Warning Read all of the instructions before proceeding

Can cause electrical shock or equipment damage. Always turn off power to the heating/air

conditioning system prior to installing or adjusting the expandable zone panel. Wire the entire

panel before applying transformer power.

This panel is designed for professional installation, and is to be installed and conﬁgured as

described in this manual. Any other use is not recommended and will void the warranty.

Install disconnect and overload protection on circuits as required by code authorities having

jurisdiction for the installation.

Suitable Mounting Locations

Mount the Zone Panel near the HVAC equipment. The panel can be mounted in any orientation on a wall,

stud, roof truss, or the return-air plenum. For appearance, mount the panel level. Remove the panel cover

and use the base as a template to drill mounting holes (see Figure 2). Attach the panel with appropriate

screws. Use mounting anchors as needed for drywall or plaster installations.

Wiring the Panel

Always turn off power to the heating/air conditioning system prior to installing or adjusting the Zone Panel. Wire the

entire panel before applying transformer power. Use the following general wiring instructions for all systems. Speciﬁc

wiring will vary depending on the equipment and type of system (conventional or heat pump). NOTE: Up to 2 wires

can be inserted into each terminal. To release wires, press down on top of wiring terminal and gently pull out wire(s).

Damper Wiring

3.1

Always turn off power to the heating/air conditioning system prior to installing or adjusting the zone panel. Wire

the entire panel before applying transformer power.

Use the following general wiring instructions for all systems. Speciﬁc wiring will vary depending on the equipment

and type of system (conventional or heat pump).

Install the system dampers using the instructions provided by the manufacturer. Connect the dampers to the zone

panel as shown for either a 2-wire or 3-wire damper. The sum of all dampers powered by the zone panel should

not exceed 100 VA at 24 VAC. Use a slave relay if additional damper power is required.

ALWAYS PROVIDE DISCONNECT AND OVERLOAD PROTECTION AS REQUIRED

3.2

Install the system thermostats using the instructions provided by the manufacturer. Connect the thermostats to

the zone panel as shown. Do not mix conventional and heat pump thermostats on the same system. You can mix

single stage and multi-stage thermostats as long as they are all conventional or heat pump.

3.4

Install the transformer using the instructions provided by the manufacturer. Size the

transformer to the damper requirements. The zone panel has built-in, self-resetting

fuses. The maximum damper power per panel is 100 VA at 24 VAC. Connect the

transformer to the zone panel as shown.

NOTE: Additional dampers or dampers with a higher current draw will require the

use of a separate slave relay.

relay installed.

Conﬁguration

Use the following instructions to conﬁgure the zone panel. The zone

panel is factory set for a 1 Heat / 1 Cool

Conventional System with Conventional Thermostats (Heat Call on W, Cool Call on Y). If the zone panel is installed

on other systems, you will need to make conﬁguration changes described in this section.

To start conﬁguration:

1. Press SETUP and hold for 3 seconds.

2. The panel backlight will turn on and the display

will change.

3. Change setting if needed by pressing SELECT.

4. To save and advance to the next setting press

the NEXT button.

5. Repeat steps 3-4 as necessary.

6. Press HOLD FOR BACK for 3 seconds to go back a step.

7. Press HOLD FOR EXIT for 3 seconds to exit setup menu.
