Below is my heater program.

If Temp < RT+-0.4 Then ON
If Temp > RT+0.0 Then OFF

I would like the heaters to be off while the halides are on, from 2-8pm.

Is this the desired program?

Fallback OFF
If Temp < RT+-0.4 Then ON
If Temp > RT+0.0 Then OFF
If Time 14:00 to 20:00 Then OFF

Just want to make sure. thanks.

That would work, but I think there's a better method - I suggest replacing

If Time 14:00 to 20:00 Then OFF

with

If Outlet MH_Lights = ON Then OFF

This way, if you change the times for your lighting, you won't have to modify the programming for the heater. And if you turn the lights on manually outside of the normal ON hours, the heater will go off as well.

why not set it base on the temperature? that way if your MH dosent fire, you still have a steady heat

It is based on temperature. However, I want a back up.


Thanks for the help!!
