Not yet. I wanted to make sure all was well first. I actually just found that I forgot to add lines to re-enable the programs when the time criteria was met. So the home, away and weekend will look like so: If On Mon, Tue, Wed, Thu, Fri From 7:00:00AM To 6:59:00PM (same day) Then Enable Program 'WHF_AWAY' Run Program 'WHF_AWAY' (If) Else Disable Program 'WHF_AWAY'

Ok. Here is the sorted out code fir anyone that wants to play around with whole house fan / Thermostat control. Seems to work well so far. Thanks! I have 3 different programs that run. WHF_Home, WHF_Away and WHF_Weekend. I use 3 triggering programs to determine when they need to be run. These are named HOME, AWAY, WEEKEND. These triggering programs disable 2 of the 3 programs at any point in time when the criteria is met. AWAY: If On Mon, Tue, Wed, Thu, Fri From 7:00:00AM To 6:59:00PM (same day) Then Run Program 'WHF_AWAY' (If) Else Disable Program 'WHF_AWAY' HOME: If On Mon, Tue, Wed, Thu, Fri From 2:00:00PM To 6:59:00AM (next day) Then Run Program 'WHF_HOME' (If) Else Disable Program 'WHF_HOME' Weekend: If On Sat, Sun From 7:00:00AM To 6:59:00AM (next day) Then Run Program 'WHF_WEEKEND' (If) Else Disable Program 'WHF_WEEKEND' WHF_AWAY: If Status 'Outside' <= 70° (Temperature) And Status 'MainThermostat' >= 60° (Temperature) And Status 'MainThermostat' <= 70° (Temperature) Then Set 'FAN1' On Set 'MainThermostat' Mode Off Wait 20 minutes Run Program 'WHF_AWAY' (If) Else Set 'FAN1' Off Set 'MainThermostat' Mode Cool Wait 10 minutes Run Program 'WHF_AWAY' (If) WHF_HOME: If Status 'Outside' < 72° (Temperature) And Status 'MainThermostat' >= 70° (Temperature) Then Set 'FAN1' On Set 'MainThermostat' Mode Off Wait 20 minutes Run Program 'WHF_HOME' (If) Else Set 'FAN1' Off Set 'MainThermostat' Mode Cool Wait 10 minutes Run Program 'WHF_HOME' (If) WHF_WEEKEND: If Status 'Outside' <= 72° (Temperature) And Status 'MainThermostat' >= 70° (Temperature) Then Set 'FAN1' On Set 'MainThermostat' Mode Off Wait 20 minutes Run Program 'WHF_WEEKEND' (If) Else Set 'FAN1' Off Set 'MainThermostat' Mode Cool Wait 10 minutes Run Program 'WHF_WEEKEND' (If)

So far, I will be starting my first inlet very similar to what you described. Unfortunately, my house is all HIP roof. Sooo, I will need to do a roof penetration, or get really creative with freeze blocks. I actually plan on doing both. For the roof penetration, I plan on running one of these: https://www.acwholesalers.com/Fantech/R ... fgodaDAAGw I will have to remove the damper. I will run this http://www.smarthome.com/3086/12-Inch-D ... DNC/p.aspx inline, and on the same scene as the whole house fan. I will be terminating the ducting in my ceiling with one of these: http://www.homedepot.com/p/Master-Flow- ... /100168335 with a standard furnace filter and grill. The filter will just be flipped. Rinse and repeat for multiples.

That did the trick! Now I get to move on to installing actuated and filtered fresh air inlets around the house. Thanks again.

Thank you for this example. I'll play around today and see what i can do with it.

Hello all, First timer here. I just picked up an ISY, insteon wired and wireless thermostat (plus a few on/off modules). I am in the process of implementing a whole house fan strategy that runs the whole house fan in lieu of my AC, if my outside temperature is lower than the inside temp. In short, i have all this working. Here's what i havent figured out yet: When each program runs to query my thermostats, they only run once. So if my thermostat happens to be 75 degrees when the whole house fan kicks, My whole house fan will stay on until the next scheduled time that the program has listed (the end time for that program). I have not figured out how to write a repeat loop for the program, so that it re-runs say, every 10m (re-checks thermostat temps, checks it's run times and adjusts accordingly). I hope that this is an easy fix. The query that I wrote to re-query both thermostats every 10m doesn't seem like the fix :/ Here is a some of the code I am trying: WHF_AWAY: If Status 'Outside' > 45° (Temperature) Or Status 'Outside' < 72° (Temperature) And Status 'MainThermostat' >= 68° (Temperature) And On Mon, Tue, Wed, Thu, Fri From 7:00:00AM To 1:59:00PM (same day) Then Set 'FAN1' On Send Notification to 'Default' content 'FANON' Set 'MainThermostat' Mode Off Else Set 'FAN1' Off Set 'MainThermostat' Mode Cool Send Notification to 'Default' content 'FANOFF' WHF_HOME: If Status 'Outside' > 45° (Temperature) Or Status 'Outside' < 69° (Temperature) And Status 'MainThermostat' >= 68° (Temperature) And On Mon, Tue, Wed, Thu, Fri From 2:00:00PM To 6:59:00AM (next day) Then Set 'FAN1' On Send Notification to 'Default' content 'FANON' Set 'MainThermostat' Mode Off Else Set 'FAN1' Off Set 'MainThermostat' Mode Cool Send Notification to 'Default' content 'FANOFF' WHF_WEEKENDS: If Status 'Outside' > 45° (Temperature) Or Status 'Outside' < 69° (Temperature) And Status 'MainThermostat' > 71° (Temperature) And On Sat From 7:00:00AM To 11:59:00PM (same day) Or On Sun From 12:01:00AM To 6:59:00AM (next day) Then Set 'FAN2' On Send Notification to 'Default' content 'FANON' Set 'MainThermostat' Mode Off Else Set 'FAN2' Off Set 'MainThermostat' Mode Cool Send Notification to 'Default' content 'FANOFF' I'd love some help on a more optimized approach as well. Thanks in advance for any help!
