snowtech Posted September 4, 2014 Share Posted September 4, 2014 Hi Guys, I just installed a Venstar Thermostat and I don't know if Im doing something wrong or this device is missing an important feature. I need to trigger things as the fan goes ON. My Fan shows its Off all the time, even when the system is working. The fan is set to Auto because I don't want it running 24/7. I tried to reinstall it, making sure everything was OFF when linking. Am I missing something here ? Thank you all ! Link to comment
paulbates Posted September 4, 2014 Share Posted September 4, 2014 Hi "Fan On" is set when someone opens the door of the thermostat and manually presses the fan On button (or you send "Fan On" from the ISY). However, it does not show "Fan On" if your HVAC unit turns on the fan in response to heating or cooling. The HVAC unit physically turns the fan on locally in the unit itself. There might be other ways to get the results you are looking for. Could you provide more information on what you want to do, eg measure run time? Link to comment

I have a booster fan inside my air duct for my master bedroom. I want every time the fan for the HVAC goes ON to turn my booster ON as well. Thats the solution Im using right now: If Status 'Thermostat - Cool Ctl' is On Then Set 'Booster Fan' Fast On Else Set 'Booster Fan' Fast Off Its working ... Thanks a lot ! Thiago Link to comment
paulbates Posted October 10, 2014 Share Posted October 10, 2014 Yep, you got it. I have the same duct booster situation. I use my thermostats' mode changes and outside temperature to turn that on. Link to comment
stusviews Posted October 10, 2014 Share Posted October 10, 2014 You may want to add an "Or" when heat is called for. Link to comment
