them manages a different operating mode, so each thermostat must be of a type compatible with
the operation for which it has been installed. The thermostat connected to the cooling input (TAF)
should demand (closed circuit signal) when the room temperature is higher than the desired
temperature (setpoint temperature), and in turn, the thermostat connected to the heating input
(TAC) should demand (closed circuit signal) when the room temperature is lower than the desired
temperature (setpoint temperature).

As indicated in the figure, if the setpoint temperatures of the room thermostats are selected in such
a way that both require simultaneous operation, the electronic control of the heat pump will start
to operate in “Manual” mode, that is, the Heating/ Cooling Operating modes must be selected
manually from the control panel. To avoid this situation, it is essential to
