ATTENTION
If the regulator is set in heating mode, the hysteresis operation has the opposite character,
i.e. the heating system is switched off after the temperature has dropped below the set value,
taking into account the value of the programmed hysteresis.
7.2.
Control of the stirrer’s motoreducer
.
The working status of the stirrer is signaled by two red LED (
see section 3.
):
−
signaling of switching on the stirrer’s motoreducer
[8]
,
−
indication of the stirrer operation mode
[7]
.
The regulator has two modes of stirrer operation, i.e. automatic or manual, which are described in
detail below.
7.2.1. Automatic stirrer operation.
In this mode, depending on the settings of parameters
F0
,
E1
and
E2
, the stirrer may be connected
to the operation of the unit or completely independent of the operation of the chiller (unit)
(
see section 9.
).
The stirrer operation setting in the automatic mode is signaled by the continuous lighting of the red
LED
[7]
.
The stirrer's operation can be switched off at any time by means of the
[2]
button (
see section 3.
),
except when the
F0
parameter is set to 2 or 3.
Switching off the regulator by pressing the
[1]
button also turns off the stirrer operation.
7.2.2. Manually triggered stirrer operation.
The manual stirrer operation can be initiated by pressing the button marked by symbol
[3]
(
see section 3.
); at this point, the automatic operation of the stirrer stops and the manual operation
starts. Manual operation of the stirrer is also possible when the regulator is switched off (button
[1]
)
or stirrer operation switched off (button
[2]
). The setting of the stirrer operation in manual mode is
signaled by a flashing red LED
[7]
.
The manual operation of the stirrer is not interrupted when the regulator is switched off manually
by pressing the
[1]
button.
The stirrer operation in this mode can be interrupted at any time by pressing the button
again.
The manual stirrer operation can take place in two variants, depending on the
CP
parameter settings:
−
setting the value 0 means continuous stirrer operation,
−
setting the value >0 means that the stirrer operates for the set number of minutes; after
the time set elapses, the manual operation of the stirrer is switched off.
ATTENTION
No light signaling of the stirrer operation
[7]
[8]
when the regulator is switched off means that
the automatic stirrer operation has been switched off, at the same time the manual operation
has not been switched on.
