READ THIS MANUAL THOROUGHLY BEFORE PROCEEDING WITH INSTALLATION
INTRODUCTION
The Z-600 Comfort System™ is a residential and light commercial forced air zone control system that allows a
single HVAC unit to have up to six separate zones. The system can be expanded to as many as 12 zones by
adding 3-zone expansion modules. Intuitive firmware allows the panel to be used with single stage, multi-stage,
heat pump and dual fuel equipment having up to 3 stages of heating and 2 stages of cooling. Standard heat / cool
or heat pump thermostats can be used with the Z-600, along with a choice of two or three-wire zone dampers.
Simple slide switch configuration allows for a wide range of system setup and control options best suited for each
zoning application. Additional features include, fuse protected inputs and outputs, easy-to-read and access wiring
stat
terminals, LED
point controls, and selectable ventilation and purge modes. An adjustable upstage timer allows single stage
thermostats to be used with multi-stage equipment. Capacity Control can also stage equipment based on the
number of zones calling. The Z-600 comes in an attractive and rugged 2-piece anodized aluminum enclosure that
provides easy access for wiring, system setup and diagnostics.

SYSTEM STATUS LED DEFINITIONS AND FUNCTIONS
SEQUENCE OF OPERATION
Each zone damper 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
zones calling will have their dampers open. The heating or cooling equipment will be brought on at the same
time. When all zones are satisfied, the heating or cooling equipment turns off. Zone dampers then reposition
based on ventilation mode selection. The system can be set up to operate in either Cooling Priority or Majority
Wins mode.
COOLING PRIORITY MODE - If any zones are calling for heating and a zone calls for cooling, the cooling will
receive priority and the system will operate in the cooling mode. When all cooling calls are satisfied, the system
will automatically changeover and take care of the heating calls.
MAJORITY WINSMODE - If more zones call for heating than cooling, the system will be in the heating mode. If
more zones call for cooling than heating, the system will be in the cooling mode. If the number of heating and
cooling calls are equal, cooling wins.

Time Share can be used with either the Cooling Priority Mode or Majority Wins Mode. If zones being served
(heating or cooling) have not been satisfied within 20 minutes and an opposite call takes place, the system will
changeover. When that mode is satisfied or 20 minutes has gone by, the system will again changeover if an
opposite call exists.

en the Fan Mode slide switch is set in the ALL position and at least one zone thermostat is set in the fan ON
mode, all zone dampers will open for ventilation air between equipment calls. When the Fan Mode slide switch is
set in the ZONE position, only those zone thermostats set in the fan ON mode will have their dampers open for
ventilation air between equipment calls.
CAPACITY CONTROL SETTINGS
The three Capacity Control slide switches have a numerical value of 2, 3 and 4. Any switch or combination of
switches set in the ON position establishes the Capacity Control value. This value equals the minimum number of
zones that must be calling in the same mode before a second stage can be energized. Capacity Control only
allows for the upstaging to occur; it still requires a second stage call from the
thermostat
or Stage Timer to actually
initiate the second stage of the equipment. It is recommended that the Capacity Control value equal no more than
50% of the total number of zones. This feature works with multi-stage and single-stage thermostats. The Stage
Timer must be ON when single-stage thermostats are used with multi-stage equipment.

CAPACITY CONTROL VALUES
STAGE TIMER
The Stage Timer switch is located below the Capacity Control switches. When the switch is set in the ON
position, the adjustable Stage Timer is activated. This feature allows for the use of single-stage zone
thermostats with multi-stage and heat pump equipment. The Stage Timer can be set from 5 to 20
minute upstaging. (Typically set at 10 minutes)
ADJUSTABLE LIMITS
High Limit
(Z-600-DAS Sensor) - Set at 170° for conventional heating systems and dual fuel applications. Set at
120° for heat pump. Allows fan to run but shuts off or down-stages equipment to prevent overheating.
Low Limit
(Z-600-DAS Sensor) - Adjustable from 40° to 58° for both heat pump systems and conventional air conditioning. Allows fan to run but shuts off or down-stages equipment to prevent the coil from freezing.
Low BP
(Z-600-OTS Sensor) - Set balance point to prevent heat pump operation when outdoor temperature
falls below setpoint. (Typically set at 35° F)

High and Low Limits -
Whenever the system down stages the HVAC equipment or shuts orst stage due to high or low limit control,
2 minutes must pass before rst stage or upstaging can be initiated providing the discharge air temperature has
dropped below the heating limit setpoint or risen above the cooling limit setpoint.
Dual Fuel Low Balance Point -
Whenever the outdoor temperature drops below the low balance point setting and the system changes over from
heat pump to the auxiliary heat source (gas or oil), auxiliary heat will remain on until the call is satised regardless
if the outdoor temperature rises above the low balance point during the heating call.
USING THE Z-600 WITH HEAT PUMPS AND DUAL FUEL EQUIPMENT
REVERSING VALVE:
Make sure that the heat pump thermostats and Z-600 reversing valve system switch are congured in the same
mode.
O = Reversing valve energized on a call for cooling
B=Reversing valve energized onacall for heating
When the reversing valve is energized on a call for heating (B) or cooling (O), the O/B LED will be ON, The
reversing valve will remain energized until an opposite call takes place.
HEAT PUMP AUXILIARY HEAT WIRING:
The zone thermostat auxiliary heat terminals are marked. The HVAC System auxiliary heat terminal is
marked. (See Typical Thermostat Wiring Diagrams)
THERMOSTAT CONTROL OF AUXILIARY HEAT:
When a zone thermostat calls for auxiliary heat in standard heat pump mode, the auxiliary heat cycles and the
heat pump compressor will be on at the same time.
When a zone thermostat calls for auxiliary heat in dual fuel (fossil fuel) mode, the heat pump compressor is locked
out and auxiliary heat (fossil fuel) becomes rst stage until the heating call is satised.
BALANCE POINT CONTROL:
Low Balance Point
When a zone thermostat calls for rst stage heat in dual fuel (fossil fuel) mode and the outdoor temperature is
below the selected low balance point setting, the heat pump compressor is locked out and auxiliary heat (fossil
fuel) replaces heat pump operation. This feature does not apply for standard heat pump operation.
High Balance Point
When a zone thermostat call
above the selected high balance point setting, the auxiliary heat will be locked out. This feature does not apply for
dual fuel (fossil fuel) operation.
EMERGENCY HEAT:
In the event ofaheat pump failure, only one zone thermostat needs to be placed in the Emergency Heat mode.
The Z-600 panel remembers the zone thermostat set in the Emergency Heat mode and treats all calls for heating
from any zone as an emergency heat call. TheLED will be ON to signify that an emergency heat call has
taken place. To reset the system back to standard heat pump operation, take the zone thermostat out of the
Emergency Heat mode. On the next call for heating theLED will be OFF and the panel will resume normal
heat pump operation.
