Locking & Limiting
Locking - setting the thermostat at a temperature which
cannot be altered by the user.
Limiting - allowing the user to alter the temperature within
a predened range, which is less than the full range of the
product (i.e. between 18-22°).

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.
