The T612DFH-4 and T612DFH-4+PIR Thermostat Controllers provide control of two- or four-pipe fan coils, cabinet unit heaters, or other equipment. These thermostat controllers provide on/off or floating control outputs and three speeds of fan control. TheT612DFH-4+PIR Thermostat Controller has occupancy sensing capability built into the device. These controllers are stand-alone devices that maximize up to 30% energy savings in high-energy usage light commercial buildings, such as schools and hotels, during occupied times by using additional standby setpoints. See the Occupancy Sensor Operation –T612DFH-4+PIR Thermostat Controller section for more information.

The T612 Thermostat Controllers provide the user access to parameters, such as system mode, fan mode, and temperature setpoints. Additionally, the T612 Thermostat Controllers have over 20 configurable parameters enabling the thermostat controllers to adapt to a variety of applications.

All T612 Thermostat Controllers use an intuitive, plain text, menu-driven backlit display that makes setup and operation quick and easy. The T612 Thermostat Controllers also employ a unique, Proportional-Integral (PI) time-proportioning algorithm that virtually eliminates temperature offset associated with traditional, differential-based thermostat controllers.

Important: The T612DFH-4 and T612DFH-4+PIR Thermostat Controllers are intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the controllers 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 controllers.
Important: Le T612DFH-4 and T612DFH-4+PIR Thermostat Controllers est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du controllers 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 controllers.
