Send setpoint cyclic (0 – inactive, min)
Options: - 0 .. 60
If the current value is to be sent cyclically independent of a change,
the parameter "Send setpoint cyclic" must be set to a time. This may be
necessary, for instance, with a higher-level boiler that expects to receive
setpoints and current values within a certain time period. If values are not
received, a predefined supply line temperature is set that is no longer
oriented on actual demand.
Measurement of room temperature
Options: - Interior
- Exterior
- Interior and exterior
This parameter is used to set the measurement of the current temperature.
It can be measured "Interior," "Exterior" or "Interior and Exterior". Internal
measurement means that the temperature is taken directly from the room
thermostat. For external measurements, an additional temperature sensor is
used and is sent to the room thermostat via 2-byte communication object. If
you are measuring current temperature internally and externally, the room
thermostat determines the current temperature from the combination of
temperature values defined in the "Emphasis internal/external" parameter.
An additional sensor may need to be added for larger spaces.
Weighting interior / exterior
Options: - 10% / 90%
- 20 % / 80 %
- 30 % / 70 %
- 40 % / 60 %
- 50 % / 50 %
- 60 % / 40 %
- 70 % / 30 %
- 80 % / 20 %
- 90 % / 10 %
The "Weighting interior / exterior" specifies whether the internal temperature
sensor for the ambient temperature controller is included in the control.
If, for instance, the parameter is set to 60%, the current temperature is 60%
of the temperature measured internally and 40% of the value obtained
externally.
Monitoring temperature measurement
Options: - Yes
- No
The "Monitoring temperature measurement" parameter defines whether
the internal and, if connected, external temperature sensors are to be
monitored.
