Z-1600 MODULATING ZONE CONTROL SYSTEM
OVERVIEW
The Z-1600 Comfort System™ is a commercial zone control system that allows a single
HVAC unit to have up to 16 individual zones. Each zone is controlled by its own space thermostat
and a modulating damper. When a majority of zones are calling for cooling, the system operates in
the cooling mode. The Z-1600 controls up to two stages of cooling to maintain a cooling discharge air
setpoint. If a majority of zones are calling for heating, the system changes from the cooling mode to
the heating mode. The Z-1600 then controls up to two stages of heating to maintain a heating
discharge air setpoint. When the number of heating and cooling requests are equal, the system
satisfies the cooling request first.
Comfort System™ zone dampers are available in round and rectangular, as well as VAV
diffusers. All three types are controlled by a P+I modulating thermostat that controls the mode of
operation based on duct temperature. The thermostat controls the zone damper to maintain room
temperature in both cooling and heating modes. When the zone temperature falls below the heating
setpoint, the zone damper sends a signal to the Z-1600 control panel requesting heat. When the
zone temperature rises above the cooling setpoint, the zone damper sends a signal to the Z-1600
control panel requesting cooling. These signals are used to determine the mode (heating or cooling)
of the HVAC unit as described above. The zone thermostat heating output can also be used to
control auxiliary baseboard, duct, or ceiling radiation heat.
A bypass damper is installed between the supply and return air duct to maintain the proper
system static pressure. Bypass dampers are available in both electronic and barometric type.
Electronic bypass dampers are recommended for systems with static pressure of 0.75” w.c. and
over. Barometric bypass dampers are recommended for systems under 0.75” w.c. of static pressure.

WITH AUTO CHANGEOVER
DISCHARGE AIR SENSOR
A discharge air sensor is supplied with each
thermostat. The purpose of the discharge air
sensor is to select the mode of operation of the
damper. If the discharge air temperature is
above 72° F, the damper will open on a call for
heating. If the discharge air temperature is
below 72° F, the damper will open on a call for
cooling.
TESTING DISCHARGE SENSOR
DISASSEMBLING THERMOSTAT
To separate the thermostat from the
backplate, hold the front of the thermostat
with right hand. Use the thumbnail of left
hand to hook the extremely small rounded
tab located on the top edge of the
thermostat backplate and pull apart.
PUSH BUTTON FUNCTIONS
Press the ON button to activate the
thermostat.
Press the OFF button to deactivate the
thermostat. This will also drive the zone
damper closed.
The C/F button switches the display
between Fahrenheit and Celsius.
THERMOSTAT DISPLAY
The thermostat continuously displays room
temperature.
If the thermostat calls for heating, “HEAT”
will flash on the display. If the thermostat
calls for cooling, “COOL” will flash on the
display.
Setpoint limits are factory preset from
68° F to 76° F. It is recommended that
these setpoint limits not be exceeded.
Zone Control Made Simple™
Disconnecting the discharge air sensor will put
the thermostat in the cool mode. Shorting out
the sensor will put the thermostat in the heat
mode.

When the room temperature is 1.5 degrees below setpoint the thermostat will close the R to W contacts on the
actuator board and signal the Z-1600 panel that there is a heating call.
When the room temperature is 1.5 degrees above the setpoint the thermostat will close the R to Y contacts on
the actuator board and signal the Z-1600 panel that there is a cooling call.
DAMPER NOTES:
To balance the HVAC system, remove each zone thermostat from its subbase and jumper terminals 1 and 4 to
drive dampers open.
The actuator board is located on the side of the damper actuator and is wired at the factory.
Each zone damper requires 3VA.
The space thermostat will control up to 6 damper actuators wired in parallel.
If the discharge air temperature at the damper is warmer than 72 degrees, the zone damper operates as a
heating d a m p e r .
If the discharge air temperature at the damper is below 72 degrees, the zone damper operates as a cooling
d a m p e r.
The Z-1600-T zone thermostats have temperature limits set at 68 degrees and 76 degrees and should not be
changed.
Z-1600- PANEL NOTES:
Use standard 18 gauge thermostat wire.
Run three wire cable from the panel terminals (R,Y,W) to each individual zone damper
actuator board.
Panel requires a 24 VAC 40VA transformer.
Locate discharge air sensor 3 feet down stream in trunk line.
“Speed up jumper” shortens all the time delays on the control panel (use for testing only).
“Number of calls required resistor” determines the number of zones that must be calling
in order for he system to bring on the heating or cooling equipment.
Time clock contacts are closed during occupied cycle.

This system generally does not require any adjustments.
A red light indicates the zone is calling for heating. A green light indicates the zone is callinbg
for cooling.
The number printed on the “Call Required Resistor” indicates the number of like calls that must
take place before the heating or cooling equipment will start.
MAJORITY WINS
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, the system will be in the cooling mode.
This is referred to as Cooling Priority.

