Step 6 – Connection To Line Voltage
Power
Connect the N and L line voltage inputs of the primary on
the AQ250 transformer to the electrical distribution panel
and power up the Control. A service switch should be
installed on the hot (L) lead to the distribution panel.
If multiple Zoning Modules are connected to the AQ250
Control Panel, the line voltage wiring can either be run
directly from the N and L terminals on the primary of the
transformer to each Zoning Module (Fig. 18 on page 13),
or run in a daisy chain from the N and L terminals of one
AQ2000 module to the N and L terminals of the next
AQ2000 module (see Fig. 19 on page 13).

AQ250 SERIES HYDRONIC CONTROL PANELS
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
When line voltage is applied to the AQ250 Control
Panel and the front cover of the Panel is removed,
there is a risk of electrocution. Be careful to avoid
contact with the line voltage (N and L) terminals,
either with your fingers or with metal tools (such as
a screwdriver) when power is applied to the Control
Panel.
