Programming Question.

[PrivateJoker64]

Hate to be a pest, but does this program look OK?
See any problems?

If TIME > 08:00 then LT1 * ON
If TIME > 22:00 then LT1 * OFF
If TIME > 08:15 then LT2 * ON
If TIME > 22:30 then LT2 * OFF
If TIME > 16:00 then LT3 * ON
If TEMP > 82.5 then LT3 * OFF
MAX CHANGE 030 M then LT3 * OFF
If TIME > 21:00 then LT3 * OFF
If TIME > 22:00 then LT4 * ON
If TIME > 08:30 then LT4 * OFF
If TEMP < 80.4 then HT1 * ON
If TEMP < 80.4 then HT2 * ON
If TEMP > 80.8 then HT1 * OFF
If TEMP > 80.8 then HT2 * OFF
If TIME > 08:00 then FN1 * ON
If TIME > 22:45 then FN1 * OFF
If TEMP > 81.2 then FN2 * ON
If TEMP < 80.9 then FN2 * OFF
If TEMP > 81.4 then FN3 * ON
If TEMP < 80.9 then FN3 * OFF
If FEED CYCLE then RET * OFF
If FEED CYCLE then LOP * OFF


LT1 = Light One, MH
LT2 = Light Two, MH
LT3 = Light Three, MH
LT4 = Light Four, Refugium
HT1 = Heater One
HT2 = Heater Two
FN1 = Canopy Fan One
FN2 = Canopy Fan Two
FN3 = Sump Fan
PHS = Powerheads
LOP = Closed Loop
RET = Return Pump from Sump

Thanks!

You need default on statements for RET and LOP. The last four lines should be:

If Time > 00:00 Then RET ON
If FEED CYCLE then RET * OFF
If Time > 00:00 Then LOP ON
If FEED CYCLE then LOP * OFF
