Master controller after transferring priority
of temperature selection to a Secondary
controller as the system will shut down.
Do Not Turn OFF
the Master
Controller
Temperature priority can not be switched
to another controller when the water is
flowing through the water heater.
Depending on the weather conditions
and the length of the pipe between the
heater and the tap in use, there may be a
variation between the temperature dis-
played at the controller and the tempera-
ture at the tap.
Do not clean the control with
solvents or detergents. Use only a soft
damp cloth.
If a temperature 50
0
C or higher has been selected on a controller and priority of tem-
perature selection is transferred to another controller, then back again, the temperature
on the controller will automatically drop to 50(or 42)ºC. If the set point is 50(or 42)
0
C or
less it will not alter. This is a safety feature.
