Description
1
YES
NO
Closed contact (request dehumidification) activates the first stage of regeneration resistors.
Open contact deactivates the first stage of regeneration resistors, while the ventilation continues to operate.
If the parameter FA01 = OFF, the contact is open, turns off the first stage of regeneration resistors, and will also stop the ventilation
(the fan of reactivation and the gear motor continue to operate for a period, depending on the configuration, to perform the post-
cooling of the reactivation)
2
YES
YES
Closed contact (request dehumidification) activates the first (priority step1) and the second (step2) stage of reactivation resistors.
Open contact deactivates the first (step1) and the second (step2) stage of reactivation resistors, while ventilation continues to operate.
If the parameter FA01 = OFF, with the open contact of the first stage (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.
3
YES
YES
Closed contact (dehumidification request) activates the first (step 1 priority) and the second and third (step 2) stage of reactivation
resistors.
Open contact disables the first (step 1) and the second and third (step 2) stage of the reactivation resistors, while the ventilation
continues
to
operate.
If the parameter FA01 = OFF, with the open contact of the first stage (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.
4
YES
YES
Closed contact (request dehumidification): the first step activates the 50% power (step1 priority), the second step activates the 100%
power (step 2) of the resistances of reactivation.
The open contact deactivates the power control of the resistances of reactivation, while the ventilation continues to operate.
If the parameter FA01 = OFF, with the open contact of the first step (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor, continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.
5
YES
YES
Closed contact (request dehumidification): the first step places 50% the steam valve (step1 priority), the second step positiones at
100% the steam valve (step 2).
Open contact of the second step (step 2) positiones at 50% the steam valve, with both the open contacts of the steps the steam valve is
positioned in the fully closed is 0%, while the fan continues to operate.
If the parameter FA01 = OFF, with the open contact of the first step (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor, continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.
6
YES
YES
Closed contact (request dehumidification): the first step turns on the burner and activates the required minimum flame (step1 priority),
the second step activates the required maximum flame goes out and the demand for minimum flame (step 2). With the open contact
of the second step (step 2) you have the required minimum flame, with both open contacts of the steps you have shut off the burner,
while the ventilation keeps running.
If the parameter FA01 = OFF, with the open contact of the first step (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor, continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.
7
YES
YES
Contact closed (request dehumidification): the first step turns on the burner and activates the request command minimum flame
(step1 priority), the second step activates the request command maximum flame (step 2). With the open contact of the second step
(step 2) you have the required minimum flame, with both open contacts of the steps you have shut off the burner, while the ventilation
keeps running.
If the parameter FA01 = OFF, with the open contact of the first step (step1), it will also stop the ventilation (the fan of reactivation and
the gear motor, continue to operate for a period, depending on the configuration, to make the post-cooling of reactivation). If we only
use one control/command contact, both the control steps (step 1 and step 2)must be closed in this configuration.

YES
NO
Contact closed (dehumidification request), activates the output proportional to 100%, with the open contact disables the output
proportional to 0%, while the ventilation continues to function.
If the parameter FA01 = OFF, the contact is open, it deactivates the output proportional to 0%, and will also stop the ventilation (fan
regeneration and the motor will continue operating for a period, depending on the configuration, for perform post-cooling of the
regeneration).

YES
Contact closed (request dehumidification), activates the output proportional to the 100% and the first and the second and third stage
of regeneration resistors according to the configuration, the contact is open it deactivates the output proportional to 0% the first, the
second and third stage of regeneration resistors, while the ventilation continues to run.
If the parameter FA01 = OFF, with the open contact of the first step (step1), it will also stop the ventilation (fan of regeneration and the
gearmotor, continue to operate for a period, depending on the configuration, to make the post-cooling of regeneration). If it takes
action only one contact control / command, in this configuration they must be closed both control steps (step 1 and step 2).
