applications with extreme winds could require
mounting the sensor in an area less affected by wind.
BAYSENS021* Setpoint Input
This chart lists setpoint /voltage/resistance for the VAV
supply air cooling setpoint on the RTRM module. The
chart can be used for troubleshooting units that have a
remote setpoint at this input.
The typical remote setpoint input device is a
BAYSENS021* zone sensor.
The connection points are RTRM J6-2 and RTRM J6-3.
If a remote setpoint is used, clip jumper R69 on the
RTAM module. If the jumper is not clipped, the unit will
ignore the RTRM setpoint.
N No otte e:: A remote setpoint can also be applied to the
RTAM supply air cooling setpoint input.
However, the RTAM inputs use different
temperature/ resistance inputs. See VAV setpoint
inputs for input values.

This chart lists setpoint/voltage/resistance for VAV
setpoints on the RTAM module in the control
compartment. The chart can be used for
troubleshooting the RTAM module or for applying a
remote setpoint to the unit.
Each setpoint can be provided remotely by applying
the appropriate resistance as shown in the table after
cutting the resistor next to the setpoint knob. See
Table
105, p. 168 .
