I'm not Jerry, but I can help on this one.
Right now the feeder is set at the default which is 4min and 40?max
What do these numbers stand for aside from an indication of rate of feed?
Also is the feed either one or the other, or is it also anything in between, ie a variable feed rate.
They are a percentage of motor on time during a cycle. I don't recall the duration of a cycle off hand, it is something between 100 and 120 seconds believe.
The feed rate is variable. The thermostat will figure out the place between these two settings that keeps the temperature at your setpoint.
With respect to the combustion blower, how many different settings does that have? And the same questions with respect to the convection blowers?
On Leisure Line stoves the combustion motor is always running at 100%. The convection blower is speed controlled, as opposed to time proportioned like the stoker/feeder motor, and varies from roughly 40% to 100%. The speed it runs at is calculated by the thermostat based on the feed rate and a delay, to make sure the air chamber is hot enough so that the air blowing out is not cool.
Also how does the overall house insulation setting impact the above?
The HLF (Heat Loss Factor) setting is new and meant to allow users to make the thermostat more aggressive in dialing up higher feed rates when a setpoint change occurs. The result will be for the stove to get to higher feed rates faster and thus generate the desired heat faster. The default setting is 0 (off) and will behave like earlier models in this mode. There are three settings, 1 through 3, to dial up increasingly aggressive settings. Use of this setting should be limited since it can result in seemingly "eratic" behavior (large temperature overshoots, for example) in many circumstances.
Basically this should only be used if it is taking inordinately long, 2-3 hours for example, for a new setpoint temperature to be reached. Obviously if you're making 10 or 15 degree changes it can take a while for that new temperature to be met and wouldn't necessarily be a candidate for this setting. But if you're seeing those kind of times on 5 degree changes then you could try increasing this value to see if it helps.
If the stove's BTU output is too low for the space you might be able to get a some relief by using this setting too.
However, first steps should be to increase air circulation and increase insulation.
Glad you're happy with your purchase.
