Sir tasehr . . . . . .
If I hold the momentary switch in when applying power I get an E1 error since the switch is not released.
For further clarification, you get that E1 error and therefore, the AC wouldn't power up and come on ?
But just as soon as you release it and press again the unit will come on , . . .right ?
I can see that you are more than an armchair observer and pipe dreamer since, at the least, you have GOTTEN access to the board and photographed both sides for us.
Now we know nothing of your soldering expertise, any components on hand, and their familiarity, and your capability to make a small perfboard circuit with possibly 10-12 parts on it.
As I observe the board I see that no HEAVY power components are being present, with them being remoted away elsewhere.
I see the two digit display at top, an IR receiver just below it and finally, down at the unit's controller IC, I see access to a filtered 5 VDC supply.
So that would be adequate to wire in and drive a 5V reed relay to simulate a momentary pressing of the frontal SW1..
If you are not up to the prior mentioned situations I would make a slight variant to another suggestion, with the use of a purchased remote controlled doorbell circuit to drive the reed relay.
(If that building is not 300 feet away )

Add:
Is that an indicator LED on the top of the Leviton DZPA1 or a manual activation switch ?
