air-conditioner thermostat(fan coil thermostat,digital thermostat, raditator thermostat, floor heating thermostat) Introduction The TKB50...thermostat acquires the room temperature with its built-in NTC sensor. The heating contact will close when the room temperature falls below the selected setpoint in heating mode. The cooling contact will close when the room temperature exceeds the selected setpoint in cooling mode. Application In conjunction with fans and valves, TKB50… is designed to control the valve in heating or cooling systems to maintain the desired setpoint temperature in Commercial buildings, Residential buildings, Light industrial buildings… Features LCD display with backlight On/off control output for valve actuators Manual changeover of heating/cooling Timing function for thermostat switch-onswitch-off Minimum and Maximum setpoint limitation Symbol for valve indication “Key-lock” function for setted parameters protection Inclined design for better reading-out “fan-valve dependent control”or“fan-valve independent control”mode With an potential-free output Remote control type (TKB50.42LR) Technical data Voltage : AC230V (AC110V/AC24V available) Load : 3A Power consumption : 2W Setting range : 4 45 (factory setting: 5 35) Switching differential : ±0.5K Ambient temperature : -5 50 Protective housing : IP20 Housing material : self-extinguishing PCSelection tableModelFan controlSystem controlBacklightApplicationTKB50.42LAuto, Low, Mid, Hi Heating, OFF, CoolingYes2-pipe FCU systemTKB50.42LKAuto, Low, Mid, HiHeating/CoolingYes2-pipe FCU systemTKB50.42LRAuto, Low, Mid, HiHeating/CoolingYes2-pipe FCU systemTKB50.50LAuto, Low, Mid, HiHeating/CoolingYes4-pipe FCU system Pls contact us for more detail information.
