Wiring And Setup - Honeywell HPSR103 Installation Instructions Manual

WIRING AND SETUP

Power Input
Honeywell 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
Honeywell 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
Honeywell 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 Honeywell Hydronic Panels are compatible
with Honeywell Equipment Interface Modules in
installations were sufficient wiring is not available.
R: 24V Hot (Commonly Red)
W: Heat (Commonly White)
R W C
C: Common 24V (Commonly Blue)
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
Honeywell 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.
