ESP 12 worked fine, now disconnects all the time. Server error?

One thing that leaps out at me is this bunch of consecutive Blynk.virtualWrites:

oseloth:

void sendToBlynk()
{
 //send to blynk
 Blynk.virtualWrite(V5, millis() / 1000);
 Blynk.virtualWrite(V6, tempRoom);
 Blynk.virtualWrite(V4, tempBoiler);
 Blynk.virtualWrite(V7, pump);
 Blynk.virtualWrite(V0, tempSet);
 Blynk.virtualWrite(V3, nightMode);
 Blynk.virtualWrite(V2, blockMode);
 Blynk.virtualWrite(V1, manualMode);
 Blynk.virtualWrite(V8, autoMode);
 //Blynk.virtualWrite(V11, tempMobile);
 Blynk.virtualWrite(V12, tempSetDay);
 Blynk.virtualWrite(V13, tempSetNight);
}

Try splitting them into two functions and calling them at slightly different times.

Also, GPIO 16 probably isn’t the best pin to use for your relay, and GPIOs 24, 26 & 9 don’t exist on the ESP (I do realise that you’re not using these at the moment, but just saying).
Have you read this:
