FAN CALLS

Number of fan calls currently being serviced. Check the panel

LED if it is necessary to determine exactly which zones are

Equipment Plenum Temperature (PLENUM TEMP)

When the optional plenum air temperature sensor is installed and

enabled, the zone panel will display the Plenum temperature in

the range of 30 - 200˚ F (1 - 93˚C).

Plenum Temperatures outside

this range indicate an equipment error.

See Section 7 Error

Conditions for a further explanation.

NOTES: When no zones are calling, the panel will command

all dampers to open.

• For maximum energy conservation, a purge will occur at the

end of each call.

• No calls will be answered until the purge is complete.

• Dampers will not close if the plenum temperature sensor is not

connected or is not functioning properly.
