WIRING AND SETUP
Power Input
Hydronic Panels include a convenient wiring terminal for
wiring 120V/60Hz/1Ph power. These terminals, found at
the bottom left side of the panel, provide power to the
transformer and all pumps installed on the system.
Status Indicators
Hydronic Panels feature Advanced Status Lighting. This
includes a transformer status light on the status panel,
and an Input Power Status Light near the bottom left
corner of the Zone Panel. These indicators show the Power
Status of the Panel at all times.
NOTE:
Line volt LED is not visible with mylar cover
installed.
Zone Pump
Hydronic Panels are compatible with common zone
Pumps and can be wired in as show in the wiring diagrams
on pages 4 and 5.
Thermostat Compatibility
THE HPSR10* zone panels are compatible with electronic,
power stealing, and electro mechanical thermostats.
Dedicated R and W terminals provide heat call messages
from the thermostat to the zone panel and with C terminal
may also provide auxiliary 24V power to electronic
thermostats.
NOTE:
It is up to the installer to ensure that the 40VA per
transformer limit is not exceeded.
Additionally Hydronic Panels are compatible with
Equipment Interface Modules in installations where
sufficient wiring is not available.
Fig. 8.
NOTE:
For power stealing thermostats, wire to R and W
on the zone panel. There are no additional com-
ponents required to make these thermostats
function. For all thermostats that require a C wire
for power there is a C terminal available on the
panel for each thermostat.
Priority Override
Hydronic Panels support priority operation and can be
enabled with the use of a switch located in the top right
section of the panel labeled "Priority Zone".
When priority operation is enabled, the panel employs a
priority override function which operates as shown below:
1.
If a priority zone calls for 60 continuous minutes,
priority operation is disabled and control is returned
to each zone.
2.
Once the priority zone satisfies, priority override is
disabled and standard operation resumes.
Grounding
A grounding bar has been provided below pump
connection terminal blocks.
R: 24V Hot (Commonly Red)
W: Heat (Commonly White)
C: Common 24V (Commonly Blue)
