Set Back; Humidifier And Air Flow Direction - Rinnai Energysaver EX38C Manual

Set Back

This function allows a minimum room temperature to be pre-set, between 38ºF
and 78ºF (in 1ºF increments). This temperature should be set below the room
temperature setting. The default setting is 60ºF. Once the Set back function is
selected the appliance will start heating whenever the room temperature falls
below the selected temperature, regardless of timer or manual settings.
Follow these steps to set and operate the Set back feature:
1. Make sure the heater is turned OFF.
2. Press the "Set back" button. The light above the button will come on.
3. Press the up and down buttons to set the minimum temperature.
When the "Set back" indicator is on, frost protection is operating, and will always
prevent the room temperature from falling below the pre-set minimum
temperature (as long as electric power and gas is supplied).
To turn this feature off, press the "Set back" button.
The unit will retain its ON or OFF setting after a power failure. (Set Back feature
is on by factory default.)
