Formula for Mean Factors A0, r8, r9
Temperature calculation by the following formula:
Temperature = Airin * (1 - Mean Factor / 100) + Airout * Mean Factor / 100 Examples:
Mean factor = 0 Temperature = Air in Mean factor = 100 Temperature = Air out
Mean factor = 50 Temperature = Average between
Alarm Codes

AF Valve Status
Valve closed due to compressor safety loop active
Ao Superheat, emergency operation
Sensor(s) failure
Ar No refrigerant flow detected
No refrigerant flow was detected
Au Valve open 100% for more than 10 minutes
dt Forced defrost termination (time or temperature) Ft Forced fan startup (time or temperature)
Messages
---No data to display
The display will show an
In Reset to default values activated
The display will show an “In” when the factory default configuration data set is initialized.
Id Wink request received
The display will show a flashing “Id” when the wink request was received. The flashing “Id” will be shown on the display until the service button will be pressed, or a 30 min delay timer will expire or a second wink request is received. This function is action only when using SNMP protocol
OF Node is offline
The node is offline and no application is running. This is the result of a network management command and will happen for example during node installation.

No special software or hardware is required.
Connect the
Open the Internet browser program on the computer and enter the default TCP/IP address of the controller into the address line of the Internet browser: 192.168.1.101 or the dynamic address from the DHCP server. Refer to the TCP/IP Controller- Readme file if a specific port is required.
After a few moments, the default monitoring page should be displayed. If the browser does not open the default page or display active data, the user should check the Internet browser “Option” configuration. Refer to the TCP/IP Controller- Readme file.
The Monitoring and Alarm WebPages are read only and therefore it is not necessary to enter a username or password. A username and password will be requested upon the initial request to any of the other WebPages. The factory default settings are:
Username: EmersonIDPassword: 12
The default settings may be modified in the Display configuration page.
Press the tabs at the top of the Monitoring page with a left click of the mouse button to enter the respective Webpage.
The parameters will be visualised in real text together with the program code as defined in the parameter list below.
After the parameters have been modified, the complete list of settings can be saved to the memory of the computer and used later to upload into another controller. This can save a considerable amount of time when using multiple controllers and over a period of time, a library can be created containing the parameter lists for equipment for different applications.
It is also possible to display live graphical data from the controller. In addition, a permanent 30 days log file containing the control temperature at 15 minutes intervals is stored in the
