Circulating pump cycling (1661)
To save energy, the circulation pump is switched on for 10 minutes and off
for 20 minutes within the release time.
Circulation setpoint (1663)
If sensor B39 is placed in the domestic water distribution line, circulation
pump Q4 is switched on as soon as the sensor value falls below the set
value. The pump then runs at a fixed rate for 10 minutes or longer until the
setpoint has been reached again. There is always a fixed difference of 8 K
between the setpoint for the domestic water storage tank and the setpoint
for sensor B39 (program no. 1663). This is intended to ensure that the
circulation setpoint can also be reached and the circulation pump does not
run indefinitely.
Example 1
DHW setpoint: 55 °C (nominal setpoint)
Circulation setpoint: 45 °C
→ The circulation pump switches on if the sensor value falls below 45 °C,
and runs for at least 10 minutes.
Example 2
DHW setpoint: 50 °C (nominal setpoint)
Circulation setpoint: 45 °C
→ The circulation pump switches on if the sensor value falls below 42 °C
(50 °C - 8 °C), and runs for at least 10 minutes.
Optg mode changeover (1680)
Using external switching above the entrance H1 it can be selected into
which operating mode is switched into.
None
: The external changeover does not affect the DHW operating
mode.
Off: DHW is switched to the operating mode "Off".
On: DHW is switched to the operating mode "On".

Consumer circuits/swimming pool circuit
Consumer circuits/swimming pool circuit
In addition to the heating circuits HK1 to HK3 and the cooling circuit,
additional consumers can be connected or controlled (e.g. air curtains,
swimming pools, etc.). The controller can receive the temperature
requests of these consumers via an Hx input and control the
corresponding pumps via a QX relay output. Various settings are available
for the consumer circuit. An appropriately defined Hx input on the device
or on an expansion module (program no. 5950, 5960 or 6046, 6054, 6062)
is required for use of the consumer circuit/swimming pool circuit. The input
can be defined as follows:
Consumer request VK1
Consumer request VK2
Consumer request VK1 10V
Consumer request VK2 10V
Release swi pool source heat
The pumps are connected at the appropriately defined multifunctional Qx
relay outputs. The consumer circuit pumps (Q15/Q18) are put into
operation if there is a heat or cooling demand at the corresponding input
or an excess temperature discharge is requested by the system. The
swimming pool circuit (Q19) is put into operation if there is a release at the
appropriate input and the swimming pool temperature (B13) is below the
"Setpoint source heating" (program no. 2056).
Flow temp setp cons request (1859, 1909, 1959)
Setting of the flow setpoint is done with this function, which is effective
during active request of the consumer circuit.
