I have two 200w heaters. I had been running them individually with each one programmed to alternate every 4 hours. This worked great until we left for a couple days and the house was left unheated for a couple days and the heaters running individually could not keep up with the demand. I'm now trying to have them both turn on when 0.2 degrees below RT then have one turn off at 0.0 and the ther turn off at 0.2 degrees above RT. Heres my programming:
Heater 1
Fallback OFF
Set OFF
If Tmp < RT+-0.2 Then ON
If Tmp > RT+0.2 Then OFF
Min Time 002:00 Then OFF
Heater 2
Fallback OFF
Set OFF
If Tmp < RT+-0.2 Then ON
If Tmp > RT+0.0 Then OFF
Min Time 002:00 Then OFF
My problem is that both are turning on and off together.
Also, are there any safeguards that I should be thinking about incorporating?
