I have seen several posts that have asked about turning the fan off for heating and cooling as the HVAC system does this automatically.
Here is one approach that might work.
- Have an option to have the fan turn on with heat and one for cooling.
- As part of these have a schedule for each one that will allow the fan to be cycled on and off based on this schedule.
- Delay start option that a user can change for radiant heat that has a fan requirement. This is need as you need to have the coils be at least 75% or greater heated before turning on the fan.
I agree. Also for non automatic HVAC it may be wise to keep the fan running for x minutes after heating or cooling element stopped
You are correct, I just forgot to add that.
While we are on the topic, there’s the feature of intermittant fan use. It would turn on the fan for
n minutes, and off for
m minutes. For example, on for 10 minutes, off for 50. Or 10/20 or whatever.
The goal of this feature is to improve indoor air quality. That could be removing pet fur, dust, disease (for HVAC systems that have a UV light to kill living things), volitile organic compounds (for HVAC systems that have filters that can handle VOCs), and so forth.
I expect these fan features will get queued up after OH3 and having a schedule.
