If the actual temperature is above the setpoint plus the second positive tolerance,
an error identifier is set (bit 2 in the appropriate error byte) and the controller is

is entered, the tolerance is not effective.

tolerance, an error identifier is set (bit 3 in the appropriate error byte) and the
