Functions of the HVAC400 Drive
• Wizards for startup, PID control, pump and fan cascade control, and fire mode to make commissioning easy.
• The Loc Rem button for an easy change between the local and the remote control place. The remote control
place can be I/O or fieldbus. Using a parameter, you can select the remote control place.
• Run interlock input (Damper interlock). Drive does not start before this input is activated.
• A control page to operate and monitor of the most important values quickly.
• Different pre-heat modes to prevent condensation problems.
• A maximum output frequency of 320 Hz.
• A real-time clock and timer functions (an optional battery is necessary). It is possible to program three time
channels and five intervals to get different functions on the drive.
• Two PID controllers are available. You can use them, e.g., to control a valve with the I/O of the HVAC drive.
• A sleep mode function that automatically enables and disables the operation of the drive to save energy.
• A 2-zone PID controller with two different feedback signals: minimum and maximum control.
• Two setpoint sources for the PID control. This is selected using a digital input.
• A function for PID setpoint boost.
• A feedforward function to make the response to the process changes better.
• A process value supervision.
• A pump / fan cascade control is available to control up to five motors.
• A pressure loss compensation to compensate pressure losses in the pipework, e.g., when the sensor is
incorrectly placed near the pump or fan.
• Single input control where the analog signal (0-10V or 4-20 mA) can also be used to start and stop the motor
without additional inputs.

• Resonance sweep wizard to very easily set up skip frequency areas to avoid resonances in the system.
• RTO - Ramp Time Optimizer to automatically adapt to the system to avoid fast accelerations and
decelerations which might harm the water pipes or air ducts.
• Pump soft fill function to prevent overpressures (Liquid hammer) when filling the pipework with liquid.

2.1 PID Mini-Wizard
The application wizard helps you to set the basic parameters that are related to the application.
To start the PID mini-wizard, set the value Activate to parameter P1.18 PID Mini-Wizard in the Quick Setup menu.
The default settings tell you to use the PID controller in the one feedback / one setpoint mode. The default control
place is I/O A, and the default process unit is %.
1 Make selections for Process unit (P3.13.1.4) More than one selection.
If your selection is other than %, you see the next questions. If you select %, the wizard goes directly to question 5.
2 Set a value for Process Unit Min (P3.13.1.5). The range depends on the selection in question 1.
3 Set a value for Process Unit Max (P3.13.1.6). The range depends on the selection in question 1.
4 Set a value for Process Unit Decimals (P3.13.1.7). Range: 0-4.
5 Set a value for Feedback 1 Source Selection (P3.13.3.3). See Table 39. Feedback settings.
If you select an analog input signal, you see the question 6. With other selections, the wizard goes to question 7.
6 Set the signal range of the analog input.
0 = 0-10V / 0…20mA.
1 = 2-10V / 4…20mA.
See Table 19. Analog input settings.
7 Set a value for Error Inversion (P3.13.1.8). 0 = Normal.
1 = Inverted.
8 Set a value for Setpoint Source Selection (P3.13.2.4). See Table 38. Setpoint settings.
If you select an analog input signal, you will see question 9. If you set Keypad Setpoint 1 or Keypad Setpoint 2 for
the value, the wizard will go directly to question 10. With other selections, the wizard will go to question 11.
9 Set the signal range of the analog input.
0 = 0-10V / 0-20mA.
1 = 2-10V / 4-20mA.
See Table 19. Analog input settings.
10 Set a value for Keypad Setpoint 1 (P3.13.2.1) and Keypad
Setpoint 2 (P3.13.2.2) Shows only if you select Keypad Setpoint 1 or Keypad Setpoint 2 in question 8.
11 Using the sleep function. 0 = No.
1 = Yes.
If you enter the value Yes for question 11, you see the next three questions. If you enter the value No, the wizard is
completed.
12 Set a value for Sleep Frequency Limit (P3.13.2.7). Range: 0.00-320.00 Hz.
13 Set a value for Sleep Delay (P3.13.2.8) Range: 0-3000 s.
14 Set a value for Wake-up Level (P3.13.2.9). The range depends on the set process unit.
