Use each of the three buttons as a toggle to a Boolean, each of which activates a NumericSwitch to write either a zero when false, or the appropriate value for the speed you want. Route the three numeric results to a Maximum block to output the highest of the three results to the multistate fan speed point.
Reset the other two Booleans back to false if the multistate value is anything other than the true value for that particular Boolean.
There are enough blocks within kitControl to manage this, if you aren't the sort of Niagara guy to write this as a Program object.

 

Thank you, Sorry what do you mean by the last sentence please? How do you know which one is the latest value chosen? it could be 1 or 3...

 

Try a SetPointFieldEditor from kitPX. This will give you a dropdown on the graphic to the the multi-state for all the values available. This will write the point to the Set Slot of the point. As long as the point does not have a priority override or a something writing to Fallback, it will change the value. This way only one thing to put on the graphic for the point versus multiple ......

The first pic is the graphic option from a browser when selected. The second is the SetPointFieldEditor properties in workbench ......

..............

.................

 

Slick!

 

Thank you, I`ll use that for the time being. As this is for an app like Crestron do, I was trying to create some button.

 

Your welcome, your original post did not state you were attempting to do this with app like Crestron. This information would have been helpful if noted when asking for assistance so we know how to reply properly .....

 

 

Sorry, how could the below works? "Reset the other two Booleans back to false if the multistate value is anything other than the true value for that particular Boolean."

 

Is there a slot we could add to the Enum Writable that would do this?

For example: slot:/FanSpeed/set/High or slot:/FanSpeed/set/Auto

Is this what you want to do?

If so then create a PX page and paste in the following, its too long winded to try to explain how to do this via the forum.
And I find uploading screenshots quite tedious in this forum.
You will need to create an Enumerated point under the config branch with a name of Fan_Speed_Enum.
Then work with it.

Sorry, I omitted that the Enumerated point needs to have facets set up like below.
0=OFF, 1=Speed_1, 2=Speed_2, 3=Speed_3

Obviously, your crestron system might need different values for the fan speeds, but I'm sure you can work that out.
