Additional functions
• After batteries are installed, the controller displays the temperature from
the external temperature sensor.
• When the external sensor is connected (the terminal block is located
under the enclosure), the controller automatically takes the readings
from that sensor.
• If the external sensor is disconnected or defective, the controller goes into
the emergency mode (dashes are shown as the measured temperature),
which results in the CH pump shutting down until the defect is eliminated.
This is intended to protect the heating system from overheating. In order
to leave the emergency mode, connect the external temperature sensor
back or reset the controller by taking out the battery until the display
switches off. After this procedure is completed, the controller displays
the temperature measured by the internal sensor.
