Function
The desired setpoint temperature is set with the
two adjusting buttons "+" and "-". If the current
temperature deviates from the set setpoint temper-
ature, a relay is switched. The switching status of
the relay is indicated by an LED in the unit (LED on
= relay switched on).
If the relay is switched, the operating hours are
also counted.
Adjustment menu
Press the adjusting buttons "+" and "-" simultane-
ously (at least 3 seconds) for the password
request.
By entering the password "179", the operating
hours counter is set to 0.
Entering the password "289" calls up the adjust-
ment menu.
The adjustment menu scrolls linearly. The dis-
played value is changed with an adjusting button
"+" or "-". Pressing "+" and "-" at the same time
confirms the selection and the next setting value is
called up.
