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

Controller incorporates temperature management, defrost management, evaporator fan
management, and alarm management control functions.
