Setting the temperature
Turn setting dial to required temperature.
Frost Protection
To activate frost protection, turn the dial below 10°C. Frost
protection becomes active at 8°C. If the temperature in the
room drops below 8°C then the output will activate.
When frost protection is activated the right LED will turn
orange.
Standby Mode
In cooling mode, the standard frost protection is not available;
instead there is standby mode. When the dial is turned past
10°C the unit enters standby mode and cooling will be inactive
until dial is turned up past 10°C.
