5.5 Flow / verm. grens
A flow or energy meter can be connected (M-bus signal) to the ECL
controller in order to limit the flow or consumed power.
The flow / power limitation can be based on the outdoor
temperature. Typically, in district heating systems a higher flow or
power is accepted at lower outdoor temperatures.
The relationship between the flow or power limits and the outdoor
temperature is set in two coordinates.
The outdoor temperature coordinates are set in 'High T out X1'
and 'Low T out X2' .
The flow or power coordinates are set in 'Low limit Y1' and 'High
limit Y2' . Based on these settings, the controller calculates the
limitation value.
When the flow / power gets higher than the calculated limit, the
controller gradually reduces the desired flow temperature to obtain
an acceptable max. flow or power consumption.
