The Ouman S105 is a compact and versatile air conditioning controller controller designed to manage 1-5 stage air conditioners: dampers, cooling, heat recovery, heating and fan controls. It is suitable for both stepless frequency converter-controlled and fixed-speed contactor-controlled AH devices, including AH devices with a battery.
Ouman S105 is an intelligent air handling unit controller that is suitable for all kinds of applications. The controller s diverse and innovative control solutions are as easy to use as the other Ouman controllers that have a reputation for user friendliness. The controller makes it possible to maintain optimal air handling in spite of changing conditions in the room to be ventilated (temperature, CO2 content, humidity, air volume, channel pressure).
Optimal ventilation enhances comfort, safeguards structures and the ventilation device itself, while also conserving energy. Poor air quality leads to fatigue and reduces productivity, while excessively humid air compromises structures. Whether it be in a classroom, auditorium, banquet hall, or workspace, there will always be fresh and highquality air.

0/4 – 20 mA current signal, measurement accuracy 0.1 mA.
Note! If the measurement range of the transmitter measurement is different from 0 – 20 mA, change the Minimum /Maximum setting values of that input (Input configuration -> UIx -> Advanced settings)
– Voltage measurement (inputs 1-16, connectors 11-26):
0 (2) -10V voltage message, meas. accuracy 50 mV.
Note! If the measurement range of the transmitter measurement is different from 0 – 10V, change the Minimum /Maximum setting values of that input (Input configuration -> UIx -> Advanced settings)
