Tempra Plus display

The Tempra Plus features a primary and secondary display area
allowing for multiple parameters or information to be displayed.
The Tempra Plus is capable of displaying the current flow rate of
the water passing through the water heater, as well as calculating
the accumulated cost savings of having a tankless water heater
compared to a tank-type water heater.
For the name of each display element on the Tempra Plus, consult
section 4.1.2, "Tempra Plus", pg. 4.
5.3.1 Base display
The Tempra Plus base display displays the current setpoint tem-
perature in your preferred temperature unit in the top half of the
display.
The bar below the temperature shows the current fraction of total
capacity that the water heater is running at. As the hot water
demand fluctuates, the power capacity status will change to show
between 0 and 10 segments. The display below shows that the
water heater is operating at 30% of capacity.
The bottom half of the display shows the current flow rate through
the unit in either gallons per minute (gpm) or liters per minute
(l/min).
All other menus will revert back to the base display either after a
15 second period of time without user input, or after a 5 second
hold of the Information button.

savings display.
The accumulated cost savings display will display "I1" in the top
half of the display, and the bottom half of the display will alternate
