DIP-SWITCH 2: Periodic activation of auxiliary output:
If the auxiliary output always remains off, it is
switched on for 1 minute every 2 days to prevent the
pump from being damaged due to inactivity.
Function deactivated.
The "periodic activation of auxiliary output" option is useful
if the system includes a circulation pump that could undergo
damage if left inactive for long periods of time. When this
option is enabled, the auxiliary output will be switched on for
1 minute every 2 days. The output will be switched on at the
same time as the actuators if the periodic activation function
is also enabled for the actuator outputs.
DIP-SWITCH 3: Share auxiliary output:
The auxiliary output will be switched on/off according
to the status of the channels of all modules connected
in a chain.
The auxiliary output will be switched on/off according
to the status of the channels present on the same
module.
If the "share auxiliary output" option is enabled, the relay will
be controlled according to the status of the channels of all
modules connected in cascade to one another. If the option
is disabled, the auxiliary output relay will be switched on or
off depending solely on the status of the outputs present on
the module to which the relay itself belongs.
DIP-SWITCH 4: Heating/Cooling selection via external
input:
The Heating/Cooling status is determined by
theexternal Heating/Cooling input.
The Heating/Cooling status is determined by the
thermostat transmitter.
When the "Heating/Cooling selection via external input"
option is enabled, the external Heating/Cooling contact will
determine the operating mode for all thermostat-controlled
channels of the module. See the paragraph on "External
Heating/Cooling input" for further information.
If the system you are installing does not require any
particular options to be enabled, it is sufficient to leave all
DIP-switches in the "0" ()position.
Heating/Cooling selection
The relay module is factory configured (DIP-switch 4 down)
so that that the Heating/Cooling status of each channel will
be determined by the setting of the associated thermostat
transmitter.
However, if a chronostat is present in the system, it will
override the thermostat settings and impose its own Heating/
Cooling status on all thermostat-controlled channels,
including those of other modules connected in cascade to the
same active antenna.
This makes it possible to change over the mode selection
easily by means of a single device (chronostat) without
having to adjust every thermostat individually.
If there is more than one chronostat in the system, the one
controlling the lowest channel (in the module closest to the
antenna, in the event of a number of cascade-connected
modules) will override the others in determining the Heating/
Cooling status.
The Heating/Cooling status of a chronostat can never be
changed via the relay module: it must always be adjusted
manually. The options permitting a global Heating/Cooling
changeover apply only for the channels controlled by
thermostats.
If the relay module is configured so that the Heating/Cooling
status is determined by an external input (DIP-switch 4 up),
the thermostat-controlled channels will take on the status
defined by the external contact. However, the module cannot
change the Heating/Cooling status of any channels controlled
by chronostats.
In cases where a chronostat is present in the system, it is
not convenient to use the "Heating/Cooling selection via
external input" option since you can change the Heating/
Cooling setting of all thermostat-controlled channels simply
