Select a relay then set its status as follows:
The relay is assigned to the output;
- - -
The relay is not assigned to the output;

in timer mode (available on fan stage out-
puts only).

• Proceed in similar fashion to assign relays to
each output in use:
• Fan stages 2-12:
Fan stages can either activate regular on/off re-
lays and/or timer-based relays. When a timer-
based relay is assigned to a fan stage, the relay
runs in timer mode when the fan stage is ac-
tive. This is useful to operate misting units for
instance. To use timer-based relays, set the re-
lay status to "TMR" (see example above).
• Tunnel 1-2 / Vent door (inlet) 1-2 /
Natural ventilation curtains 1-2:
When actuators are connected to these relays,
their open and close relays can never be acti-
vated at the same time.
• Feeding output:
Feeder relays are used to stop feeders when a
feeder run time alarm occurs. These normally
closed relays open when the alarm condition is
detected.
Accessible if the feeder alarm condition is enabled (sec-
tion 11.3.
• 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. Refer
to the natural ventilation section of this manual
to get further information about this feature.
• Heating stages 1-4 & Hi Fire stages 1-4 (opt.);
• Misting output;
• Cool cell output;
• Clock outputs 1-2;
• On/Off Light outputs.
A template is available at the end of
this manual to write down the function
of each relay.
