooling/ ventilating/sleeping mode control Adjustable manual 3-speed or automatic fan speed control and on/of control output for valve. Internal or external NTC sensor(optional) Real time display on LCD, real time clock with timer. If the showed time is not real time, users could press buttons under power off condition to change it. Thermostat mounted directly onto a wall or standard junction box. Reliable AC power supply by capacitor or power switch.(Optional) Hotel card-key control interface: changing into comfortable mode with putting in the card-key, and energy-saving mode with pulling out the card-key. (optional) Fuction Cool/Heat/Ventilation/sleeping Change Control Clock, real time display. or selectable indicator. Purple, Blue, Red backlight(Optional) 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) Temperature calibrations: Function when the tested temperature is not conforming to actual room temperature. . Low temperature protection : auto start at temperature below 5, prevent frostbite. Circulatingmodel thethermostat usually start to workfrom 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. 5+2 or 7 days 4 periods and customizing Programmable. (optional) Infrared remote control (optional)
