Honeywell Hydronic Panels include a convenient wiring
terminal for wiring 120V/60Hz/1Ph power. These
terminals, found at the bottom right side of the panel,
provide power to the transformers and all valves installed
on the system.
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 right 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
Zone Panels are compatible with electronic,
power stealing and electromechanical thermostats.
Dedicated R and W terminals provide heat call messages
from the thermostat to the zone panel. A C
also available for each thermostat to provide axillary 24V
NOTE: It is up to the installer to ensure that the 40VA per
transformer limit is not exceeded.
Honeywell Hydronic Panels are also 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.
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.
A grounding wire has been provided in the pump wiring
Circulator Pump Operation
The HPZC10* Zone Panels are compatible with common
circulator pumps and should be wired as shown in the
following diagrams. Each Zone Control Panel can operate
2 circulator pumps at the same time. The Pump End
Switch will close a set of dry contacts with every call for
heat while the Normally Open 'Zone 1 Pump End Switch'
will close a set of dry contacts only when priority zoning is
enabled and there is a call for heat from the priority zone.
With no call from the priority zone the panel additionally
offers a second set of Normally Closed contacts that will

24V zone valves and can be wired as shown below or in the
wiring diagrams on page 3.
