4.1.1 Temperature
The specific
Zone Temperature
(Zone 1, 2, or 3) lists the individual sensor temperature for each zone.
The Ventilation Back-Up Temperature shown will be the average of the enabled sensors (Zone 1, 2, and/or
3). In the Zone Temperature Section, a reading of
“--.-“
indicates the sensor is
disconnected
or in
error
.
Also, if the display is flashing
“OFF”,
it means the sensor is disabled. Therefore, it will not cause the
alarm to sound or be included in the Back-Up System’s average temperature. The Ventilation Back-Up
Temperature displays the average of the enabled Zone Temperature Sensors.
4.1.2 Target
The
Target mode
displays the target temperature used for Zone Alarm Limits and Back-Up Limits. The
Zone Alarm Limits and the Back-Up Limits are referenced to the target much like that of a stage on point
in a controller. Therefore, once initially set, the user will only adjust the target which will automatically
adjust the high and low limits appropriately. The Target temperature can be changed (0.5° increments)
using the Plus (+) or Minus (–) buttons. Example: If the Target Temperature is set to 80.0° F; The High
Zone Limit temperature is set to 92.0° F; The Back-Up High Limit temperature set to 90.0° F; When the
Target is dropped to 70.0° F, the High Zone Limits will change to 82.0° F and the Back-Up High Limit
temperature will change to 80.0° F.
