variable. In case of a long reset time, the controls react somewhat more gently and
needs longer until the necessary variable for the set point deviation is reached.
You should set the time appropriate to the heating system at this point (note
manufacturer instructions).
Maximum control variable is reached

Reset time (in min.)
Now determine what should be transmitted when the control is blocked. Set a value
greater 0 (=OFF) to receive a basic heating level, e.g. for floor heating.
Upon release, the control variable follows the rule again.
When blocked, the variable shall

In case of a common variable for heating and cooling, 0 is always transmitted as a fixed
value.
