Heat/Cool Limit Time
Set a time limit for the Auto Heat/Cool Limit. If set to 0, the heat/
cool limit is in affect whenever the channel is in automatic
control.
Range: 0 to 32767 seconds
Heat/Cool Scale Lo
A control output may be linearly scaled by setting this
parameter. Enter the percent of the output range of the
selected Heat/Cool Output Type that should correspond to a
calculated Heat/Cool Output% of 0%.
Range: 0.0% to 100.0%
Heat/Cool Scale Hi
A control output may be linearly scaled by setting this
parameter. Enter the percent of the output range of the
selected Heat/Cool Output Type that should correspond to a
calculated Heat/Cool Output% of 100%.
Range: 0.0% to 100.0%
Sensor Fail Heat% / Cool%
When a failed sensor alarm occurs on a channel under
automatic control, that channel goes to manual control at the
percent power output set here. Enter the default percentage to
which a channel’s output is set if its input sensor fails.
Range: 0.0% to 100.0%
Spread
Enter the offset between heat and cool modes when both heat
and cool outputs for a channel are used. The spread is also the
switching hysteresis for on/off channels with Output Type set to
On/Off. The spread is in the channel’s engineering units.
Range: same as the range of the input type selected. See Table
3.14 on page 130.
