INSTRUCTIONS:

Fill in the details of the equipment connected to the control module and the zoning module:

• A Low voltage control module wiring
• B Line voltage Boiler pump, DHW pump, and AUX output
• C Low voltage zone thermostats
• D Low voltage zone valves with end switches
• E Review and set DIP switch settings – once DIP switches for the zoning module (AQ25744B) have been set, complete the “Installer Settings” diagram by filling in the circles to indicate the DIP switch position set during installationFile this with other installation records for equipment used on this installation.

A Boiler Control Module – Low Voltage

NOTE: When wiring zone valves with end switches, note the transformer’s VA: If low voltage zone valves with end switches are used for zone control, make sure the selected zone valves do not draw more power (VA) than the 38 VA capacity of the AQ10X38 transformer supplied with the AQ252 Control Panel. This integral transformer has enough power to operate 4 motorized zone valves (such as Honeywell V8043E valves or 4 valves using lowamperage draw, heat motor actuators, such as Honeywell MV100 actuators), plus power the electronics of the AQ252’s Control Module and up to 16 AQ1000 thermostats. If zone valves with highamperage draw, heat  motor actuators are used (such as Taco 500 series zone valves), additional 24 Vac transformer capacity will need to be wired to the  Zoning Module to power the valves. Refer to theInstallation Instructions for AQ255/AQ257 Expansion Zoning Panels (Form No. 69-1981) for recommended wiring of additional low voltage VA capacity to AQ2000 Series Zoning Modules.

CAUTION

Equipment Damage Hazard. 

Can damage internal circuitry of Zoning Module. The ES1 and ES2 terminals of the AQ15740B Zoning Module are powered terminals and must only be connected to a set of dry contacts, such as a zone valve motor’s end switch. If power is applied to these contacts (for example, by running line voltage through the zone valves’ end switches to bring on a circulator feeding those valves), the internal circuitry of the Zoning Module will be damaged, in which case the warranty for this product will be voided.

EQUIPMENT SETTINGS

The Installer Menu is used to establish and modify the system’s equipment and option settings. These include equipment settings for boiler operation, DHW management, zoning, auxiliary input/output operation, and option settings such as pump/valve exercise, and freeze protection.

Use Table 1 to record the equipment settings for this installation.

To record the equipment and option settings: 

• A Press the Home button to return to the Home Page display.
• B Press and hold the OK button for 3 seconds until the message, INSTALLER MODE – ARE YOU SURE?, displays.
• C Select YES, then press and release the OK button to display the Installer Menu.
• D Select the Equipment Setup sub-menu.
• E Record the configured settings in Table 1.
• F Exit Installer mode by selecting the Installer Exit menu option.

Table 1. Installer Menu – Equipment Setup Sub-menu. 

Any entry of two dashes (- -) indicates that the option is disabled or not used.
