WHEN INSTALLING THIS PRODUCT...
1. Read these instructions carefully. Failure to follow
them could damage the Arzel®Zoning System
and/or cause a hazardous condition.
2. Disconnect power supply to the HVAC system and the
Arzel®system before making any wiring
connections to prevent danger, electrical shock, and
equipment damage.
3. The Arzel®System is designed for indoor use only.
4. You must touch a grounded metal object before
handling the Arzel®Control Panel to avoid potential
loss of internal programs, due to electrostatic
discharge.
5. Install in ambient temperature between 40° and 150°F,
in a non-condensing area.
6. Complete the Commissioning Checks (p. 8) after
installation is complete.
7. The Arzel®Zoning System controls the HVAC
equipment via a set of dry-contact relays. Be sure that
this is compatible with the equipment operating
specifications.
8. All wiring must comply with all applicable electrical codes,
ordinances, and regulations.
9. Use properly grounded tools. Wear safety glasses and
gloves when drilling or cutting sheet metal ducts, fiber
glass, or any hard objects.
10. Panel contains both AC and DC Terminals.
See Equipment Notes (pp. 6 and 7) for more details.
11. Leave these instructions with installed system for future
use.
1. The Arzel® Zoning System uses a
self-contained, low-pressure air pump to
actuate dampers.
2. All zones have full-function, single-stage,
heating,cooling, and fan capability from all
thermostats.
3. All Zonocity™ systems are both furnace and
heat pump compatible.
4. Use any standard 24VAC thermostat,
Programmable / Non-programmable,
auto/manual changeover/Wireless.
5. Built-in heating, cooling, fan priority system.
6. Emergency heat changeover (manual switch or
remote outdoor thermostat) for heat pump
balance point changeover from heat pump to
backup heat functions.
7. Compressor timed off control (delay on break).
When the compressor is turned off, it cannot
restart for four (4) minutes. This feature allows
the refrigerant pressure to balance before
restarting.
8. “FAN ON HEAT” switch generates fan call
anytimethere is a call for heat: typically used
with hydronic coils or electric heat.
9. Manual Pump Switch (MPS™) is provided to start
the pump manually and open all the zone dampers.
10. Dampers remain open in the last zone that called
for service to take advantage of additional energy
savings from blower timed-off cycles that exist on
all heating and some cooling equipment.
11. LEDs indicate all system operations.
12. A 40VA, 24VAC, self-resetting, plug-in type
transformer is provided to power this Zonocity™
equipment and thermostats.
Caution - Electrical Hazard
Can cause personal injury or equipment damage. Disconnect power to all systems before beginning installation.

GENERAL OPERATION INFORMATION
THERMOSTATS
The Zonocity™ Arzel®Zone Control™ is compatible with any standard 24VAC thermostat: Wireless, Auto/Manual
changeover, Programmable/Non-programmable, Heat/Cool or Fan/Auto/On sub-base switching.
If the thermostat has an adjustable heating anticipator (mechanical thermostats), set it to the shortest or lowest setting.
Heat pump thermostats are required for heat pump operation.
Set up the thermostat to call Y,G in heating: Y,G,O in cooling.
Equipment Notes
The mini-pump, located in the bottom of the enclosure, runs anytime there is a call from any thermostat. It
creates both pressure and vacuum. On a call from any thermostat, the logic board will energize the solenoid valve(s)
for non-calling zone(s) and make the appropriate dry contact relays to start the HVAC equipment. 2
3
1
Dampers open with vacuum.
Dampers close with pressure.
The logic board is designed for heating to have priority over cooling and cooling
to have priority over fan operation.
When all thermostats are satisfied, the air pumps, the HVAC equipment, and the
solenoid air valves are de-energized. Dampers will remain in whatever position
they were in when the last thermostat call was finished. Leaving the dampers
open in the last zone served allows the HVAC system to utilize the residual
energy in the system at the end of both the heating and cooling cycles.
The Manual Pump Switch (MPS™) is provided to run the pump continuously.
Turning the MPS switch to ON manually makes the pump relay and the pump
starts, driving all dampers open. This creates a failsafe. If the board fails the
dampers can be easily opened and the system run from one thermostat.

