Field Connections - Field connections for accessory sensors and input devices are made the RTU-MP, at plugs J1, J2, J4, J5, J11 and J20. All field control wiring that connects to the RTU-MP must be routed through the raceway built into the corner post as shown in Fig. 37. The raceway provides the UL required clearance between high- and low-voltage wiring. Pass the control wires through the hole provided in the corner post, then feed the wires thorough the raceway to the RTU-MP. Connect to the wires to the removable Phoenix connectors and then reconnect the connectors to the board.

Space Temperature (SPT) Sensors

580J

A field-supplied Bryant space temperature sensor is

 

required with the RTU-MP to monitor space temperature.

 

There are 3 sensors available for this application:

 

 

S 33ZCT55SPT, space temperature sensor with override

 

button

 

S 33ZCT56SPT, space temperature sensor with override

 

button and setpoint adjustment

 

S 33ZCT59SPT, space temperature sensor with LCD

 

(liquid crystal display) screen, override button, and

 

setpoint adjustment

 

Use 20 gauge wire to connect the sensor to the controller.

 

The wire is suitable for distances of up to 500 ft. Use a

 

three-conductor shielded cable for the sensor and setpoint

 

adjustment connections. If the setpoint adjustment

 

(slidebar) is not required, then an unshielded, 18 or 20

 

gauge, two-conductor, twisted pair cable may be used.

 

Connect T-55

See Fig. 45 for typical T-55 internal connections. Connect the T-55 SEN terminals to RTU-MP J20-1 and J20-2. (See Fig. 46.)

EconoMi$er 2

The RTU-MP control is used with EconoMi$er2 (option or accessory) for outdoor air management. The damper position is controlled directly by the RTU-MP control; EconoMi$er 2 has no internal logic device.

Outdoor air management functions can be enhanced with field-installation of these accessory control devices:
