Willxt-Yes,thermostat is simply mechanical thermostat mounted on the wall and contact is conected in series connection with OUT0 - as you can see in schematic. Also OUT1 and OUT2 connected in the same way with another two thermostats...
pat - DS18B20 is digital senzor so there should not be a problem with interferences. I have similar connection on diferent site where senzors and power for relay goes in CAT5 cable and there is no problem.
And also on another site - sensors are conected separerly on 4wire tephone cable and sometimes I saw same problem...
But here when I switch thermostat ON/OFF one time the temperature first time reach 80C and then go back to normal value.
But if I switch termostat few times in short time then temperature reach 127C...
