cannot specify "program auto" mode on 2441TH thermostat

[drw]

I have an ISY994i/firmware 4.1.0 with a wired Insteon 2441THR thermostat/rev 1.31.

( I also have a remote 2441THZ thermostat/rev1.2 linked to the ISY).

 

I cannot successfully set mode of operation (to "program auto") from an ISY program. I seem to be able to set mode to "heat".

I am using a command of the form -

 

Set "thermo-main" mode Program Auto

 

After executing the command, the thermostat goes to "heat" mode. Of course, I can manually move it to "program auto" mode by pressing the "mode" button on the thermostat.

I have been able to modify the temperature/setpoint settings successfully.

My 2441TH will react to Auto but the thermostat does not change from its current mode when Program Auto is selected.

I believe that I have found a way around this problem by using scenes.

Set up a scene containing the "thermo main". Configure it the way I want the thermostat to be set- all the settings are available. By turning the scene "on" the thermostat seems to be reliably set into the modes I want.
