GENERAL

Safety instructions

• When performing any work (installation, mounting, start­up), all instructions given by the manufacturer and in
particular the safety instructions provided in the Installa­tion instructions must be followed.

• The AQ3000 controller may only be installed and

mounted by authorised and trained personnel.

• If the unit is modified in any way, except by the manu­facturer, all warranties concerning operation and safety
are invalidated.

• Make sure that local standards and regulations are
respected at all times.

• Use only accessory equipment that comes from or has
been approved by Honeywell.

• Before the controller is dismantled, disconnect the main
power supply.

CAUTION

Disconnect the mains power supply before you start

to install the AQ3000 controller. Do not reconnect
the power supply until you have completed installa­tion.

Product description

Figure 1: AQ3000 controller

The AQ3000 controller W6560C1005 is a configurable

heating/cooling outdoor temperature compensated under­floor controller.
Via a simple menu structure and the 5 buttons the control­ler can easily be configured according to the application
specific settings.
The controller has a number of control forms, which are
depending on the configuration and the connected sensors.
The standard heating control form is the OTC, where the
supply water temperature is controlled according to a heat­ing curve with the outdoor temperature. The heat and cool
requests (relay contacts) and the positioning of the mixing
valve (open and close relay contacts) are both controlled.
When a room sensor or thermostat is installed room com­pensation is added to the OTC control function.
During cooling control the AQ3000 controller has the option
to connect also a humidity sensor and to control a de­humidifier (relay contact).

System overview

The AQ3000 controller is designed for controlling individ-

ual underfloor systems, which require:

• Outdoor temperature compensation

• Heating and Cooling control.

• Mixing valve control

• Pump control

• Room compensation

• Humidity control

The functionality of the controller depends on the installed

sensors and the configuration. The AQ3000 controller is

designed in a way that it can be configured and upgraded
to meet individual application needs.

MOUNTING

The AQ3000 controller is designed to be mounted directly

on the wall or on a DIN-rail

NOTE: Improper wall mounting lowers the IP protection.

Placing or removing of the front cover

To remove the front cover from the mounting base (see
figure 5):

f Unscrew the two screws of the front cover (1)
f Pull the front cover off the mounting base (2).

To place the front cover on the mounting base:

f Properly line up the mounting base and front cover.
f Push the front cover and mounting base firmly together.
f Secure the front cover by screwing the two screws.

NOTE: Make sure that all connector pins are lined up and

fall into the right connector before forcing the front
panel and mounting base together..

Figure 6: Drawing off the mounting base

Mounting on DIN-rail

The controller can easily be clicked on to a DIN-rail via the
special click fingers on both sides of the mounting base.

Hold the controller under an angle and hook on to the top
of the DIN-rail.

Push the controller straight and against the DIN-rail.
The click fingers will snap on the bottom of the DIN-rail.
For removal bend the click fingers (1) and pull the controller

of the DIN-rail (2).

Figure 5: Mounting the front cover on the mounting

base

Wall mounting

Four 4.0-mm holes for installation are located on the
AQ3000 mounting base for wall mounting.
Before wall mounting break-out the plastic in the pre­punched drill holes (A).

For wiring from the back break-out the plastic ports of the
wiring holes (B).

Use screws (max. diameter 4 mm) and wall plugs suitable
for the wall material (not included in the delivery).
