I hope someone can help with a problem i have with some old mitsubushi controllers , the system is a old r22 city multi system two pipe vrf the controllers are connected to a camco controller model no camco
cam110-y i have never seen these before the mitsubushi wired controller is wired into the back of the camco comtroller via a three wire connection.

Of the camco controller there is a remote stat fitted to each area i have 6 systems in total. there is nothing wrong these however all the systems are fed through a on/ off time clock and some system come back on when the timer comes on but not all

im having trouble bringing them all back on . im not sure how they get the signal to auto restart ,

that is the problem some do and some dont i hope someone can help me
