compressor kicking on with heat?

[INTMD8]

Hi guys, after a bit of maintenance on my 68, bleeding the coolant system I noticed that when I push in the button for heat the A/C compressor kicks on.

I'm assuming this is not correct?  If so any ideas on what I should take a look at? Thanks!

it will, there is a humidity controller on the bottom of the ac case that turns the compressor on.

From the 69 FSM, I'm sure 68 is similar:

"Time belay Relay (Coronet and Charger)
A vacuum actuated time delay relay is located on
the bottom of the fresh/recirculating air door housing.
The purpose of this relay is to reduce the interior windshield condensation to an acceptable level.
When the ambient temperature is above 25 degrees, and the heat or defrost buttons are pressed, the air conditioner will go on for a period of 1 to 10
minutes.
If the system is shut down for less than ten minutes no delay will occur upon restarting. The relay will reset automatically after ten minutes shut down."

Ran it again today and it works just as you guys described. So I guess it's not broken 

Thanks again
