Input on KC868-H8B

[Adarrada]

Hi
I have a KC868-H8B v2.2 set up for my deck lights and pool pump which I Ctrl with the app KBOX. 
No, I’m trying to turn on the pool pump each time the air conditioner goes on. 
How can I do that?  
I was hoping I could just run the signal 12v from the thermostat into the input. 
Is that possible?

Does that mean the thermostat is a digital input?

how to control your air conditioner? by IR or other way?
H8B's INPUT can't use by 12v dc, it just use for OPEN or CLOSE dry contact signal.
