Yes...that is another thing.
Usually if it is that far off then maybe
it is setup as platinum and not nickel.
I would still check the calibration table and change the AIs back to factory...
Are you trying to maintain discharge air/ mixed air?
Do you have a preheat valve?
Might just be able to adjust the PID loop...
Follow the procedure pare provided, verify the readings are the same
as the factory readings on the sticker on the back on the DX
then calibrate accordingly...
The mixed air temp should not have anything to do with a relief damper...
Maybe you're talking about the OA damper?
If you truely talking about relief damper then it has to be

Just an update...
Found no documentation but the relief valves are rated for 15 psi.
We installed local pressure controls for each boiler to modulate
low and hi fire at 12 psi.
I put the...
First, I would check to see if the graphic

Thanks for the replies...I will update you later!!!
It is two stage low/hi fire control.
Thanks for the replies...
I believe ctrlguy is correct when he says
the valves were undersized when installed, the current steam pressure is lower than design
The problem is on VERY cold days,...
We have 3 steam boilers that supply steam heat to certain places in the bldg.
Each boiler has pressure controls to switch from low to high fire.
The current steam header pressure setpoint on the...
What is the most efficient way to control steam boilers?
