4.1 Control selection

There are

4 types of control are possible

depending on the value of parameter A07.

●

On/Off

: In-series control by activation of fan stages.

●

Variable speed control

: Fan speed control by EC motor.

●

Mixed 1:

Variable speed control on one stage then activation of the other On/Off stages depending on the speed of the EC fan

●

Mixed 2:

Variable speed control on one stage then activation of the other On/Off stages when the EC fan is at 100%

●

Mixed 3:

Variable speed control on one stage then activation of the other On/Off stages depending on the temperature and the

temporization

4.1.1 On/Off control (stages)

This control is used to control the fan stages, its configuration is "IN SERIES".
Control can be for

condensation pressure or temperature.

Each circuit has a control loop and can have different control setpoints but the number of stages is the same.
There are 2 types of On/Off control:

A156 :

A158 :

A160 :

A159 :

For drycoolers from V07

The diagram below illustrates the operating principle:

- When the fluid temperature (measured) is

between A121-A106 and A121+A106, the fan

stages are not active.

- When the fluid temperature < A121-A106 and the

temperature continues to drop for a duration < A108
the control system will shut off a control stage.

When the fluid temperature > A121+A106 and

the temperature continues to rise for a duration >
A107 the control system will activate an additional
control stage.

● For the cond drycooler before

V07 on the board

- The fan stages are engaged

according to the stage hysteresis

and stage ∆.

- Each control loop has its own stage

hysteresis and its own stage ∆
