Test And Check Out The Installation - Honeywell AQ25A Series Technical Reference Booklet

5 TEST AND CHECK OUT THE
INSTALLATION
Startup
IMPORTANT
Apply power to the AQ250 Control Panel only after all
of the AQ2000 SERIES components (Control Panel,
thermostats, sensors, Zoning Modules/Panels) have
been connected to the other equipment in the
hydronic heating system (boiler, zone valves or
pumps, DHW, Aquastat, etc.).
When powered, the AQ250 Control Panel begins its start-up
routine, establishing communication with all other AQ2000
Series components on the AQUATROL network.
Auto Test
This section describes the Auto Test functions of the Control
Module and the Zoning Panel(s).
A) Auto Test– AQ15000B Control Module
Auto Test operation enables the installer to test the system
installation by sequentially activating all of the Control Module's
outputs for 15 seconds each. Each step of the Auto Test
routine may be paused or skipped by pressing the Test button,
which is located above the DIP switches on the AQ15000B
Control Module.
STATUS LEDS
Every status light (ZR, BOILER pump, AUXiliary pump, DHW
pump) will be turned on for 15 seconds when its corresponding
output is energized during Auto Test.
CONTROL MODULE DIAGNOSTIC LED
This LED, which is labeled Diagnostic and is located above the
DIP switches on the AQ15000B Control Module, is used by the
AQ250 to communicate diagnostic data to the user:
• Constantly ON indicates that the unit is working properly.
• Constant, fast blinking indicates that the unit is in the Auto
Test mode.
• Constant, slow blinking indicates that Auto Test mode has
been paused.
• Coded blinking is used to communicate an error code to the
user. Refer to the Troubleshooting section of these
instructions for an explanation of these codes.
NOTE: The Diagnostic LED is OFF when the AQ250 Control
Panel is not powered.
If this is the first time the AQ250 has been started:
1. Remove the front cover of the AQ250 by loosening the
4 captive slot-Phillips screws.
2. Remove the AQ15000B Control Module's DIP switch
cover (refer to Figure Fig. 20 on page 14 for the DIP
switch cover location)
3. Check to make sure that the LED, labelled Diagnostic, is
steadily illuminated (no blinking).
4. To begin the Auto Test, press the Test button until you
feel a click. The AQ250 now begins the Auto Test routine
and the Diagnostic LED on the AQ15000B Control
Module blinks quickly.
AQ250 SERIES HYDRONIC CONTROL PANELS
5. Pressing the Test button at any time during the Auto Test
routine pauses the routine indefinitely. While paused, the
Diagnostic LED blinks slowly.
6. Pressing the Test button while the Auto Test routine is
paused advances the routine to the start of the next step
in the routine (testing the next output) and the Auto Test
routine resumes its test procedure.
7. When the Auto Test routine is completed, the Diagnostic
LED returns to a constant ON status (no blinking).
8. To test each of the zone outputs (pumps or valves)
individually, proceed to "B) Auto Test– AQ155/AQ157
Zoning Modules" to run the Auto Test feature for each
AQ155 / AQ157 Zoning Module attached to the
AQ15000B Control Module.
SEQUENCE OF OPERATION—AQ15000B CONTROL MODULE
1. When the Test button is pressed, ALL space heating
zones connected to the Control Module are energized
and remain energized for the duration of the Auto Test
routine
2. At the same time, the Diagnostic LED on the AQ15000B
Control Module begins to blink quickly, the ZR relay is
energized for 15 seconds, then the relay shuts off.
3. Next, the BOILER relay is energized for 15 seconds,
then shuts off.
4. Next, the AUX relay is energized for 15 seconds, then
shuts off.
5. Next, the DHW relay is energized for 15 seconds, then
shuts off.
6. Next, the Boiler T-T dry contacts are energized for 15
seconds, then re-opened.
7. Then the AQ15000B exits the Auto Test routine and the
Diagnostic LED on the Module returns to steady
illumination (no blinking).
B) Auto Test– AQ155/AQ157 Zoning Modules
Auto Test operation for Zoning Modules enables the installer to
test all zones wired to the Zoning Module by sequentially
activating the equipment connected to each zone output (pump
or valve) for 15 seconds. Each step of the Auto Test routine
may be paused or skipped by pressing the Test button.
ZONING MODULE DIAGNOSTIC LED
The LED, which is labeled Diagnostic and is located above the
DIP switches on the AQ155/AQ157 Zoning Modules, is used
for communicating diagnostic data to the Installer.
Refer to "Troubleshooting" on page 19 for a description of the
Diagnostic LED error codes (blinking rates).
NOTE: The Diagnostic LED is OFF when the AQ155/AQ157
Zoning Module is not powered.
If this is the first time the AQ250 Control Panel has been
started:
1. With the front cover of the AQ250 Control Panel
removed and set aside, remove the AQ Zoning Module
DIP switch cover (refer to Figure Fig. 20 on page 14 for
the DIP switch cover location).
2. Check to make sure that the LED, labelled Diagnostic, is
steadily illuminated (no blinking).
3. To begin the Auto Test, press the Test button until you
feel a click. The AQ155/AQ157 Zoning Module now
begins the Auto Test routine, and the Diagnostic LED on
the Zoning Module blinks quickly.
