Service parameter(s) 174-198
174 Motor protection
Circuit Setting range
I OFF / 10 ... 59 min.
Prevents the controller from unstable temperature control (and
resulting actuator oscillations). This can occur when there is
no DHW tapping, i.e. when the load is only due to the DHW
circulation, or when the heating demand in the heating circuit
is very low. The motor protection increases the lifetime of all
involved components.
OFF: Motor protection is not activated.
10 ... 59:
Motor protection is activated after the set
activation delay.
A high value should be used for DHW
installations with many consumers.
196 Service pin - LON
Circuit Setting range
I ON / OFF
This setting is only used in connection with LON communication
(see the documentation for the used communication unit).
197 LON reset
Circuit Setting range
I ON / OFF
This setting is only used in connection with LON communication
(see the documentation for the used communication unit).
198 Daylight saving time changeover
Circuit Setting range
I ON / OFF
Choose whether you want the change to summer / winter time to
be automatic or manual.
ON: The controller's built-in clock automatically
changes + / - one hour on the standardized
days for daylight saving time changeover
for Central Europe.
OFF: You change manually between summer and
winter time by setting the clock backward
or forward.

199 Master / slave address
Circuit Setting range
I 0 ... 9, 15
The setting is relevant when more controllers are working in the
same ECL Comfort system (connected via the system device bus
(ECL Comfort BUS)).
0:
The slave receives information about the
outdoor temperature (S1), system time, and
signal for DHW demand in the master.
1 ... 9: The slave receives information about the
outdoor temperature (S1), system time, and
signal for DHW demand in the master.
The slave sends information about the
desired flow temperature to the master.
15:
The controller is master. The master sends
information about the outdoor temperature
(S1), system time, and the DHW demand
signal.
The master receives the desired flow
temperature information from the slaves
with addresses 1 ... 9.
The bus is active and connected ECAs are
powered.
The ECL Comfort controllers can be connected via the bus to
perform a larger system. The controller, which is physically
connected with the outdoor temperature sensor, is the
master of the entire system and automatically gets the
address 15.
Each slave must be configured with its own address (1 ... 9).
However, more slaves can have the address 0 if they only have
to receive information about outdoor temperature, system
time, and signal for DHW demand in the master.
