vance the display to the electricity cost parameter setting.
Electricity cost parameter setting
The DCE Premium has a built-in feature where it calculates the
energy savings of the unit when compared to the average energy
use of a tank-type water heater. In order for this feature to be
accurate, the cost per kWh of electricity must be programmed
into the software.
The secondary display will be flashing to indicate that the value
can be changed by rotating the control knob. Consult your elec-
tricity bill to determine the cost of electricity per kWh.
Pressing the Information button once while at this menu will ad-
vance the display to the display-lock parameter setting.
Display-lock parameter setting
The display can be locked to prevent easy alteration of the tem-
perature setpoint. This menu will flash, indicating that the value
can be changed by rotating the control knob. While “Off” is dis-
played, the lock is not active. The lock is active when the display
reads “On”.
If the display-lock parameter is set to “On” and the user either
holds the Information button for 5 seconds or lets the display time
out for 15 seconds, the display-lock will become active.
With the display-lock active, a lock will appear on the base display,
and no parameters can be changed. In order to disable the lock,
hold the Information button for 12 seconds. The lock will then
disappear and all parameters can be changed again.

parameter setting menu will move the display onto the factory

units can all be reset to their factory settings.

changed by rotating the control knob. When the value is set to
“On”, the reset must be confirmed by holding both Button 1 and
Button 2 simultaneously for 5 seconds.

cumulated savings value can be reset to zero.
