Long story short version.
I have a new gas fired steam boiler.
But the old thermostat is still in use.
I want to install a new digital one, Honeywell TH4110D.
The new thermostat is in a different location.
So i cannot just copy whats there.
My one important question is this ; does it matter which of the heat relay wires the w wire from the thermostat is connected to?
here a link to my hand draw schematic.

Brian,
The drawing is done correct.
It don't matter what side of the relay is on W of the t-stat.
Make sure you set up the t-stat to steam heat (1-CPH)
