In this case, the standby or night setpoint temperatures will always shift together with the temperature
increase/decrease resulting from the local control during the adjustment of the basic setpoint temperature or the
dead zone. After the reprogramming with the ETS, the originally parameterized values can be accepted again.
The following applies:
T
standby setpoint heating
T
night setpoint heating
In case of a two-stage control the setpoints of the additional stage are always derived dynamically from the
setpoints of the basic stage. The temperature setpoints of the additional stage are predefined by the stage offset
which is parameterized in the ETS. The stage offset cannot be adjusted in the local control mode.
As far as a change of the basic setpoint temperature is concerned (when a new comfort setpoint temperature
value for heating is being received by communication object no. 26), there basically two cases to be distinguished:
- Case 1: The basic setpoint adjustment is permanently adopted,
- Case 2: The basic setpoint adjustment is only temporarily adopted (default).
Via the "Adopt basic temperature setpoint permanently" parameter on the "Room temperature controller function
/setpoints" parameter page, it is possible to determine whether the changed basic temperature value shall be
stored in memory permanently ("Yes") or only temporarily ("No").
Case 1:
If the basic temperature setpoint is changed, it will be permanently stored in the room temperature controller's
EEPROM. The newly adjusted value will overwrite the basic temperature originally parameterized with the ETS!
It should be noted, however, that frequent adjustments of the basic temperature (e.g. several times a day) can
affect the product life of the device as the non-volatile memory is designed only for less frequent write access.
Thus the basic setpoint received by the object remains in memory even after a bus voltage failure.
Case 2:
The basic setpoint received via the object stays only temporarily active in the current operating mode. In case of a
bus voltage failure or following a switch-over into another operating mode (e.g. comfort followed by standby), the
basic setpoint set via local control or received via the object will be discarded and replaced by the value which
was originally parameterized in the ETS.
Notes:
- Since the setpoint temperatures for the "standby" and "night" operating modes or the setpoints for the "cooling"
control option are derived - in consideration of the increase, decrease or dead zone values that are
parameterized in the ETS - from the basic setpoint temperature for "heating", these setpoint temperatures will
shift linearly by the change of the basic setpoint value.
The temperature setpoints for the standby or night mode or "cooling" comfort mode (dead zone) will always be
stored in the non-volatile EEPROM.
- It has to be pointed out that temperature setpoints can only be changed or stored via the "Basic setpoint"
object, if it was enabled in the ETS.
