Special functions
Menu “7. Special functions” is used to set basic items and expanded functions.
The menu is closed by pressing “esc” or selecting “Exit special functions”.
6. - Special functions
Caution
Other than the time all settings may only be made by a specialist.
The suitable hydraulic variant for the speci c application is selected and set here (see „D.3. - Hydraulic variants / Schemes /
Systems“ on page 11). The associated diagram is displayed.
Settings range: 1-48 / Default setting: 1
6.1. - Program selection
Caution
Normally the program selection is made only once during initial commissioning by the specialist. Incorrect pro-
gram selection can lead to unpredictable errors.
With speed control the XTDC makes it possible to vary the speed of connected pumps.
6.2. - Speed control
6.2.1. - Variant
6.2.2. - Type of pump
The following speed variants are available here:
Off: There is no speed control. The connected pump is only switched on or off with full speed.
Variant V1: After the purging time the controller switches to the set max. speed. If the temperature difference T between
the reference sensors (collector and storage tank) is less than the set value, then the speed is decreased by one stage after
the control time elapses. If the temperature difference between the reference sensors is greater than the set value, then the
speed is increased by one stage after the control time elapses. If the controller has adjusted the speed of the pump down to
the smallest stage and the T between the reference sensors is T off, the pump is switched off.
Variant V2: After the purging time the controller switches to the set min. speed. If the temperature difference T between the
reference sensors (collector and storage tank) is greater than the set value, then the speed is increased by one stage after the
control time elapses. If the temperature difference T between the reference sensors is below the set value, then the speed is
decreased by one stage after the control time elapses. If the controller has adjusted the speed of the pump down to the small-
est stage and the T between the reference sensors is Toff, the pump is switched off.
Variant V3: After the purging time the controller switches to the set min. speed. If the temperature at the reference sensor
(collector) is greater than the setpoint to be set subsequently, then the speed is increased by one stage after the control time
expires. If the temperature at the reference sensor (collector) is less than the setpoint to be set subsequently, then the speed
is decreased by one stage after the control time expires.
Setting range: V1,V2,V3, off/default setting: off
Variant V4:
When the primary storage is loaded, speed control works as in V3.
When the secondary storage is loaded, speed control works as in V2.
Settings range: V1,V2,V3, Off / Default: Off
The type of speed controlled pump must be entered here.
Standard: Speed control for standard pumps.
0-10V: Speed control of e.g. High ef cency pumps by 0-10V signal.
PWM: Speed control of e.g. High ef cency pumps by PWM signal.
This function should only be activated by a specialist. Depending on the pump and pump stage used, the
minimum speed should not be set too low, because otherwise the pump or the system may be damaged. The
information provided by the relevant manufacturer must also be observed! If in doubt, the min. speed and the
pump stage should generally be set to high rather than too low.
Caution
The enumeration of the menus may vary from system to system.
