Version Document A001 Access V4.X Configuration manual Manual Frequency controlled fans can be controlled at a fixed rotational speed. The rotational speed is selected by setting a fixed output signal (0 – 100%). Values for normal and reduced speed can be configured for each fan. Fans that are run with a fixed output signal can also be compensated (see the section above). In this mode, pressure sensors are not needed.
PAGE 12
Version Document A001 Access V4.X Configuration manual transmitter (“Flow supply air”) is placed in the supply air fan cone, providing a measurement of the supply air flow. The supply air fan is controlled using the extract air flow as a setpoint. A scaling factor can be added if the supply air fan does not have the same characteristics as the extract air fan.

Version Document A001 Access V4.X Configuration manual Standby mode If frost protection is activated, the controller will go into ”Standby mode” when the running mode switches to ”Off”. The “Standby mode” will control the heating output to maintain a constant settable temperature at the frost protection sensor “Setpoint Standby mode”. Electric heating Control The heating is controlled using the analogue output and/or signal for start heating or step controller to control 1..4 digital output steps.

Version Document A001 Access V4.X Configuration manual Block step signal if alam   Operation settings: No Yes Data & Settings > Temperature control > Heating (Heating 2) Sequential control Each output step has individually settable on and off values in percent of the control signal. The number of steps is equal to the number of heater/chiller groups. Minimum on and off times can be set, i.e. the minimum time the step has to be inactive or active for a change to occur.

Pump indication A feedback from pump can be used, running indication or alarm indication.
PAGE 22
Version Document A001 Access V4.X Configuration manual DX cooling with exchanger control When running cascade control, the supply air controller setpoint is normally controlled by the room/extract air controller output signal. When DX cooling is activated, the supply air controller setpoint is lowered to five degrees (adjustable) below the setpoint given by the room/extract air controller. This prevents the DX cooling from being activated/deactivated too often.

Therefore, Blocking step 1 will apply to binary steps 1 and 2, Blocking step 2 to binary steps 3 and 4, and Blocking step 3 to binary steps 5, 6 and 7. Blocking of DX cooling on cooling pump alarm Corrigo can be configured to block DX cooling on cooling pump alarm. In- and outputs Override of reduced speed for DX cooling Override to normal quantity of air for DX cooling when the unit runs on reduced quantity of air.

Version Document A001 Access V4.X Configuration manual Mixing dampers (Recirculation and/or Recirculation 2 dampers) Control The analogue output signal (”Recirculation 1” & “Recirculation 2”), control two dampers in separate sequence (“Recirculation 1” & “Recirculation 2”) for gradual mixing of outdoor air and recirculated air. In this mode the output signal decreases with increasing heat demand.

Version Document A001 Access V4.X Configuration manual In applications with varying occupancy the fan speeds or mixing dampers can be controlled by the air quality as measured by a CO2 sensor. With the CO2 function it’s possible to start and stop the fans, compensate the fan speed and in combination with mixing damper let in more outdoor air depending on the CO2 value.
