I started testing my amateur product in garege, then folowed some fun.


After all, I have controller for some small HVAC units. Dtermo alows me (depends on what I setup in menu which I made) Serial Communication with WInApp + I can download parameters depends on setups, If I wont I coud have WiFi for some parameters, alarms for shut down device, counter and hours info for relay on board, I can chose which sensor I use (NTC) + Difference settings, I can set delays, etc...


Some pictures:


I made options for 2 kinds of operating : Cooling or Heating with hysteresis and delays.


For now This work great. I use 230AV load to 10A so quite good results. I also use 80m UTP cable for Serial communications (If I wont use).


Happy 2021!
