Too Many Simultaneous Input Signals (Response Code 311)
- This code is set when control unit receives more than one input signal within 8 milliseconds. This is usually the result of a malfunction in a contact or switch, or if wiring has shorted.
- Activate switches to determine which circuit might have caused Code 311 to set. If Code 311 sets again, check wiring and switches in relation to which trouble code should have appeared.
