3.3.4.2 Pump modes in heating mode
Pump operation as a function of flow temperature
The heating pump can be set in various operating modes using diagnostics code "D.018".
Comfort : The pump is in operation if:
─ the "Summer mode" function is not active (see "D.023") and
─ the bridge (terminal 3/4 (VR 36) = 1) is available (see "D.016", "S.30") and
─ the target value via eBUS > 20 °C (see "D.005")
ECO: This pump mode is useful for removing residual heat after cylinder charging when the heat
demand is extremely low and large temperature differences exist between the cylinder charging and
heating mode target values. This prevents the living rooms from overheating.
Special features: After switching off the burner, the pump overrun and burner anti-cycling time are
started [1]. The pump overrun ends after, for example, 5 minutes [2] and the burner anti-cycling time
ends after another, for example, 15 minutes [3]. For target values > 20
°C, the pump is initially
switched on for a maximum of 5 minutes. If the flow temperature then remains above the target value
of -5 K, the pump is prevented from switching on for 25 minutes [4] - [5]. After this time, the pump is
activated again for 5 minutes to circulate the water again. If the flow temperature falls below the
target value of -5 K during this time, the burner switches on immediately. Otherwise, after the 5
minutes [6] has passed, the pump will be blocked again for 25 minutes.
