Control Panel to mark mounting holes for panels
2. Install two top screws, mount the panel, and install the
two lower screws.

Mount and Wire Thermostats in the Zones
Install the thermostats on the walls in the zones that are to be
controlled by the AQ251 Control Panel.
When using AQ1000 thermostats refer to the installation
instructions (form #69-2005) included with the AQ1000
thermostats.
If not done already, run low voltage thermostat wire (24 gauge
or heavier) from the thermostats back to the Zoning Modules
connected to the AQ251 Control Panel.

Mount Expansion Zoning Panel(s)
If there are Expansion Zoning Panels to install, mount them to
the wall now:
1. Remove wire channel plugs from the AQ251 Control
Panel and any Expansion Zoning Panels (see Fig. 3).
2. Mount Expansion Zoning Panel on the right-hand end of
the AQ251 Control Panel. Install two top screws of the
Expansion Zoning Panel, ensuring it is level with the
adjoining Control Panel, and install two lower screws.
3. Reverse wire channel plugs and re-insert them into their
slot, to form a wiring channel between the Control Panel
and the Expansion Zoning Panel (see Fig. 3) and to
connect the two panels together.
4. Repeat steps 1–3 for any additional Expansion Zoning
Panels.
NOTES: If not otherwise specified, low voltage wiring should
be run with 18 gauge thermostat wire and line voltage
wiring should be run with 14 gauge wire.
AQUATROL® line voltage screw terminals are only
approved for use with 22 to 12 gauge copper
conductors.
