Fan coil thermostat wiring should pay attention to the installation of two big problem
fan coil thermostat wiring should pay attention to the installation of two big questions:
the first: first of all you have to know you this fan coil LCD thermostat to control what equipment.
the second: figure out how much these devices need to pick up line, every line where took it. Of course the general control fan coil fan coil LCD thermostat is 7 wire is given priority to, From fan coil terminal need to pick up 4 with line, this 4 with line were high, medium, low and zero line, plus installed on the fan coil of the three wires of electric valve is open valve line respectively, close the valve line and zero line. The seven lines respectively with fan coil LCD thermostat terminals) 。 Another is fan coil wire, introduced in the LCD thermostat and the zero line, the two wires that will see you from that pick up the free control, as long as connected to 220 v power supply.
there is a kind of fan coil units LCD hvac thermostat that is floor heating thermostat, the fan coil LCD hvac thermostat is used to control equipment such as electric blanket, geothermal film of floor heating floor heating products, such as the fan coil hvac thermostat is 6 wire, respectively by two line of floor heating equipment, external sensors, as well as the power cord.
fan-coil unit is mainly composed of low noise motor, impeller and heat exchange coil, etc. Fan coil is an ideal product, at the end of the central air conditioning fan coil units are widely used in hotels, office buildings, hospitals, residential and commercial, scientific research institutions.
To that end, Zhuhai Edison Smart Home Co., Ltd. has successfully built a solid foundation and infrastructure for motor operated valve manufacturing.
During Zhuhai Edison Smart Home Co., Ltd.’s existence in a market we didn’t receive any negative feedback from our customers.
Zhuhai Edison Smart Home Co., Ltd. sells ac compressor control valve and yet their focus on operational excellence and mastery of distributed manufacturing facilities hvac expansion valve has made them the dominant player in the space.
Zhuhai Edison Smart Home Co., Ltd.’s model also predicts (i) a positive effect of management on firm performance; (ii) a positive relationship between product market competition and average management quality (part of which stems from the larger covariance between management with firm size as competition strengthens); and (iii) a rise (fall) in the level (dispersion) of management with firm age.
