Can I trigger off an alarm AND another channel being on?

[Linina]

This is what I want -

I want my fans to kick on

1. anytime the lights are on (regardless of temperature - I want them blowing on the endcaps whenever the bulbs are on)
OR
2. if the temperature is above X (just for cooling, even if the lights aren't on).

I figured out how to set it to start off the alarm value (temperature) but I am not sure if I can also force it on when the lights are on. (what I did in the meantime was lower my temperature threshold artificially low so I know it'll trip soon after the lights come on).

set it up as light with a timer the same as your lights and then have an the alarm turn it on also.

I tried that but the fan was cycling constantly near the alarm value (like hits 80, fan trips on, hits 79.9, fan trips off).
So to avoid that nonsense of CONSTANT fan on/off I thought I had to use the controller option (for temp control with a range of tolerance so it's not on/off constantly) but then I dont see how I can also have it on anytime another channel is on.

I didn't think about that....

Set an alarm to the output plug for you lights.
Value = 0
Trip = above

Then in the temp controller programming set the alarm to point to the alarm you set above and to be on if tripped.

Ok I'll give that a try - thanks much!

Another option you can do is make the fan a controller for the channel of the lights.

For example: if you had your lights on CH1. Make the fan a controller function.

Device: CH1
target: 0.50 (I prefer right in the middle)
hysteresis: 0.02 (choose a small number here)
ON when: high

also make the alarm activate with the temperature you want. You can choose to turn the channel (fan) on based on the alarm. This way it will turn on if the temperature gets too hot and wont turn off on you if the light is still on. Hope that helps.
