Issue
Can a MN-Sx differential setpoint be defined using the WPT Hardware wizard?
Environment
MNL or MNB controller with any MN-Sx sensor
Cause
Project specification requires that all temperature setpoints for a site be fixed and the facility users be allowed to adjust the setpoint with a relative positive or negative offset.
Resolution
In the Workplace Tech Tool use the hardware wizard to configure the setpoint with an initial value of 0.0, one decimal place and no limits.
Configuring the setpoint in this manner allows the setpoint to be changed over the range of -99.0 to +999 without limit.
If limits are required by specification, such as a +/- 3 degree limit, the setpoint value from the sensor would need to be passed through a Limit control object to prevent extreme setpoint offset adjustment.
