View Full Version : Heater program issue

Is this Program ok for the Apex using the season tables for heater. I also want the tank above 77.5 at all times. My only concern is if it drops below 77.5 will it stay on until it hits 85? If so is there a way to shut it off at say 78? unless the season table is a hotter temp then 78 then follow season table? My heater has a backup digital thermometer on it that is set to shut off heater at 79 as a backup. Only reason I follow season table is my tank heats up on the same schedule as that table in summer.

Fallback ON
Set ON
If Temp < RT+0.0 Then ON
If Temp > RT+0.5 Then OFF
If Temp < 77.5 Then ON
If Temp > 85.0 Then OFF

With the Apex the last rue code wins So if the RT is 79 you are good to go but if the RT is 76 then the third line of the code becomes true and the heater would be on.
