Operating Guide
P318, in general
Up to two Remote Control Units, ECA 30 / 31, can be connected to
one ECL controller in order to control the ECL controller remotely.
Additional ECL Comfort controllers can be connected via the ECL
485 bus in order to utilize common outdoor temperature signal,
time and date signals. The ECL Controllers in the ECL 485 bus
system can work as master and slaves. The application P318 can
work alone or as a slave.
Heat-meters:
Up to 5 heat-meters can be connected to the M-bus terminals.
Data can be transferred to the SCADA system via Modbus and TCP /
IP to the ECL Portal.
The P318 application has event indications for
• Charging temperature (P318.1)
• Tank (buffer) temperature (P318.1)
• DHW flow temperature (P310.10)
• Supply temperature
• Anti-bacteria
Typically, an event is registered if a set temperature condition is
not accepted. The events can be prioritized to be indicated as
information or an alarm.
The alarm A1 (= relay 6) can be activated if:
• an event occurs
• a temperature sensor or its connection disconnects / short
circuits. (See: Common controller settings > System > Raw
