Works, but lacks refinement

      Comments about Venstar Add-A-Wireless Thermostat - T1119RF:

      This product meets my need of a wireless portable thermostat for an upstairs room, but it lacks refinement.

      My main areas of complainant are:

      1) Confusing controls, this unit could really use a couple more buttons to make setting the unit more intuitive.

      2) No obvious indicator that the wireless unit has control of the HVAC system.

      3) Lack of wireless strength indicator, while the 415 MHz communication frequency probably does a good job of reaching most parts of a standard size house, I think it is unforgivable that there is no way to see the connection strength.
