The state (heating or cooling) of the thermostat can be monitored with the ACS tool
(diagnostic value “Control sequence”). The last active mode is displayed when the
thermostat is in the dead zone or temperature control is disabled.
With a 2 pipe application, the control sequence state is determined by the
application mode (see section 3.6.2) and by the state of the heating / cooling
cha
ngeover signal (via local sensor or bus), or fixed according to the selected
control sequence (P01 = heating (0) / cooling (1)).

With a 4-pipe, 2-pipe with electric heater, and 2-pipe with radiator application, the
control sequence state depends on the application mode and on the heating /
cooling demand.
