Both Heater 1 and Heater 2 setting will be highlighted for changes. 1. HEATER 1 SETTING: The OFFSET (1) value is the number of degrees below set point the Heater 1 should turn off. The DIFF (1) + OFFSET (1) values are the number of degrees below the set-point when the Heater 1 is to turn ON. Example above, Set Point = 70F 2. HEATER 2 SETTING: The DIFF (2) + OFFSET (1) + DIFF (1) is the value of degrees below set point where Heater 2 turns ON. Heater 2 turns OFF at the temperature setting DIFF (1) +OFFSET (1) which is the same as when Heater 1 is to turn ON. Example above, Set Point = 70F 18D.

To reset the timer value, press the block displaying the timer value which will launch a new screen to allow user to reset each timer separately or both simultaneously.
