Name
-
Default names or give names individually.
Connection -
Name of the real hardware connection on Heatmaster.
Nominal resistance at 25°C
-
This property shows the nominal resistance (Rn) at the nominal
Temperature (Tn) of the NTC
-
Temperature sensors
.
(see further Appendix 1)
Constant “b“ -
This is the so called beta value, which describes the reaction to temperature
changes of the NTC-resistor according to the sensitivity. This value is also to be referred in the data
descriptions of the manufacturer. (see Appendix 1)
Sensor Ref. -
You can enter here a reference sensor for calculating delta-t value. This value
displays the temperature difference between these sensor values and can be given only once.
Example
: You can calculate the difference value for example between PC-casing inside and room
temperature, water temperature and air temperature (e.g. radiator) etc. (condition: sensors are
placed in relevant places).
Delta
–
Shows the calculated difference value (delta t)
10 Fans / Pumps device icon
You can distribute / allocate up to four fans in four control-loops or up to maximum four fans in one
control-loop from the Library (5). Fans and pumps use same icons, as they have the same function
(transport of cooling medium) and are operated and controlled by the same Heatmaster hardware
components. You can also use more than four fans. See the topic Connection Definitions 6,
fans/pumps connections.
Device properties:
Revolution -
Shows the actual revolution of the Fan in RPM.
Achieved RPM -
Shows the highest measured RPM(
R
ounds
P
er
M
inute) value (Peak-value).
Serves as reference and can be used for scaling.
Actual PWM (%) -
Shows the actual value in a percentage. This value can be changed manually, if
the control-loop is deactivated. PWM (
P

M
odulation) is simply a process to control
analogue devices digitally (e.g. Motor of a fan). Thereby the current will be given in temporal
intervals through modulation to the fan motor, where the current does not flow between the pulses.
The fan motor operates then at sufficient pulses in a certain time with 100% current, where the
motor achieves it maximum performance. As it is not possible to convert this from linear to analogue
operating voltage, this value is given in a percentage.
Maximum PWM (%)
-
This property specifies the maximum PWM value for the fan. With inserting
of a value under 100% you can limit the maximum performance/maximum revolution of the fan, for
example to minimize the loudness. Thereby the maximum capacity of the fan drops, which limits the
cooling performance again. This value displays the above range limit.
Unregulated running value PWM (%) -
Shows the set up running value for the initial stage, where
the Heatmaster hardware does not assume the control yet. This value is regularly set up at 100.
Starting threshold PWM (%) -
This is the lowest possible value, at which the fan barely starts.
This value can be changed/ optimized manually if needed, so that the fan definitely runs. Thereafter
it reaches the default value.
Lowest Running value PWM (%) -
This property specifies the lowest possible value in operation
where rather lower values stop the function of the fan.
Minimum PWM (%) -
Shows the minimum set PWM value. This value displays the below range
limit.
