The thermostat has entered the Emergency
Timed Mode (described below).
The screen
continuously displays "oFF" or flashes "t"
and the time remaining until the next load is switched on/off.

short circuit of
the sensor circuit
Possible cause: damage to the sensor and its chain, incorrect sensor type selected in the thermostat settings, the temperature measured by an analog sensor has gone beyond the range (see Technical data).
Required action: check the integrity of the sensor and the absence of mechanical damage to its chain, check for nearby power wires. Check the correctness of the colors during the connection of the digital sensor. Make sure the appropriate type is selected in the sensor settings.
Emergency Timer Mode This mode ensures the operation of the load in case of detector damage: in a 30-minute cyclic interval, the load is switched on for the set time, and the load is switched off for the rest of the time. The load operation time can be set in the range from 1 to 29 minutes using the "+" or "–" buttons. The screen will then display "t" and the time remaining until the next on/off. From the factory, the Mode value is "oFF", the load is permanently off. To make the load run continuously, increase the time to a maximum of "on", or to turn it off completely to a minimum of "oFF".
