AMX_ViewStat NetLinx Module - Overview

The ViewStat Communicating Thermostat may be controlled from a NetLinx system using the AMX_ViewStat NetLinx module. This module requires ViewStats to be connected through an ICSNet interface.

The ViewStat module is designed to save you the work of manually coding the entire ViewStat command set. By using the module, you’ll save time, and still take full advantage of the ViewStat’s features. While it is strongly recommended that you use the NetLinx module, it is also possible to write your own code "from scratch".

For a detailed description of the NetLinx programming protocol for the ViewStat, refer to the "ViewStat Programming Protocol Reference Manual", available on the AMX.COM web site.

When connecting thermostats (thermostat/mini-verter pair), it is best to initialize each mini-verter separately. If all mini-verter devices have the same device number and are on the bus at the same time, an initialization problem can occur where all devices obtain the same new device identification number. This is different from the serial number of the thermostat that is set locally at the thermostat.

The ViewStat may be controlled from a NetLinx system using the AMX_ViewStat NetLinx module. This module requires ViewStats to be connected through an ICSNet interface. The number of thermostats is limited by the number of ICSNet devices that may be connected at one time to the master. The initialization sequence is shown below.
