Jackson Systems The Green Zone Z-300-HPS User manual

Sequence of Operation:
The Green Zone™ Z-300-HPS is a residential /
light commercial zone control system that allows
a single HVAC unit to have up to three separate
zones. Each zone is controlled by its own space
thermostat and motorized zone damper. If a zone
thermostat calls for heating or cooling, the zones
not calling will have their dampers powered
closed, and the zone calling will have its damper
opened. The heating or cooling equipment will
also be brought on at the same time. When the
zone calling is satisfied, the heating or cooling
equipment turns off. If one zone calls for heating
and another zone calls for cooling, the first zone to
call receives priority. When the first call is
satisfied, the system will changeover and take
care of the opposite call. If a zone being served
(heating or cooling) has not been satisfied within
20 minutes while an opposite call is taking place,
the system will changeover. When the zone is
satisfied or 20 minutes has elapsed, the system
will again changeover if an opposite call exists.
This is referred to as Auto Changeover - First Call
Priority - Time Share. In the event of a tie, cooling
will receive priority. The changeover valve only
changes position when the mode of operation
changes.
High and Low Limit Protection:
The Z-300-DAS Discharge Air Sensor should be
mounted on the discharge air plenum of the
HVAC unit and wired to the DAS terminals on the
panel. If the heating temperature rises above
140° F (160° F when fossil fuel is selected) or if
the cooling temperature falls below 45° F, the
sensor will cycle the equipment, while the fan
continues to run. When the system goes out on
low limit a 3 minute time delay is activated before
cooling is allowed to energize (providing the
discharge air temperature has risen above 45°
F). LIMIT LED blinks when high or low limit is
reached.
Ventilation Mode:
Zone ventilation is established by the individual
zone thermostat fan setting. Any thermostat set
in the fan AUTO mode will not receive ventilation
air when there are no heating or cooling calls.
Any thermostat set in the fan ON mode will
receive ventilation air whenever there are no
heating or cooling calls taking place.
Power Requirements:
The Z-300 requires a separate 24 Vac
transformer. A 40 VA transformer will power the
panel and up to four (4) dampers. A 75 VA
transformer will power the panel and up to seven
(7) dampers. If more than three (3) dampers for
an individual zone are required, a RY-1-HB relay
should be used with an additional properly sized
transformer. Jackson Systems HD-XXXX
rectangular and D-XX round dampers are
powered closed / spring return open. Damper
actuators are rated at 10 VA. If 3-wire dampers
(powered open / powered closed) are installed,
VA ratings will vary depending on the damper
actuator used.
Wiring:
All wiring should be conventional 18 gauge
thermostat wire. Thermostats and zone dampers
may be located up to 300 feet from the Z-300
panel.

Installation
Mounting the Panel:
Carefully remove the Z-300 panel and cover
from the shipping carton. Slide the PC board out
of the snap track base and mount the base to a
flat surface either on or near the HVAC indoor
unit in an area that will facilitate easy access for
wiring. Reinstall the PC board by carefully
centering it over the base and snapping it back
into the track groves.
Wiring the Zone Thermostats and Dampers:
Refer to the logic panel wiring diagram. Wire
zone 1 thermostat and its associated damper to
the ZONE 1 terminals on the logic panel. Wire
zone 2 and 3 thermostats and dampers in the
same manner.
Wiring the HVAC Equipment:
Wire the HVAC unit to the Z-300-HPS HVAC
UNIT terminals. Note: Do not wire the equipment
common to the Z-300-HPS panel.
Installing and Wiring the Z-300-DAS
Discharge Air Sensor:
Drill a ½”hole in the middle of the main discharge
air plenum approximately 18” downstream from
the heat pump electric stip heaters or furnace
heat exchanger. Remove the Z-300-DAS cover.
Slide the probe into the hole and use two self-
tapping sheet metal screws to secure the base
making sure that the gasket is in place. Use 18-2
thermostat wire and wire nuts to attach the
sensor leads. Replace the cover and wire the
sensor to the DAS terminals on the Z-300 panel.

Wiring the Transformer:
Wire a separate 24 Volt transformer of the proper
VA to the logic panel terminals marked (R) and
(X). Do not power the panel up until wiring is
completed.
Test, Check and Startup:
1. Verify that all component wires have been
connected to the proper terminals and are
secure.
2. Disconnect the HVAC equipment (R) terminal
wire at the panel and apply 24 volts to panel.
3. Take a jumper wire and momentarily short the
DAS terminals. This will put the panel’s time
delays in “speed up” mode.
4. Place the zone thermostats in the OFF
position.
5. Place zone 1 thermostat in the heating mode
and have the thermostat call for heat. Confirm
that (ZD1) LED is ON and that (W) LED is ON.
Confirm that zone 1 damper is open and zone 2
and 3 dampers are closed. There will be no
voltage across zone 1 (D) and (D) terminals and
24 volts on zone 2 and 3 (D) and (D) terminals.
6. Put zone 1 thermostat in the cooling mode and
have the thermostat call for cooling. Confirm that
(ZD1) LED is ON and that the (Y) and (G) LEDs
are ON. If the thermostat has internal time
delays, the cooling call may not activate
immediately.
7. Turn zone 1 thermostat off and repeat steps 5
and 6 with zone 2 and 3 thermostat. Remember,
the zone calling will have its damper open and
there will be no voltage on the (D) and (D)
terminals for that zone.
8. Determine the ventilation mode of each zone
thermostat by setting the thermostats in the Fan
AUTO or ON mode.
9. Remove 24 Volts to the panel and reconnect
the HVAC (R) wire.
10. When 24 Volts is again applied to the panel,
the internal time delays will be activated.
11. Confirm that the LIMIT LED is ON. If not,
check LIMIT wiring. If the system goes out on
high or low limit, the LIMIT LED will blink.

Fossil Fuel Applications:
Fossil fuel may be used as the auxiliary heat
source with the Z-300-HPS allowing for up to 2
stages of cooling and 3 stages of heating. For
systems having a 2 stage furnace, W1 and W2
are jumpered at the furnace. This method utilizes
the internal furnace upstage timer to bring on
second stage fossil fuel.
Sequence of Operation:
2 Heat / 1 Cool
When a zone thermostat calls for heating and the
outdoor temperature is above the balance point
as established by the Z-300-OTS, the heat pump
operates as first stage heat. If there is a call for
second stage heat (auxiliary), or if any
thermostat is placed in the emergency heat
mode, the panel will automatically de-energize
the heat pump and bring on the furnace. When
the outdoor temperature falls below the balance
point, the heat pump will be locked out and the
furnace will become first stage.
3 Heat / 2 Cool
When a zone thermostat calls for heating and the
outdoor temperature is above the balance point
as established by the Z-300-OTS, both
compressor stages of the heat pump will operate
as normal. If there is a call for third stage heat
(auxiliary), or if any thermostat is placed in the
emergency heat mode, the panel will
automatically de-energize all heat pump stages
and bring on the furnace. When the outdoor
temperature falls below the balance point, the
heat pump will be locked out and the furnace will
become first stage.
Installing and wiring the Z-300-OTS
The Z-300-OTS is an adjustable electronic
sensor used for both selecting the outdoor
balance point and measuring the outdoor
temperature. This information determines when
the heat pump will be locked out and only the
furnace will be used for heating.
Before installing the Z-300-OTS, remove the
retaining cover and select the outdoor balance
point temperature using the slide switches.
Mount the Z-300-OTS on a vertical surface
inside the heat pump cabinet to avoid direct
sunlight, freezing rain or snow.
