Using ZS Sensor or an Equipment Touch
The ZS sensors or Equipment Touch™ will connect to the
UPC via the UPC's RNET connector. Be sure to follow the ZS
sensor and Equipment touch installation instructions available
for the specific devices being used. If the ZS sensor will pro
-
vide space temperature feedback for equipment operation, then
the control mode to best use for the equipment is space tem
-
perature multi-stage.
Otherwise, be aware of the differences in mode trip of the roof
-
top product vs. the displayed set point microblock. If use link
-
age is set to Yes in the UPC, then the ZS sensor values will
only be displayed in the Linkage values shared between the
UPC and the RTU. When set to No, the SPT of the RTU will be
forced and the set point microblock and the RTU's Occupied
and Unoccupied set points will be shared values.
