Harman P61a Cellar Dweller pumping up the heat with a remote room probe Success

Hello

Just extending the room probe to another room in roome temp mode can just make the Harman run full bore but I found a way to really make it work!

With outside temps fluctuating from 18 Deg F up to 31 Deg F and snowing back down to 22 Deg this Harman P61a located in the basement has held the livingroom and kitchen upstairs rock steady at 72 Degs F all day since 5:00 AM so far!

The basement temp has flucuated from 74 to 80 deg and the garage is much cooler currently at 46 Degs has made this a difficult task!

The secret is two registers with one in the kitchen and one in the livingroom with an inline booster fan running full bore and the Harmy1 room fan set to medium. The room probe extension wire from the back the Harman runs up to the ceiling and into the cold garage and up into the livingroom wall and then comes out a free port on one of the home theater surround sound sub woofer jacks!. The black room probe is plugged in at this point and brought up to the recommended 5 foot level and looped around the old oil T-Stat to give it a useful purpose again by showing the room temp heated by Harmy1 LOL

One of the registers is located withing 7 feet of the room probe and the other within 8 feet of the room probe and blast out150 Deg F of Harmy1 heat! The feedback from the probe to the control panel with this volume of heat makes the ramping acceptable with the stoves capabilities and therefore very consistant heat upstairs with the stove and pellet mess in the basement!

Now the setting on the panel are 71.25 Deg F running room temp mode with the room fan set to medium at feed rate of 4. The Home Depot inline booster fan in the 6 inch ductwork is running full bore.

Also see my post on cleaning the ESP probe so this room temp mode is very accurate!
Friendly Reminder - Clean your ESP & place your room probe 5 feet above the floor for Optimum heat!

Has anyone else tried this with some success?

Final Analysis
After a few days
The Outside temps varied from 10 Deg to 32 Deg F
The basement temp near the Harman P61a varied from 74 Deg to 82 Deg F
But the Kitchen and Livingroom where the room probe is plugged in and hung at 5 feet above the floor
was 72 and only dropped to 71 Deg F at night. Within 1 Deg per Haram specs!

The bedrooms down the hall remained at a comfortable 68 Deg all day and night!

Unfinished basement? You don't think your wasting alot of BTU's and PELLETS by heating the basement to 74-82 degrees???

Stove in picture looks to be in a very finished area.

I heat my downstairs to 75-80 (stove room) to keep upstairs around 70.

Just how stove heating works.

The basement is finished and insulated so heating the basement does keep the pipes and floor warm.

Exactly, the stove room is always warmer. Having the basement warmer works out nice, it warms the floors and all. Having the livingroom and kitchen 71-72 degrees makes it comfy all the time is perfect!
