Basic Settings 19
In the print-out the first value is always the current temperature and the following two values
are the lower and upper alarm limits respectively (=acceptable temperature range). If a
particular sensor is not connected or if its cable is broken, the temperature value will be less
than -67 degrees of Celsius.
T1:+31.0 HC device +7.0..+40.0 T2:+22.7 Indoor 1 +10.0..+50.0 T3:+21.5 Indoor 2
+10.0..+40.0 T4:+18.0 Garage +5.0..+50.0 T5:+14.4 Outdoor -30.0..+40.0
Setting alarm limits
# T x y y z z
x = Temperature sensor number (1 through 4)
yy = Lower alarm limit
zz = Upper alarm limit
The alarm limits must be given in whole numbers or with one decimal if need be. A negative value can
be formed by placing a minus sign in front of the value. The confirmation message received in response
to this command is the same as in asking the temperature, for example, T1: +23.5 –30..45. Alarm
message is sent immediately when temperature rises above or drops below the set alarm limit value. In
other words, the temperature sensor operates like normally open contact. It should be noted that an
alarm message is sent every time a specified alarm limit is exceeded.
2.7.1 Internal (Device) Temperature Sensor T1
Your HouseControl hosts one internal temperature sensor T1 situated in the right bottom corner of the
unit’s circuit board. It measures the temperature from the immediate surroundings of the unit.
) Internal temperature sensor T1 can have over ten degrees higher values than an external
temperature sensor. This phenomenon occurs because the sensor is located inside the unit’s box
where heat is transmitted along the copper layers of the circuit board.
