Calibration Of Temperature Sensors - Janfire NH Installation And Servicing Instructions

4.8 Calibration of temperature sensors

Calibration may need to be done prior to burner start up. Burner will be in the boiler-room so that all parts in
burner are at room temperature.
Enter service menu row "75 Offset internal" and see temperature there. It will show room temperature (perhaps
o
70 F).
Go then to rows: "71 offset burner bowl" and "72 backburn" and with the aid of offset adjust in temperature so
that it shows the same as "75 Offset internal".
To change: briefly press the "menu" button (temperature numbers flashing) and then adjust using the "+" and "-"
buttons until the temperature is correct.
To save: Press and hold down the "menu" button for three seconds.
NOTE: Temperature on 71 (and 72) does not go to set lower than "75 Offset internal".
"73 Offset Boiler temperature will be adjusted in the same way, But in this case, it must be adjusted to show its
actual temperature.
"75 Offset Outdoor" wil be adjusted to the outdoor temperature.
