Can the fan unit and the light unit be on the same switch/timer?

If that's what you want, I don't know why not. What do the instructions suggest? Let me guess, you don't have the instructions.
If you are only feeding one bathroom with a dedicated circuit you may have the light an fan on the same circuit and both can share the same switch.
Some building codes require the light and fan be controlled by the same switch. Be sure to check your local code.
You must be careful however if you decide to add in heat. Any one fastened in place piece of equipment cannot exeed 10 amps. This would limit your combo unit to a total of 1200 watts at 120 volt. By installing on the same circuit and switch you would include the fan and heater in this total.
Please reference NEC 210.11 (3) and 210.23(A)(2)

Thanks for the replies.
There are three dedicated 20A bathoom circuits being put in. One for the gfci receptacles. One for the heater and one for the lights.
The heater is one of those vent/light/heater units. I will only want that light and the fan on one switch/timer. The other six can lights will be controlled by two other light switches.
Load capacity wise, I am fine. I just did not know if there was any code prohibiting the exhaust fan and light being controlled by one switch.

That's perfectly fine.

Thanks guys. By the way, is there anything more of a pain in the azz than trying to stuff cold 12/2 wires and connectors in one of these fan/light/heat combos? Could they have made the wiring compartment any freaking smaller?

Holy ****, that bathroom must be the size of my house to have three dedicated circuits in it.

thats why you use 14-3 for the fan/light.

I wanted the lights and receptacles on separate circuits. I will have 7 can lights and two sets of vanity lights. Too much to add this to the receptacle circuit with the wife using a curling iron and hair dryer. Then I put the heater on it's own circuit since it draws 12 amps.

I did that in the spare bath. Still, shoving a 14-3 and a 14-2 with all the wire nuts was still a challenge.
