Important: Use the MR5 Series Panel Mount Case Controller only as an operating control. Where failure or malfunction of the MR5 Controller could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the MR5 Controller.
Important: Utiliser ce MR5 Series Panel Mount Case Control uniquement en tant que dispositif de contrôle de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du MR5 Régulateur risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du MR5 Régulateur.

The MR5 Series Panel Mount Case Controller controls compressor, evaporator fan, and defrost cycles to maintain the temperature of refrigerated units. The MR5 Controller facilitates a defrost cycle and uses time or temperature to control defrost termination. The MR5 Controller incorporates temperature management, defrost management, evaporator fan management, and alarm management control functions.

The communication adapter, part number ADPT-MR5-RS485, is an isolated RS485 adapter that you can use to interface with a Building Automation System (BAS). The communication adapter is included with the MR534AFDV models. It is not included with the MR534AFDN models, but you can purchase it separately to add BAS communication. See Table 2 in Ordering information.
