LED status at boot time

LED color Status Descriprtion
../_images/red_led.png Fast blinking The WE110 is booting
../_images/red_led.png Turned-on for 5 seconds, then it will reboot Network registration error or SIM error
../_images/blue_led.png Fast blinking for 3 seconds From this moment, the WE110 is fully operative

LED status at normal operation

There are two normal conditions that are shown with two different LED status

  • The system LED (green)
  • The signal LED (red or blue)

System LED

In thermostat mode:

LED color Status Descriprtion
../_images/green_led.png Slow blinking, each 0.640s The system is active and the relay is opened
../_images/green_led.png Turned-on The system is active and the relay is closed
../_images/black_led.png Turned-off The system is inactive

In telecontrol mode:

LED color Status Descriprtion
../_images/green_led.png Slow blinking, each 0.640s The relay is in pulse mode
../_images/green_led.png Turned-on The relay is closed
../_images/black_led.png Turned-off The relay is opened

Signal LED

LED color Status Descriprtion
../_images/blue_led.png Turned-on The signal is good
../_images/blue_led.png Slow blinking, each 0.64s The signal is sufficient
../_images/red_led.png Slow blinking, each 0.64s The signal is not good

For example if the relay is closed and there is a sufficient signal, the LED status will blink in the following way:

../_images/led_example1.png

All setup and control activities of the device are carried out sending and receiving SMS messages.

Note

The text in bold denotes strings to be typed and sent to the device.

For example, STATUS means that a SMS containing the word STATUS will be sent to the device.

WE110 can operate in two different ways, that can be selected using the SET command, as explained below:

  • Thermostat: for both air conditioning and heating applications
  • Remote control for general use

WE110 is factory preset to operate in heating thermostat mode.

To request systems status send a message to the device with the STATUS command. The device replies with a SMS carrying all the status information.

To enable the thermostat function and preset temperature to 20°C degrees send ON 20. To switch off the thermostat relay send OFF command.

GREEN LED in Thermostat mode: GREEN ON, thermostat enabled, heating on Blinking GREEN, thermostat enabled, heating off GREEN OFF, thermostat disabled, heating off

To switch on the relay output, in general remote control mode, send ON command. To switch off the relay send OFF.

In both operating modes (thermostat and remote control) the output switch-on and switch-off can be controlled also sending a RING (i.e. calling the number of the WE110). WE110 hangs up and sends back a RING to the caller to confirm that the command has been received and executed. Note: this way of controlling output is enabled only if the caller number has previously been inserted in the users list, through the USER command explained below.

GREEN LED in general remote control mode: GREEN on, output active, relay contact closed Blinking GREEN, output active in pulsed mode GREEN off, output disabled, relay contact open

WE110 can be programmed to reply with a confirmation message every time a command is received and executed. To enable the confirmation message send the command CONFIRM ON. To disable the feature send CONFIRM OFF.

4.1. Front panel button

The button located in the front panel has the following functionalities if an alarm condition has not been programmed:

  • In remote control mode, when shortly pressed, allow to change the output state
  • In thermostat mode, when shortly pressed, allows to enable or disable the thermostat feature

5. Using the device: APP

6. Using the device: SMS

6.1. User management

Up to five users can be inserted in the users list. Only registered users will be able to operate the device and will receive messages in case of alarms or programmed input conditions.

To add user 1 to the list send the following command:

USER 1 <tel number>

For example:

USER 1 +391231231234 - Adds user 1 that has phone number +391231231234

USER 2 +394564564567 - Adds user 2 with a phone number +394564564567

To delete users from the list send the USER command followed by the number of the user to delete:

USER 1 - Delete user 1 from the list.

USER 2 - Delete user 2 from the list.

To receive the full list of enabled users send the USER command with no additional parameters.

6.2. Alarm management

When using the device in thermostat mode, the thresholds too-hot and too-cold can be preset. When the measured temperature reaches the preset thresholds the device sends an alarm message to all users in the users list.

To set the too-cold threshold (anti-freeze feature) send the command:

NOFREEZE 6 Too-cold alarm

The text Too-cold alarm is an example of the alarm SMS message. It can be customized by the user.

To set the “too-hot” threshold, send:

OVERTEMP 25 Too-hot alarm

The text Too-hot alarm is an example of the alarm SMS message. It can be customized by the user.

The command FREEZE ON programs the device to close the relay output automatically when the measured temperature goes lower than the too-cold threshold.

