Installation Guide ECL Comfort 210 / 310, application A2665.5 Flow / power limitHeating circuitA flow or heat meter can be connected to the ECL controller inorder to limit the flow or consumed power. The signal from theflow or heat meter is a pulse signal.When the application runs in an ECL Comfort 310 controller, theflow / power signal can be obtained from a flow / heat meter viathe M-bus connection.The flow / power limitation can be based on the outdoortemperature. Typically, in district heating systems a higher flow orpower is accepted at lower outdoor temperatures.The relationship between the flow or power limits and the outdoortemperature 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 'Highlimit Y2'. Based on these settings, the controller calculates thelimitation value.When the flow / power gets higher than the calculated limit, thecontrollergraduallyreducesthedesiredflowtemperaturetoobtainan acceptable max. flow or power consumption.Flow / power limitationHighlimitY2LowlimitY1° C15-15Outdoortemp.Low T out X2 HighToutX1Flow/powerlimitation LimitDesired flowtemp.° CTimeIf the ‘Adapt. time’ is too high, there is a risk of unstable control.DHW circuitA flow or heat meter can be connected to the ECL controller inorder to limit the flow or consumed power.
