11d) Constant temperature
In this mode, inverter ensures a constant temperature in the system. For this operation mode, a temperature sensor
should be placed at the location where temperature is to be controlled.
Note: For heating system, set 6. FINE TUNING parameter 6.03 to Positive and for cooling system, set 6. FINE
TUNING parameter 6.03 to Negative.
Caution: Use correct type of temperature sensor depending on the application.
11e) Differential temperature
In this mode, inverter ensures a constant differential temperature in the system. This operation mode requires
either a differential temperature sensor or two temperature sensors of same temperature ratings.
Caution: Use correct type of temperature sensor depending on the application.
Note: For temperature control mode, proportional and integral control setting may have to be adjusted according
to the distance between the temperature sensor and the heat exchanger.
12 - START-UP WIZARD
The first time you connect the voltage to your unit, a start-up wizard will run in which you can configure the basic
parameters to be able to start up the pump unit. For operation modes with more than 1 pump, this wizard only runs
on one of the units regardless of the total that are connected.
While using this wizard the red LED will blink indicating that this process is under way.
You must choose between the different operating modes of the
system, which are:
MODE A: CONSTANT PRESSURE
MODE B: DIFFERENTIAL PRESSURE
MODE C: FIXED SPEED
MODE D: CONSTANT TEMPERATURE
MODE E: DIFFERENTIAL TEMPERATURE
