The on/off switch turns the everything on or off and does not effect the mode. When you push the o/o button it just turns the system on or off and does not change the last mode that was set.
Let's try to walk thru this...Let's assume the system is off..
Press o/o, the thermostat lights up and will tell you the status when it was last turned off...
Let's assume you want to cool in Zone 1 (I'm assuming you have a 2 zone, i.e. An ac in the bedroom?)
Press the zone button until zone 1 appears on the screen
Now press the mode button until cool shows on the screen
Now press the up/down arrow to set the temp
Press the fan button to set auto, hi, med or low..
Now the ac should start cooling if it is hotter than your set temp
If you push the off button the thermostat will go off and the ac will stop after a delay period.
If you push on the unit will come back on exactly where you just turned it on.
Your problem is the mode is set to auto and not cool or furnace. You can set it to off but the ac or furnace will not turn on until you set the mode for the one you need.
So with the mode you can select ac or heat or auto to automatically switch from cool,to heat if for instance a cold front thru and your unit was cooling but now needs to heat. I never use auto mode. I either select color or furnace or off. Off when I want to run just the fan on low,med or high.. hope this helps
