Place the thermostats on a stable, level,
heat-resistant surface.
Plug one end of the power supply into the back

socket (115/230 Volt +5%/-15% / 50/60 Hz).
Switch on the thermostat by pressing the power
switch on the back.
Note: Do not switch the instrument off and on in rapid
succession. Always wait about 20 seconds before
switching the instrument on again, otherwise you may
damage the electronic and mechanical systems.
The first time the instrument is turned on, the
language selection screen will appear

After initialization the instrument is ready for
operation.
