Note: Specify the “Operation ON sensor” with a number equal to or smaller than that of the “Operation OFF sensor.”
Note: Operation will be carried out as shown in the figure below when “Sensor 1” is set for “Operation ON sensor” and “Sensor
3” is set for “Operation OFF sensor” in [Mode setting] for 3-sensor-type model of units.
Note: Operation will be carried out as shown in the figure below when “Sensor 1” is set for “Operation ON sensor” and “Sensor
6” is set for “Operation OFF sensor” in [Mode setting] for 6-sensor-type model of units.
(3) Set “Outlet HW ” to a temperature between 40.0ºC (104ºF) and 90.0ºC (194ºF).
(4) Touch [OK] to enable the settings.
