Select the appropriate menu option to determine the room sensor back-up mode. The back-up mode is used in the event
that the A2 room sensor fails or is disconnected. The following options are available:
•
NONE has no back-up mode of control should the A2 room sensor fail.
•
ROOM SENSOR option is only available if the control mode is set to NETWORK.
•
RETURN AIR BACKUP will default to return air sensor RT16 (should the A2 room sensor fail). The M3 Unit Controller
will switch over and operate based on the temperature from the return air sensor. RT16 is standard on all units; therefore
M3 Unit Controller Room Sensor System Mode 3 is the recommended backup mode when units are setup in the room
sensor mode.
•
THERMOSTAT will default to a local thermostat if one is installed (should the A2 room sensor fail). The M3 Unit
Controller will switch over and operate based on the signals from the room thermostat.
NOTE - The RT16 has a lower resolution than the A2 room sensor and should only be used as back-up.
