Viewport ID String
In Viewport, the thermostats output a string of characters that describe the setup and
configuration of the thermostat. Refer to the following table for an explanation of
this string. Each element of the setup string is separated by a period. The following
are two examples of ID strings:
2A: CHV-THSTAT [v1.0] (HP.H2.C2.HA3.CA3.ADB2.H,Abp0,90.AX.F.L5.OS0.DA.UUDDUU)
2B: CHV-THSTAT [v1.0] (H/C.H1.C1.HA3.CA3.ADB2.FA.F.L5.OS0.DA.UUOOOO)
