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 or via third party front end
start command (BV software point). When commanded to run the unit will operate in the
following modes:

Occupied Mode

: The unit will maintain



A 54°F (12°C) adj. Cooling setpoint



A 105°F (40 °C) adj. Heating setpoint

Unoccupied Mode (night setback):

The unit will maintain



A 74°F (12°C) adj. Cooling setpoint.



A 85°F (30°C) adj. Heating setpoint.

The values above can be changed by the commissioning agent by using the BACview or via the
BAS.

Auto Changeover Mode

When operating on Changeover mode the unit will automatically change from heat to cool and
vice versa, by using the

Changeover Setpoint

and the

Changeover Deadband

.

These points can be changed by the commissioning agent, the factory defaults are 65°F and
3°F (18°C and 2°C) respectively, the units will enter in cooling or heating mode according to the
following:
