3| Conguring the AHU software
The type of AHU to be controlled is dened by conguring the parameters described later in the manual and
dening 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 congured from the instrument user interface (see “2] User
interface”) or from a PC using the Congurator software “AHU_Interface_vNN.xls” supplied with the algorithm (see
“17] APPENDIX – Use of the Congurator” at the end of this manual).

3.1| Conguration overview
The main steps to adapt the AHU software to your application are as follows
Using the Congurator software “AHU_Interface_vNN.xls” dene the input and output you need.
(See “3.2] Input/Output conguration” 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 dene 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 dene their control probe, setpoint and
changeover conditions. (See “6.1] Damper control sequences”).
Humidity control
Dene the control probe, setpoint and the way dehumidication is performed. (See “11] Humidity control”).
Supply limits
Dene 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
Dene the control type, the control probe and if necessary the PID
control parameters. (See “12] Supply and return fans”).
