Con guration 2 (AdC = 2) - DiP 4 has no e ect
Used to control a classic system with air-conditioner/heat pump and
heating/cooling call.
Automatic operating mode is signalled on the display by the AUTO
symbol, next to the set point.
Two set points need to be de ned, one for cooling and the other for
heating.
The mode switches between cooling and heating automatically
according to the room temperature measured.
The two set points are set by pressing the SET button or the up or down
button,  rst the cooling set point is displayed and then the heating set
point, the controller automatically checks that there is a di erence of at
least 1°C between the two set points.
Relay 1 controls the heating/cooling signal. Relay 2, on the other hand,
manages the changeover.
See the following graph for the description of this operating mode when

Con guration 3 (AdC = 3) - DiP 4 has no e ect
The typical application in this case is a condensing unit, reverse-cycle
with ON/OFF control of the outlet fan and automatic changeover.
Automatic operating mode is signalled on the display by the AUTO
symbol, next to the set point.
Like in the previous con guration, there are two set points, one for
cooling and the other for heating, both of which can be set.
The mode switches between cooling and heating automatically
according to the room temperature measured.
The two set points are set by pressing the SET button or the up or down
button,  rst the cooling set point is displayed and then the heating set
point, the controller automatically checks that there is a di erence of at
least 1°C between the two set points.
Relay 1 is controlled directly by the ON/OFF button on the instrument,
when the instrument is o relay 1 is o , when the instrument is on the
relay is always active.
Relay 2, on the other hand, manages changeover.
The analogue output is dedicated to heating/cooling control.
Relay 1 = FAN control based on the status (ON/OFF) of the clima
controller.

5.7 (T2A + H) automatic temperature and
humidity control
This operating mode can be used to perform two types of control (be
selected by parameter Adc):
automatic cooling/heating selection for systems with air-conditioner •
and boiler, with humidi er control
reverse-cycle systems with heating and cooling set point and •
humidi er control.
