CAUTION!
Before commencing, disconnect the
device from the mains. There are parts that
carry mains voltage behind the cover. Never
leave unsupervised when it is open. (Prevent
non specialists and especially children from
gaining access to it.)
Never remove this product from the electrical
baseplate. Disconnect from mains supply in the
event of any damage to any buttons. Do not
use sharp tools to push any button.
When the thermostat is in the AUTO mode, it will operate according to the
times and temperatures that have been programmed. The user can select
from 6 dierent programs per day - each with a time and a temperature.
There is no OFF time, only a higher and a lower temperature setpoint.
If the user wants the thermostat to be OFF at a certain time, set the
temperature for this time to be low. The thermostat will turn ON if the room
temperature is lower than the setpoint for the current period.
Example: If P1 is set to be 21˚C at 6am, and if P2 is set to be 10˚C at 8am, the
thermostat will look for the temperature to be 21˚C between 6am and 8am.
