We are having a difference of opinion on the intended use of the "stage" tag.

One party believes the "stage" tag should be used as:

cooling stage1 cmd

cooling stage2 cmd

cooling stage3 cmd

where the cooling "stage" is represented by values of "0" or "1"

The other party believes the "stage" tag should be used as:

cooling stage cmd

where the cooling "stage" is represented by 0, 1, 2 or 3

Could someone please clarify this for us?

When you say stage are these stages dynamic? Meaning the stage could change?

Let's take an Example:

I have 4 Chillers, CH1, CH2, CH3, and CH4.

Are you talking about having the stage tag determine the run order of the Chiller?

If so when would you have it set to stage=0?

I think stage 1,2,3 etc should be used, and you shouldn't use 0.

The current definition is that stage should have a number value starting at one (not zero).

cool stage:1 cmd
cool stage:2 cmd
