Burnham series 2 beeping noise and status 8 errors?

yesimon

The boiler intermittently beeps and displays status 8 while running. According to documentation status 8 corresponds to "Boiler Running but Circulator is not Running". However, the 007e displays an orange LED = on and there's circulation.

Is it possible that this alert is a false alarm? My hypothesis is that the 007e is very efficient and drawing so little power that the controller thinks it must not be running correctly . Since the only communication the board has with the circulator is sensing the power draw.

Is it possible to adjust the sensitivity or disable this alert?

Hi
007e could be running but not moving water. 

Is pipe hot on both sides of the pump?
We’re proud to say our pumps don’t suck. Lol
It displaces water with full pump volute so pump has to be primed or flooded suction.
let me know how it plays out.
also, you can call Taco Tech support at 401-942-8000 for more help.

I would check with Burnham on this. I could be wrong, but I don't think the controller on the boiler would be reading the amp draw of the circ. It probably knows it sends power to the relay and closed that relay.

Status 8 says the heating circ is off and there is a DHW call. I would double check the wiring from the thermostat and the aquastat as well as the different circs are landed on the correct terminals

They must've changed the Series 2. I thought it was just a simple aquastat on them.
If it's a new Series 2 or a different model and has a digital control, its probably not the draw on the circulator being measured, but the supply and return temperature. 
Can you post a pic of the wiring diagram?
The actual model number too.

@yesimon this is what I received from US Boiler ( Burnham ). I would reach out to them:

The IHC control on the series 2 boiler will sometimes develop a beeping noise that has nothing to do with its operation (it can be replaced if it is annoying, but it doesn’t effect the boilers operation). Also the Status 8 is not a fault code indicates that the burner is lit and running, the control doesn’t know if the system pump is running or not. If the pump wasn’t running the boiler would just cycle the burner off and on as the boiler hit setpoint and cooled off. Feel free to reach out to our tech line at 717-397-4701 and select option 2 and option 2, or a return email.

This appears to be what's happening. Looking at the manual gives two definitions for status 8:

1. Burner runs until call for heat is satisfied or operating setpoint is reached.
   
2. Domestic Hot Water (DHW) Priority Forcing Circulator Off
   

After examining the control, the DHW terminals are not even connected, so it probably just indicates standard operation. Sorry to say the beeping alarmed me incorrectly.
