Extra sensors


Extra sensors are used for supervision of temperatures that are not related to any control functions.

Access can handle up to 5 extra sensors. Each of these temperature signals can be supplemented with alarms for high and low limit.

Additional alarm is for monitoring state of the sensor (if it is connected and working properly
