Just curious on what goes under the hood, these 2 speed compressors work both in 4 ton then 2 tons by using less pumps? but the motor still spins at the same time right?
when they run at 1st speed does it consume less power or the same but just lower tonnage
also when running a two speed does it kick in on high gear, cool down the home lets say from 85 to 74 then switch to the low speed mode just to maintain the house temp and occasionally kick back the high speed when temps creep up VS a single speed which would just cycle on and off.
Anyhow between the speed capability of the indoor fan coil and the exterior compressor with 2 speeds it looks like a lot of calculations must go on I read that this infinty system measures the outside temp and inside temp to determine I guess comfortlevel etc..
Also anyone know what is the filter size the 05 FE4 model uses(4 ton) I want to stick in a good 3m filter in it (Filtrete Ultra Allergen) this should be fine with the FE4 Handler correct. or will it mess with the system performance?
