GENERAL
These instructions explain the operation, installation and troubleshooting of the MV4000 Series controller.
All internal wiring is complete. Only attach low voltage field wiring to designated terminal strips.
The MV4000 is for use with units with or without economizers, can be configured for use with heat pumps, and has a dehumidification control feature if an optional humidity controller is connected.
Each unit should be sized to handle the total load of the structure if 100% redundancy is required.
