Control temperature room centrifugal fans & Belimo actuators with 4 temp sensors

Hello,

A friend told me to use your product for my needs.

I have to control the temperature in a 25,000sqft room. I want 4 temperature sensors in the room, average of the 4 sensors will be used to control everything. 1 temperature sensor for the outside just for reference. I need a LCD touchscreen.

Already installed:

  • Inlet centrifugal fan for fresh air from outside
  • Exhaust centrifugal fan with 2 exits for the hot air, 1 to heat the rest of the building, 1 to send air outside of the building, each with 1 damper controlled with Belimo actuator.
  • Automation control panel on the wall to control everything. 120v relays for the fans, 24v relays for the actuators, etc. (currently controlled with regular switches)

I need to be able to:

  • send the hot air in an other room of the builduing OR outside of the building.
  • manually control each fan with a touchscreen button
  • see the temperature of each sensors on the lcd screen

I have some basis in programmation, and I'm electrician.

Can someone help me to build a nice kit, and build the base code?

Thank you!

The rest is more or less just relays. I would guess that you would need a sensor in the other room.