Quick Start Instructions
The Arzel®Zoning Zonocity™ Zoning Systems™ are easy to install. Please read these instructions
completely to ensure that you understand the system. Pay special attention to the Control Panel
Section on Page 2. This QuickStart page has been provided as an installation overveiw with
references to more detailed information other places in this manual.
1 Install Dampers/Run
Tubing
Dampers install directly into existing
trunk. Dampers install with the tubing
port pointing toward the
equipment. Install one tubing run for
each zone. Use a tee for multiple
dampers on one zone. Arzel®
recommends using a different color
tube for each zone.
5 Connect Transformer
Use 18 gauge - 2 conductor solid wire to connect R and C on the Power Terminal Strip to the mounting screws on the
40VAC self-resetting, plug-in transformer supplied with the Arzel®Zoning System. Plug in the transformer to any
standard 120VAC receptacle.
6 Test the System
See commissioning procedure on pg. 8.
3 Connect thermostats
Install a thermostat for each zone. Use 18 gauge, multiconductor, solid
thermostat wire to connect the thermostats to the control panel. Connect
R,W,Y,G,O, and C as appropriate to the zone terminal strips along the upper
right side of the Zone Control Board. Note which thermostats are connected to
which zones on the zone layout label on the side of the panel.
4 Connect Equipment
Use 18 gauge, multiconductor,
solid thermostat wire to connect
the HVAC Outputs along the left
side of the Zone Control Board to
the HVAC Equipment. Connect
R,W,Y,G, O, and C as
appropriate to the equipment as if
it were a thermostat.
2 Hang Panel
Panel must be hung in a
non-condensing area where
temperatures will not normally exceed
100oF. DO NOT MOUNT PANEL ON
DUCTWORK OR THE HVAC
EQUIPMENT. The best method is to
attach a piece of 3/4” plywood to the
block wall. Hold the panel level to the
wall, mark the positions of the upper
mounting holes. Drive two screws to the wall leaving the heads at least 1/2”
out. Set the panel over the screws. Drive two screws into the lower mounting
holes. Tighten the upper screws.

IF ALL ELSE FAILS...
1. Turn the Arzel®power switch to OFF.
2. Disconnect the thermostat wires from any zone and connect them to the HVAC OUTPUT terminals.
3. Turn the MPS™ switch ON, this will open ALL zone dampers.
The HVAC system will work without the benefit of the zoning system. The heating and air conditioning equipment is now
controlled by that thermostat. All dampers will stay open. If the HVAC system does not work in this configuration, you
probably have a wiring, thermostat or other equipment problem.

Troubleshooting Matrix
FAN CHECK-OUT
1. Set all thermostats to the OFF position and all fan switches to AUTO.
2. Turn the HVAC system and the Arzel®system PWR switches to ON. The LED light next to the switch will illuminate.
3. Turn the Zone 1 thermostat fan switch ON. The S1 indicator, the Fan output (G) and Pump LED lights will
illuminate. The fan in the HVAC system will turn on. The pressure and vacuum pump will position all the dampers.
Check the air flow at all register outlets to determine that only Zone 1 dampers are open and all other dampers are
closed.
4. Follow the above procedure for all other zones.
HEATING & COOLING CHECK-OUT
1. Set all thermostats to the OFF position and all fan switches to AUTO before starting heating system check out.
2. Set Zone 1 thermostat to the HEAT position and turn thermostat up so that the thermostat is calling for heat. The
S1 indicator, the W output, and the pump LED lights will illuminate. The pressure/vacuum pump will position
all the dampers. Check to see that the heating circuit is energized.
If heat pump is installed, check operation of Emergency Back-up heating. Turn the thermostat down until the
thermostat is satisfied. The LED lights will go out and the pump will stop. Dampers will remain open in the last
zone that called. For heat pump, LED indication will be Y & G.
3. Set thermostat for Zone 1 to the COOL position. Turn thermostat down so that the thermostat is calling for cooling.
The S1 indicator, the Y and G output and the pump LED will illuminate. The pressure/vacuum pump will
position all the dampers. Check to see that the compressor contactor is energized. For heat pump, LED
indication will be Y, G & O.
4. Place Zone 1 thermostat in the OFF position.
5. Follow the above procedure for all other zones.
