plate next to room setting. Release the button.
Step 2 Press the M button again. The green bar on the MODE digit of the control panel face plate will
move to indicate storage setting can be adjusted. Core charge level set point is displayed on the

10 = maximum core charge will be maintained
The face plate will automatically return to displaying current room temperature a few seconds after
making an adjustement.

The outdoor sensor will monitor outdoor temperature and provide the information to the heater. The heater will
respond by storing heat in the brick core accordingly. The outdoor temperature at which brick core charging in
the heater is to begin and the outdoor temperature the heater should be at full brick core charge may be adjusted
at the time of installation. The heater comes factory preset to start charging at 60
o F (15.6 o C) and to be at full
brick core charge at 20 o F (-6.67 o C).
