Possibilities of the ITM-A
The possibilities of the ITM-A depend on the hardware configuration. The following hardware configurations are
available:
•
ITM-A without additional analog output.
•
ITM-A with additional analog output.
Set the type of control required using dipswitch 6, 7 and 8.
2.1
ITM-A without analog output - ITM-A
CentralFlow
The ITM-A can be used as an intelligent control module in a CentralFlow system. The ITM-A receives the required
ventilation position from the climate computer. The ITM-A controls the ventilation in a section by measuring the air
flow (DSR feedback signal) and by controlling the valve of the ATM unit.
2.2
ITM-A with analog output - ITM-A
ProFlow/NatuFlow
The ITM-A controls the ventilation in a section by measuring the air flow (DSR feedback signal) and by controlling
the I-fan and the valve of the ATM unit.
The ITM-A can be used as:
1. Energy saving mechanical ventilation system (no possibility to switch to natural ventilation)
2. Energy saving mechanical. & natural ventilation system (possible to switch to natural ventilation)
3. Traditional mechanical ventilation system (no possibility to switch to natural ventilation, fan runs at higher
speed)
4. Mechanical several units in same room (no possibility to switch to natural ventilation)
Remote I/O-module
The climate controller controls the ventilation in the section by directly controlling the outputs of the ITM-A.
When used as a CentralFlow module, the first analog output is not available for direct control.
