Santana air conditioning pressure switch is the four lines that then
Two green single-wire connection is the drying tank low-voltage switch, a two P three-wire plug connected to the high-voltage switch, two green single line is from the ambient temperature switch over, the other is from the low-voltage switch to the electromagnetic clutch, The control of the fan
Is not dry on the green color of the bottle is 1 air conditioning relay output line 2 is to the compressor power cord red 1 is an output line 2 is the cooling fan relay control line
On the dry bottle, the green color is 1, the air conditioner relay output line 2, is to the compressor power cord, red 1 is the output line, 2 is the cooling fan relay control line;
Two high voltage switch two low voltage switch, high pressure control fan, low pressure control compressor, low pressure normally closed high pressure normally open;
Pressure switch is the air conditioning above the double pressure switch, installed in the air conditioning on the high-pressure pipeline;
Some models are equipped with two pressure switches, respectively, high-voltage switch and low-voltage switch, double pressure switch is equal to the two pressure switch integrated a switch, the role of high-voltage switch is too high pressure disconnect circuit protection compressor and Air Conditioning System. The role of low-voltage switch is when the pressure is too low or when the lack of refrigerant circuit breaker to open the compressor;
Double pressure switch in the four lines are two high-voltage switch line, the remaining two are low-voltage switch line, four lines are generally two colors;
To determine the pressure switch failure first use the air conditioning pressure gauge to measure the system pressure, the general failure is the system pressure normal compressor does not work, first check the compressor insurance and pressure switch is not power, there may be some failure is too high or too low pressure Can not disconnect the circuit in time to play a protective function, this failure is unlikely.
