5. Product introduction

5.1 Features and benefits

• Compatible with 2-, 3-, and 4-wire low
voltage controllers or thermostats.
• Wiring ease with 120 VAC, ground and low
voltage screw terminal inputs.
• Low voltage end-switch output terminals for
the zone valves.
• Zone priority with selectable time-out feature
• Pump exercise feature, selectable 72-hours
or 14-days.
– The pumps will be turned on for 30
seconds every 72 hours or 14 days in
order to prevent pumps from seizing up.
This feature will only work if there is a
jumper wire connecting the ZR ZC
terminals on the pump controller.
• Post purge feature for pump controllers (3, 4,
and 6 zones).
– After the priority zone calls for heat, the
priority pump will be allowed to run for an
additional 2 minutes after the thermostat
contacts open. This allows some of the
residual heat in the boiler to be transferred
to the water.
• Boiler demand terminals.
– The two terminals, labeled MAIN XX, are
wired to the boiler. When the contacts
close, the boiler starts and will come up to
a preset temperature for hydronic heating.
• DHW terminal.
– The two terminals, labeled PRIORITY XX,
are wired to the boiler. When the contacts
close, the boiler starts and will come up to
a preset temperature for domestic hot
water heating.
• ZR and ZC terminals.
– Available on the pump controllers only.
These terminals are connected by a
jumper wire at the factory. The ZR terminal
is always powered with 120 VAC. When
you remove the jumper wire, all 120 V
power is removed from the pumps.
• Front facing LED indicator lights on the
cover.
• Side-mounted terminal connections for ease
of wiring and installation.
