"Priority" function

Temperature cannot be memorized or changed
using the heater's control panel buttons or a
second remote control when hot water is in use
(e.g. during a shower) The "Priority" function
will automatically activate to stop another user
from modifying the temperature when hot
water is in use.
The remote control does not have a default temperature setting
and therefore has no default "Priority" function.The "priority"
will be attributed automatically by the first user who selects or
memorizes (on the remote control or on the heater's control
panel) a temperature for subsequent use (e.g. a shower).
Then, when the hot water is used (e.g. for a shower), the
heater's display and additional remote control displays will
show the symbol " ".
The temperature may only be modified using the same buttons
that set it (depending on whether the control panel or the
remote control was used). The priority device will not have the
symbol " ".
To clear a device that is locked out with the "
(with no hot water running) simply:
▶ press and hold both the "
device for 5 seconds.
The "Priority" function ends:
• 5 minutes after the last use of the hot water (return to basic
set up).
• 2 minutes after selecting/memorizing the temperature if no
hot water is used immediately afterwards
Acquiring "priority"
Any user can acquire "priority" for subsequent use of hot water,
as follows:
▶ Move the heater's main switch to the ON position (I).
▶ Press and hold " " or "
temperature.
▶ Press and hold the "Program" button until the symbol "Pr"
appears on the remote control display.
▶ Use the hot water within two minutes of acquiring
