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).

WIRING
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.
The mounting base has two options for wiring:
- Wall or surface wiring (via back)
- wiring from bottom or sides
For safety reasons the wiring of the mains and the low
voltage wires are separated and in different compartments
of the mounting base.
On the left side the low voltage wiring is laid out (inputs,
mainly sensors).
On the right side the mains and the earth wiring is situated
(power and outputs relay contacts) See figure 9.
Wiring holes for wall or surface wiring
For wiring via the back of the mounting base remove the
breakout ports from the wiring holes at the backside of the
base (see Figure 6 indication B).
Wiring holes for bottom or side wiring
For wiring via the bottom or side of the mounting base
cables are required to be used and not separate wires. To
maintain the safety also cable glands are required to be
used when cables enter the controller from the bottom or
side.
Note: Use proper cables and the cable glands to maintain
the IP54 protection.
To install the cable glands remove the breakout ports from
the wiring holes at required location of the base (see
figure 8).
The cable glands will fit a range of cable diameters; therefore check if the proper combination is used.
The connector blocks
The connector blocks (A, B and C) have the same terminals and fit wiring from 0,3 till 1,6 mm². The earth connector
block D fits wiring from 0,3 till 2,7 mm².

CONTROL FUNCTIONS
The AQ3000 controller has various control functions which
can be adjusted with the previous mentioned parameters.
The main control function:
• Heat demand control
• Cool demand control
• Humidity demand control
• Mixing valve control
• Pump control
Control functions which are part of the main control functions:
• Pump and valve seizure protection
• Floor condensation prevention
• Room temperature control
• Maximum supply water control
• Outdoor temperature sensor sharing
Heat demand control
Heat demand is enabled if winter mode is active and outside temperature is below CE3 – 0,5°K
Heat demand is disabled if summer mode or outside temperature above CE3 + 0,5°K
If there is no heat or cool demand the Setpoint supply temperature is set to 0°C.
If heat demand is enabled the Setpoint supply temperature
is calculated by an OTC function (see also fig.21) and is
linked to the following parameters/corrections:
• OTC curve function:
Settings:
- Cd3 = Low limit supply temperature
- Cd4 = High limit supply temperature
- CE3 = Low limit outdoor temperature
- CE4 = High limit outdoor temperature
• Room temperature Setpoint correction:
Settings:
- CAH = Setpoint room temperature
- CE3 = Low limit outdoor temperature
- CCC = Correction coefficient parallel shift
• HCE60/80 boiler feedback Setpoint correction:
Settings:
- If the input signal is above 2,49VDC the offset is 0 K.
- If the input signal is below 2,11VDC the offset is 3 K.
- Between 2,49VDC and 2,11VDC the offset is calculated by linear interpolation.
• Room temperature correction (if sensor present):
Settings:
- CAH = Setpoint room temperature
- CCC = Correction coefficient parallel shift
• If economy mode then economy setback correction
Settings:
- CAH = Setpoint room temperature
- AAH = Economy setback temperature
- CCC = Correction coefficient parallel shift
• Setpoint supply temperature is limited (maximum) to
setting Cd4.
Cool demand control
Cool demand is enabled if summer mode and comfort
mode and outside temperature above CE2 + 0,5°K
Cool demand is disabled if winter mode or economy mode
or outside temperature below CE2 - 0,5°K
If there is no heat or cool demand the Setpoint supply temperature is set to 0°C.
If cool demand is enabled the Setpoint supply temperature
is calculated by an OTC function (see also fig.21) and is
linked to the following parameters/corrections:
• OTC curve function:
Settings:
- Cd1 = Low limit supply temperature
- Cd2 = High limit supply temperature
- CE1 = Low limit outdoor temperature
- CE2 = High limit outdoor temperature
• Room temperature Setpoint correction:
Settings:
- CAE = Setpoint room temperature
- CE2 = High limit outdoor temperature
- CCF = Correction coefficient parallel shift
• Room temperature correction (if sensor present):
Settings:
- CAE = Setpoint room temperature
- CCF = Correction coefficient parallel shift
• Setpoint supply temperature is limited (minimum) to
setting Cd1.
Humidity control
Humidity control is only active when a humidity sensor is
connected and the control is in summer mode.
If humidity sensor and relative humidity above nominal
humidity setting (URN) + hysteresis (dURN) then:
If no humidity sensor or relative humidity below nominal
humidity setting (URN) then:
If there is a Cool demand and no humidity sensor or relative humidity below maximum humidity setting (URM) - 1%
then:
• The pump is switched on
• Cooling is switched on valve is controlled based on
If there is no cool demand or humidity sensor and relative
humidity above maximum humidity setting (URM) + 1%
then:
• The pump is switched off unless seizure protection is
• Cooling is switched off valve is closed.

active
EN1H-0026NL15-R0606 14
Mixing valve control
When heat and cool demand are disabled the valve will be
closed.
When heat or cool demand is enabled the mixing valve
position is calculated based on a PI control algorithm.
Input for the PI control is the actual supply water temperature and the Setpoint supply temperature.
Settings: - bP Proportional band
- tPS Mixing valve runtime
- Eri Integration error coefficient
Pump control
When there is a heat or cool demand the pump will be
switched on.
When there is no heat or cool demand the pump will be
switched off after the pump overrun time (tSP).
When a room temperature sensor is applied and the mixing
valve is closed the pump is switched off after the pump
overrun time (tSP). In this case the pump will be
switched on again when the room temperature (t_A)
is below the room setpoint temperature (CAH) – pump start
offset (PSo) during heating or above the room setpoint
temperature (CAE) + pump start offset (PSo) during cooling.
Pump and valve seizure protection
Every 24 hours, while pump switched off and valve closed,
the pump will run during one minute, followed by opening
and closing the valve.
Floor condensation prevention control
Based on the actual room temperature and the relative
humidity the dew-point is calculated from a standard dewpoint table.
The Setpoint supply temperature during cooling is limited
(minimum) by this value.
The dew-point calculation can be corrected with the dewpoint offset setting (dPo), in cases when the table is not
appropriate to the application.
Maximum supply temperature control
The pump will be switched off when the supply temperature
is above the maximum supply temperature setting (tdM).
The pump will be switched on when the supply temperature
is below the maximum supply temperature setting
(tdM) – 5K.
Outdoor temperature sensor sharing
When multiple controllers are used in the same application
a communication interface is available to use only one
outdoor temperature sensor.
The outdoor sensor information is communicated via the
communication interface to the other controllers.
