Been experimenting (but not reading), and have a basic question; can the up/down buttons in the ISY99 interface do the same thing as the up/down buttons on the thermostat? On the thermo, I have programmed it to change set points during the day. The buttons on the thermo over-ride the set points, but only until the next programmed time comes around. Is this, or can this, be true for the ISY99? The ISY99 seems to set the set points "permanently".
