Convection fan min.

Convection fan min.

PostBy: plumb-r On: Wed Dec 02, 2009 10:58 pm

I would like to get my convection fan to blow harder than the ts2 v3 is allowing it to. I think that I need to adjust the CFM setting to up the fan speed. Is this correct? I think I saw in another thread that factory default setting on CFM is 30. If I up this setting to say 40 the fan will blow harder? Any help is appreciated. :)

All readings on the Coal-trol are percentages of your max and min settings . CFT is a threshold. So actually lowering the CFT value will have the fan come on sooner a higher setting will have it come on later. The MANFAN function is used to established a temporary fan setting. They "Coal-Trol" are trying to maintain a warm air wash over stove so you do not move air over a cool stove.

Thanks 2001sierra, I have allready adjusted my cft to 6 to get fan to come on sooner. Now I'm trying to get it to blow harder. I'm just trying to conferm that CFM will do this and that I'm looking for a higher number to do that. Thanks! :)

I don;t think the actual CFM will change, the CFT will just make it come on faster at a lower feed rate. The actual CFM will vary with feed rate, so unless you crank up the thermostat to make the feed rate rise, therefore, the CFM will increase.

I know what you are saying, I normally just put mine on MANUAL (FSM) and set the blowers about 50% to help move the air faster for a while, if the Feed rate goes above the limit the fans are set at, it will automatically go back to normal. Then I put it back after 20-30 mins and it does raise the temp 1-2 degrees in the living room faster.

Maybe Paul @ Coaltrol can shed some light if there is an advanced setting to change the Fan Speed based on Feed rate or something?

Plumb-r, yes, adjusting CFM up will increase the speed of the fan. This increase will be most apparent at the low end of its running range vis-a-vis the FR. For example, if CFT is 6, then when FR is 6 the fan runs at its minimum speed as set by CFM and this will be the FR level at which the most fan speed increase will occur. If you're wanting to increase the speed of the fan when FR is 50%, the CFM change will affect it, but it will be must less pronounced compared to the change at FR of 6. Since we do not have an option for adjusting the FR at which maximum fan speed is applied, the CFM change is the best you'll be able to do.

I don't know your fan specs but you should look at them so you don't over work it.
