Burnham ES2 with IQ Outdoor Reset Module Issues
My thermostat is set to 70 but my house is 63.
Can somebody please look over my settings. I keep messing around with them and I'm not sure if they are correct? What settings can I change to make the temp reach 70?
Any help would be greatly appreciated. System is new and was working fine until the temp dropped to 15 degrees.
I have a Indirect water heater
HL = 180
dF = 15
Or = 0
PP = 2
St = 140
Pt = On
dh = dh
IQ Outdoor Air Reset
DS = 180
PT = 0
SS = 170
tb = 20
Lo = 0
Ho = 70
Lb = 110
Hb = 190
Lt = 130

I don't see anything terribly out of line Billy...
HL = 180 <-- set this at 190F also
IQ Outdoor Air Reset
DS = 180
PT = 0
SS = 170
tb = 20 <-- try shortening this "Boost Time" to 10 . This setting will boost water temperature after xx minutes if the heat call has not satisfied.
Lo = 0 <-- if you raise this setting the boiler water will run hotter at higher temperatures. It MIGHT help you a bit to raise it. Try 10 .
Ho = 70
Lb = 110 <-- this won't help the current problem I don't think, but this should be a bit higher.. say 130
Hb = 190 <-- this is already pretty much as high as you want it.
Lt = 130
When the system is running, what temperature water are you getting (boiler gauge reading?) (or bt reading)
What SETPOINT (Sp) does the control report is being targeted?

I dont think now is the time to try to mess with the settings...
Im calling it a night so cant help now, but cant you just disconnect the ODR and run the boiler to normal set point until you have time to repair/troubleshoot?
Troop?

NJ Trooper thank you so much for the response.
I made all the changes you recommend.
When the system is running I see
BT = starts running at 165 goes down to 160 then goes up to 180 shuts off then reaches 199 starts going back down
SP = 180

Sounds like the temp is already maxed out. Changing settings might not help much.
What kind of heat emitters do you have? fin-tube baseboard? Is so, when was the last time covers were removed and dust vacuumed out of them? Makes a difference... even a thin coat of dust can cut down quite a bit on heat output.

The SP says 180 and the HL says 190
I didn't see that you said to change HL = 180 <-- set this at 190F also
I changed that as well.
I have fin-tube baseboard and I have never taken the covers off to vacuum.
Just the burner shuts off once the BT hits 180

Ok now it changed
BT goes up to 190 then the burner shuts off
Goes up to 209 then drops back down to 174 then starts back up again.
BT drops to 161 then goes back up to 190 then repeats

Sounds like it's running pretty much flat out... my system is too, I think everyone's is!
Cleaning that dust will help a bit, you will definitely get more heat output from the baseboard. A bit of work, but worth it IMHO...

With the outside temp being -10 with the wind chill here in NY can I change these settings to get a little help? House is 62 with thermostat set at 70
IQ Outdoor Air Reset
LO= setting is 10 can I change it to higher like 15-20?
HL = 190 - Can I change that to 200?
Would these changes help?

As cold as it is, that unit must be running 100% duty cycle then... non-stop, right?
Changing the LO at this point isn't going to do anything, it's already at it's maximum setpoint.
You will get some extra heat if you increase it to 200F ...
Have you removed the covers from the radiators and vacuumed out the dust? If not, DO IT! It WILL make a difference if they are packed up with dust...
If you can't get the heat out of the boiler and into the home, you can adjust the temps all you want and nothing will change.

Trooper I agree with everything except the LB setting. It is defaulted to 110f which was raised from 70f way back. I feel 110f is too high I would rather see 100 or even 90f.
The LB is nothing more than the bottom of the heating curve. In other words if it is set at 110f and HO (High Outdoor Air) temp. So at 70f OD the boiler water temp will be 110f. In reality it will be 130f. The LT is 130f. So any setpoint below 130f the control will still go to 130f. the industry says the LB should be set at the thermostat setting
The LO should be set to the areas OD design temperature. If he changes it to 15f than he would be at 180f at 15f instead of 0f OD temp.
If you raise the HO 10f from 70 to 80fit will normally raise the indoor water temp by about 4-5f.
Take a look at the pix, self explanis.
