Zone setpoint adjust

The occupant can adjust the heating and cooling setpoints at the zone sensor.

Zone unoccupied override

The occupant can press a button to override the schedule and place the unit in occupied

mode for 30 minutes. Each additional press of the button adds 30 minutes, to a

maximum of 90 minutes. When the override time ends, the schedule controls the unit

again.

Discharge temperature limit control (optional)

The unit monitors the discharge temperature and limits the heating or cooling outputs as

follows:

Mode

Discharge

Temperature

Capacity Limit

Heating

110°F (43°C)

100°F (38°C)

100%

Cooling

48°F (9°C)

100%

40°F (4.5°C)

Freeze protection (optional)

The unit shuts down when it receives a freezestat status.

Smoke detection (optional)

The unit shuts down when it receives a smoke detector status.

Fan

The controller turns on the fan any time the unit is providing cooling. The controller does

not control the fan in heating mode, and the fan output DO3 (G) is off. Fan operation in

heating mode is controlled by third-party controls on the heating equipment. The timed

local override control will override this fan control, forcing the fan to run for the duration of

the override time (optional). To ensure the coils are not active when there is no airflow,

the fan starts one minute before cooling is enabled and runs for five minutes after cooling

turns off.

Fan status (optional)

The Room Controller monitors the fan status. It requires a positive fan status before

enabling any heating or cooling stages.

Cooling

If staged cooling is used, the Room Controller measures the zone temperature and turns

on the first and second stage cooling (if available) as needed to maintain the cooling

setpoint. A 5-minute delay between stages prevents short cycling, and each stage has a 2-

minute minimum on time and a 4-minute minimum off time.
If chilled water is used, the Room Controller measures the zone temperature and

modulates the chilled water valve to maintain the cooling setpoint.
