12. BOOST FUNCTION (Only available in CAV and COP modes)

By closing an external digital contact, it is possible to force the fan operation at normal

speed for a setted time. (30 mins. by default)

The speed corresponds to the normal pressure setpoint set in COP mode or to the normal

airﬂ ow speciﬁ ed in CAV mode.

The Boost function can be activated, only when the unit is not within a timer period of

normal speed. In this case, even if boost is executed, the timer will start to count once the

period of normal speed is ﬁ nished (the boost order gets delayed).

This function is not availble in VAV mode.

The activation of the Boost function has to be activated with an external switch. To activate,

it is necessary to close the contact between +C and BT for 3” and then open it.

Once the Boost function has been activated, to cancel the forced normal speed period, it is

necessary to do a Remote ON-OFF (see next point).

13. REMOTE STOP-START

It is possible to start-stop the unit by means of an external digital contact (see electric

diagrams). The contact closure between +C and ES, will produce the unit stop.

When the equipment is stopped remotely the control hand terminal displays an

alarm message. Although this is not a real anomaly, this way it is intended to warn

about the possibility that the unit will be start up from remote at any time.

When Access to alarm menú it is shown the message “External Switch”.
