Knob Mechanical Underfloor Heating Thermostat-HTW-21-23 Series
If you are looking for one of the best customized knob mechanical underfloor heating thermostat-htw-21-23 series manufacturers and suppliers,Website:, or a professional factory, Hotowell International is always at your service.??>> General??Knob Mechanical Underfloor Heating Thermostat-HTW-21-23 Series?are the international universal heating electronic thermostat. It use installation of direct wall and have a wide range of controlling temperature. Fool type control interface is easy to use. LED indicates the working state and it is easy for users to understand operation of the thermostat. It is applicable to the heating system of the temperature automatic controlling and provides users with a comfortable, safe, energy-saving and high standard heating environment.Access to external sensors can realize double temperature double controlling (Built-in sensor measures temperature and external sensor makes the over-temperature protection).>>Features ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ???16A?3600W Large load??Double temperature double controlling??Easy to use and cheapest>>Technical parameters?Voltage: 230VAC 50/60Hz?Power waste: <2VA?Range of temperature:?5?C-40?C?Ambient temperature:?-5?C-50?C?Protective casing: IP20?External sensor: B=3380 10K@25?C?Lead length:3M?Temperature protection??Shell material: Flame-retardant PC?Installation height:1.2M?Installation location:To be fitted in the surrounding air to flow freely on the wall, shall not be affected by other heat effect(Such as sunlight, windows and doors airflow and wall temperature).External limiting temperature sensor installation:The casing is buried under the floor, the sensor is arranged inside the casing, ending of casing should be thickened, and put in upper part of the concrete layer. Sensor cable can be instead of other cable to be lengthened to 50 meters. If the extension cable is used two of multi core cable, the rest of the cable can not be used for other equipment power supply (such as heating power cable) so as to avoid the voltage signal to disturb the thermostat. If the extension cable is shielded cable, shielding line should not be grounding. The best way is using independent extension cable and be arranged in a separate casing.Temperature setting and control:Adjust dial to the temperature which need to be controlled, the controller will automatically track and compare the current environment temperature with the setting temperature. When the environment temperature is higher than the preset temperature, the thermostat will automatically disconnect the heater. When the environment temperature in the current is lower than the setting temperature, the thermostat can automatically connect with the heater.Temperature calibration:Every thermostat in the factory is calibrated, the user don?t need to calibrate again. If the users need calibrating again, he can unload the thermostat knob. After room temperature is stable, use a thermometer to measure the accurate room temperature, and then anti-clockwise rotate adjusting rod slowly to green light state, keep scale indicating " |" which in on the panel and the corresponding disk temperature value aligned with the pressure regulating disk (please keep disk temperature value and Measured value of thermometer aligned.)>>Dimension (mm) ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?Dimension(mm)>>FAQQ1:What is the unit price?A.:The unit price varies according to different specific requirements, we are more than pleased to quote you the best price onceget your specific application. e.g. W/O Modbus, W/O key-card, 2/4 pipe system, W/O customized programming...Anyway, we are always ready to discuss details with you via Email.Q2:What is the MOQ, small quantities accetaple?A.: Commonly the MOQ for us is 500pcs, however, we also accept small quantities or Sample orders as starting.Q3:How is your products' quality and warrenty?A.:All of our products meet EU standards, samples are available for quality evaluation; all products are with 18 months warrenty.Q4:Can I print my logo on the products, and customize my own designed packing?A.:100% YES, but the order quantity shall be over MOQ, or else, extra costs will be charged.Q5:Do you supply OEM or ODM??A.:Yes, we have strong R&D sources and production ability, and already helping many international companies OEM/ODM cases?with highly positive feedback.Q6:Why should I buy products from your company?A.:That's really a good question, Quality Products but with Competitive Price,?Timely Delivery,?Professional and Fast Reacton, ...In a word, WE ARE DIFFERENT, why not just try from the Email...
