TIME/ASTRONOMICAL SWITCH WITH BLUETOOTH
Read all instructions carefully
Electronic digital switch for the management of electrical loads over time through the relay
(channel) available on board. Allows time programming (periodicity: daily or weekly) or
astronomical (from sunset to sunrise). The Bluetooth interface allows it to be coupled with
smartphone or tablet thanks to the free app. The application allows complete management
of the device, allowing you to program and make settings directly on your smartphone, and
then transfer all the data to the time switch. The reverse procedure is also possible, i.e. to
copy the programming of a time switch on your mobile device. The backup battery allows
you to keep the settings even in case of black-out and can be replaced through the cover
on the front of the device. micro BT is an electronic device that perform actions of 1B type,
intended to operate in environments with overvoltage category III and pollution degree 2
according to the EN 60730-1 standard.

information to users pursuant to art. 14 of the directive
2012/19 / EU of the european parliament and of the council
of 4 july 2012 on waste electrical and electronic equipment (WEEE)
If the crossed-out bin symbol appears on the equipment or packaging,
this means the product must not be included with other general waste
at the end of its working life.
The user must take the worn product to a sorted waste center,
or return it to the retailer when purchasing a new one.
Products for disposal can be consigned free of charge (without any new purchase obligation)
to retailers with a sales area of at least 400 m
2, if they measure less than 25 cm.
An efficient sorted waste collection for the environmentally friendly disposal of the used device, or its
subsequent recycling, helps avoid the potential negative effects on the environment and people’s health,
and encourages the re-use and/or recycling of the construction materials.

9LED SIGNALS
The 2 LEDs on the device allow you to understand the operating status of the device, according to the types of switch on described in the table:
LED Type of switch on Operating status
GREEN
Steady on Normal operation
Fast ashing Connection with smartphone successful
Short switch on Low or no battery (replace the battery)
Short switch o Time or date not congured
RED
Steady on Relay status ON
O Relay status OFF
Short switch on Relay status LOCK OFF
Short switch o Relay status LOCK ON
Fast ashing Anomaly (reset the device see BOX 4)
+ REDGREEN
Fast alternating ashing Device reboot
Simultaneous fast ashing Keypad lock enabled (displayed when the key is pressed)
Simultaneous slow ashing Anomaly (remove power from the device for at least 30 seconds and power it back on)
In this condition, when mains power returns, the display will flash, the time
start from 00:00 o’ clock of 01.01 and the relay stays in OFF position. In this
case, to resume the normal operating, set time and date.
Use only CR-1632 type batteries.
It is necessary to remove the batteries before the instrument is scrapped.
In case of replacement, dispose of the batteries in the special
containers of separate waste collection.
Warning: before accessing the battery compartment, disconnect the power
supply
Warning: in order not to lose carried out settings, it is necessary to ensure
that the time for the battery replacement doesn’t exceed 60 seconds
(in absence of power by means)
8DEPLETED BATTERY
When the backup battery is close to empty, the green LED flashes briefly.
In this condition, replace the battery as soon as possible, by accessing the
battery compartment, to avoid that, in case of blackout, the date and time
are lost.
7KEYBOARD OPERATION
The key on the device, depending on the type of pressure exerted,
is used to perform the operations described in the table:
Pressure type Function
Short pressure Manual relay ON/OFF switching
Long pressure (> 3 sec) Lock (or unlock) the switching of the relay
Prolonged pressur (> 10 sec) Reset settings: reset all settings to factory default
NOTE: If the keyboard lock has been set by the app, all key presses will be
ignored. To unlock the device in case it is not possible to access the app,
you need to remove and reapply power to the timer and reset the device
(see Box 4). The keyboard remains unlocked for 30 seconds, which is
enough time to perform the procedure to restore default settings.
5INSTALLATION AND PRELIMINARY OPERATIONS
6CONFIGURATION REMOTE CONTROL
• The device is provided with inserted date, hour and backup battery.
• Install and connect the device respecting the connection diagrams shown
in this manual.
• Access the store of your smartphone, install and start the free memo – Vemer app.
• Check that the Bluetooth and the GPS of your smartphone are active and the consent
to the memo - Vemer App to be able to identify the position (GPS) is enabled
(adapt the settings on the smartphone such as to be able to perform this tracking;
for further information see the instructions of your smartphone). .
To configure the device using a smartphone, proceed as follows:
1. Start the and press theApp “+” key
present on the Home page
2. Press the Bluetooth connection box and select
the Connect key
3. Find and select the device in the “MICRO BT”
list to connect to the timer (the green LED
will start flashing quickly to indicate that it has
happened connection between app and device).
Notes: all the Bluetooth devices detected nearby
are displayed: select the device to be associated
from the list. Each device is identified by the
product code (for example VE797200) and by
the serial number (for example 12340003) and
the name of the model (for example MICRO BT).
Warning: make sure that the micro BT is mains
powered, otherwise the Bluetooth interface is
not active and the device is not visible.
4. Confirm received on your phone the double Bluetooth pairing notification
by entering the password to pair the micro BT with your phone (if not changed the
password is 123456) and wait for synchronization with the device.
5. After successfully completing the procedure, the app displays the initial page of the
selected microBT .
From this page it is possible
a. Create new programs which will then be copied to the micro BT
b. Change the micro BT settings
c. View the parameters and associate an alias (name that identifies the device,
such as “external lights”) to the micro BT
d. Manually control the relay output and activate the random switching function
Note: The communication between app and micro BT is point-to-point.
This means that, even in the presence of multiple devices, the app can
communicate with only one at a time.
4DEVICE RESET
Perform a reset to delete the settings and programs entered and return the device
to factory settings. To reset, hold down the button (at least 10 seconds) until the LEDs
start to flash alternately.
Important: when the device is turned on for the first time or by performing
a factory reset, the
Bluetooth connection password is 123456
