Programing Tasks Part; Temperature Control - fischertechnik ROBO STARTER Begleitheft

Before you move on to the second part of the programing tasks, you should go back to the ROBO Pro
handbook.
Work through chapter 5 carefully in the handbook. Switch to level 3 in ROBO Pro.
The programing tasks are slowly becoming more demanding. We will use analog inputs, operating
elements, operators and variables.
However, if you read the ROBO Pro handbook attentively, you will find it easier
to use later.
At home where you live, a new air
conditioning system was installed. Of
course, you immediately asked the
installer how the temperature control works.
He was happy to explain to you that a temperature
sensor continually measures the temperature. As soon as a
maximum value is exceeded, the air conditioning is turned on.
However, on the other hand, if the temperature is below the minimum value, the air conditioning is
turned off and the heating is turned on. Now, using the "temperature control" model, you also want to
try to program such a control circuit. But first, build the model.
Ta s k :
The heating is simulated by the lens tip bulb, M2.
The blower on output, M1, serves as the "cooling unit."
To measure the temperature, we will use the NTC resistor at the input, AX.
Program the model so that above a certain temperature, the heating is shut off and
the blower is turned on. This is to cool until a minimum value is reached. Then the
blower is to be shut off and the heating is to be turned on.
The current value for the analog input is to be outputted to a measuring device and
a text display.
