Brrrr… Too cold.
Ever had a cold shower in (almost) winter time?

This is because the boiler behaves strangely. Although the it’s full of hot water, cold water is going out.

So, the pile of details gave me: MCU Atmega8, by Atmel; some LM335, temperature sensors by National.com. A pair of CD4051 will allow to use up to 16 analog inputs to the Atmel MCU.

Also, schematics at

. It has some weird details, anyway i will try to master some kind of temperature sensor for the boiler. Just to make sure the will be enough hot water when i’m going to the shower.
Brr…
