Metasys UNT Series User Manual

32 UNT Controller—Unitary Controller (UNT)
On the UNT140/141 series controller, terminals labeled RTN (Return) are
associated with the binary outputs, and a jumper block sets high side or
low side switching. Setting the jumper block to Low Side BO sets the
RTN terminals to 24 VAC. Setting the jumper block to High Side BO sets
the RTN terminals to common.
The UNT101, UNT111, UNT121, and UNT141 controllers have
two analog outputs. The load connects between the analog output and
analog output common terminals. Each output generates a proportional
voltage output of 0 to 10 VDC to common. The maximum load for each
output is 10 mA with a minimum 1000-ohm load resistance.
The Zone Bus provides UNT connections for M100C series actuators,
CBLPRO (for HVAC PRO for Windows commissioning), and the Zone
Terminal (ZT). The Zone Bus is available for connection at the Zone
Temperature Sensor, Zone Humidity Sensor, M100C series actuators,
UNT Controller Board, and CBLPRO.
