I have a place that is running a 4.2 version of the i-Vu. The programmer insists on setting the high and low setpoint at the same value.
The target setpoint is 70 degrees. In turn he will adjust the Occupied Low Setpoint to 70 and Occupied High Setpoint to 70.

In my sense of logic that keeps the controls constantly adjusting and never settling out.

I would prefer if the target is 70 to set the low at 68 and the high at 72 giving a 4 degree band in the system.

These are clean rooms but we typically don't have a very tight spec we have to maintain.

Is there a good reason to set the high and low at the same number or am I just too old school?
