A timer is also available for the extended running mode. By default, the timer value for the function is set to 0 minutes. This means that the unit will go
in extended running once the input is triggered and remain in extended running until the input goes from on to off.
Depending on the source used to trigger the input and/or the nature of the application, an extended running timer can be configured. The timer will
start after the extended running input goes from on to off. For example, if the extended running input is triggered, the unit will go into normal speed
(1/1) and remain in that mode as long as the input is active. Once the input goes from on to off, the unit will remain in extended running for the
duration set for the timer. To configure the extended running timer follow the steps below.

The fire alarm digital input can be used to connect the unit to fire alarms or the building management system (BMS) in order to stop the unit in case of
a fire. If the fire alarm input is triggered the unit will initiate the stop sequence and stop the ventilation. A controller alarm will also appear on the unit
external display to indicate that the fire alarm input is active.
Fire alarm
The fire alarm(s) or BMS output has to be wired to terminals TB3 75 & 4, DI5 & +24VDC respectively (see wiring diagram). Remember to
cut the power to the unit at the all pole circuit breaker before performing any electrical work.
Check if the unit’s operation, as explained above in case of a fire, conforms to the local building code or the authorities having jurisdiction in
your area.

A means of triggering the input will be required (field supplied and specified) and wired to terminals TB3 74 & 4, DI4 & +24VDC respectively
(see wiring diagram). Remember to cut the power to the unit at the all pole circuit breaker before performing any electrical work. The
Extended running digital input has precedence over the recirculation digital input and the normal, reduced and recirculation schedules. If any
stop condition is met, the unit will stop even if the extended running input is active.
