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.) Ventilation wire between "A" terminals allows for emergency ventilation during a HIGH TEMP 2 alarm. Make sure to set min. position in WH
series unit economizer JADE controller to 10V (fully open) to allow ventilation during a HIGH TEMP 2 alarm.
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.) Units with economizers do not have a Balanced Climate factory installed brass jumper between Y1 and Y2. Please refer to vent manuals for
instruction on how Balanced Climate works with each vent.
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.
