9.2.8
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.
DHW charging priority (1874, 1924, 1974)
Setting as to whether domestic hot water charging takes priority over the
consumer circuit/swimming pool circuit or not.
Excess heat draw (1875, 1925, 1975)
If an excess temperature discharge is activated, the excess energy can be
discharged heat being drawn by the consumer circuits. This can be set
separately for each consumer circuit.
With buffer (1878, 1928, 1978)
This parameter establishes whether the heating circuit can be supplied by
a buffer or storage tank or only by a heat generator. The function also
determines whether the system pump goes into operation when a heat
demand is submitted.
No: The heating circuit is supplied from the boiler.
Yes: The heating circuit can be supplied from the buffer storage tank.
With prim contr/system pump (1880, 1930, 1980)
No: The consumer circuit is supplied without primary control unit/system
pump
Yes: The consumer circuit is supplied from the primary controller on/by
the system pump.
9.2.9
Swimming pool
The controller enables a swimming pool to be heated with solar energy or
via heat generators, each with a separately adjustable setpoint. For solar
heating, the priority of the swimming pool heating relative to the storage
tank charging can be set.
Setpoint solar heating (2055)
When solar energy is used, the swimming pool is heated to the setpoint
set here.
