5.5 (T2 + H) two-stage temperature and
humidity control
This is used in applications with two outputs dedicated to temperature
control to send a start signal to an air-conditioner or heat pump/boiler
with two steps. The analogue output is for humidi cation control when
the controller is in heating mode. If the controller is in cooling operation,
humidity control is disabled, and if attempting to change the set point the
lock symbol is shown.
Dipswitch con guration:
dip1: ON
dip2: OFF
dip3: ON
Control is available in both cooling and heating (dip4).

5.6 (T2A) automatic temperature control
only
This control mode is available on products with two relay outputs for
temperature control (ADCA******) and is used to have three di erent
types of automatic cooling/heating control. Typical applications: air-
conditioner plus boiler, air-conditioner/heat pump, condensing unit.
Once having selected the basic con guration using the dipswitches, the
three operating modes available are selected by parameter (Adc).
Dipswitch con guration:
dip1: OFF
dip2: ON
dip3: ON
Con guration 1 (AdC = 1)
For the control of a classic system with air-conditioner + boiler. The
controller sends to the start signal to one or other appliance-
Automatic operating mode is signalled on the display by the AUTO
symbol, next to the set point.
The analogue output is de ned for one function only, heating or cooling.
The selection is made using dipswitch 4 located on the rear.
