Consumer Circuits/Swimming Pool Circuit - Potterton Paramount four Installation Manual

9 Settings
92 Paramount four 30 – 115 kW
Note
If the colder storage tank temperature rises to above the legionella
function setpoint -1 K, the legionella function setpoint is consid­
ered as met and the timer starts running. If the storage tank tem­
perature drops by more than the switching difference +2K below
the required legionella function setpoint, the duration has to be
met again. If no duration has been set, the legionella function is
met immediately when the legionella function setpoint is reached.
Legionella funct circ pump (1647)
On: The circulation pump will be switched on in case of active legionella
function.
Warning
When legionella function is active, there is a risk of scalding at the
draw-off points.
Circulating pump release (1660)
Time central heating CH3: The circulating pump is released subject to
time program 3 (see prog. no. 540 to 556).
Hot water release: The circulating pump is released when DHW heating
is released.
Time hot water: The circulating pump is released subject to time pro­
gram 4.
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 a sensor is placed in the drinking water distribution pipe, it monitors reg­
ulation and actual value during the legionella function. The setpoint set
must be observed on the sensor during the dwell time set (prog.no. 1646).
The maximum setting of the circulation value is limited by the nominal set­
point.
Optg mode changeover (1680)
Using external switching above the entrance H1 it can be selected into
which operating mode is switched into.
Off: The function is switched off.

9.2.8 Consumer circuits/Swimming pool circuit

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.
Hot water 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 de­
termines whether the system pump goes into operation when a heat de­
mand is submitted.
No: The heating circuit is supplied from the boiler.
Yes: The heating circuit can be supplied from the buffer storage tank.
