To wire ZS sensors to the controller
ZS Sensors are thermistor-based temperature sensors that may optionally sense humidity, CO
2
, or VOC. ZS
Sensors are wired to the Rnet port on i-Vu® Open controllers. You can use the following ZS sensors:
ZS Standard
ZS Plus
ZS Pro
ZS Pro-F
NOTES
The ZS CO2 model uses 190 mA during sample period. Use auxiliary 12 Vdc, unless it is the only device on
the Rnet port.
A control program can use no more than 5 ZS Sensors
SPT sensors cannot share the Rnet with other devices.
For detailed instructions, see the
ZS Sensor Installation Guide
