Activator

This BC creates a 1 or 0 based on the relevant input signal. It can be used as a 2-point measuring control strategy for a thermal store.

Image Added

Comparison

This BC creates a 1 if the input in A is larger than B and a 0 if B is larger than A.

Image Added

Difference

This BC is a simple mathematical difference between A and B.

Image Added

Hysteresis and integrator

This BC uses a hysteresis or integrator function on the input signal.

Image Added

Minimum & Maximum

This BC gives either the minimum or the maximum of all the signals connected on the input.

Image Added

Multiply

This BC multiplies all the input signals connected.

Image Added

Negative

This BC makes the signal negative.

Image Added

Piecewise linear function & function expression

This BC uses functions on the input signal, which can be changed to fit the needs of the project.

Image Added

Scaling and truncating

This BC allows for scaling of values.

Image Added

Sum

This base circuits sums all the inputs together.

Image Added

Low pass circuit

The Low pass circuit puts a time delay on a value change.

Image Added

Delay

This BC puts a delay on the signal. This can be used to let a pump run 5 minutes longer for example.

Image Added

Loop Back

This BC is necessary if you want to loop a signal back (in the next timestep)
Here is an example in which the resulting signal to control the boiler is looped back towards the controller:
