Control Modes - Regin OPTIGO OP5U Mode D'emploi

Control modes

Optigo 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. The setpoint can
be set directly from the display or via an external setpoint device.
A single PI control loop is used.
The analogue outputs can be configured to the following combi-
nations:

Level 1.6 of the menu is used for selecting the temperature operating
range. Here, it is possible to select:
Low (1) -20...+60°C Min. setpoint= -18, max.= +60
Medium (2) 20...100°C Min. setpoint= 22, max.= 100
High (3) 60...140°C Min. setpoint= 62,max.= 140
2. CO control

3. General control
The setpoint at the sensor is returned by controlling the output
24 V AC
signals on AO1 and AO2. AO1 is used for positive control, AO2 for
negative control. A single PI control loop is used.
If you want to max. limit the humidity, connect a HMH humidistat in
+ series with the start signal to terminals 41 and 42.

The pressure at the sensor is kept at the setpoint value by
controlling the output signal on AO1. A single PI control loop is
0...10V
used. The AO1 inverted signal is recieved from AO2.

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 setpoint is automati-
cally adjusted according to the outdoor temperature. A single PI
control loop is used. When this control mode is used, the
temperature range is adjusted down to the low setting
(-20...+60°C). The AO1 inverted signal is recieved from AO2.
