Overcurrent Protection; Control Modes - Regin OPTIGO OP10 Anleitung

Overcurrent protection

The controller OP10-230 shall be protected by a fuse in the building
installation. The maximum load of the controller, 1000 VA, suggests a
6 A fuse.
Follow table 1 below for connection.

For best protection against disturbances, a shielded twisted-pair cable
should be used for wiring the sensors. Ground the shield at one end.

Control modes

Optigo can be configured to any one of the following control modes:
1. Supply air temperature control
The supply air temperature is kept at the setpoint value by controlling
the output signals on AO1 and AO2. A single PI control loop is used.
Connect the sensor to AI1, even if only using a room sensor.
2. Supply air temperature control with outdoor compensation
The supply air temperature is kept at the setpoint value by control-
ling the output signals on AO1 and AO2. A single PI control loop is
used. The setpoint is automatically adjusted according to the outdoor
temperature.
3. Cascade connected supply air control with room / extract air
temperature influence
An offset in room temperature will adjust the supply air temperature
setpoint so as to eliminate the room temperature offset. Control
loops with PI-control are used. The supply air temperature is
minimum and maximum limited. A supply temperature sensor and a
room/extract air sensor must be utilised.
4. Radiator circuit control with outdoor curve
The water temperature setpoint is changed according to the outdoor
temperature. A single PI control loop is used. A room temperature
sensor can be added to give corrective action if the room tempera-
ture differs from the setpoint. Without a room sensor, the setpoint is
a parallel displacement of the curve. When using a room sensor, the
setpoint is a room setpoint. This is automatically set when confi-
guring control mode 4.

5. Domestic hot water control
The water temperature is kept constant by controlling the output
signal on AO1. A single PID control loop is used.
Control modes 1, 2 and 3
For control modes 1, 2 and 3, the analogue outputs can be configured
to the following combinations:

Note: For control modes 1, 2 and 3, the input for fan indication (DI1)
must be connected in order to start the control function, otherwise an
alarm, AL3, will be generated. The input must "follow" the fan output,
i.e. if the output closes, the input must also close.
