Thermal Bypass

In this dialog you configure thermal bypasses. The thermal bypass opens as soon as there is a drop below the minimum temperature at the initial node of the control valve (which must be in the flow and/or KLB leader).
  • Control name – Name of the regulation, which must be unique within the regulations.
  • Control valve – use this Combination field to select the valve to be regulated.
    Note: The field is deactivated as soon as the control is in use by a network calculation.
  • Min. temperature – The minimum temperature which is to be maintained. Opens the bypass opens as soon as there is a drop below this temperature.
    Note: In order to establish a thermal bypass between flow and return, set a valve with the initial node into the flow, with the end node into the return. As soon as there is a drop below the minimum temperature, the valve opens. If the too low temperature was caused by too small velocity of flow and thus by too strong cooling down of the flow, the temperature at the initial node rises.
