Can somebody explain how the room sensors work if the HVAC system isn’t zoned? How can it send cooler air to one room, or more air to a room? Wouldn’t there need to be something in the ducting or air handler that controls the flow or temperature? I don’t understand how it can be done electronically when everything is coming from one place.
It doesn’t send different temperatures to different rooms in the way you are thinking.
What it is saying it does, is if you have a preferred temperature for where you currently are, then it will cater your temperature preferences toward comfort for where you currently are. So if you prefer 72 degrees as your main comfort temp, then when you are in the family room, the thermostat will turn on the Heat or AC until the family room reaches your preferred temperature. Other places in the house may be warmer or cooler because you don’t have a zoned HVAC or automated venting, etc…but it will try to make you comfortable in the area you are currently occupying. Then instead of having to manually turn the the heater or AC up or down so you are comfortable in the Family Room, the Thermostat will adjust the whole house for you so that you are comfortable in the area you are currently occupying. If you then move to your bedroom to go to bed, then the focus goes toward making you comfortable in there instead (at the potential expense of other areas of the house being warmer or cooler since you aren’t in those places right now, and you just want comfort where you currently are). If there are multiple people in different rooms at the same time, then it can do an average…it will see which rooms have people in them and get the average of those rooms (and the Thermostat room) to average out to your preferred temperature.
It doesn’t balance the ENTIRE house, it just places focus for the preferred temperature in whatever area you are currently occupying. It will always average the sensor temperature with the Thermostat temperature though. It will not base everything solely off a single sensor, but up to 6 sensors plus the thermostat can be used toward this. For those who want the maximum comfort with a single zone HVAC system, this helps to cater the temperature to be comfortable for the room you are currently occupying (other rooms in the house may go up or down more and be less comfortable, but the idea is that you won’t currently be using those rooms, so the longer you stay in a room, the more it will cater the temperature toward where you are at the moment).
For those who want maximum savings instead of maximum comfort, you can just the TStat by itself without sensors and use schedules, and maybe a space heater or space AC for different rooms that have extremes one way or another compared to the rest of the house. Something like that.
In reality, if these sensors are trying to cater to a room that colder or hotter, the end result will be a longer run time to get to said temp desired! Therefore you will be wasting energy. You must have a zoned system for them to be of any savings, and I doubt today’s systems will be compatible with wyze.
Great detail @carverofchoice! Thanks for being so thorough!
