Trane CTI

[joken]

Would it work to have multiple thermostats paralelled to a CTI. I need to have any one of three stats make a cooling call to a Precedent RTU. I know it sounds goofy but it's a bad fix for a bad design. Thanks, Ken

Why not use 1 Thermostat with 2 remote sensors and set up for temperature averaging ?

Doctors procedure rooms 100% OSA , heat recovery, duct heaters. Two rooms face south and one west. Not good. Ken

Should work as long as the rtu is cooling only. Sounds like a hardwired VVT system without dampers. If it was me, I'll keep a master t'stat to control the fan and install a relay off fan control enable cooling output from other t'stats.

The bigger question is how do you get a precedent to run on 100% OA, even with an ERV you will have a hard time with the latent load. You have a thin DX coil. I would use a leaving air controller with room reset and a duct heater for each zone as reheat.
