Lochinvar

2024-11-05, Tuesday:

Weather was overcast, very lightly snowing, the driveway loop was dry, the circle loop was dry, Outside temp above 40-degrees:
- Main control box was still active, clicking PUMP OPEN relay and LED on/off over 5-10 second period
- Slave control box was quiescent, no LEDs lit
- Lochinvar ventilation fan was on (noisy), which is always on it seems no matter what
- Primary loop and secondary loop pumps were running
  - Q: is this normal behavior, for the ventilation fan in the boiler to be always on, if even if the boiler is not burning?
  - Q: is the 'cycling' of the PUMP OPEN relay in the master controller normal?
