When operating in Frost Protection mode,
the LCD display will show a reading of 5 °C
and also display the Frost Protection
indicator:
When operating in Temporary Override
mode, the LCD display will show the
temporary set point temperature:
To exit from the set point review, press any key except the UP or DOWN keys,
or don’t press any keys for a few seconds – either of these actions will return
the RT500 to Normal mode.
TEMPORARY OVERRIDE
It is possible to temporarily override the current set temperature of the
RT500. There are two ways to do this:
•
While reviewing set point temperature: Pressing the UP or DOWN key
will increase or decrease the set point temperature in 0.5 °C steps.
•
In normal mode press and hold either the up or down key to display the
set point temperature. After a few seconds the RT500 will enter temporary
override mode and will allow increase or decrease of the set point
temperature.
