I put some values in the odr settings in the whn 55 with fin tube baseboard.
0 degree 160
70 degree 97.
The thermostat is one of the Honeywell programmable and after reading about it online and watching it spaz out and cycle the boiler for about 1 minute I set it to a 72 degree hold.
It was 42 degrees last night and the temp climbed to 70 before I went to bed.
I originally put a jumper so both zones would activate because the bed zone is too small. This made bedroom get to 71 even though that tstat is currently off. So I removed the jumper and set the bed tstat to 68 so that small zone will stop and the large zone would always run before going to bed. I also dropped the 0 degree to 157 to try and get it to 68. I'll find out when I get home from work
This morning the boiler was still running at 25 percent output the bedroms were at 68 and the house was at 70 degrees. The thermostat was still set to 72 hold. According to the sh counter it never shutoff
The house zone it set to 15 degree delta t with a viridian pump and the bedroom is set to 12 to try and keep both rooms the same temp.(I'll probably have to add some baseboard to the other bedroom but that's another project).
The boiler is only seeing about 4 delta t at pump speed 1 running this low temp. I may swap it for a vr1816 which is more variable with its speed
So when it gets cold again I'll probably have to play with it some more.
I know at a certain point the fin tube doesn't work with the cooler water like a ci rad would. Do you think the odr high temp is too low?
