RTU--MP control system
The RTU--MP controller, see Fig. 43, 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 50TC*D
unit’s main control box, to the right of the CTB. See
Fig. 44. 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 9, RTU--MP Controller Inputs and Outputs
for locations of all connections to the RTU--MP board.
