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.

24 VDC Power

For the power supply of some special sensors (e.g. humid­ity) an output voltage of 24 VDC is available at terminals 11 and 12

Supply sensor

For the OTC control the supply temperature is required. The supply water temperature sensor has to be connected to terminal 13 and 14. Sensor type: NTC (20K@25°C)
Figure 24: Wiring Supply water temperature sensor

HCE60/80 boiler feedback

To use the controller in combination with e.g. the HCE60/80 underfloor controller a boiler feedback input is available. The underfloor controller provides a output signal of 0 – 10V based on the heat required from the controlled zones. A room temperature offset is calculated based on a 0-10V input signal. 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.

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.
De-humidifier is switched on.
De-humidifier is switched off.
setpoint and actual supply temperature.
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.

Operation under Fault Conditions

F01: If the outdoor temperature sensor fails the controller will control as normal operation with an assumed outdoor temperature of 10°C.
F02: If the supply temperature sensor fails the heat or cool demand will be disabled and Setpoint supply temperature will be set to 0.
F03: If the room temperature sensor fails the control will continue control as normal operation with an assumed room temperature equal to the room temperature Setpoint.
F04: If OpenTherm communication fails the controller will continue to control as normal operation according to the last received room Setpoint and an assumed room tem­perature equal to the Setpoint.
F05: If the communication interface fails when an outdoor temperature sensor is connected the controller will continue normal operation. Without sensor the controller will con­tinue normal operation with an assumed outdoor tempera­ture of 10°C.
F06: If the relative humidity sensor fails the control will control normal operation as if no relative humidity sensor connected.
F07: If the supply water temperature exceeds the supply high limit supply temperature the pump will be switched off.
