Two major issues that should be paid attention to when installing and wiring fan coil thermostats

The fan coil unit has a compact structure, sturdiness and durability, and usually adopts high-quality galvanized sheet casing. The condensing surface-mounted air duct water pan is integrally formed by a molding process, and there are no welds, solder joints, and fire-proof insulation materials that are integrally connected to the water pan. . The drainage pipes and lines are easy to install, and the left and right connection and return air modes can be changed at any time to match the site conditions. The heat exchanger is reasonably matched, and the air volume can be adjusted in three gears, which saves the power consumption of the fan.

　　 The following two major issues should be paid attention to when installing and wiring the fan-coil LCD thermostat.

　　 1. First of all, you need to know what equipment your fan coil LCD thermostat controls.

　　 Second, figure out how many lines these devices need to be connected, and where each line is connected. Of course, the fan coil LCD thermostat that generally controls the fan coil is the 7-wire system (4 wires need to be connected from the fan coil terminal. These 4 wires are high, medium, low and zero wires respectively. In addition, the three wires of the electric valve installed on the fan coil are the valve opening wire, the valve closing wire, and the neutral wire. These seven wires correspond to the wiring terminals of the fan coil liquid crystal thermostat). The other is the live wire and the neutral wire introduced by the fan-coil liquid crystal thermostat. These two wires depend on where you connect them, and you can control them freely. Just connect the 220V power supply.

There is also a fan-coil liquid crystal thermostat, which is a floor heating thermostat. This fan-coil liquid crystal thermostat is used to control floor heating equipment such as electric blankets, geothermal films and other floor heating products. This fan coil thermostat is The 6-wire system has two control wires for ground heating equipment, an external sensor, and a power cord.

　　The fan coil unit is mainly composed of a low-noise motor, an impeller and a heat exchange coil. Fan coils are ideal end products for central air conditioning. Fan coils are widely used in hotels, office buildings, hospitals, commercial and residential, and scientific research institutions.
