Refcomp inverter controls
Please help me out with understanding analog outputs from Carell controller:
Y1 is going out to EXV driver
Y2 is the demand signal to Refcomp inverter
Y3 is the demand signal to condenser fan motors inverter
Not sure what is the function of Y1 signal here.
Anyone has any suggestions?
Thank you
