4. Quick access parameter setting
The controller provides the following functions with a simple button press:
• Switch on and off
• Setpoint setting
• Fancoil operating mode
• MODE button functionality
The
MODE
button can be assigned one quick access function and two normal access functions, depending on parameter
I44
(see
“MODE button functionality” page 9
)
I44
=0: season changeover (if it is local, for 2 pipe systems)
I44
=1: timer extension.
I44
=2: operating mode (without clock, with time program, holiday)
• Keyboard lock:
To lock the keyboard, press simultaneously buttons
ESC
M
O
D
E
, script
LK
appears on display for one second.
It is then not possible to access parameters if a key is pressed, script
LK
appears on display for one second.
To unlock the keyboard, simultaneously buttons
ESC
M
O
D
E
, script
NLK
appears on display for one second.
• Switch on and off
Switching on and off can be done in two ways: with an external contact or manually If one of the digital contacts is config
-
ured as “Remote On/Off”(
M03
=1 or
M05
=1) or one of the sensors is used as a digital input configured as “Remote On/Off”
(
M07
=4 or
M09
=4 or
M11
=4), the device can be switched off remotely by positioning the contact appropriately.
On this case the display A shows
OFF
and the display B shows
rem
if keyboard is not locked or
Lrem
if keyboard is locked.
Example for digital input 1 (
M03
=1):
Unit ON=
(
M04
=0)
Unit OFF=
(
M04
=0)
Unit ON=
(
M04
=1)
Unit OFF=
(
M04
=1)
If the device is switched on by an external contact, it is however manually possible to switch on the device by pressing
button until
ON
or
OFF
is displayed.
When the device is switched off by an external contact, it is not possible to switch it on with button
.
If the device is off, all outputs are deactivated except heating outputs in case of frost protection (see
“13. Frost protection”
page 24
).
If external contact is not used as remote on/off, when unit is switched off manually, the
display A shows
OFF
and the dis-
play B shows nothing if keyboard is not locked or
Lc
if keyboard is locked.
• Setpoint setting
Based on parameter
I52
value(CONFORT function), it is possible to modify directly the setpoint if
I52
=0 or to set only a
variation of ±3°C [±5°F] if
I52
=1. On the last case, this offset is added to the setpoint
I07
,
I08
,
I09
. This function is used
when it is necessary that the setpoint is not directly accessible to users.
With
I52
=0 pressing the
or
button, the value of actual setpoint is shown corresponding to setpoint
I07
(for heat-
ing mode
M01
=0..7) or
I08
(for cooling mode
M01
=2..7,10,11) or
I09
(for 4 pipes operating mode).
The “
set
” icon flashes. With the
or
button it is possible to modify the value; the new value is automatically saved.
With
I52
=1 pressing the
or
button, the value of offset to apply to current setpoint is displayed.
The icon “
°C
” or “
°F
” is flashing based on actual unit. With the
or
button it is possible to modify the value; the
new value is automatically saved.
To exit the setting menu, wait for 4 seconds or press button
ESC
