I have an ecobee thermostat that I want to install, but I discovered we have a carrier EIM module in place between our existing thermostat, and our HVAC unit. Here is a wire diagram of the existing setup.
The free hanging blue, yellow, and brown wires are part of the bundle of wires in the wall, but are not connected on either end right now. I engaged with ecobee support, but they wanted to check my HVAC control board. I removed the front panel from my air handler and found all the wires, but it wasn't what they were looking for.
Is it possible that I can just bypass the EIM module by splicing the correct wires together..or do I need something more? Thanks for any help.
