8.C Pump Connections and Operation
The controller in this unit energizes the appropriate
pump contacts when it receives a call for heat. Once
the call for heat is satisfied, the pumps will remain on
for the defined pump overrun time.
The Boiler, System, and DHW pump terminals are
found on the Main control board TB1-15A through
20A. They are fed 120 Volts internally from the main
power feed. The current rating of the contacts is
7.4 amps, and an appropriately sized contactor
must be supplied and installed by a qualified
technician to ensure proper pump operation.
Once the system has been installed, the “Pump
Configuration” menu will allow the installer to
adjust Pump control, Overrun time and Demand
control for the various pumps in the system.
NOTE: When running the Power and Field
Connection wirings between the units (Lead
Lag, System Sensor, Outdoor Sensor, Building
Automation, Etc), ALWAYS Exit and Enter the
units through the lower back panels so that
during future servicing, the wires are not in the
way and do not have to be disconnected in
order to remove the top and side panels.
AVIS: Lors de l’exécution du domaine
d’alimentation et les fils électriques de connexion
entre les unités (Lead Lag, Capteur, système
capteur extérieur, domotique, etc), TOUJOURS
quitter et entrer les unités à travers la partie
inférieure arrière de sorte qu’au cours de
l’entretien futur, les fils ne sont pas dans la voie et
n’ont pas à être déconnecté afin d’enlever le haut
et le côté.

CAUTION
The supply voltage to the unit must not be
disengaged, except for service or isolation, or unless
otherwise instructed by procedures outlined in this
manual. To signal a call for heat, use the correct
terminals as instructed in Section 8.
