General Purpose Controller
Auxiliary building control for lighting, fans, pumps and other HVAC equipment
The Universal Controller provides auxiliary building control to interface with lighting, fans, pumps and other HVAC equipment in a stand-alone or Carrier networked environment using closed loop, direct digital controls. The Universal Controller's pre-engineered algorithms provide simple building integration for small-to-medium commercial applications with 16 field point capability (8 inputs and 8 outputs).
General
-
Integrates auxiliary building system control
-
Controls non-Carrier equipment and Carrier HVAC equipment not equipped with Product Integrated Controls, using the Carrier communicating network
-
Compatible with all standard Carrier network user interfaces
-
Stand-alone control and monitoring of up to 16 field points, using proven algorithms
-
Two LEDs, conveniently located on the front of the module, indicate processor status (red) and communication bus status (yellow)
-
Local connection for Carrier network
-
Total facilities management when linked to a Carrier network
-
Three-day backup of clock and data such as Runtime and Consumable
-
Batteries are not required
-
Uses any standard, field-supplied 24 vac, 60 va transformer

8 Outputs
-
Each output (1 to 8) can be discrete or analog
-
Discrete outputs are 24 vdc at 80 mA
-
Analog outputs are 4 to 20 mA or 0 to 10 vdc (varies with point type)
Carrier Network Features
-
