Atmospheric temperature sensor
An atmospheric temperature sensor can continue to be connected to the terminals 55 and 56. This sensor is
used to control the automatic frost protection feature. Moreover, this sensor can be used when operating a
swimming pool air heat pump to shut the heat pump down if the air temperature is too low. Either a water
temperature sensor (Item. no. 310.000.0001 (1,5m) or 310.000.0005 (5m), rsp.) or a solar sensor (item no.
310.000.0033) can be used for this purpose.
Connecting to the computer network
Connection to the Internet is carried out by the communication server. The WATERFRIEND MRD-3 is
connected using a standard Ethernet patch cable into the network wall outlet, the powerline adapter, the
wireless LAN access point or other suitable facilities.
After the EUROMATIK was connected to an active network outlet, the power supply can be turned on. The
web server in EUROMATIK now searches autonomously for the communication server and logs on to the
database.
If the "OSF" icon in the monitor is visible (see chart), the EUROMATIK has logged on to the
communication server.
