Hi Marko

With all I/O on the unit what external sensors and actuators can be connected?

AI 0-10?

AO 0-10V?

RTD NTC 10K 25C?

Best regards

Hi Leif,

thank you for your interest in our products.

Regarding sensors and actuators, on the C35 hardver platform we have:

- 3 x 0-10 V outputs (VAV actuator or fan coil, heating and/or coling valve actuators)

- 1 x analog input for RTD1000 temperature sensore (NTC is not supported)

- 1 x 0-10V input for duct CO2 sensor or return signal from VAV actuator

- 1 x binary input for window contact or PIR sensor

- BACnet/MSTP (RS485) communication

Depending on room HVAC application we provide difrent software versions of the C35 hardver:

- C35.FC for fan coil application

- C35.VAV for VAV actuator controls

- C35.FV for fan coil and VAV control (fan coil and valves are controled with analog signals, VAV is controled and configured with BACnet

- C35.FAN for two ECM fan control (kitchen fans or other applications)

All of our BACnet devices could be connected to our web platform with the KOERbox gateway.

Feel free to contact me directly at

I would be happy to show you all capabilites of KOER products.
