1. General
Usually, there are 7 wires available in heat pump digital thermostat, R an C 2 wires are for 24vac power supply. Sometimes, you might see Rc or Rh instead of R. Smart IoT thermostat is more and more popular in home application for AC control. Some reasons for high pressure protection of compressor:
1) The ambient temperature is too high
When the external environment reaches a high temperature of 43 degrees, the air conditioner will have difficulty dissipating heat during heating. At this time, the air conditioner will have high-pressure protection. When the outdoor temperature is higher than 43 degrees, the air conditioner is difficult to work. You can only temporarily do not turn on the air conditioner.
2) Abnormality in the control loop
When the control loop inside the air conditioner fails, the inside of the air conditioner cannot work normally, causing the internal pressure to increase, and protection will also occur at this time. Check where there is a problem with the control circuit and replace the corresponding parts to solve the problem.
3) other reasons:
The external machine is installed in an environment with poor heat dissipation, such as narrow staircases, behind billboards, inside grilles, etc.
