4.3 - CONFIGURATION OF THE OUTPUTS
The outputs of the appliance can be configured in the group of
“
]
Out”
parameters, which contains the related
“Out1”, “Out2”,
“Out3”,
and
“Out4”
parameters
,
as well as the
“buF”
par
.
, which
allows the configuration of the internal buzzer (if fitted).
The outputs can be configured for the following operations:
= CooL
- for controlling the Cooling device (compressor or other)
= HEAt
- for controlling the Heating
= rh
- for controlling the humidification
= drh
- for controlling the dehumidification
= dEF
- for controlling the defrosting
= FAnr
- for controlling the air recycling fans (or in any case devices
used for favouring the exchange of heat and humidity between the
actuators and the environment)
= FAnE
- for controlling the air exchange / extraction fans (or in any
case devices such as dampers used for favouring the exchange of
air within the controlled environment)
= drhE
- for controlling the dehumidification device and the air
exchange / extraction fans (functions like drh and FAnE in or).
= LIGH
- for controlling the light
= AuS
- for controlling an auxiliary device
= ALt
- for controlling a silenceable alarm device through a contact
that is normally open and closed when alarmed.
= AL
- for controlling a non-silenceable alarm device through a
contact that is normally open and closed when alarmed.
= ALL
- for controlling an alarm device with a memory function
through a contact that is normally open and closed when alarmed.
= - ALt
- for controlling a silenceable alarm device through a contact
that is normally closed and open when alarmed.
= - AL
- for controlling a non-silenceable alarm device through a
contact that is normally closed and open when alarmed.
= - ALL
- for controlling an alarm device with a memory function
through a contact that is normally closed and open when alarmed
= On
- Output active when the appliance is in the On state. In this
mode, the output can be used for controlling the anti-condensation
resistance on the door of the cell, or for controlling lights or other
devices that require a power supply when the appliance is in
function.
= End
- Output active at the end of a work cycle for the time
programmed in the “btEd” par.. This mode can be used to activate
external signalling (optical or acoustic) indicating the end of the
cycle, or to activate external automatisms (for example, product
discharge automatisms).
= OFF
- Output disabled
The “buF” par. allows the buzzer to be enabled (= YES) or disabled
(=no).
4.4 - TEMPERATURE REGULATOR
All the parameters regarding the regulation of the temperature are
contained in the
“
]
rEG”
group
.
The regulation mode of the appliance is double-action ON/OFF-type
(also known as neutral zone) and it acts on the outputs configured
as
“CooL”
and
“HEAt”
on the basis of the measurements of the
Pr1 sensor, the active temperature Set Point
“SP t”
and the
intervention differential
“HStt”
.

Remember that the operation of the temperature regulator can be
conditioned by certain timing functions (protection devices for
compressor, defrosting etc.), and by some priority criteria (relating
to the control of dehumidification) described below.
4.5 - HUMIDITY REGULATOR
All the parameters regarding the regulation of the humidity are
contained in the
“
]
rEG”
group
.
The regulation mode of the appliance is double-action ON/OFF-type
(also known as neutral zone) and it acts on the outputs configured
as
“rh”
(humidification) and
“drh”, “CooL”
and
“HEAt”
(for
dehumidification depending on the setting of the “dhCn” par.)
on the
basis of the measurements of the Pr4 sensor, the active humidity
Set Point
“SP h”
and the intervention differential
“HSth”
.
Whereas the control of humidification occurs only through the
output configured as rh, the control of dehumidification can be
achieved in different ways, which can be established using the
“dhCn”
par. as:
= drh
- dehumidification occurs through the activation of the output
configured as drh.

compressor, defrosting etc.), and by some priority criteria (relating
to the control of temperature) described below.

RELATIONSHIPS
BETWEEN
CONTROL
OF
TEMPERATURE AND DEHUMIDIFICATION
If the appliance is configured to operate a dehumidification control
that also involves the temperature actuators (“dhCn”= drhC or HC),
and there is a simultaneous request for heating/cooling and for
dehumidification, the regulator will behave as follows:
