Parameters for the regulation type
(this menu varies depending on the chosen regulation type)
If the chosen regulation type is on/off, set the differential
GLI
.
Allowed values: 0.1°C ÷ 1°C Factory value: 0.3 °C
If the chosen regulation type is proportional,
set the band
EQG
and the period
SHU
.
Allowed values: 0.5°C ÷ 5°C (band), 10, 20 or 30 minutes (period).
Factory value: 0.5 °C (band), 10 minutes (period).
Adjustment of the measured temperature
In particular installation conditions, it can happen that the temperature
measured by the device deviates from the average temperature present
in the room. In this case, introduce an adjustment temperature with
the ADJ menu.
Allowed values: -5°C ÷ 5°C Factory value: 0 °C.
Note: the temperature value shown on the display during normal operation is
inclusive of any adjustment introduced.
Antifreeze temperature
(this menu is active only if operating mode = heating)
The antifreeze temperature avoids the risk of freezing of the system
when on the chronothermostat is set the off operation
.
Allowed values:
, 1°C ÷ 50°C Factory value: 6 °C.
Note: the “
” setting excludes the antifreeze function; in this case,
when the device is off, no minimum temperature is guaranteed
Type of regulation
(this menu is active only if operating mode = heating)
Setting up:
•
O
to choose on/off regulation.
•
P
to choose proportional regulation.
Factory value:
O
(on/off).
Note: the on/off regulation is suitable for most home situations.
Therefore it is advisable to modify this parameter only in case of real need.
Wi-Fi connection configuration
This sub-menu consists of 3 different screens and described below.
To switch from one screen to another, use the keys
and
.
• the device PIN. It is a 4-digit number necessary to associate the device
with your Vemer account.
This screen also shows:
- the status of the Wi-Fi connection:
on fixed: device connected to the home network
flashing: search for Wi-Fi network in progress
- the association between the device and Vemer account:
on fixed: associated with a Vemer account
flashing: not associated with any Vemer account
Note: during the first 20 seconds or so of this screen viewing
the icon is always flashing.
• the MAC address of the device. It is a sequence of characters that identifies
uniquely a device inside of a network of devices (reading must be done from
left to right. In the example: C28d7b)
• the intensity of the signal between the device and the router (FLD).
For values:
- higher than -60dB: excellent signal quality
- between -60dB and -90dB: good signal quality
- lower than -90dB: poor signal quality that could compromise communication
between device and router. In this case, bring the device closer to the router.
Minimum/Maximum settable temperature
Under particular installation conditions, for example in public buildings, hotels,
etc., it may be useful to limit the range of values that the temperatures T1/T2/T3
and Tm can assume, in order to prevent incorrect settings by the user.
•

Password for key lock
Under particular installation conditions, for example in public buildings, hotels,
etc., it may be necessary to lock the keypad to prevent changes to the settings
by unauthorized persons.
To activate the keypad lock, set a password between 001 and 999.
To deactivate the lock, press the key
until you set “--”.
When the keypad lock is active, the symbol appears on the display and,
after pressing a key, the word BL0C appears.
To find out how to unlock the keypad, see “Keypad unlock”
Hour meter of system operation
It displays the operating hours of the system (relay contacts on C-NA).
The device has two counters (5-digit) independent for heating operation
and for the conditioning operation, but is displayed only the counter
of the selected operation mode.
To reset the counter, press the key
for a long time during the display.
The maximum count is 65535h (about 7 years), when this digit is reached,
the counter resumes the count from 0h.
Perform a reset to cancel the settings made and bring the device back to the conditions in which it
appears as soon as it has been removed from the packaging.
To reset:
1. from the initial screen, press the key
to enter the configuration menu.
The CLOCK indication flashes.
2. press the keys

If the program meets the needs:
• press the key
once to confirm and choose another day to which to assign a different program
• press the key
twice to return to the configuration menu
• press the key
three times to exit the menu and return to the initial screen
If no program meets the needs:
• choose the one that is closest to you and press the key
to customize the profile:
- starting from midnight 00:00, press the keys
and
to assign to each hour of the day
one of the 3 possible temperatures (T1, T2, T3) and the key
to confirm and go to the next
hour.
- to enter a switching delay for the selected hour, press the key
for a long time.
For more information about switching delay, see “How the switching delay works”.
When the profile program is suitable for your needs:
• press the key
to exit the customization.
How the switching delay works
Set a switching delay for a specific hour to maintain, for the duration
of the delay, the temperature value assigned to the previous hour.
For example, if the program includes:
T2 from 12 to 13 and T3 from 13 to 14 pm with 30 minutes delay
the chronothermostat adjusts the temperature based on the value of
T2 from 12 to 13.30 and T3 from 13.30 to 14.00
It is possible to set delays of 15, 30, 45 minutes, independent for every hour of the day.
