mechanical thermostat review held high indoor temperature and set temperature high resolution, operating fan coil fan and electric fire water valve, to improve the indoor temperature is high, the happy resource conservation goals. To adapt to the two pipe lines to/four disciplines, two/three electric valve, three-speed fan coil operation. With RS485 interface (online road FC270C have only) To access the building automation system. Widely used as a high-level office buildings, star hotels, clubs, airports, high-speed, venues, housing, etc.
electric water heater mechanical thermostat made deep contact, copper pieces of metal from copper to heat cold so in high temperature not particularly sensitive to the specified value of the time, the shape of a copper sheet metal is curly, now it is closed on contact. Water when the water is heating temperature to the provisions of the high thermal effect leads to mechanical thermostat copper in the copper from the heated above straight will contact bounce off power into the situation. In high temperature drop time copper recovery to the original situation make contact again connected into electric heat situation. 。
mechanical thermostat, it is also a hold with external mechanical thermostat has a bimetallic strip new products. Mechanical thermostat main purpose is for each electric heating supplies too hot hot spells, which are held in common and thermal fuse in use. Mechanical thermostat is used as the major overhaul, thermal fuse in mechanical thermostat failure when used as a secondary repair, powerful agent, each other to avoid damage electric heating element, and thus contribute to the fire.
first of all, the power cord to the sensing line and fire fan line well connected with mechanical hvac thermostat, and current research: if the three-phase reflect basic average temperature is high, there is no fault alarm overtemperature alarm lamp and together trip indicator light down, with his hand touched a panel or active button manually, if fire fan indicator, fire fan should be at the moment fluctuation affects manual or active button again, fan indicator, fire fire fan should interrupt working at the moment, the basic mechanical thermostat respectively the lessons.
