status UNK ?

Why does the AC III display status UNK? instead of either on or off when checing it through the web server? Something in my program. I does it for the chiller and CO2 but not the heater. Seems like it displays when they are on ok but the UNK appears when they are off from what I can tell.

The UNK status simply means that none of the statements associated w/ that timer name have ever been true. After a program modification or power cycle the timer name states are reset to this UNK status. It is occurring for the chiller CO2 because the temperature or pH is between the high and low set points. As soon as the temp or Ph goes above or below a setpoint the timer will be in a defined on or off state.
