.
When
“
switching
”
over via a digital input, the device works with the opposite direction of
rotation than the one set in Motor Setup.
If the rotary direction is reversed with an available modulation, it is initially reduced to
“
0
”
(disconnected) and subsequently increased back to the default value.
15D
Bypass temperature management (operation at max. speed)
To make the ECblue as durable as possible, the devices have active temperature
management. The modulation is reduced when internal temperature limits are ex-
ceeded.
In ventilation systems in which the fan has to continue operating at maximum speed
despite overtemperature, temperature management can be deactivated using a digital
input. At the same time, the fan is operated at maximum speed regardless of the
speci
fi
ed speed for regular operation.
The function is active at the digital input when the contact is open (in factory setting
|
D1/E1 Inverting
|
= OFF), so that the maximum fan speed is still possible even when
the line to the digital input is interrupted.
Attention!
•
This function is implemented by switching to
“
Set Intern3
”
. A setting of 100 % (=
rated speed) of
“
Set Intern3
”
is a prerequisite for operation at maximum speed.
•
The device and its internal components are no longer protected against overtemper-
ature when this function is activated (this affects the life installation instructions
ECblue).
19D
Bypass temperature management (operation with variable speed)
This function differs from 15D due to operation at variable speed. When temperature
management is switched off by a digital input, speed setting by an external signal is still
possible. The speed set in
“
Set Intern3
”
is the maximum speed at 100 % setting signal
(limitation).

Networking via MODBUS
It is possible to network several devices with each other. The device uses the MODBUS-RTU as the
protocol for the RS-485 interface.
Bus Address
The device address is factory set to the highest available MODBUS address: 247.
Setting range MODBUS Address: 1 - 247.
