The regulating mode is set from Page 2.0. It is possible to choose from 9 different modes:
1.
= Regulation with constant differential pressure
2.
= Regulation with constant curve with speed set from the display.
3.
= Regulation with constant curve with speed set by remote signal 0-10V.
4.
= Proportional differential pressure regulation.
5.
=
T constant regulation increasing mode
6.
= T constant regulation decreasing mode
7.
= T1 constant regulation increasing mode
8.
= T1 constant regulation decreasing mode
9.
= ∆T constant regulation
Page 2.0 displays the three icons which represent:
central icon = setting currently selected
right icon = next setting
left icon = previous setting
Page 3.0
The regulating set-point is set from Page 3.0.
Depending on the type of regulation chosen on the previous page, the set-point to be set will be a head
(
Hs
), a frequency (
Fs
), a temperature (
Ts
) or a difference in temperature (
dTs
).
Page 5.0
Page 5.0 is displayed in all pressure regulating modes and allows the setting of “auto” or “economy”
operating mode.
“Auto” mode disables the reading of the status of digital input I2 and in fact the system always activates
the set-point set by the user.
“Economy” mode enables the reading of the status of digital input I2. When input I2 is energised the
system activates a percentage reduction of the set-point set by the user (Page 6.0).
For the connection of the inputs see par. 5.5.1
Page 6.0
Page 6.0 is displayed if “economy” mode has been chosen on page 5.0 and allows setting of the
percentage reduction value of the set-point.
This reduction will be carried out if digital input I2 is energised.
