3. Fasten the base to the wall with the supplied screws.
4. Seal wire entry using caulk, drywall putty or insulation.
Connecting the ViewStat to AMX Control Systems
When a Mini Verter is used the Viewstat has a single RJ-45 jack on the rear panel, and uses ICSNet cabling to
connect to NetLinx or Landmark control systems.
The wires should be connected in the standard manner described in the following table. If standard EIA/TIA
568A/B color coding is followed, wiring problems will be minimized.
Minimize wire entry hole size and seal – drafts from inside the wall could affect
temperature readings.
Loss of internal programs may result from static discharge to thermostat circuit board.
Installer must touch a grounded metal object before handling the circuit board.
The terms "PhastLink" and ICSNet" are essentially interchangeable within the
context of cabling/connectors. They both use a standard 10BaseT type connection
(i.e. Category 5 wire and RJ-45 connectors), and they share the same pinout
information for the RJ-45 jacks. Generally the term "PhastLink" is used when dealing
with Landmark, and "ICSNet" is used when describing NetLinx control systems.
