Control modes
flexotron®400 can be configured to any one of the following control modes.
1. Temperature control.
The temperature at the sensor is kept at the setpoint value by controlling the
output signals on AO1 and AO2. A single PI control loop is used.
Three different temperature ranges can be selected:
-
20…+60, 20…100, 60…140°C
2. CO
2
control.
The CO
2
-value at the sensor is kept at the setpoint value by controlling the output
signal on AO1. A single PI control loop is used.
3. General control.
The actual value at the sensor is kept at the setpoint value by controlling the
output signal on AO1 and AO2. AO1 is used for positive, direct-acting control,
AO2 for negative, reverse-acting control. A single PI control loop is used.
4. Pressure control.
The pressure at the sensor is kept at the setpoint value by controlling the output
signal on AO1. The AO1 inverted signal is received from AO2. A single PI control
loop is used.
5. Pressure control with outdoor compensation.
The pressure at the sensor is kept at the setpoint value by controlling the output
signal on AO1. The AO1 inverted signal is received from AO2. The setpoint is
automatically adjusted according to the outdoor temperature. A single PI control
loop is used.
