)
Please note:
In the event of a power failure, the system will remember the current operating mode (cool / heat mode).
However, the internal thermostat always starts up in the Off state, and with the default temperature
setpoint (25.0 °C)
.
Temperature Correction
To compensate for any possible temperature deviation due to cold or heat sources close to the
location of the probe, a correction factor (offset) can be defined. This factor will be applied to the
temperature measured by the probe in order to calculate the actual room temperature.
The correction factor can be adjusted in multiples of 0.5 °C in Settings
→
Internal Thermostat. Room
temperature is calculated as follows:
T
room
= Temperature measured by the probe + Correction factor
This parameter is not available if the room temperature is read from an external KNX device.
Internal Temperature Stabilization
When using the integrated temperature sensor of the HC1-KNX touch panel, a certain time (typically
60 minutes) must elapse since system startup for the internal temperature to stabilize and the
temperature reading to be reliable.
During the stabilization period, the internal thermostat is not yet operational. Therefore, it is not
recommended to adjust the correction factor during this period of time (if the user tries to modify the
correction factor during this period, the system will pop up a warning message, but will allow the user
to proceed if they wish to do so).
This stabilization period is only applicable to the HC1-KNX panel, and only if the thermostat function is
configured to use the integrated temperature sensor.
4.11 Date and Time
Iddero touch panels feature an integrated real time clock (RTC). The real time clock is used to display
the current date and time, as well as to control time schedules and the presence simulation function.
The real time clock includes a backup battery to keep the system date and time in case of power
failure.
The system date and time can be set manually from the System Date and System Time pages, in
Settings
→
System.
If the installation includes a device that can periodically send the date and time to the KNX bus (such
as a DCF 77 receiver), the touch panel can be configured to automatically synchronize the internal
date and time information with this device by enabling the “Synchronize date / time with external clock”
parameter during the configuration stage.
Additionally, the Iddero touch panel can also be used as a date and time master for other KNX
devices. The panel can be configured to periodically send the date and time to the KNX bus (once per
minute, once per hour, or once per day), by means of the “Transmit time of day” and “Transmit date”
configuration parameters.
