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.
