The parameter is visible if the option ―External temperature sensor‖ is selected with the
parameter ―type of indoor temperature sensor‖. The parameter is used to define the time that the TFT
device monitors the external temperature sensor. If the TFT device does not receive a special
telegram from the external temperature sensor during the time, it will judge that the external
temperature sensor goes out of order, and start using the internal temperature sensor. The monitoring
time will be recounted when the TFT receives a new telegram from the external temperature sensor.
Option: 1…120min
Note: The monitoring time in the TFT should be at least twice as long as the cyclical
sending time of the external temperature sensor to avoid missing telegrams.
In the case of selecting the external temperature sensor, after bus voltage recovery or
reset, if the TFT has not received a temperature measure value from the external sensor, it
will not show the indoor temperature, until received a temperature or the monitor time has
passed.

Parameter “Indoor temperature sensor calibration = entry*0.1”
Here set indoor temperature calibration, i.e. the TFT will correct the temperature that the indoor
temperature sensor detects to avoid the measure temperature with the actual temperature is too large
error. Option: -128…127
If the correction value is 50, the sensor detects a temperature of 20
℃
, then the corrected
temperature is 20+50*0.1=25
℃
.

Parameter “Temperature units of measurement”
The parameter is visible if the option ―External temperature sensor‖ is selected with the
parameter ―type of indoor temperature sensor‖. It is used to set the indoor temperature units of
measurement. Options:
Celsius (C)
Fahrenheit (F)
If selecting the internal temperature sensor, the temperature units of measurement is defined as
Celsius (C).

Outdoor temperature setting
Parameter “Outdoor temperature display”
The parameter defines whether the outdoor temperature display is active. Options:
Active
Inactive
If selecting ―Active‖, the following parameters will be visible.
