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). 3 EN1H-0026NL15-R0606

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. cope of delivery Outdoor sensor Heater Chiller De-humidfier Room stat/sensor Humidity sensor upply sensor Pump Mixing valve Figure 3: cope of delivery The W6560C1005 Controller consisting of: - front cover - mounting base Dimensions Figure 2: Layout of the AQ3000 controller application Application items Heater - hot water generator Chiller - cold water generator Pump - distribution pump for underfloor heating loop Mixing valve - controls proper water temperature De-humidifier - lowers humidity to avoid condensation uppy sensor - supply water temperature Outdoor sensor - outdoor temperature Roomstat/sensor - room compensation Humidity sensor - humidity of air in room Figure 4: AQ3000 dimensions, including front cover (all measures in mm) EN1H-0026NL15-R0606 4

5 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): Unscrew the two screws of the front cover (1) Pull the front cover off the mounting base (2). To place the front cover on the mounting base: Properly line up the mounting base and front cover. Push the front cover and mounting base firmly together. ecure 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). Figure 7: Mounting and removing of the controller on a DIN-rail 5 EN1H-0026NL15-R0606

6 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 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. 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) ee 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. Figure 9: The positioning of connector blocks 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. Figure 8: Wiring holes with cable glands EN1H-0026NL15-R0606 6

14 CONTROL FUNCTION 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 etpoint supply temperature is set to 0 C. If heat demand is enabled the etpoint supply temperature is calculated by an OTC function (see also fig.21) and is linked to the following parameters/corrections: OTC curve function: ettings: - Cd3 = Low limit supply temperature - Cd4 = High limit supply temperature - CE3 = Low limit outdoor temperature - CE4 = High limit outdoor temperature Room temperature etpoint correction: ettings: - CAH = etpoint room temperature - CE3 = Low limit outdoor temperature - CCC = Correction coefficient parallel shift HCE60/80 boiler feedback etpoint correction: ettings: - 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): ettings: - CAH = etpoint room temperature - CCC = Correction coefficient parallel shift If economy mode then economy setback correction ettings: - CAH = etpoint room temperature - AAH = Economy setback temperature - CCC = Correction coefficient parallel shift 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 etpoint supply temperature is set to 0 C. If cool demand is enabled the etpoint supply temperature is calculated by an OTC function (see also fig.21) and is linked to the following parameters/corrections: OTC curve function: ettings: - Cd1 = Low limit supply temperature - Cd2 = High limit supply temperature - CE1 = Low limit outdoor temperature - CE2 = High limit outdoor temperature Room temperature etpoint correction: ettings: - CAE = etpoint room temperature - CE2 = High limit outdoor temperature - CCF = Correction coefficient parallel shift Room temperature correction (if sensor present): ettings: - CAE = etpoint room temperature - CCF = Correction coefficient parallel shift etpoint 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: De-humidifier is switched on. If no humidity sensor or relative humidity below nominal humidity setting (URN) then: De-humidifier is switched off. 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 setpoint and actual supply temperature. 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 active Cooling is switched off valve is closed. etpoint supply temperature is limited (maximum) to setting Cd4. EN1H-0026NL15-R

15 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 etpoint supply temperature. ettings: - bp Proportional band - tp 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 (tp). When a room temperature sensor is applied and the mixing valve is closed the pump is switched off after the pump overrun time (tp). 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 (Po) during heating or above the room setpoint temperature (CAE) + pump start offset (Po) 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 etpoint 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. FAULT HANDLING Fault Codes & Diagnostics Fault codes are displayed in the default display. Fault Code F01 F02 F03 F04 F05 F06 F07 Description No outdoor temperature sensor or sensor failure No supply temperature sensor or sensor failure Room temperature sensor failure OpenTherm communication failure Communication interface failure Relative humidity sensor failure High temperature limit active 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 etpoint 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 etpoint. F04: If OpenTherm communication fails the controller will continue to control as normal operation according to the last received room etpoint and an assumed room temperature equal to the etpoint. 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. 15 EN1H-0026NL15-R0606
