If selecting ―active‖, the objects ―date‖ and ―time‖ will visible, the date and the time can be
modified via them.
Temperature setting
The following parameters are used to set temperature display in the TFT operation system.
Parameter “Temperature display units”
Here set temperature display units. Options:
Celsius (C)
Fahrenheit ( F)
1.
Indoor temperature setting
Parameter “Type of indoor temperature sensor”
Here set the type of indoor temperature sensor. Options:
Internal temperature sensor
External temperature sensor
If selecting ―Internal temperature sensor‖, measure the indoor temperature via the temperature
sensor in the TFT device, and the measure value can be sent or read to the bus via the object ―Indoor
actual temperature‖ and can be displayed in the TFT operation system.
If selecting ―External temperature sensor‖, measure the indoor temperature via the external
temperature sensor, the TFT receives the measure value via the object ―Indoor actual temperature‖
from the external temperature sensor and displays it.
The internal temperature sensor is built-in the TFT device. The TFT will generate heat during
working, this may affect the sensor to measure temperature, and the measure value may inaccurate.
If you require a more accurate temperature, you can select to use the External temperature sensor,
and it can measure indoor temperature, and send the measure value to the TFT, then the TFT will
display the temperature.

Parameter “Indoor temperature change send at (Celsius)”
The parameter is visible if the option ―Internal temperature sensor‖ is selected with the
parameter ―type of indoor temperature sensor‖, it is used to set how much the door temperature
change, the related object will send the current temperature to the bus. Option:
Do not send
0.5
1
…
5
If selecting ―Do not send‖, the measure temperature will not be sent to the bus automatically,
unless via the object ―Indoor actual temperature‖ read it.
With the setting ―3‖, when the temperature changes of 3
℃
, the object ―Indoor actual
temperature‖ will send out the current temperature on the bus.
