4.11 Handling system faults

If the room temperature exceeds or drops below the measuring range, i.e. above

49 °C or below 0 °C, the limiting temperatures blink, e.g., 0 °C or 49 °C.
In addition, the heating output is activated if the current setpoint is not set to Off,

the thermostat is in heating mode and the temperature is below 0 °C.
For all other cases, no output is activated.
The thermostat resumes Comfort mode as soon as the temperature is within the

measuring range.

●

If the built-in temperature or humidity sensor fails and no external temperature

sensor is connected, fault message Er1 is displayed on the thermostat. If

EEPROM is damaged, fault message Er2 is displayed on the thermostat.

Replace the thermostat to measure the room temperature.

●

If the external / remote temperature sensor fails and no external sensor is

connected, if input X1/X2/U1 is configured as AI except room temp external

sensor/return (AI), fault message Er3, Er4 or Er5 is displayed on the

thermostat. Check related sensor input terminals.

4.12 KNX communications

RDG2..KN thermostats support communications as per KNX specifications.

S-Mode

Standard mode; engineering via group addresses.

LTE-Mode

Logical Tag Extended mode, for easy engineering, is used

together with Synco.

4.12.1 S-Mode

This mode corresponds to KNX communications.
Connections are established via ETS by assigning communication objects to group

addresses.
