5.2 Tempra Trend display
The Tempra Trend display features a temperature and power ca-
pacity display. The display is backlit and will illuminate whenever
user input is detected. The backlight will time out and deactivate
if no user input has been detected for 15 seconds.
For the name of each display element on the Tempra Trend, consult
section 4.1.1, “Tempra Trend”, pg. 4.
5.2.1 Base display
The base display shows the current temperature setpoint in your
preferred temperature unit. The bar below the temperature shows
the current operating capacity. As the hot water demand fluctu-
ates, the power capacity status will change to show between 0
and 10 segments. The display below shows that the water heater
is operating at 40% of capacity.
All other menu displays 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 T
max
button.
Changing the setpoint temperature
The setpoint temperature can be set between 68 °F (20 °C) and
140 °F (60 °C).
The setpoint can be increased by turning the control knob clock-
wise, and decreased by turning it counter-clockwise. The water
heater can be deactivated while still powered by turning the con-
trol knob counter-clockwise, past the 68 °F (20 °C) setting.
5.2.2 Parameters menu
While at the base display, holding the T
max
button for 5 seconds
will advance the display to the first parameter menu.
T
max
parameter setting
The first parameter menu sets the value for T
max
. The value of
T
max
acts as a high temperature limiter. If the T
max
value is set, the
setpoint of the water heater cannot be set above the T
max
value.
This feature is useful in scenarios where scalding from hot water
is a real possibility.
At the T
max
setting menu, the display will flash, indicating that the
value can be changed by rotating the control knob. The T
max
value
can be increased by turning the control knob clockwise, and de-
creased by turning it counter-clockwise. The T
max
value can be de-
activated by turning the control knob counter-clockwise, past the
68 °F (20 °C) setting. The display will read "Off" if T
max
is inactive.
If the T
max
symbol is visible at the base display, then the T
max
func-
tion is active and is limiting the maximum allowable temperature
to the preset level.
