Hi Guys,

 

I wrote the following program with the hopes of turning on the fan for different intervals throughout the day

 

If

        From     5:00:00AM

        To       8:59:59PM (same day)

 

Then

        Set 'Thermostat - Main' Fan On

        Wait  15 minutes 

        Set 'Thermostat - Main' Fan Auto

        Wait  15 minutes 

        Set 'Thermostat - Main' Fan On

        Wait  15 minutes 

        Set 'Thermostat - Main' Fan Auto

        Wait  15 minutes 

        Repeat 15 times

 

Else

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

 

It seems that the program will correctly run the first time (between 5 Am to 5:45 Am) but then does not repeat for the rest of the time.

 

Can you guys set me straight here or offer me some advice on how to make sure this program will run every hour throughout the day (ie. 5AM, 6AM, 7AM, etc

 

Am I missing something here?

 

Thanks

Hi Calberrt

 

It looks like you want to run the fan for 15 minutes every half hour. Give this a try

If

        From     5:00:00AM

        To       8:59:59PM (same day)

Then

        Repeat every 30 minutes

           Set 'Thermostat - Main' Fan On

           Wait  15 minutes 

           Set 'Thermostat - Main' Fan Auto

Else

           Set 'Thermostat - Main' Fan Auto

The repeat statement operates on the indented statements below it. As long as the If statements are true, the repeat statement will keep restarting every 30 minutes and run the 3 statements. The else makes sure that the fan really goes off when the program completes

 

If you want it to run the fan for 15 minutes every hour, change the '30 minutes' to '1 hour'

Info only: If the HVAC is heating or cooling, setting the fan to Auto will not turn the fan off.

Thanks guys...this worked like a charm.  things are running quite smoothly with the recently purchased 2441th.  Sorted out the fan program (running for 6 hours without a problem) and temps now worked out.  Look forward to may other things to do with the ISY

Glad its working for you
