Re: OCC and UNOCC mode and setpoint (DO NOT EDIT THIS:56289)

Ronnie,

All,

I’ve tried my best to figure out what setpoint is controlling the Daikin unit via the IntesisBox. It seems that I’m getting no help from IntesisBox factory support. Why? It take days between answers. I still have no answer from the last email.

If anyone is listening, I thought the problem may be that the iTouch manager set to “Master.” We set it to “Slave” yesterday. No change. This morning, I logged into the system and it still was doing its own thing again. The point that is in control is most definitely “Setpoint_command.” That is the setpoint that the unit is maintaining. Every time I log in – no matter occupied or unoccupied – it is maintaining the Setpoint_command value. Why?

Furthermore, yesterday, I saw the Setpoint_status change to the unoccupied value. This was the first time I ever saw it do that – probably due to making the iTouch a “Slave” – is my estimation. That lasted 30 minutes and then the Setpoint_status reverted back to the Setpoint_command value? Why???

How do I take the Setpoint_command out of service where the unit will operate at the normal occupied and unoccupied setpoints? I tried taking it “Out of Service” but I received an error when trying to write to that.

Josep,

I verified all the UnoccupiedDeadandAction points were set to OFF. Below, I have a pic of all the points pulled in from the IntesisBox.

Here are the fan status’s at the same time I took the pic of the points from the Intesisbox. 3 of the units the fans were running, yet the zone temperature is above the unoccupied heating setpoint.

Hello Ronnie,

There is the object UnoccupiedDeadbandAction, to control if you want the unit to switch off by itself when room temp within bounds.

Now, what I don’t make sense here is of the setpoint going to that particular value, which is not UCS or UHS. It means that this value comes from either any change on the unit from local panel, or from direct control of cmd setpoint in our device - this object always overrides any automated setpoint that would come from occupancy/unoccupancy functionality.

Ken,

I have not heard a response to the last question posed about the IntesisBox not controlling to unoccupied setpoints.

Hello Ken,

Can you forward me the email chain?

Hi Ken,

Below is the most recent email from Ronnie concerning the issue:

Matt,

It appears that I’ve figured out the problem with the setpoint status and the setpoint command. I changed the write policy to the setpoint command so it doesn’t write all the time – only when it changes via the wall stat or the JACE. That worked. By the way, neither Ken Smyers or the factory ever got back with me on this issue.

I have an additional question that might be Daikin related. Why does the fan run all the time – even in unoccupied? According to Intesysbox when you set the “UnoccupiedDeadbandAction” to OFF (shown in the points list below), the unit only should be active or ON when the zone temperature falls below the heat and above the cooling unoccupied setpoints. Notice in the graphic below that shows the unit fan is ON and the zone temperature between the unocc setpoints, yet the “On/Off Status” is ON and the fan status is ON.

Thanks for the help.

As for the Fan status, is that on status set in the AC? Also from what it looks like the value is high in the pics you supplied. Have you tried changing the states?
