Nice Nest Thermostat Wiring Diagram Heat Only Collections - The characteristic to show on the fan each 15 minutes is an intermittent fan function that recirculates the air throughout slight temp intervals when your warmness or a/c won’t run that tons…if the fan isn’t strolling, it may’t clear out the air… so intermittent fan reasons the fan to turn on 3 to four instances an hour so it at the least filters the air for you when it’s not calling for a/c or warmth. How it works is whilst it's miles happy from a heat or a/c call, a countdown timer initiates and if it’s allowed to go to zero, it turns on the fan for approximately five mins and shuts backpedal. This allows your device to filter the air periodically when it usually might be off, as opposed to walking all of the time in case you put the fan switch to “on”.
As some distance as i’m concerned, these alternatives fall a ways brief of what i anticipate from a “smart” thermostat. Consequently, i embarked on a quest to parent out a manner to trick the nest thermostat into wondering my heating system’s ventilation fan is an air conditioner.
Of path, you could’t lower your house’s average temperature the use of air move, but in a two-tale residence a gain may be gained by means of circulating the cooler downstairs air thru the higher stage. Plus, shifting air makes you sense cooler, even when it’s only a fan blowing it around inside the room you’re in.
My first step turned into to investigate the capabilities of the nest thermostat’s input and output terminals, in addition to the control alerts implemented via usual 24vac-managed heating structures. The instance below, tailored from the nest pro installer manual, suggests how the nest tool is usually mounted to heating-simplest and heating-plus-cooling systems. Regular connection of nest thermostat to heating-only and heating cooling hvacs (click on photograph to make bigger) via a few research and experimentation, i hit upon a wiring trick that causes my nest to control my heating gadget’s fan the identical way it controls an air conditioner’s compressor, the usage of its cool mode for time and temperature set-factors. Observe that because this hack connects both the y1 and g terminals to the fan manage (normally green) wire, you can’t use this hack in conjunction with an real air conditioner. Alternatively, if nest have been to enforce a committed fan-best mode in firmware, the jumper cord might not be wished and a fan-most effective mode could now not avert the nest’s trendy, a/c-connected cool mode.
