CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment circuitry.
When line voltage is applied to the AQ251 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.
4 PROGRAM AND CONFIGURE THE
CONTROL PANEL
Only two steps are required to set up the AQ251 Series Control
Panel:
1. Check the program settings for the Control Module:
Operation of the AQ251's Control Module is set by the
menu selections accessible through the Control
Module’s LCD screen. See “AQ251 – System
Programming” on page 16 for instructions.
2. Check the DIP switch settings for each Zoning Module.
Control Panel Defaults
Operation of the AQ251 Control Module is set by the menu
selections accessible through the Control Module’s LCD
screen. See “AQ251 – System Programming” on page 16 for
instructions.
The AQ251 Control Panels are shipped from the factory with
pre-defined values for all program settings. These factory
default settings are commonly used by hydronics contractors
across North America. Usually, most of the settings only need
to be checked by the installing contractor to make sure they
are suitable for the job, rather than having to input all the
settings from scratch.
Although these factory default values for the Control Module
and each Zoning Module are suitable for many installations,
Honeywell recommends that they be reviewed, and changed
as necessary, to get optimal performance of the hydronic
system controlled by the AQ2000 Series products.
Zoning Module DIP Switch Location
The AQ15540B (pump Zoning Module) and AQ15740B (valves
with end switches Zoning Module) both have DIP switches in
8-switch banks and are concealed behind snap-on covers, as
shown in Fig. 20.
