Configuring the AHU software
The type of AHU to be controlled is defined by configuring the parameters described later in the manual and
defining the inputs and outputs to be used to control the various elements that make up the AHU.
Both the parameters and the inputs and outputs can be configured from the instrument user interface
(see “2] User
interface”)
or from a PC using the Configurator software “AHU_Interface_vNN.xls” supplied with the algorithm
(see
“17] APPENDIX – Use of the Configurator” at the end of this manual)
.

3.1| Configuration overview
The main steps to adapt the AHU software to your application are as follows
Using the Configurator software “AHU_Interface_vNN.xls” define the input and output you need.
(See “3.2] Input/Output configuration” for the list of all the input and output available)
.
Temperature control.
Assign a temperature control sequence to each of your heating/cooling coils and the actuator type
(See “4] Coils control)
.
Two heating sequences and one cooling sequence are available. For each sequence define the control
probe, the setpoint and the PID control parameters.
(See “6.2] Heat and cool control sequences”)
.
In case of dampers or energy recovery define their control probe, setpoint and
changeover conditions.
(See “6.1] Damper control sequences”)
.
Humidity control
Define the control probe, setpoint and the way dehumidification is performed.
(See “11] Humidity control”)
.
Supply limits
Define the humidity and temperature supply limits which should not be exceeded.
(See “10]
Controlling the supply temperature limits” and “11.4] Controlling the supply humidity limits”)
.
Fans control
Define the control type, the control probe and if necessary the PID
control parameters.
(See “12] Supply and return fans”)
