TEMPERATURE CONTROLS - INFORMATION
Do not push the ON/OFF button on the
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
If a temperature over 50°C
has been selected on a
controller and priority of
temperature selection is
transferred to another
controller, then back again,
the temperature on the
controller will automatically
drop to 50ºC. If the set
point is 50°C or less it will
not alter. This is a safety
feature.
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
displayed at the controller and the
temperature at the tap.
Temperature priority cannot be switched
to another controller when the water is
flowing through the water heater.
