Yes! Any help will be appreciated. Its operating on a rooftop unit with vav controls with a 25 ton system. We just changed over one of the units from a 25 ton carrier and the other a 25 ton trane. Both are now Trane. A/C and economizer only. Heat is in the vav boxes. Thanks for your assistance!
that model number is for the legacy microzone1 generation it can be a water source heat pump,packaged rooftop or a satellite. What is it controlling? i can help with your question
The controller you are describing sounds like the Microzone II. Those terminals are clearly marked. This is an older Microzone unit. Possibly the Microzone I? It has a double terminal strip at the top and the bottom with mixed spade and screw connections.
Pretty straight forward Terminals are IDENTIFIED LEFT HAND SIDE low voltage input / output and ASD bus wiring Communication ASD- ASD + 8 INPUTS ( IN ) 4 OUTPUTS ( AO ) RIGHT HAND SIDE Power wiring and Pilot duty output wiring 8 DIGITAL with NO / NC contacts ( DO ) 24 VOLT power
Anyone have information on the Microzone CVV-90111-0-0-2 Controller? I have no literature for this controller and would like to at least know what terminals are for what.
