all the remote controllers are “OFF”, any remote con-
troller can be used to “Lock” all remote controllers.

Lock Funcon
The “Lock” funcon will prevent the buons on the
controller from working a safeguard against small
children or otherwise inappropriate operaon.
 The “Lock” funcon can be used whether the
controller is “ON” or “OFF”.
 When the “Lock” funcon is acve, all other
buons are locked out except for the “LOCK”
buon.
Seng Priority
The “PRIORITY” buon is only used when there is more
than one temperature controller connected to a tank-
less water heater. Only the controller with the
“PRIORITY” icon will have the ability to change the tem-
perature so as to avoid scalding or other injury (please
note that if only 1 controller is installed, the “PRIORITY”
buon will remain lit.)
Press “PRIORITY” buon
-“Priority” icon will be displayed on the controller
allowing the hot water temperature to be
changed.
*When the controller is being powered “ON” the
controller is priorized and the “priority” display
is shown.
*When priority is selected, the set temperature of
the priorized controller becomes the set
temperature of the tankless water heater.
-Regardless of which controller has priority, all
sengs or funcons other than temperature can
be adjusted and used.
