Notes:
1.) Stage 3 Heat Input (Electric Heat), Filter Switch, and Ventilation are optional components. Refer to model nomenclature to verify optional
equipment installed in unit.
2.) Ventilation wire between the unit low voltage terminal "O1" and the "A" terminal on the MC board allows for energization of any factory
installed ventilation or economizer option (Exception:
CRVMWH-* and CHCRV-* vent options not compatible with MC5000). Use VENT
Contacts of Primary Board to activate ventilation using CO2 sensor or other peripheral device. For constant ventilation, jumper VENT contacts.
3.) Optional remote sensors #1 and #2 are temperature resistance 10k type 2. Remote sensor #2 can be used as an outdoor or indoor sensor.
4.) Emergency Off Contacts used in MC series controller to shut down all units. Emergency shutdown factory jumper may be removed to field
install a normally closed relay at each individual unit.
5.) All MC controllers will have a primary control board with connections for units 1 to 3. MC5600 controllers only will have an additional
secondary control board with connections for units 4 to 6.
6.) MC5300-BC and MC5600-BC controllers have additional alarm board(s) with dry contacts for wired alarms.
7.) Compressor Lockout Output will not trigger the alarm on the display of the MC5000 controller (C**H units).
