1. The Rittal air conditioner does not start when it is turned on, and the A17 is faulty.
Check that the power supply voltage is 220V, normal; Detect that the battery voltage of the remote control is 3V, which is normal; Measure the fuse resistance value of the air conditioner compressor with a multimeter as infinity, which is normal.
2. The Rittal air conditioner does not start when it is turned on, the A17 fault is displayed, and there is no remote control function. Check that the remote control battery level is less than 1 bar and cannot be used (in this case, it will not be able to use it after replacing the new battery).
3. The Rittal air conditioner can be started when it is turned on, but the refrigeration effect is not good. Check whether the temperature sensor of the outdoor unit is damaged or in poor contact; Whether the four-way valve coil of the outdoor unit is burned out (can be measured with a multimeter), if it is abnormal, replace the four-way valve coil of the outdoor unit or repair the four-way valve coil of the outdoor unit.
4. During the operation of the Rittal air conditioner, the indoor fan has been running at high speed and the noise is loud (under normal circumstances, the indoor fan will automatically stop running and hum after the air is closed). Check whether the indoor fan motor is working normally and whether the fan belt is loose or broken. (The outer cover can be removed for observation)
5. Abnormal shutdown of the air-conditioning host of Rittal is as follows:
(1) The indicator light flashes or does not light up after the host is powered on:
(2) The main engine suddenly stops after running for a period of time
(3) Shutdown occurs after a few minutes of heating operation
(4) There is a crash during heating
(5) No refrigeration caused by other reasons
6. If none of the above problems can be ruled out, it may be due to the problem that the machine is not refrigerated or the heating effect is poor due to the error of the motherboard control program. Please repair after sale! The solution is as follows: first uninstall all hardware devices in the Start → Control Panel → Add → Remove Hardware from the Control Panel on the computer and then reinstall it again.
7. If the host cannot be used normally due to improper installation, you can find a master to provide door-to-door service to help you solve the problem.
