ENG
When starting the system, it is necessary to determine the minimum rotation rate by which
the bypass pump R6 enables minimum flow. First use a switch to set the maximum or at
least medium intensity of pump operation. In the controller, select the manual operation
mode (page 27) in check at which rotation rate the pump can provide system flow. Save the
minimum rotation rate of the pump with parameter S6.11.

SENSOR SIMULATION
The WDC controller has a special function installed, which enables simulations of all sen-
sors. With the help of this function, users can test controller operation. This function is in-
tended for the case of start-up, maintenance or testing of a controller.
Sensor simulation is activated by selecting the screen with hydraulic scheme display with the
button. Press the button and hold it for 10 seconds. The controller will switch over
to the simulation operation mode
Move between sensors by pressing the button. With buttons and set the
temperature value for each selected sensor. The simulated sensor mark will change from T
to S.
Simulation operation mode is deactivated by pressing the button for 10 seconds or if no
button is pressed for more than 5 minutes.
