What am I doing wrong

maybemark

circs like low much better
system is 107 {128}
flame 100%

maybemark

durring the day, I set the stat back I think 5 or 6 degrees
what your asking the house will be unable to live in comfotably
if your telling me to set the stat at 85.
you say play with the odr parameters Is that under outdoor reset?

Gordy

So long as the rads are getting the flow they need. That's fine. You said before the house was comfortable.

maybemark

can i turn down the valves of the radiator

maybemark

yes, the house has been comfortable, but the lowest we have had was 30, now
system is at 110 {128}
100%flame

maybemark

the house is comfortable, just a little out of balance. The living room has always been a problem
I don't unstand why 185 to keep it at
it will be insane hot in here

maybemark

system 112 {128}
flame 100%
outside temp 32
inside at stat 70

Gordy

what you are,shooting for is the reset curve doing all the work. You will never get it set optimally if the thermostat interrupts that setting process. You shift your reset curve so the water temp is just enough to off set the heat loss to what you feel is comfortable.

Gordy

Once that is done your golden, and the boiler will run optimally.

maybemark

I need it to stay on at 185 for a couple days? and no setbacks
I will be so uncomfortable for a few days
I'm happy at 71, your asking 85

maybemark

what does it mean by shifting the reset curve. Is this something the boiler does on it's own, or I have to do something manually?
what do i do?

Gordy

If the temp climbs above 71 then then you need to shift the curve to a cooler supply temp. You may need to set the shift to -9 instead of 9 where you have it now.

maybemark

is the curve the {128} on the boiler?

maybemark

114 {128}
flame 100%
outside 32
inside

maybemark

I have to go walk my dog, will be back in 15 minutes

Gordy

Yes that is the target temp the boiler is trying to reach.

Gordy

The shift curve function allows you to tweak that number +18 to -17 degrees. So your at + 9 now you said right?

Paul48

he's walking the dog Gordy.

Gordy

Sigh

SWEI

If you absolutely must have a setback, we'll address the right way to do that -- after you have the ODR curve dialed in.

maybemark

I'm back
118 {128}
outside 32
inside 70

maybemark

119 {128}
flame 100%
outside 32
stat 70

maybemark

I changed the reset to -1
117 {117}
flame 83%
outside 32
inside is 70

maybemark

118 {117}
flame 79%
outside 32
stat 70

maybemark

should i set the odr lower than -1?

SWEI

Note the indoor and outdoor temps every hour or so for at least a day. The boiler should not shut off much, if at all. If the house overheats the thermostat will shut the boiler down.

Adjust the ODR curve and repeat.

maybemark

can i turn the temp down to something more comfortable than 85?

maybemark

can i keep the heat at 71 all the time, instead of 85?

maybemark

117 {117}
flame 74%
outside 32
stat 70

maybemark

the circs are on low

SWEI

If by "the heat" you mean the thermostat setting, no. We really do start with them set at 85°F or 90°F. That lets us zero in on the adjustments rapidly.

If the room gets over 71°F (and there's not a lot of sun shining in, a woodstove burning, etc.) then head for the boiler and start adjusting. You should be able to get within 2-3°F in a day or so, at which point you start looking for days with higher highs or lower lows so you can fine tune.

maybemark

what is a fine tuned boiler flame % is?

maybemark

117 {117}
flame 72%
outside 32
inside 70

Gordy

Ultimately the boiler never shuts off the modulation just drops to maintain the indoor temp according to what's needed to off set the outdoor temp.

maybemark

the heat in the house is way out of balance
70 in bedroom

Gordy

Your low outdoor air setting is 180* IF you run out of shift adjustment you have some more yet drop that to say 160 170 then play with the shift again. NOT YET though see where what you have gets you.

maybemark

66 in living room (always cold room in house)
68 in kitchen
way out of balance, do not know what it is upstairs

maybemark

the flame is still at 72% and 117 {117}
obviously this is better, should it be better yet, than 72% for flame?

SWEI

The high mass of water and steel in your system is a giant flywheel. Think of the thermostat as a clutch. Think of the supply water temperature setting of the boiler as the throttle. ODR is the cruise control. The goal is to get the cruise control running the car at a constant speed without having to use the clutch.

maybemark

I have to work on the valves of the radiators, see if I can balance the system better than it is
