ALARM RECOVERY
Probe alarms "P1", "P2", "P3" and "P4" start some seconds after the fault in the related probe; they
automatically stop some seconds after the probe restarts normal operation. Check connections before
replacing the probe. Temperature alarms "HA", "LA", "H2" and "L2" automatically stop as soon as the
temperature returns to normal values. It is possible to reset the "EE" alarm by pressing any button.
The alarms "EA", "CA" and "dA" will automatically stop as soon as the digital input is disabled.
The internal buzzer can be muted by pressing any key if parameter tbA=Y.

Unauthorized repairs, changes or modifications could result in permanent damage to the equipment and void
your warranty and your authority to operate this device under Part 15 of the FCC Rules.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct the interference at
his own expense.
20.1.4
THE XR70CHC IS COMPLIANT TO RSS 102
This device complies with Industry Canada RSS-210. Operation is subject to the following two conditions: (1)
this device may not cause interference, and (2) this device must accept any interference, including
interference that may cause undesired operation of the device.
20.1.5
CET XR70CHC INSTRUMENT REPOND AUX NORMES RSS 102
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio RSS-210.
L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est

BLUETOOTH COMMUNICATION
The controller implements a Bluetooth 4.2 communication module. This gives
the possibility to communicate with external devices (for example with a mobile
APP able to recognize and decode the device). All controllers use a unique
MAC-ADDRESS, which is used both for identification and communication. The
communication range is about 5 m (worst case, indoor coverage in presence of
obstacles). Over this distance it is possible to suffer interruptions in the
communication or quality degradation of the communication. A 6-digit pairing
secure code can be required for connection. Please follow the Emerson
Connected APP instruction for more information.
22.1
FIRST INSTALLATION
After installation, it will be possible to manage the controller by using the Emerson Connected APP. Il will be
required to:
-
Install the Emerson Connected APP on your mobile device (smartphone or tablet)
-
Create a new user account before using the APP
The owner is the only account that can:
-
Manage the controller via Bluetooth
-
Extend rights of access to a specific appliance also to other users
A Cloud portal will be used for:
-
Extend rights of access to a specific appliance also to other users
-
Select the permission level for any new user
The link for opening the Cloud webpage is on the left side menu of the mobile APP (slide right the screen of
the APP when on the Device List page and follow the "Cloud management" link. Please note that the login and
password for the Cloud webpage are the same of the mobile APP.
22.2
RESET TO FACTORY DEFAULT
In case a factory reset is required, please follow these operations:
-
Access to the Cloud webpage and select the appliance you want to reset (search for name
and/or MAC-ADDRESS)
-
Click on the "DELETE" link, the appliance will be removed from the list of owned appliances
-
Go to the device controller (with the same MAC-ADDRESS)
-
Enter the programming mode
-
Go to the "bLE" menu
-
Select the par. rPS (reset device ownership)
-
Select "Y" and confirm with SET button
-
Select the par. rLi (reset device whitelist)
-
Select "Y" and confirm with SET button
-
Exit from the programming menu
-
Logout and login from the mobile APP
After this, the controller will be reset to factory default configuration and it will be ready for a new association.
