WATER CONTROL
Enabling of the dehumidifi cation function is tied to the water
temperature. The related enabling logic is described below
If enabling conditions do not exist, the dehumidifi cation fun-
ction will be temporarily inhibited. The same will occur in the
event that the sensor is disconnected.
N.B.: once the target level of humidity is reached or the
controller is switched off, the dehumidify option will
be unselected
DISPLAY
The display shows the following information
■ Dehumidify ON: symbol lit
■ Dehumidifi cation temporarily inhibited: fl ashing symbol
PROGRAMMING OF TIME SCHEDULES
GENERAL FUNCTIONING
Time schedules ar
e programmed by setting the dedicated
parameters (H parameters) in a suitable manner and in the
correct sequence. The procedure for accessing parameters
and the meaning of each parameter are thoroughly described
in the paragraphs below. It is possible to set two different
types of time schedules:
■ ON/OFF time programming: each time slot can be as-
sociated with a controller ON or OFF status, so that the
controller will automatically switch on or off according to
the time of day.
■ temperature SETPOINT programming according to time
of day: each time slot can be associated with a SUMMER
temperature SETPOINT (for cooling) and a WINTER tempe-
rature SETPOINT (for heating), which will be automatically
used by the controller as the temperature SETPOINT
(adjustable by the user within a range of ±2°C) according
to the time of day and current operating mode.
Two daily profi les can be defi ned, each of which divided into
three time slots. Each day of the week can be associated with
one profi le or the other.
