Continuous Flow

If the heating control strategy macro was set for “continuous flow”, the outputs “ButFlyVlv” and “PumpCmd” will stay on, as long as the position number of the heating output module equals “1” within the preferred group. The “continuous flow mode” depends on the setting of the specific parameter within the control strategy module (see control strategy module help file).

The function provides a continuous circulation through the primary heating system, most of the times for adequate temperature measuring or safety requirements.


NOTE1: If the boiler with position number “1” is switched off by a “VESFailure”, a “PumpOffAlarm” or one of the inputs “AlarmIn” or “BurnerAlarm” becomes true (=1), or when it is manually switched off by the “ManSwCond” input (ManSwCond = 0), then the “continuous flow” operation will be effective on the next boiler.


NOTE2: If the leading heat generator setting SYS-07 = 1, which means that the burner, pump and valve outputs will stay on during alarm, the leading heat generator and the continuous flow will not be transmitted to the next heat generator in the sequence.


The continuous flow mode will be transmitted between the heat generators and heating strategy via a communication signal.
