Temperature Simulation Mode; Connection Of A High-Efficiency Pump With An External Control Signal - OEG KSW-E series Bedienungsanleitungen

TEMPERATURE SIMULATION MODE

KSW-E*, KSW*, KS2W* controller has a special function which enables user, to simulate
temperature for each sensor and through that study behaviour and operation of the con-
troller. This function is intended for cases of maintenance, malfunctions or suspected
false controller operation. Simulation mode is activated in the following way.
Press key to select screen with display of hydraulic scheme. Now press and hold
key for 10 seconds. Controller switches to simulation mode. Press button
to scroll between sensors and button
sor. Controller changes temperature symbol from T to S, when the temperature is simulat-
ed. Output is activated accordingly to selected scheme and simulated or actual tempera-
tures.
Simulation mode can be cancelled by pressing button
button is pressed.
CONNECTION OF A HIGH-EFFICIENCY PUMP WITH AN EXTERNAL CONTROL
SIGNAL
The KSW-E*, KSW*, KS2W* controller enables the regulation of high-efficiency pump
speed with PWM external control signal or 0÷10 V. This type of speed control is activated
by setting the parameter S3.1=2 or 4 for bypass pump R2 and S3.7=2 or 4 for R3*. After
connecting the pump, you have to set the parameter S3.4 to S3.6 for the R2 pump and
S3.10 to S3.12 for the R3* pump.
* Depends on the controller model.
