Fan coil temperature controller installation wiring should pay attention to which
Fan coil body structure is compact, strong and durable, usually using high quality galvanized sheet housing, condensing surface mounted air duct water plate using molding process integrated molding, no weld, welding spot, in line with the fire code insulation material connected to the water plate as a whole. The drain pipe and line are easy to install, and the way of right and left connection and return air can be changed at any time to match the site situation. The heat exchanger is matched reasonably and the air volume can be adjusted in three grades to save the most electricity for the fan.
Fan coil liquid crystal temperature controller in the installation wiring, should pay attention to the following two major problems.
First: first you need to know what you want to control the fan coil's liquid crystal thermostat.
Number two: figure out how many wires these devices need and where each wire comes from. Of course, the general control fan coil fan coil LCD temperature controller is the main system of 7 lines (from the fan coil terminal need to connect 4 with the line, the 4 with the line is high, medium, low and zero line, plus installed in the fan coil on the electric valve of the three lines are open valve line, valve line, zero line. The seven wires correspond to the terminals of the fan-coil liquid crystal temperature controller. The other is the fan coil LCD thermostat introduced by the wire and zero line, the two lines that will see you from the connection, free control, as long as the 220V power supply on the line.
There is also a fan coil LCD thermostat, that is floor heating thermostat, the fan coil LCD thermostat is used to control floor heating equipment such as electric blanket, geothermal film floor heating products, the fan coil thermostat is 6 line system, respectively connected to the floor heating equipment two control lines, external sensors, and power line.
Fan coil unit is mainly composed of low noise motor, impeller and heat exchange coil. Fan coil is the ideal end product of central air conditioning, fan coil is widely used in hotels, office buildings, hospitals, commercial and residential, scientific research institutions.
