Sometimes The outdoor temperature reading keeps keeps bouncing up and down
within one degree of the setpoint call for heat.
The outdoor air temperature will equal the setpoint temperature for a a few seconds.
The boiler will begin its purge cycle.
Suddenly the outdoor air temperature will go one degree or two above the setpoint.
The boiler will then shut down.
The outdoor air Temp will then drop about a degree below setpoint.
Once again the boiler starts its purge cyccle
This happens at about a 37 degrees O.A.Temp .
The setpoint is 36 degrees.
Is there any way to dampen the Heat Timer Response
The outoor air sensor appears to be accurate.
