calberrt Posted December 29, 2014 Posted December 29, 2014 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 calberrt
paulbates Posted December 29, 2014 Posted December 29, 2014 (edited) 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' Paul Edited December 29, 2014 by paulbates
stusviews Posted December 29, 2014 Posted December 29, 2014 Info only: If the HVAC is heating or cooling, setting the fan to Auto will not turn the fan off.
calberrt Posted December 29, 2014 Author Posted December 29, 2014 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
