Having fan stay on after heat / cooling shuts off

[Shawn Aruch]

Hi,

 

I have a Venstar thermostat with the Insteon module and a 99i. What I'd like to do is have a program that when the heat / cool of the thermostat goes off (temp has been reached) the fan then comes back on for 15 minutes to help even the temperature around my house.

 

This will be my first program with the 99i, so I'm not sure where to start.

 

Thanks in advance,

 

Shawn

This will work for heat. You can add another one for cool.

This will wait 1 1/2 mins after heat comes on before fan comes on (don't like blowing cool air).

This will continue to run fan for 15 mins after heat is off.

 

If
       Control 'DEVICES / THERMOSTATS / HU TS (Heat Control)' is switched On
   And Control 'DEVICES / THERMOSTATS / HU TS (Heat Control)' is not switched Off

Then
       Wait  1 minute and 30 seconds
       Set Scene 'LIVING ROOM / LR Ceiling Fan' On

Else
       Wait  15 minutes 
       Set Scene 'LIVING ROOM / LR Ceiling Fan' Off

It isn't a separate fan, but rather the blower on the central air / heat unit. This is what I came up with and seems to work ok.

 

If
       Control '14.21.07 - Heat Control' is switched Off
    Or Control '14.21.07 - Cool Control' is switched Off

Then
       Wait  1 minute 
       Set '14.21.07 - Main' Fan On
       Send Notification to 'Default' content 'Fan On'
       Wait  15 minutes 
       Set '14.21.07 - Main' Fan Auto
       Send Notification to 'Default' content 'Fan Off'

Else
  - No Actions - (To add one, press 'Action')

 

Looks to be working ok for now.

 

Thanks,
