WATTrouter Mx - user manual
server is ignored. The default and recommended name is pool.ntp.org, which is a service that
automatically assigns the IP address of a particular time server, based on the load of individual time
servers and other criteria. You can use the "Test time server and get it's IP" button to verify the
functionality of the server.
Firmware up to version 1.5: The controller does not save the time server domain name and it only
appears in WATTconfig. Find the closest time server from available resources on the Internet, enter its
domain name and press the "Test Time Server and Find IP" button.

Time server address (IPv4) - time server IP address stored in the controller. Here changes were made
since firmware version 1.5:
Firmware since version 1.5: The IP address of the time server does not need to be set and detected,
just use a valid time server domain name. However, in case the IP of a time server cannot be found
from its name, an attempt will be made to contact the time server specified by this IP. Therefore, it is
possible to use this field as a backup solution to the specified domain name.
Firmware up to version 1.5: Set this IP either manually, or enter the time server domain name in the
Time server (hostname) box, then press the "Test Time Server and Find IP" button.

Use summer time - check this field if you want the controller to perform automatic switching between
summer and winter time. Based on EU recommendations only summertime is supported, which starts
at 2:00 CET on the last Sunday in March and ends at 3:00 CEST on the last Sunday in October. The
summertime information is used to automatically modify the current time as well as the calculated
sunrise time.

Time zone - specify the time zone based on your country. The default value uses Central European
time. This value is only used to modify the calculated sunrise time. Time zones outside of multiples of
full hours are not supported.

Test time server and get its IP - press to test the time server and determine its IP address. The IP
address is written to the controller when the configuration is next written. Since firmware version 1.5
there is no need to use this feature, IP is detected primarily from the specified domain name.

Synchronize time now! - press this button to instantly synchronize the time in the controller (without
requiring configuration writing). If the Synchronize date and time with the client check box is checked,
the time is set equal to PC time, otherwise the time server synchronization is performed (if properly
configured, otherwise nothing will be done).
CombiWATT settings:

CombiWATT delay time – specifies the time delay from the moment where PV-plant production is not
detected anymore (after sunset) until CombiWATT can become active. It is recommended to increase
the setting if you are frequently using electrical loads (other loads than those connected to the
controller), which consume entire surplus energy of the PV-plant for long time. In this case, the
controller cannot recognize that PV-plant production is not yet over.

Time to activate CombiWATT – it displays the remaining time before activation of the CombiWATT
mode. The value is equal to the "CombiWATT delay time" parameter, provided that some surplus
energy is still detected. If the value equals to zero and low tariff signal is detected at the same time,
the system activates the CombiWATT mode for corresponding outputs.

CombiWATT production limit – small amount of active production or surplus energy (single units or
tens of Watts) may be detected for facilities with significant capacity loads (blocking capacitors, UPS
stations, large number of switching sources, etc.), even though the inverter does not work. The cause
