The thermostat displays
measured room temperature.
Note:
If you are using the DT300RF pack , the pairing between the thermostat and the receiveris already done.
During the pairing process, please make sure the thermostat and the receiver are at least 1 meter from each other.
If you want to re-pair the devices with each other, follow the steps below:
To exit Installer Mode, wait 10 seconds, the thermostat will automatically return to the main screen.
Important note:
The communication radius of the thermostat with the receiver is of maximum 100m, in
open space. In built space, with various obstacles (eg walls, floors, metal structures, furniture elements), the
communication radius will be significantly reduced. RF communication can be disrupted by local factors, such as
GSM antennas, radio frequency devices or toys, or other equipment that produces electromagnetic interference.
Receivers for the boiler must be powered from a stable voltage source, without frequent interruptions or voltage
fluctuations (outside the standard tolerance). The manufacturer is not responsible for identifying or combating
the effects of local disturbances.
After 2 seconds, the new temperature
setpoint will be overwritten.
The thermostat will display the measured temperature
again. The heating mode icon will appear if the temperature
setpoint is higher than the measured temperature.
Move the left switch to the OFF
position with a quick motion and
back to the ON position
Press and hold PAIRING / TEST button
behind the back cover cover for 3 seconds.
Press and hold PAIRING / TEST button
behind the back cover cover for 3 seconds.
When the thermostat enters sync mode,
the screen will display S Y + a digit.
The pairing process can take up to 9 minutes.
Once devices are successfully paired,
the LED indicator will turn permanently green.
Press the RESET button under the
back cover (you can use a paper clip),
the thermostat will reset and restart
automatically.
To insert and replace the batteries, follow the steps below:
1. Unlock the battery compartment.
2. Push the battery holder at the bottom of the thermostat
3. After adding or replacing the batteries, re-insert the battery
holder.
The green LED will start blinking,
which will confirm that the receiver
has entered the pairing mode
Press three buttons at the same time
for 3 seconds
Make sure that the receiver is
disconnected from the
power supply
and the switches on it are in the
AUTO and ON positions.
Then connect the receiver to the
power supply and wait for
the green LED to glow continuously.
