Your zoning system is simple to operate and requires no maintenance.
The system will allow you to increase your comfort by directing conditioned air to separate areas (zones)
based upon each zone's thermostat setting. It provides the opportunity to conserve energy by adjusting the
thermostat setting in unoccupied areas to energy saving levels.
To operate the system, just set or program each zone's thermostat to your desired comfort and/or set-
back settings. When there is a call for heating or cooling from any zone, the appropriate heating or cooling
equipment will be turned on. The dampers in zones not requiring heating or cooling will close and the
conditioned air will be directed to the calling zone(s) until the thermostat is satisfied.
When there is not an active call for heating or cooling, you may circulate air in individual zones by selecting
the “Fan ON” function on each individual thermostat. The dampers in zones with the fan set to “Auto” will
close.
Please feel free to learn more about the installation and operation of the Arzel MPS Series by reviewing
this entire manual. Consult your installing contractor with any questions regarding system operation. If
questions are still unresolved, you may call Arzel’s Technical support for homeowners from 8 AM - 5 PM
EST from Monday-Friday. Please have your system serial number available when you call. Your installing
contractor can reach Arzel Technical support Monday-Friday 8 AM - 9 PM EST. The Arzel Technical
support phone number is 1-800-611-8312.

1. Disconnect the power supply to the HVAC system and the zoning system before making any
wiring connections to prevent the danger of electrical shock or equipment damage.
2. Be sure the HVAC manufacturer’s operating specifications are compatible with the Arzel zoning
system.
3. All wiring must comply with applicable electrical codes, ordinances and regulations.
4. Use properly grounded tools, safety glasses and gloves when drilling or cutting sheet-metal ducts,
fiberglass or any hard objects.
1. The Arzel system is designed for indoor use only.
2. You must touch a grounded metal object before handling the control panel to avoid potential loss of
internal programs due to electrostatic discharge.
3. Install in ambient temperature between 40oF and 140oF in a non-condensing area.
4. Check all system operations after installation is complete.
5. The damper blade gently wipes the inside of the ductwork. Insert a sleeve inside any berglass, or
abraidable ductwork, so the blade does not abrade the materials into the air.
6. Leave these instructions with the installed system for future use.
7. There are both AC and DC terminals on the circuit board. Do not intermingle wires.
GENERAL SYSTEM OPERATION:
When all thermostats are satisfied, the air pump, 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.
INSTALLATION PRECAUTIONS
Read these instructions carefully.
Failure to follow them could damage the Arzel® Zoning System
and/or cause a hazardous condition.

THERMOSTATS
The 200 Series™ 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. Regardless of equipment type, if your equipment energizes the reversing valve
in Heating mode utilize the "B" terminal on the HVAC outputs. See page 6 for wiring diagram.
LEAVING AIR TEMPERATURE CONTROLS
The 200 Series™ does not monitor the temperature of the air in the ductwork. If positive control is
desired, additional temperature controls must be installed.
1. Install Dampers/Run Tubing
Dampers install directly into new or existing ductwork. Orient the tube connection port so it is pointing upstream
(toward the equipment). Install one main tubing run for each zone. Use connection “T’s” for multiple dampers
in a zone. Arzel recommends using a different color tube for each zone. Note: Dampers should not be
concealed behind a permanent barrier such as drywall without an access panel.
2. Mount Control Panel
The control panel must be mounted vertically on an exterior wall to reduce noise. The wall must also be located
in a non-condensing area where temperatures will not normally exceed 140° F. DO NOT MOUNT PANEL ON
DUCTWORK, HVAC EQUIPMENT, STAIRWELL, or BEDROOM WALLS. The best method is to attach a
piece of ¾ plywood to an exterior stud wall or foundation. Hold the panel level on the wall and mark the positions
of the upper mounting holes. Drive two screws into the wall leaving the heads at least ½” out. Set the panel over
the screws. Drive two screws into the lower mounting holes. Tighten the upper screws. Note: Prior to making
electrical connections, touch a mechanical ground to discharge static electricity.
3. Connect Thermostats
Install a thermostat for each zone observing the terminal designations. Use 18 gauge, multi-conductor, solid
thermostat wire to connect the thermostats to the control panel. When using a heat pump thermostat “O”
must be set to energize for cooling calls. Document the location of each thermostat connected to each zone
on the “Zone Layout” label on the side of the panel.
4. Connect Equipment
Use 18 gauge, multi-conductor, solid thermostat wire to connect the HVAC outputs located along the top of
the zone control panel to the HVAC equipment. The “C” terminal are for connection between the furnace/air
handler transformer and the common circuit of the heat pump/air conditioner controls.
5. Connect Transformer
Use 18 gauge, 2-conductor solid wire to connect the R and C power input terminals 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. Note: The provided transformer has an auto-resetting internal
overload to protect against low voltage shorts. Additional surge protection may be required. The Use of
transformers not approved by Arzel may void warranty coverage.
