LM for controlling AHU units in HVAC system - Admirim Toska - 02.12.2021
Hello
We need to do AHU units control in HVAC system where AHU has:
Water Sensor in pipe to show temp
Pressure sensor in pipe
Anti freeze logic when water is near 0 Grad C, close damper and make pump circulate water.
Air temperature and humidity measured in air pipe
Pressure logic with 2 pressure sensors in air pipe to give alarm filter blocked
CO and VOC sensor in air pipe will be measured by 0-10V and create logic to circulate AIR if to HIGH
And smoke detector in air pipe that close fire damper and switch off fan when detected smoke.
My question is, has any example for controlling UTA according to ASHRAE standard UL 864 Smoke Control ?
thanks

You need certified devices for smoke detection and fire safety. It's not something that LM should be used for.
