Household Zoning

[bad_idea]

Apologies for the slightly off topic question - this is in my home, not the garage. I am fairly ignorant to HVAC control systems. I did however complete an apprenticeship 10 years ago that gave me a basic understanding of HVAC systems. The issue I have is the master suite in our house is about 10 degrees cooler than the living room, where the thermostat is. I would like to install a second thermostat in the bedroom to come on and control the HVAC at night, with the living room thermostat on during the day.

I have a Honeywell T5 thermostat in the living room. The HVAC unit is a Diakin DV59PTCC14AC, installed last April.


Will this work? How will I hook it up? Is there a simpler solution? I know the correct answer is to balance the ducts, and replace the windows in the master suite as the room is packed with low quality windows. Thanks all.

Look into a Honeywell T10 thermostat with remote sensors. You can put up multiple room sensors and program the thermostat to sense temperature from which ever sensor you choose by the time of day. You program in the schedule.

Keep in mind at night you can set the temperature for the bedroom, but the rest of the home will be warmer. If the bedroom runs 10 degrees cooler than the rest of the house, if you set the bedroom for 70F the rest of the house will be 80F.

Really the best choice would be to get more air flow to the bedroom, but I realize this is often impractical in a finished house.

Many years ago, I addressed a similar situation by installing electric baseboard heat in the affected room to supplement the single zone system heating the rest of the house. It was inexpensive and greatly improved comfort. Later, I completely redesigned and replaced our heating system with multiple zones based on heating needs and hours when those rooms were used.

Adding a stat will just raise the whole house why not add quartz or oil filled heater just in ur room. Raise the air flow running the thermostat with fan on see if that improves the air flow thats cooling speed. A simple wiring change in furnace could be made if it works

Kludgy for sure, but I have really long flex duct we put in to help heat our breakfast nook (3 exterior walls, an exterior door and tons of glass) and due to the length of the run got almost no airflow through the vent.

I bought and installed one of these in the flex duct where it hooked into a larger sheet metal duct.

You can control it many ways, but what I did was install this:

In the duct ahead of the booster fan. When the furnace comes on, it raises the temperature of the sensor and it kicks the booster on. When the heat call is over, the duct cools and that controller causes the booster fan to shut down. It does the same thing in the summer only backwards for a/c.

Kludgy for sure...but works great.

I just installed a T10 with 5 sensors in my new house. It does exactly what the OP is wanting.

It comes with four default time periods (Wake, Away, Home, Sleep), but you can add more to suit your lifestlye. For each of those time periods you can either define a room or multiple rooms to matter or put it into occupancy mode where it uses the sensors to focus on occupied rooms.

I set up my Sleep period to be occupancy based because i want it account for guests using the upstairs bedrooms. When there isn't anyone else here, it'll just use the master bedroom temp like the op is wanting. My Wake period is master bedroom only, Away is the base thermostat. Home is occupancy. So far so good.

Isn’t the recommendation to run bedrooms cooler than the rest of the house?
