21win Posted July 18, 2009 Posted July 18, 2009 I have installed 5 Venstar 7Day programmable thermostats for control with ISY99 via Insteon. Generally working great. I turned them OFF and then ON via ISY, and now the thermostats display "OF" or "0F" (not sure if it is Oh-F or Zero-F) next to the Heat mode. I cannot seem to get rid of this. Ideas? Thank You, - Jon
nstein Posted July 18, 2009 Posted July 18, 2009 Try setting the set-point in ISY, it might be out of range. -Nick
