ViewStat Communicating Thermostat
Connecting to a NetLinx Control System
To connect a single ViewStat to a NetLinx control system, use ICSNet cabling to connect the
RJ-45 jack on the ViewStat to any available ICSNet jack on the NetLinx Master. The maximum
cabling distance between the ViewStat and Master is 1,000 ft (304.8 m).
To connect multiple ViewStats to a NetLinx system, use a NetLinx Hub (NXC-NH) to add additional
ICSNet ports to the system, connect the RJ-45 jack on the ViewStat to an available ICSNet jack on
the Hub.
Connecting to a Landmark Control System
To connect a single ViewStat to a Landmark control system, use PhastLink cabling to connect the
RJ-45 jack on the ViewStat to any available PhastLink jack on the Landmark Master (MCU). The
maximum cabling distance between the ViewStat and MCU is 1,000 ft (304.8 m).
To connect multiple ViewStats to a Landmark system, use a Landmark Hub (PLH-RPT) to add
additional PhastLink ports to the system, connect the RJ-45 jack on the ViewStat to an available
PhastLink jack on the Hub.
Connecting the ViewStat to the HVAC System
Before connecting the ViewStat to the HVAC system, install the 24 VAC Suppression Ferrite, to
eliminate any potential noise problems.
Installing the 24 VAC Suppression Ferrite
Before connecting the 24 VAC power supply cable to the HVAC system, install the 24 VAC
Suppression Ferrite (provided), as described below (no tools required):
1. Pass the 24 VAC power cable through the ferrite bead once.
2. Loop the cord around, and pass it through the ferrite bead once more.
3. Gently remove any excess slack in the cable, and you’re done.
