FUNCTIONS
AUTOMATIC CABIN PRESSURE
The INPRESS TS is an intelligent pressuriser controller that monitors
the pressure difference from inside to outside of the cabin. It controls
the speed of the motor to maintain a set pressure difference.
LOW PRESSURE ALARM
If the cabin pressure falls below the alarm setpoint, INPRESS TS will
wait the designated delay time before alarming user.
The alarm will sound, and LOW-PRESSURE WARNING will flash on
screen in red lettering. Press the ALARM button to mute the alarm.
At the same time as this alert is sounding, the fan power will increase
to maximum to keep operator as safe as possible.
ALARM DELAY

pressure and sounding the delay. This gives allowances in time for
small changes like opening window briefly. The amount of delay can
be changed in settings.
SERVICE REMINDERS
The INPRESS TS has automatic reminders for servicing of filter system.
The default is 500 runtime hours, but can be altered in settings.
