AQUATROL Zone Synchronizing
Injection/Mixing Boiler Reset Controls
AQ252
APPLICATION
The AQ252 series of AQUATROL® Injection/Mixing Boiler
Reset Controls provides simplified, energy-efficient
outdoor temperature compensated control of a high-
temperature boiler loop and a lower temperature mixed
loop in residential hydronic heating systems. The AQ252
easily converts a single-zone heating system into a room-
by-room comfort control system, or upgrades a basic,
relay-logic zoning system to intelligent Zone of Greatest
Demand control, with outdoor reset for increased energy
efficiency and with reduced boiler cycling. The boiler
controls of the AQ252 can ensure ample supply of hot
water for both space heating and priority generation of
domestic hot water for bathing, dishes and laundry.
When AQ1000 communicating thermostats are used with
the AQ252 Zoning Modules, they can use the same wiring
as existing thermostats. Night setback operation can be
programmed from the AQ252 panel.
WARNING
Risk of electrical shock.
Can cause severe injury, property damage or
death.
Only trained, experienced, licensed service
technicians should service this Control Panel. The
front cover of the AQ251 Control Panel should not
be removed, as this will expose the user to
potentially dangerous line voltage (120V)
electricity.
Congratulations!
The AQUATROL AQ252 installed on your heating system is
the most powerful, yet user-friendly hydronic heating
control system available on the market for residential and
light commercial installations.
This document contains all the information you need to
program the comfort settings of the AQ252 and to
customize its operation for your home or business. For
detailed information on the operation of this control,
please consult the trained hydronic heating professional
that installed the AQ252 control.

Programming Instructions
Program the AQ252 by using the keypad and LCD display
to select parameters from the User Menu. Refer to
Fig. 1 on page 2 for an illustration of the LCD screen and
keypad.
NOTE: The figures in “User Menu Structure” on page 8
provide a graphical layout of the AQ252’s User
and Installer menus.
When a new AQ2000 component is connected on the
AQUATROL network, it will be seamlessly integrated in the
system after a few seconds. If one or more components are
disconnected or stop providing data to the network, a
message will appear on the System Status display until
the fault is corrected.
User Menu Overview
The User Menu is intended for use by the building owner
to choose the LCD display preferences, Zone Settings
(including setpoint temperatures and setback times for
each zone), and temperatures for the WAKE, LEAVE,
RETRN (return), and SLEEP programs.
The Home Page and User Menu allow the building owner
to:
• View the status of the system.
• Set up preferences for how the system information is
displayed.
• Set target temperatures for each zone (requires
AQ1000 thermostats).
• Program times of the day when the system will set back
the temperatures for all zones (requires AQ1000
thermostats).
NOTE: If there are any problems with the system’s opera-
tion, the AQ252 displays error codes on the Sys-
tem Status display of the LCD panel. For details
on these, refer to “Troubleshooting” on page 6.
TO ACCESS THE USER MENU:
Press the Menu button on the keypad at any time to
access the User Menu.
User Menu Settings
The User menu has five sub-menus.
• “System Status”
• “Preferences/Time”
• “Zone Settings (requires AQ1000 thermostats)”
• “Program Settings”
• “Statistics” on page 5
To make changes to the parameter settings in the User
Menu, refer to “LCD Display Navigation” on page 3.
SYSTEM STATUS
This is a detailed list of activities going on in the heating
system (e.g., call for heat, DHW disabled), and provide the
building owner with a quick snapshot of the heating
system’s operation, primarily for purposes of
troubleshooting and system diagnostics.
PREFERENCES/TIME
The preferences that the building owner can change in
this sub-menu are:
— The temperature scale for the display (Fahrenheit
or Celsius) for both the AQ252 control’s LCD and
the zone thermostats.
— The time display in 12 hour (e.g., 7:00 PM) or 24
hour format (e.g., 19:00).
— Date and time of day – allows building owner to
reset day and time of day in the event of a power
outage of more than 4 hours (refer to Trouble-
shooting section).
— The Home Page display view, Simple or Detail. The
factory default is Detail.
— The LCD Backlight – illuminated permanently (ON)
or set to automatically turn off backlight after 1
hour (AUTO).
POWER FAILURE
If a power disruption lasts for more than 4 hours, the
message PLS SET DAY/TIME displays and optionally, the
AQ252's backlight flashes repeatedly. This displayed
message continues until the DATE and TIME OF DAY are
updated. See “Power Disruption Greater Than 4 Hours” on
page 6.
ZONE SETTINGS (REQUIRES AQ1000 THERMOSTATS)
Settings in this sub-menu define:
— The temperature setpoints (target temperatures)
for each zone in the heating system.
— The temperature setback for each zone in the heat-
ing system. This is the desired temperature drop
when the heating system enters the setback pro-
gram SLEEP or LEAVE.
— The maximum and minimum setpoints that can be
entered by a user at a thermostat screen for each
zone.
— Whether each zone can be set independently by the
AQ252 (i.e., some zones can be locked while others
are unlocked) depending on whether or not the
keyboard on a thermostat is locked. When locked,
no changes can be made to a zone’s setpoint tem-
perature through the thermostat. Changes can still
be made through the Zone Settings menu on the
AQ252 control panel.
PROGRAM SETTINGS
Using the Program Settings sub-menu, the building owner
can define the time of day when the entire heating system
will change programs (e.g., from SLEEP to WAKE).
The AQ252 has provision for four different schedule
periods per day. They are defined as WAKE, LEAVE, RETRN
(return), and SLEEP:
WAKE: Period when you awaken and want your home at
a comfortable temperature.
LEAVE: Period when you are away from home and want
an energy-saving temperature.
RETRN: Period when you return home and want your
home back to a comfortable temperature.
SLEEP: Period when you are asleep and want an
energy-saving temperature.
There are three modes of operation – Automatic, Occupied
and Unoccupied:
AUTO: In AUTO mode, the AQ252 follows the WAKE,
LEAVE, RETRN, and SLEEP programs.

