Relay Output #5 Programming ( Used for Boiler #4 )
The fourth boiler stage is enabled to operate if the water temperature is below 150°F and
will remain on until it rises to 170°F. The fourth stage can only operate if the third boiler
stage relay #4 has been active for at least 5 minutes. Once activated, this stage must
remain on for 5 minutes and once de-activated it must remain off for 10 minutes.
The Starting Delay Period that was set for stages 2 to 4 prevent all four boiler stages
from activating at the same time as soon as they are enabled to begin operation. Each
stage must run for 5 minutes before the next stage can be activated.
Analog Output Programming
Control Source Not Configured
Since no analog output control is required, simply leave the Control Source set to Not
Configured on both outputs and no analog output control will take place.
