7. Special Functions
Used to set basic items and expanded functions.
The settings in this menu should only be changed by a specialist.
Sensor Calibration
Deviations in the temperature values displayed, for example. due to cables which are too long or sensors which are not posi-
tioned optimally can be compensated for manually here. The settings can be made for each individual sensor in steps of 0.5 °C.
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect meas-
urement values can lead to unpredictable errors.
Commissioning
Starting commissioning help guides you in the correct order through the basic settings necessary for commissioning, and
provides brief descriptions of each parameter in the display. Pressing the ‚esc‘ key takes you back to the previous value so you
can look at the selected setting again or adjust it if desired. Pressing ‚esc‘ more than once takes you back to the selection mode,
thus cancelling the commissioning help see " Commissioning help " on page 13
May only be started by a specialist during commissioning! Observe the explanations for the individual parameters in
these instructions, and check whether further settings are necessary for your application.
Factory Settings
All settings can be reset, returning the controller to its delivery state.
All of the controller‘s parametrization, statistics, etc. will be lost irrevocably. The controller must then be commissioned
once again.
Mixer
Here individual parameters for mixer control can be changed.
Turn Time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow
temperature
Pause Factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is ‚1‘, the normal pause time is
used, ‚0.5‘ will use half the normal pause time. Setting the pause factor to ‚4‘ would quadruple the pause time.
Increase
If the temperature rises very fast, this value is added to the measured flow temperature so that the mixer’s reaction is stronger. If
the measured temperature does not rise any more, the measured value is used again. The measurement occurs once every
minute.
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect meas-
urement values can lead to unpredictable errors.
Room Controller heating circ. (X)
The settings necessary for the optional room controller RC21 are set in this menu. The three modes, ‚Continuous Day‘, ‚Continu-
ous Night‘ and ‚Time controlled/Automatic‘ can be switched at the RC21. Additionally the reference temperature of the flow can
be parallel translated by turning the control wheel. If the wheel is set to minimum, only the minimum values that can be set in the
protective functions menu will be used.
