Sequence of Operation
Run Conditions:
The unit will run according to a user definable time schedule, dry contact (physical digital input
number 1), manual ON command from BACview control interface, timed local override from
Zone temperature sensor or via third party front end start command (software point). When
commanded to run the unit will operate in the following modes:
Occupied Mode
: The unit will maintain

A 74°F (adj.) Cooling setpoint

A 70°F (adj.) Heating setpoint
Unoccupied Mode (night setback):
The unit will maintain
 A 90°F (adj.) Cooling setpoint.

A 55°F (adj.) Heating setpoint.
The unit will operate and adjust the setpoints according to the heating and cooling limits which
can be changed by the technical agent during the commissioning process if needed. The factory
default limits are the following:
Occupied Limits:
75 °F Heating High
60 °F heating Low
85 °F Cooling High
65 °F Cooling Low
Unoccupied Limits:
70 °F Heating High
50 °F Heating Low
95 °F Cooling High
80 °F Cooling Low
IMPORTANT: It is important not to overlap these limits on their respective modes (occupied and
unoccupied), overlapping may result in unit cycling between heating and cooling.
