Notes:
1.) Stage 2 Electric Heat, Ventilation, Mechanical Dehumidification, and Filter Switch are optional components. Refer to model nomenclature to
verify optional equipment installed in unit.
2.) Use VENT Contacts of Primary Board to activate ventilation using CO2 sensor or other peripheral device. Jumper VENT contacts for constant
ventilation. Option must be used to activate "A" terminal with CRV-F and ERV ventilation options.
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.) Balanced Climate factory jumper is removed from Y2 and Y3 for enhanced moisture removal during 2nd stage of cooling. See unit
installation manual and/or dehumidification supplemental instructions (units with mechanical dehumidification) for additional details regarding
Balanced Climate mode of operation. Jumper can be reinstalled between Y2 and Y3 to disable Balanced Climate operation. (If the unit has a
CRV-F ventilation option, Balanced Climate will not be available. Avoid energizing Y3 if Balanced Climate is desired.)
6.) 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.
7.) MC5300-BC and MC5600-BC controllers have additional alarm board(s) with dry contacts for wired alarms.
