what causes an "UNK" status

[jimsflies]

Just noticed that my heater status is showing up as unknown. I'm still working on the program so maybe I have the programming, so maybe I have a conflict or something? Any idea why it shows as "unk"? Here is my program:

RT1#-A01; return pump main tank
CL1#-A02; slosed loop
RT2#-A03; return pump frag tank
SKM#-A04; skimmer
HE2%-A06; heater main tank (not controlled via ACIII right now)
CL2#-A07; closed loop frag tank
ALM&-A08; alarm?
MH1$-B01; halide main tank
PC1$-B02; 03 actinic main tank
PC2$-B08; blue actinic main tank
MH2$-B03; halide frag tank
HET%-B04; heater in sump
FUG$-B05; fuge light
FAN&-B06; sump fan
MON$-B07; moon lights

If Time > 00:00 Then ALM OFF
If Time > 00:00 Then SKM ON
If Time > 00:00 Then RT1 ON
If Time > 00:00 Then RT2 ON
If Time > 00:00 Then CL1 ON
If Time > 00:00 Then CL2 ON

If Time > 06:00 Then MH1 ON
If Time > 09:00 Then MH1 OFF
If Time > 09:00 Then MH2 ON
If Time > 21:00 Then MH2 OFF
If Time > 06:10 Then PC1 ON
If Time > 23:00 Then PC1 OFF
If Time > 06:10 Then PC2 ON
If Time > 23:10 Then PC2 OFF
If Time > 16:30 Then MH1 ON
If Time > 21:45 Then MH1 OFF
If Time > 21:45 Then FUG ON
If Time > 06:00 Then FUG OFF
If Time > 06:10 Then MON OFF
If Time > 23:00 Then MON ON
If Temp < 81.5 Then HET ON
If Temp > 81.8 Then HET OFF
If Temp > 82.0 Then FAN ON
If Temp < 81.8 Then FAN OFF
If Temp > 82.0 Then FUG OFF
If Temp < 78.0 Then ALM ON
If Temp > 85.0 Then ALM ON
If Temp > 84.0 Then MH1 OFF
If Temp < 50.0 Then HET OFF
Max Change 020 M Then MH1 ON
If Feed cycle Then RT1 OFF
If Feed cycle Then RT2 OFF
If Feed cycle Then SKM OFF
If Feed cycle Then HET OFF
If pH > 08.40 Then ALM ON
If pH < 07.95 Then ALM ON
If Power Fail Then ALM ON
If Power Fail Then CL1 OFF
Max Change 005 M Then CL1 ON
If Power Fail Then RT2 OFF
Max Change 001 M Then RT2 ON
If Power Fail Then SKM OFF
Max Change 012 M Then SKM ON
If Power Fail Then MH1 OFF
Max Change 015 M Then MH1 ON
If Power Fail Then MH2 OFF
Max Change 020 M Then MH2 ON
If Power Fail Then PC2 OFF
Max Change 010 M Then PC2 ON

unk shows up when none of the statements have been true since you added that statement or changed it. Once the parameter goes outside of that setting the status will then be known. Hope that makes sense.
