F.A.Q.
What does the temperature value on the display actually represent?
If no external temperature probe is enabled during ETS/Easy Controller programming,
the value on the display is the temperature detected by the sensor built into the
thermostat.
If, however, an external temperature probe (of the KNX or NTC type) has been enabled,
the thermostat shows the average between the values detected by the probe and the
sensor, using a variable weight between 10% and 100% (which can be defined via ETS).
The temperature shown by the display measured by the internal sensor does not
vary also in the face of temperature changes. Why?
As a result of an intensive use of the device (for instance during programming stages),
if back-lighting is enabled, there could be minor changes in local temperatures.
Therefore, in order to guarantee measurement accuracy also under these conditions,
the device inhibits updating the measurement for a few minutes.
How is humidity measured?
The device is not equipped with a built-in humidity sensor and, therefore, the relative
humidity value must be provided by an external KNX sensor (e.g: GW1x762H).
What happens to the time band set on the thermostat if auxiliary power supply
(12-24VAC/DC) fails and is reset?
The thermostat is equipped with a power accumulation system to keep the time (max.
1h) in the event of auxiliary power supply failure. If the time setting is lost, it can be reset
manually, or automatically via the BUS (defined via ETS), from a KNX device (timed
thermostat, weather station, Master, Internet Gateway, etc.).
