Chronothermostat with Humidistat User Manual
Choose the regulation band value as follows:
• broad band (5°C) for systems with high thermal gradient
• narrow band (0.5°C) for systems with low thermal gradient
BATTERY REPLACEMENT
•
When the battery is almost
flat, the whole display
flashes, although it will
continue to carry out all
functions.
For lower battery voltage,
the instrument will reach
the flat battery status, which
causes the display to switch
off, a reduced consumption
and the suspension of all
functions except the clock.
Operation in this status may
continue until the battery
keeps a voltage such to
allow operation to the
microcontroller.
The replacement of batteries must take place within maximum time of one minute in
conditions of flashing display.
Beyond this time, date and time will be lost and must be reset upon next activation.
However, the executed programs will remain memorized.
The use of strictly alkaline batteries is recommended.
Attention
when the battery is reinserted, the instrument does not restart operation
immediately; a period of time varying between 5 and 10 seconds must be waited,
during which the internal voltage regains normal operation values.
If the flat or nearly flat battery is removed and put back again, the waiting time
could be much longer.
