Thermostat status (cool mode only)
A snowflake symbol will be lit whenever the thermostat is
calling for cooling. If this is seen to flash, the thermostat output
is delayed for a short period to prevent compressor damage.

A battery symbol will flash in the display when batteries
require replacement. Batteries should be replaced within
15 days, after which the thermostat will turn off the load it is
controlling. When this happens “Of” will be displayed.
IMPORTANT: alkaline batteries must be used
