12. Read PDF Trane Voyager Fault Codes Trane Voyager Fault Codes 6. Especially when you have open cooling towers. Defrost fault condition (heat pumps only) 7. The chiller could also be overcharged with refrigerant, so you want to check your set points, temperatures and pressures around the system and then remove (recover) some of the excess refrigerant. Chiller Fault Finding. The services of a qualified technician should be employed through the medium of a maintenance contract with a reputable service company. Chillers are very expensive and they can be quite dangerous. Additionally high pressure discharge can occur when the return condenser water, on a water cooled chiller, is returning from the cooling tower too hot. Explanation: Error of condenser temperature sensor (Open/Short) Error code: 201. Now if you have a high pressure warning on the suction line, then three main things that can cause this. Also, make sure that you check with the manufacturer that it is capable of doing so before doing that. It’s slightly uncommon for this to happen, but it could have been knocked during maintenance etc. Check before you turn these back that they are meant to be switched on, and for any grounding faults.

However, if you’re unfamiliar with error codes for furnaces, then you may be unaware of what these codes mean. The unit will start in 3 minutes. We’re going to cover high pressure on the discharge, low pressure on the discharge, low pressure on the suction line, high pressure on the suction line, some general electrical issues you might come across as well as a few other issues. To protect the air conditioner upon immediate restart after a stop, the microcomputer controller will delay the unit for 3 minutes before the air Make checks on the chiller and listen for noises. You have to wait for it to cool down or adjust the parameters and the set points of the chiller.
