ThermGuard to help keep bedrooms warm?

I am thinking about installing a ThermGuard to one of my heating zones. This serves the upstairs of my split level house. On this floor there is an open living room/dining room/kitchen, and then three bedrooms and a bath all on the same zone. The pellet stove keeps the open area quite warm, but then the bedrooms get a little cooler than I would like at night (especially my 6 month old's bed room). I am thinking about playing with the thermostat (in the hall way closest to the open area with the stove, furthest away from the son's bed room) and stove settings at night to hopefully find something that will keep his room 62-64 at night, or just get a ThermGuard and find a setting that will run the heat enough to maintain a temperature in the 62-64 degree range in his room.

any advice?

The least expensive way to insure that the little ones bedroom is going to kept at the mentioned temps is to install another thermostat in the bedroom or any bedroom, connected in parallel with the existing thermostat for that zone. Doing this, either one will create a call for heat from that zone, even if the existing thermostat is satisfied.

not sure why I didn't think of that.
