Balanced zone controller

Posted by tomasz in HVAC Zoning, Home Improvements, Life

One of the nicest features of our new HVAC zone system is module called balanced controller. Basically it’s an algorithm calculating heat demand in every zone and opening and closing registers accordingly.

Here you can see that one of the zones (middle one) was fully open while remaining two were just barely moved, Then when this zone was satisfied in it’s heat demand it was closed and the first one was fully open to direct all hot heat into this zone to shorten furnace running time to the minimum.

I don’t have any statistic data to prove my theory yet but it seems to me that such behavior shortens greatly overall running time and simply saves us money.

Today I saw funny thing on the washing machine description flyer:

20 washing modes (e.g. mini 30, hand washing, baby, mix 40, wool, cotton).

Since when do we wash children in washing machines?

Chart freak

Posted by tomasz in Bike, Life

Short two loops done this morning to warm things up before so boring day at the office. Each of them covered 2.5 miles of hilly gravel road and 1.7 mile of paved one treated mostly as recovery part :-). Main focus was placed on keeping cadence on the steady level around 80 rpm. As you can see average cadence of 81 pretty much nailed it down.
