ZS Sensor

Applications Guide

Step 4: Add a BACnet Setpoint microblock

The BACnet Setpoint microblock allows you to define the setpoint adjustment functionality for a ZS sensor and

allows a ZS Pro or Pro-F to display setpoint values that can be edited from the sensor.

From the

Control

microblock menu, add a

BACnet Setpoint

microblock to determine how the user will

interact with the sensor's Setpoint Adjustment screen. Enter the following information in the Property Editor.

Enable Rnet

Check to allow this microblock to communicate its value(s) to and from a ZS

sensor.

Setpoint Adjust Limit (+/-)

The maximum amount (degrees) by which the user can adjust the zone's

setpoints from a zone sensor if an

Adjust setpoint offset

option is selected

under

Sensor Setpoint Adjust Option

Clear adjustment on transition

to unoccupied

ZS Pro and Pro-F sensors - Check to have the Setpoint microblock reset the

sensor's setpoint adjustment value to 0 each time the microblock's OCC

input changes to false (off) and leave it at 0 when the OCC input changes

again to true (on) or when the zone enters a timed local override condition.
If this field is not checked, the Setpoint microblock will not reset the sensor's

adjusted value for the next occupied period.
ZS Plus sensor - This field does not apply. The Setpoint microblock cannot

reset the sensor's adjusted value.

NOTE

The Setpoint microblock does not use adjusted values during

unoccupied periods.

Edit Increment

The amount (degrees) that the zone temperature setpoint is adjusted by

each press of a ZS Pro sensor's or button. For a ZS Plus sensor, slider

adjustments are read to the nearest increment.

Sensor Setpoint Adjust Option

Select how you want to see and adjust setpoints on a ZS sensor.

Disabled

Prevents editing the setpoints at the sensor.
