Local temperature adjustment
The temperature setpoint can be adjusted both by the communication
object “Local adjustment of temperature" (obj. 011) and by the user
panel. The local adjustment of temperature object can adjust the
actual temperature setpoint by +/-10ºC.
The user panel temperature adjustment can maximum be +/-3ºC. The
adjustment done on the panel will update the local adjustment of
temperature communication object.
The heating system will be turn on at 20.5ºC - 3ºC = 17.5ºC and off
at 18.0ºC in comfort mode with the parameters shown in Figure 9.
The cooling system will be turned on at 21ºC - 3ºC + 2ºC + 0.5ºC =
20.5ºC and Off if the temperature drops below 20.0ºC.
It is possible to limit the temperature adjustment up or down, for example to +3 to
-1C, +1.5C to -0.5C and +0.5 to -0C. The LED indi3 to -3 on the user panel
will still show the full scale, so the user will not notice the limitation.
The temperature sensor includes a filtering algorithm that will eliminate temperature
rise after the user panel has been touched. The temperature measurement will
remain unchanged for 3 to 8 minutes after the buttons on the user panel has been
operated.
If the panel is removed, all regulator outputs will be set to “0” one time, and the
actual temperature is send 0ºC.
The “Self test” object will indicate the error and will be transmitted as “1”.
