Coldguide: R/HVAC Error Codes

Roger Mirgard

About this app

ColdGuide is an independent offline field reference for refrigeration and HVAC technicians. Select a controller and search by code or keyword to find model-specific settings, alarms, error codes and setup information. Results are grouped by manufacturer and device because the same code can mean different things on different controllers.

The catalogue covers selected CAREL MPXPRO, MPXone and MasterCella; Danfoss AK-CC, AK-RC, EKC and ERC; Mitsubishi Electric CITY MULTI/VRF, Mr. Slim, Ecodan and PAC-IF; Daikin EKE controls and air-conditioner fault references; and Eliwell IDNext, IDPlus, RTX and Coldface. Browse parameter groups, documented ranges, factory values and option meanings where available. Supported models may also include wiring views and controller-access instructions.

Save useful references, star frequently used controllers and revisit recent searches. The catalogue is stored on your phone and works without an internet connection.

Coverage varies by model, hardware variant and source edition. Some controllers have only selected settings or alarms. ColdGuide does not connect to or control equipment. Always confirm the fitted model, firmware and current manufacturer instructions before changing settings or servicing equipment.

ColdGuide is provided by Frigopulse AB and is not affiliated with or endorsed by the equipment manufacturers.