AQUATROL ZONE SYNCHRONIZING INJECTION/MIXING BOILER RESET CONTROLS
569-1990—03
OCC: In OCC mode, the AQ252 holds the temperature
of OCCUPIED programs (WAKE and RETURN). This
might be used if the occupancy pattern of the building
changes temporarily, requiring the temperature to be at
a comfort level 24 hours/day.
UNOCC: In UNOCC mode, the AQ252 holds the
temperature of UNOCCUPIED programs (LEAVE and
SLEEP). This might be used if the building will be
unoccupied for an extended period of time, such as a
vacation period.
There are two ways to set the schedule program times for
WAKE, LEAVE, RETRN, and SLEEP:
— One day at a time
— All days at the same time
1. One day at a time programming:
• Select EDIT DAILY from the Program Settings
sub-menu.
• A list of four program times per day displays,
showing the factory pre-set times for all
programs:
MON WAKE 6:00A
MON LEAVE 8:00A
MON RETRN 4:30P
MON SLEEP 10:00P
TUE WAKE 6:00A
TUE LEAVE 8:00A
TUE RETRN 4:30P
TUE SLEEP 10:00P
…
SAT WAKE 6:00A
SAT LEAVE --:--
SAT RETRN --:--
SAT SLEEP 10:00P
SUN WAKE 6:00A
SUN LEAVE --:--
SUN RETRN --:--
SUN SLEEP 10:00P
• Any of the times can be changed by scrolling to
that line and pressing the + or – button until the
desired program time is displayed.
2. Programming all days at the same time:
• Select EDIT ALL DAYS from the Program Settings
sub-menu.
• A sub-menu displays where you can change the
WAKE program time for all days, the LEAVE
program time for all days, etc.
• When all four programs have been set, select the
COPY TO ALL DAYS option. This displays the
prompt: COPY TO ALL DAYS - ARE YOU SURE?.
Select Yes by positioning the indicator arrow at
YES and press the OK button.
• Next, the same list of days as EDIT DAILY
(described in step 1) displays, except that all days
now show the times for the WAKE, LEAVE, RETRN,
and SLEEP programs that you set in the EDIT ALL
DAYS menu.
• If you do not want all days of the week to have the
same program schedule (e.g., weekdays different
than weekends), you can now scroll down and
change the program times for certain days by
positioning the indicator arrow beside the
program time to change and using the + or –
button to increase or decrease the scheduled
program time.
When the program times have been set for all days, press
the Home button to leave the programming menus and
return to the Home Page display. All settings take effect
immediately.
NOTES:
1. Schedule times are in 15-minute intervals.
2. To have the AQ252 ignore a program change
(and therefore keep the previous program's
setpoint temperature), position the cursor
beside the period to be ignored and press the
OK button. The AQ252 will display “--:--”
beside that program and, when operating, will
continue with the previous program's setpoint
until the next program change.
STATISTICS
This sub-menu provides information about system activity
and mix valve cycle counts. See Fig. 3 on page 8 for an
illustration of the statistical data that can be displayed.

TROUBLESHOOTING
Power Disruption
The AQ252’s system and thermostat (zone settings)
parameters are stored in non-volatile memory and are
updated as they change.
When a power disruption or loss of power occurs, the
system configuration is retained in memory.
When power is restored, the AQ252 Control Panel enters
auto-detection mode, reads its previously-stored settings,
and initializes all AQUATROL network components
according to their saved parameters.
POWER DISRUPTION GREATER THAN 4 HOURS
If a power disruption lasts for more than 4 hours, the
AQ252 will have discharged its internal super capacitor,
and the DATE and TIME OF DAY settings will need to be
reset.
Upon restart, the AQ252 displays its clock settings as:
YEAR = 2008, MONTH = JAN, DATE = 1. The message PLS
SET DAY/TIME displays. This displayed message
continues until the DATE and TIME OF DAY are updated.
NOTE: If the power failure parameter is set to Backlight
(USER MENU > PREFERENCES/TIME), the LCD
backlight flashes repeatedly, along with the mes-
sage.
The AQ252 remains permanently in OCCUPIED (or
Comfort) mode until the DAY and TIME OF DAY are
updated.

When a new AQ2000 component is connected on the
AQUATROL network, its settings are communicated to the
AQ252's Boiler Control Module (AQ15200B) within 10
seconds of being connected. If the component is an
AQ1000 thermostat, the setpoints for that zone
thermostat can be modified from the Boiler Control
Module as soon as it is recognized by the Control Module.
When an AQ thermostat is disconnected from the
AQUATROL network, a message displays on the System
Status page of the AQ252 indicating “Lost Zone A-xx”,
