ViewStat Communicating Thermostat

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.
