Coal -trol Question

Coal -trol Question

PostBy: pete8116 On: Fri Dec 13, 2013 10:20 pm

This is my first season with the Coal-trol on my new Leisure Line Pioneer rear vent.
I'm noticing that when the stove "ramps up" it seems to over heat the house.
I have the thermostat set at 70 degrees with no set back. The low feed rate is set
at 4 and the high is 36 (recommended by Leisure Line). Should I lower the thermostat
setting? Or is there something else to balance the temperature. The temp had been
74 - 76 degrees. I could see 72 - 73 degrees..
Thanks for the help.

Is there a feed rate adjustment on the stoker mechanism? I know Harman and Keystoker have them. It changes the amount of stroke when the feed is calling.

Where is the thermostat located in relation to the stove. And how is it mounted.

The thermostat is about 15' from the stove on an inside wall. The rooms are all open concept good
air circulation.
Have been wondering if the low feed rate should be increased currently I have it set at 3?

The MIN on a LL stove should be set to 6, maybe lower if you do the MIN/MAX Adjustment procedure (page 12 on most manuals). At a MIN of three your stove might go out when the FR (feed rate is 0).

You may safely ignore 2001Sierra's comment as, even if there is an adjustment (which there is not on a LL), for a Coal-trol equipped stove, the adjustment is set to a specific place and never adjusted again (also in the instruction manual for stove makes with an adjustment).

The feed rate FR on the thermostat is an indicator only and cannot be adjusted by anyone; it's an indication of the percentage size of fire not MIN/MAX and is adjusted automatically in response to the temperature setting and the heat required to maintain the temperature setting (usually the temperature outdoors). When MIN/MAX is set properly, the FR may be interpreted as a percentage of fire size i.e. 50% FR indicates about a half of grate of fire, 0% FR = the minimum size fire and 99% FR = a full grate of fire.

As for swings in temperature, a common problem is that the TS2 thermostat is not mounted on a wall (it will not work on a bookshelf or the arm of a couch or sitting on a coffee table) or the thermostat is not able to register the heat produced by the stove, e.g. the TS is in a different room, in a dead zone of the same room, or even if the TS is upstairs and the furnace/stove is downstairs the hot air produced is not getting to the thermostat in a reasonable time. The heat from the appliance must get to the TS within 10-15 minutes, otherwise it may not be stable. Repositioning the TS may be necessary, or improving air circulation (usually better for your comfort).

I do have the TS mounted on an inside wall.
It is getting good air circulation. The stove in about 15'
away in another room but the area is all open.
After reading your response, I've increased the minimum to 6 like you suggested
and will let you know if it makes a difference.
Thanks
