Thermostat Function - Cosmo Multi 3 Montage- Und Bedienungsanleitung

8. ARRANGEMENT
In addition to the pre-defined optional functions, function blocks consisting of thermostat func-
tions, timer, differential, reference output and flow rate functions are available. With the help of
these function blocks, further components and functions respectively can be controlled.
To each function block, sensors and outputs available can be allocated.
Within a function block the functions are interconnected (AND gate). This means that the switch-
ing conditions of all the activated functions have to be fulfilled for switching the allocated output.
As soon as one condition is not fulfilled, the output will switch off.

Thermostat function

The switching condition for the thermostat function is considered fulfilled when the adjusted
switch-on temperature (Th-(x) on) is reached.
The switching condition for the thermostat function is considered unfulfilled when the adjusted
switch-off temperature (Th-(x) off) is reached.
Allocate the reference sensor in the Sensor channel.
Adjust the maximum temperature limitation with (Th-(x) off) > (Th-(x) on) and the minimum tem-
perature limitation with (Th-(x) on) > (Th-(x) off). The temperatures cannot be set to an identical
value.
DT function
The switching condition for the DT function is considered fulfilled when the adjusted switch-on
temperature (DTOn) is reached.
The switching condition for the DT function is no longer considered fulfilled when the adjusted
switch-off temperature (DTOff) is reached.
The DT function is equipped with a speed control function. A set temperature difference and a
minimum speed can be adjusted. The non-adjustable rise value is 2 K.
Reference output
Up to 5 reference outputs can be selected. Whether the reference outputs are to be switched
in series (AND), in parallel (OR), in series + inverted (NAND) or in parallel + inverted (NOR) can be
adjusted in the Mode channel.
OR mode
If at least one of the reference outputs is switched on, the switching condition for the refer-
ence output function is considered fulfilled.
If none of the reference outputs is switched on, the switching condition for the reference
output function is considered unfulfilled.
NOR mode
If none of the reference outputs is switched on, the switching condition for the reference
output function is considered fulfilled.
If at least one of the reference outputs is switched on, the switching condition for the refer-
ence output function is considered unfulfilled.
AND mode
If all reference outputs are switched on, the switching condition for the reference output
function is considered fulfilled.
If at least one of the reference outputs is switched off, the switching condition for the refer-
ence output function is considered unfulfilled.
NAND mode
If at least one of the reference outputs is switched off, the switching condition for the refer-
ence output function is considered fulfilled.
If all reference outputs are switched on, the switching condition for the reference output
function is considered unfulfilled.
Flow rate
If the adjusted switch-on flow rate is exceeded, the switching condition for the flow rate function
is considered fulfilled.
If the flow rate falls below the adjusted switch-off value, the condition for the flow rate function
is no longer considered fulfilled.
The flow rate sensor for this function can be selected.
