Setpoints
Parameter in LDSWin * Description Value range Default value
Details see Visualisation in LDSWin - HT / LT / Power Signal Setpoints
External power signal
Button for switching between external power
signal and internal calculation.
EXT: external power signal.
INT: Calculation of the internal power
signal based on the setpoint and the flow
and return temperatures.
ON / OFF ON
HT P calculated over buffer
Button for selection of the control variable for the
return setpoint.
RL: the return temperature sensor is
used for the power signal calculation.
Buffer: a buffer temperature is used for
the power signal calculation. See also
next line.
RL / Buffer RL
Buffer temp. upper/lower
Button for selection of the buffer temperature
which should be used as the control variable.
UPPER: the upper buffer temperature
sensor is used for the power calculation
LOWER: the lower buffer temperature
sensor is used for the power calculation
UPPER / LOWER UPPER

Spread Spread between flow and return temperatures.
The pump adjusts its speed to this value.
2..70 K 7 K
Pump min
Minimum speed of the pump 0..100 % 20 %
Pump max Maximum speed of the pump 0..100 % 100%
max VL temp.
Maximum flow temperature
Note: The maximum flow temperature should be
at least 5 K greater than the flow temperature
setpoint.
Approaching below 5 Kelvin results in
throttling of the internal power signal HT.
Exceeding this limit causes the hot gas
valve to close.
0..80 °C 70 °C
max RL temp.
Maximum return temperature
Note: The maximum return temperature should
be at least 5 K greater than the return
temperature setpoint.
Approaching below 5 Kelvin results in
throttling of the internal power signal HT.
Exceeding this limit causes the hot gas
valve to close.
0..80 °C 55 °C
HT plate active
Button for deactivating the HT heat exchanger.
OFF: heat recovery is deactivated.
(pump off, hot gas valve closed)
ON: means heat recovery is activated.
The difference to the "HT present"
button is that the heat recovery can be
deactivated, but all monitoring
functions and the visualisation are
active.
YES / NO YES
