Jackson Systems Comfort System Z-300-HP Quick start guide

The low limit (FS-38) should be wired to
the “LL” terminals on the control panel
(remove jumper). The compressor will
shut off when low limit trips out.
The high limit (HL-170-HP) should be
wired to the “HL” terminals on the panel
(remove jumper). The compressor, auxil-
iary heat and emergency heat will shut
off when the high limit trips out.
A 40 VA transformer will power the con-
trol panel and up to four (4) dampers.
A 75 VA transformer will power the con-
trol panel and up to seven (7) dampers.
Up to three (3) dampers can be connected
in parallel. A total of no more than seven
(7) dampers may be connected to the sys-
tem. A system may be a single panel or
multiple panels.
If more than three zones are required, two
additional control panels can be used to
control up to a total of nine (9) zones. T5
terminal strip is used only when more
than three zones are required.
Label the dampers, damper wires and
thermostat wires with the zone number
and the area they serve.
Manual Changeover
Installation Notes:
To install the panel, first slide the PC
board out of its base and screw the base
to a flat surface next to the HVAC
equipment. The PC board should be
reinstalled by centering it over the base
and pushing firmly.
Connect only 24Vac to Control Panel.
The zone control panel requires a sepa-
rate 24 Volt transformer.
No special wire is required.
The thermostats and motorized dampers
may be located up to 300 feet from the
control panel when using 18 gauge ther-
mostat wire.
Fuse F1 (4 Amp) protects the relay con-
tacts. Fuse F2 (4 Amp) protects the
printed circuit board.
Zone dampers are powered closed /
spring return open.
If the heat pump is not equipped with
short cycle protection, a short cycle pro-
tection timer (TD-5) should be installed.

When green zone LED’s
are on, those zones are
calling for heating or
cooling.
If the thermostat does not
have an “EH” terminal,
disregard “EH” on the
zone panel.
All thermostats must
be set in the same
mode.

Sequence Of Operation
Comfort System™ is a residential / light commer-
cial zone control system that allows a single
HVAC unit to have up to three separate zones
(nine if three panels are connected together). Each
zone is controlled by its own space thermostat and
motorized zone damper. If any of the zone
thermostats call for heating or cooling, the zones
not calling will have their dampers powered
closed, and the zone(s) calling will have its (their)
damper(s) remain open. The heating or cooling
equipment will also be brought on at the same
time. When all zone thermostats are satisfied, the
heating or cooling equipment turns off and all zone
dampers return to the open position to allow for
continuous air circulation. This is a manual
changeover zone control panel.
Thermostats
The Z-300-HP works with standard, heat pump
thermostats. All thermostats must be set in the
same mode. Thermostats must not be set in the
auto changeover mode.
Typical System
Verify that all wires have been connected to the
proper terminals and are secure.
Verify that the jumper across the “LL” and “HL”
terminals were removed before connecting the
high and low limit stats.
The low limit (FS-38) should be connected to the
“LL” terminals on the zone control panel. The
high limit (HL-170-HP) should be connected to the
“HL” terminals on the zone control panel.
Zone dampers are powered closed and spring
return open. There will be no power at the panel
damper terminals marked “D” when the damper is
in the open position.
When a green zone LED is on, that zone is calling
for heating or cooling.
To check the system for proper operation, pull the
disconnect for the condensing unit to prevent short
cycling. Next, place all the zone thermostat mode
switches in heat mode and turn down all
thermostat set points. Go to each zone thermostat,
one at a time, and call for heat to verify that the
proper zone dampers are open (and the rest are
closed). Turn the zone thermostat back down
before checking the next zone.
