Carlin EZ1HP oil burner. Not every cycle, during the 120 second post purge, the motor relay drops out for ~1/4 second and kicks back in, about every 3 seconds. The motor just starts to slow down and then one can hear the relay clicking back in. So I bought a new one. Same exact behavior. I...

I'm having the same problem. The L7248C aquastat doesn't seem to know that the ODR module is connected. Anti-short cycle timer and degrees F/C are the only other adjustable parameters besides high limit that come up.

Brand spanking new ThermoDynamics TDX90+ condensing boiler (it hasn't condensed anything yet) with Carlin EZPro burner and direct vent. Positive draft through the entire system (except for the 4" combustion air inlet ductwork that is), so it should leak anyplace there's any gap or hole. The...

Well, the logic may be correct that firing up the oil boiler every time someone tuns on a faucet (or keeping the boiler at temp just for hot water) is wasteful compared to other methods, but there's something seriously wrong with the numbers at...
