This next sample screen shows that the outdoor air temperature has dropped enough to enable the boilers to operate. The system has been running long enough to satisfy all 4 Boilers 5 Minute Starting delay so they are all active at this point. It took roughly 20 minutes to get all 5 relays active since each has a 5 minute Staging Delay time period. Keep in mind that although Relay #1 (OAT Enable) is active, nothing is connected to the output because its only function is to provide an outdoor air enable signal for the boiler staging.
