o Const ΔP/T, negative relation P/T, using
external temp. sensor
According to what described in par. 6.1.1, the
necessary correspondent settings are:
- 0x0030 - Temperature Control Mode = 1
- 0x0031
– Absolute Temperature Setpoint =
desired value
- 0x0033 – Temperature Probe = 1
- 0x0034 – Temperature Slope = 1
- Control Mode = Constant Pressure (settable
via User Interface)
- Constant Pressure Setpoint = desired value
6.1.2.4 Proportional pressure depending on
water temperature [Prop
ΔP/T]
In this control mode the drive alters the proportional
pressure set-point the pump has to maintain,
depending on the measured fluid temperature
Referring to
Figure 3

Tmin = 20

C

Tmax = Absolute Temperature Setpoint (par.
0x0031)

Hsmin = 30% of Hsmax

Hsmax = Proportional pressure set-point
(settable via User Interface, see par. 4.3.3.2)
According to what already described in par. 6.1.2.3,
even the Prop
ΔP/T control mode can be evidently
deployed in the subsequent possible application

6.1.3 Water Temperature dependent
Control Modes – Circulator Control
Panel
In order to configure the desired Temperature-
dependent control mode using Circulator Control
Panel, refer to the Advanced Tab
6.1.3.1 Advanced Tab
Collects two subset of parameters:

The subset used for advanced settings, as
described in this technical sheet at par. 8.2.1.2

The subset used for twin pump settings, as
described in this technical sheet at par. 8.2.1.3
