Taco relay wiring

[Bangon61]

Can't figure out why my taco relay isn't sending power to my pump. As you can see in pictures, I have 24 vac to r and w inside relay. Also have 24vac to r and com. On the lower connections I have 110v going to n and h. But no 110v to n and 4. Thermostat says calling for heat. What am I missing? Thanks in advance

What is N (neutral?) to the ground?
What is H (L1) to the ground?
Before the call (relay goes active) for the pump to turn on?
Same questions for the above when the call for the pump to come on.

I am not sure if you also measured the relay's voltages correctly before the call signal or after the call signal was made from boiler and or thermostat.

Thermostat or end switch isn't calling.
Meter R to W 24vac not calling
Meter R to W 0 vac calling
Meter R to common. 24vac
Still not working check the fuses
Bad fuse across it 120vac
Good almost 0 vac probably 1 or 2 volts

Sew. When I jump the wires on the stat, everything is groovy. Apparently honeywell support is in order.

Model of the stat?

Honeywell rth8580 I believe. I figured it out. Thank you