Z-1600 COMFORT SYSTEM™
DESIGN AND INSTALLATION NOTES
•
Extra consideration should be given when applying any zone control system to a building that
requires large amounts of cooling in the core zones during cold weather. Consider adding
auxiliary heat to external zones or using one system for the core zones and one system for the
external zones.
•
It is recommended that the system installation be limited to 50 tons of capacity. Rooftop units
with economizers and relief dampers are strongly recommended for buildings with core
cooling loads.
•
Oversizing of the HVAC equipment is not recommended. In most cases, it is better to slightly
undersize the equipment.
•
It is recommended that the HVAC equipment have two stages of heating and two stages of
cooling.
•
The pressure drop through the zone dampers is negligible and should not be a factor when
sizing branch duct runs.
•
Zone dampers are rated up to 2” w.c. of static pressure and up to 2,000 fpm.
•
Zone dampers should be installed as far back from discharge air grille as possible. Flex duct
should be used for the last 5 feet of each branch run.
•
Bypass dampers should be sized for 90% of the total system air flow at 2,500 fpm.
•
The Z-1600 Comfort System™ panel should be located near the center of the building to keep
wire runs as short as possible.
•
DO NOT mount the Z-1600 Comfort System™ panel on or inside the rooftop unit.
•
Use a separate 24 VAC, 40 VA transformer for the Z-1600 Comfort System™ panel.

Z-1600 COMFORT SYSTEM™
WIRING DETAILS
GENERAL NOTES
Install the Z-1600 Comfort System™ control panel on a flat surface near the HVAC equipment. The panel should be
installed in a dry, clean location approximately 60 inches from the floor. Do not install the control panel on or inside a
rooftop unit.
24 VOLT POWER
The control panel requires a 24 Volt, 40VA transformer. Do not power the control panel from the transformer in the HVAC
equipment. Connect 24 Volts to the terminals labeled 24 VAC INPUT POWER on the interface board. 18-2 thermostat wire
is recommended.
DISCHARGE AIR TEMPERATURE SENSOR
The control panel requires a discharge air temperature sensor. Mount the sensor 26 inches from the HVAC equipment in
the supply duct. Connect the sensor to the terminals labeled DISC TEMP SENSOR on the interface board. 18-2
thermostat wire is recommended.
HVAC UNIT
The control panel is wired to the HVAC equipment in the same way as a standard 2-stage heat / 2-stage cool thermostat.
Connect the HVAC equipment to the terminals labeled HVAC UNIT TERMINALS on the interface board. 18-8 thermostat
wire is recommended.
R, Y, AND W ZONE DAMPER TERMINALS
The control panel requires a heating and cooling contact closure from each zone damper. Connect terminals R, Y, and W
from each zone damper to the terminals labeled R, Y, and W on the interface board. 18-3 thermostat wire is
recommended.
TIME CLOCK, NIGHT STAT AND OVERRIDE TIMER (OPTIONAL)
The control panel has an optional input for a time clock, night stat, and override timer. To install a time clock, remove the
factory installed jumper between the two terminals labeled TIME CLOCK CONTACTS. Wire the time clock using the
contacts that are closed during the occupied mode. A normally open night stat and override timer can be wired in parallel
with the time clock for unoccupied temperature control. 18-2 thermostat wire is recommended.
PROGRAMMING RESISTOR
The control panel is equipped with a “2 calls required” resistor factory installed on the interface board. This resistor
determines the number of zones that must be calling for heating or cooling before the system will change modes. Resistor
for 1 through 4 “calls required” are also shipped with the control panel. Install the appropriate resistor in the terminals
labeled # CALLS REQUIRED RESISTOR.
SPEED-UP JUMPER
The control panel is equipped with “speed-up jumper” terminals. Installing a jumper between the two terminals labeled
SPEED-UP JUMPER will reduce the time delays between stages and between modes of operation. The standard time
delay between stages and between modes is 15 minutes. With the jumper installed, the time delays are reduced to 3
minutes.The speed-up-jumper is for commissioning only. Do not leave the jumper installed after the unit is commissioned.
MICROPROCESSOR BOARD
The microprocessor board requires no wiring, adjustment, or maintenance.

Z-1600 COMFORT SYSTEM™
CONTROL PANEL SPECIFICATIONS
APPLICATION:
The model Z-1600 Comfort System™ is a commercial zone control system that allows a single heating and cooling unit to
have up to 16 individual zones. Each zone is controlled by its own space thermostat and motorized damper. If a majority of
zones are calling for heat, the system will operate in the heating mode. The two stages of heat will be cycled to maintain
the heating discharge air setpoint. If a majority of zones are calling for cooling, the system will operate in the cooling mode
and the two stages of cooling will be cycled to maintain the cooling discharge air setpoint. If the number of zones calling for
heating and cooling are equal, the system will operate in the cooling mode first. This is known as Cooling Priority. Each
zone damper or diffuser will modulate, based on zone and discharge air temperature, to maintain the individual zone
temperature setpoint. A barometric or electronic bypass damper will modulate to maintain the duct static pressure.
