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.
