Hydronic diagram is for illustration purposes only, some components have been removed for simplicity.
NOTE: 120 VAC is only sent to the SEC PUMP terminals on the
control that receives the call for heat. For instance, if a zone
from the Master control calls, the SEC PUMP on the Master
control sends 120 VAC and SEC PUMP on the Slave control
does not. When using a single secondary pump with 2 (or
more) controls you must wire the secondary pump to the SEC
PUMP terminals on all of the controls.
