The screed heating function, when active, is signalled on the main
screen by the scrolling message at the bottom of the SCREED HEATING
FUNCTION IN PROGRESS - OUTLET TEMPERATURE, while on the
electronic board the red and green LEDs flash alternately with a frequency
of 1 sec ON - 1 sec OFF. The "screed heating" function lasts 168 hours (7
days) during which, in the zones configured as low temperature, a heating
request is simulated with an initial zone outlet of 20°C, then increased in
line with the table on the side. Accessing the INFO menu from the main
page of the REC10 it is possible to display the TIME FUNC SCREED
HEATING value regarding the number of hours since the start of the
function. Once activated, the function takes priority, if the appliance is shut
down by disconnecting the power supply, when it is restarted the function
picks up from where it was interrupted. The function can be interrupted
before its end by putting the appliance in a condition other than OFF or else
by selecting DEACTIVATE FUNCTION from the relative menu.
Note: The temperature and increase values can be set to different values
only by qualified personnel, only if strictly necessary. The manufacturer
declines all responsibility if the parameters are incorrectly set.