The command FREEZE OFF disables this feature.

When using the device in remote control mode, it’s possible to send a SMS when the input signal changes state. For example, the command

ALARM 1 ON 60 Alarm

sends a message with the text Alarm 60 seconds after the digital input is closed.

6.3. GSM signal level

To know the GSM RF signal level send the SIGNAL command. The device replies with a level number between 1 and 30:

  • 1 to 7: GSM signal is too low for a correct operation of the device
  • 8 to 12: GSM signal is low
  • 13 to 18: GSM signal is good
  • Higher than 18: GSM signal is very good

6.4. Factory reset

To restore the device to its factory default send the command DEFAULT.


6.5. Advanced SMS

ALARM <input state> <ON/OFF> <delay> <message>
Enable an alarm condition: the WE110 sends the specified alarm message when the digital input changes its state. It’s possible to program two alarm conditions at the same time: one when the digital input contact closes and one when it opens
<input state>

0 – sends the message when the contact opens

1 – sends the message when the contact closes

<ON/OFF>

ON to enable

OFF to disable

<delay> Delay in seconds before sending the specified message when the digital input changes state
<message> The user-defined message
Example

ALARM 1 ON 60 Alarm

Send an alarm SMS message 60 seconds after the the contact closed

Example

ALARM 1 ON 60 Alarm

Send an alarm SMS message 60 seconds after the the contact closed

CENTER <SMS center number>

SET <mode> <offset> <delay> <param>
Set WE110 operating mode
<mode>

Operating mode:

1: Heating thermostat 2: Cooling thermostat 3: Remote control for general user

<offset>

In Thermostat Mode: Correction applied to the measured temperature (tenths of °C are added to the measured value)

In Remote Control Mode: the time that the output relay will remain closed when activated (when zero the output is always ON/OFF, otherwise the output is in pulse mode)

<delay>

In Thermostat Mode: output activation delay

In Remote Control Mode: Discarded

<param>

In Thermostat Mode: thermostat hysteresis in tenths of °C

In Remote Control Mode: Discarded

Example

SET 1 10 120 5

Set WE110 to operate in heating thermostat mode, with a correction on temperature measurement of +1°C, a delay of 120 seconds and an hysteresis of 0.5°C. This means that when the thermistor measures 18°C, the device switches on the output at 19,5°C and switches off at 18,5°C, after a delay of two minutes).

6.6. Chronothermostat commands

CLOCK
Through this command it’s possible to get the time information, if previously set on the WE110.
CLOCK MAN
Through this command is possible to set the clock in manual mode. The WE110 will extract the correct date and time from the same command SMS. In case of power failure, if the WE110 is in manual mode, all clock settings will be lost until the next sending of a CLOCK MAN command.
USER 0 <phone> CLOCK AUTO
The first command defines the number of the SIM Card inserted in the WE110. This number must be recorded exclusively on position 0, in order not to loose the time settings in case of device’s shut down. The WE110 extracts the time settings automatically from the CLOCK AUTO message and sends an SMS to its own number everytime the device switch off/on, in order to restore the time settings.
PROG <days> <starting time><temperature> [<starting time><temperature> <starting time><temperature> …]
With the command PROG it’s possible to set all configurations of the chronothermostat
days days of the week: * 1: monday * 2: tuesday * 3: wednesday * 4: thursday * 5: friday * 6: saturday * 7: sunday
<starting time><temperature>

starting time: it defines the starting time in 24 hours format 08:00

temperature: indicates the temperature required from the time set, expressed in format: “T”+”temperature” in Celsius degrees T21

It’s allowed to set max 6 time intervals for each program. The time must be entered considering mutiples of 15 minutes.

Instead of temperature it’s possible to set the switch off/on of the device through the parameters OFF and ON. The parameter ON, will take as reference the temperature originally set in the thermostat.

Example PROG 125 08:00T21 09:30T18 11:15OFF 13:30ON 17:45T25
CRONO
Switches on the chronothermostat function.
CRONO OFF
Switches off the chronthermostat function.
SWITCHON <temperature> <hours>
It switches on the thermostat for a certain interval, without programming the chronothermostat.
temperature
temperature: this is the parameter, that the WE110 takes as reference for setting the
temperature.
hours hours: this indicates the time the WE110 has to keep the set temperature before switching off
Example SWITCHON 23 4
