Perf data Performance data menu

What the display is showing

Read-only menu on the boiler controller with live readings used while diagnosing. Item numbers named in the guide: 03 supply thermistor, 04 return thermistor, 06 exhaust thermistor, 08 inlet water thermistor, 10 heat exchanger thermistor, 13 water flow control valve position (0 = mid, 1 = open), 15 three-way valve position (0 = mid, 1 = DHW, 2 = CH), 30 indirect tank thermistor, 31 outdoor sensor. A reading of -40°F means the sensor is unplugged or has a bad connection. The guide cites menu 7 both for the DHW outgoing temperature and for recirculation flow, so check the installation manual or tech sheet for the exact item list. The guide does not describe how to open the menu; use the installation manual or tech sheet.
