speed
•If the key is pressed for more than 1 second, the value changes with a
constant acceleration to a speed of ten per second

switchoff on SET value
•Regulation is executed each minute or at the end of all set and programing
state at 45 second period end
•Relays command uses following logic:
—Tset - Tmeas > 0.3 then relays ON
—Tset - Tmeas <= 0 then relays OFF
—Tset = temperature corresponding to current time setting
—Tmeas = measured environment temperature
BATTERY REPLACEMENT
•When batteries are near to
discherge all display flashes
while executing all
functions
•At this point substitution is
recommended
•Slide to the left the upper

to normal operation values.
If low batteries are placed, wait time can be much longer
