RTU-MP Control System

RTU-MP Control System

The RTU-MP controller, see Fig. 47, provides expanded stand-alone operation of the HVAC system plus connection and control through communication with several Building Automation Systems (BAS) through popular third-party network systems. The available network systems are BACnet MP/TP, Modbus and Johnson J2. Communication with LonWorks is also possible by adding an accessory interface card to the RTU-MP. Selection of the communication protocol and baud rate are made at on-board DIP switches.

The RTU-MP control is factory-mounted in the 50HCQ unit’s main control box, to the left of the CTB. See Fig. 48. Factory wiring is completed through harnesses connected to the CTB. Field connections for RTU-MP sensors will be made at the Phoenix connectors on the RTU-MP board. The factory-installed RTU-MP control includes the supply-air temperature (SAT) sensor. The outdoor air temperature (OAT) sensor is included in the FIOP/accessory EconoMi$er2 package.

Refer to Table 8, RTU-MP Controller Inputs and Outputs for locations of all connections to the RTU-MP board.
