Min Vent. Relay Assignment
Set the status of each relay: select “2. “ if
the relay is used in minimum ventilation or
select “- - -” if it is not.
Relays 21-36 correspond to relays 1-16
of the external relay panel.
4.8.3. Variable Output Assignment
Two variable outputs can be used to provide
variable-speed ventilation. If they are used,
assign each of them to proper fan stages.

Variable 2 Var
Fan Stage 2 Variable 1 On
Variable 2 Off
Set the output status separately for each 2.
fan stage in use:
Var — The variable fan output is assigned to
the fan stage and operates in variable mode:
when the stage starts, the variable fan starts
running at its minimum intensity. The fan
intensity gradually increases as the room
temperature increases.
On — The variable fan output is assigned to
the fan stage and operates in on/off mode:
the fan runs at 100% when the fan stage is
on and stops when the stage is off.
Off — The variable output is not assigned.
If the last fan stage uses a variable
output, the output must use the on/off
operating mode. Do not set the operat-
ing mode of the last fan stage to the
variable mode.
Tunnel 1-2 / inlet 1-2 / natural curtains 1-2 —
Relays 7-8 and relays 15-20 have specially
been designed for the connection of actua-
tors. When actuators are connected to these
relays, their open and close relays can never
be activated at the same time.
Feeding output — Feeder relays are used to
stop fee ders whe n a fee der run time alarm oc -
curs. These normally closed relays open when
the alarm condition is detected. *Accessible if
the feeder alarm condition is enabled (sec. 12.3).
Backup relay — The backup relay box relay is
a normally closed relay which opens in case
of a power failure.
Shutoff fans in natural ventilation — It is
possible to shutoff some fan output when
the controller enters in natural ventilation
(on/off fans and variable fans). Refer to the
natural ventilation section of this manual to
get further information about this feature.

4.8.2. Assigning Min. Vent. Relays
This procedure shows how to assign on/off
relays to minimum ventilation cycles. Cho-
sen relays will switch during the “On Time”
portion of minimum ventilation cycles. Refer
to section 6.1 for further information about
minimum ventilation cycles.
