UNK state

[Giovanni]

Curt,

It seems that any device that has a range of control in the code is often reported as UNK on my ACIII. This includes the web access and the ACIII but not the ANs. My devices with ranges include the heater, Chiller, and Ozone. I can turn them on or off manualy then set them back to auto and the condition goes back to UNK. I have tried restarting the ACIII and sometimes this helps but eventually they go back to UNK. The ORP control seems to be UNK all the time unless it is in Auto ON with the others being more random, less freq. and only when they are in the auto off state. This fact is also reflected in the status log. Here is my code:

If Temp < 77.4 Then HTR ON
If Temp > 77.5 Then HTR OFF
If Temp > 77.6 Then CHL ON
If Temp < 77.5 Then CHL OFF
If ORP > 400 Then OZN OFF
If ORP < 385 Then OZN ON

Any sugestions?

The UNK state means that none of the program statements for a particular timer have evaluated as true since the last power cycle or program modification. For OZN it will occur if the ORP is between 385 and 400. For HTR it will occur if the temp is between 77.4 and 77.5. As soon temp or ORP goes above or below a setpoint the timer state will become known.
