Frost protection for the ATA unit

A minimum room temperature can be set under "Frost protection". As soon as the room temperature falls below this val-
ue, the system automatically heats the room to this temperature. This helps to protect the room and structure from dam-
age that could be caused by low temperatures.
ENABLE
Select "On" to activate frost protection. If the room temperature then falls below the minimum temperature level, the sys-
tem automatically enters heating mode to maintain the minimum temperature. Select "Off" to deactivate frost protection.
MINIMUM AND MAXIMUM TEMPERATURE
When frost protection is active, use "Minimum temperature" and "Maximum temperature" to control the desired minimum
temperature as well as a maximum temperature at which the frost protection process is completed. Select "Continue" to
complete the frost protection settings.
MENU STRUCTURE
As soon as frost protection has been activated and set, select the systems in the MELCloud for which frost protection is
to be activated. To activate frost protection for these systems, select "Continue". Please keep in mind that in MELCloud
it is not possible to select different frost protection settings for different systems. The set frost protection applies to all
selected systems.
NOTE!
►This feature works properly only when the systems are connected and communicating with the
MELCloud servers. If the internet connection is disrupted during this time, the systems may not be
able to be controlled until the connection is re-established.
