Select your type of air pump. To use this function, you need Ontech 9050, i.e. Ontech 9040 Master with the 'IR eye' (Ontech 9016).

Select the sensor that shall be used for temperature alarms and for the thermostat function.

An alarm SMS will be sent if the temperature drops below the set temperature. The temperature alarm will be automatically acknowledged when the temperature rises above the selected temperature. It is not possible to manually acknowledge this alarm.

Clear the input field to disable this alarm.

Set the time (in seconds) from the sensor is activated until an alarm SMS is sent.

This setting only applies to wired sensors connected to the master. See the Advanced Settings tab for changing the alarm delay for any wireless Ontech units.

Select if you want the relay on the master to get activated/deactivated in the case of an alarm.

Both NC (Normally Closed) and NO (Normally Open) alarm sensors can be used with the system.

Select the type you have connected by wire to the master unit.

Set the time (in minutes) from the unit detects a power failure until it sends an SMS.

If this is set to a mobile number, an alarm SMS will be sent to this number every time an alarm is generated.

The radio can be set to OFF if you do not have any extra units. It will also reduce the power consumption.

There is no need to change the channel unless you experiance communication problems with Ontech units. If the channel is changed, it must also be changed on all units.

When a relay is set for a specific time, this setting defines if the time should be counted in seconds, minutes or hours.

If this setting is OFF, no "low battery" message will be sent (only Ontech GSM 9025).

If this is set to a phone number, all status and update requests will be sent to this number instead of the mobile phone that sent the original request.

Only for Ontech GSM 9025: If you have a GPS connected, this will set the allowed size of the GPS Fence function.

Select ON if the master is powered by 24V. This setting only affects at which battery level the "battery low"-SMS will be sent (only Ontech GSM 9025).

If this setting is OFF, the red LED will never blink when there is an alarm.

Server mode only works for the master relay. It means:
1. Relay is always ON after power failure.
2. It is not possible to control the relay with the button.
3. It is not possible to control the relay with SMS, except that the Relay timer function will still work. With Relay timer it is possible to turn the relay OFF for a specific number of seconds (or minutes). This is useful to restart the server.
4. Alarm will always be activated and is not possible to deactivate with SMS.

If this is active, you can connect a 4-20 mA sensor to the third pin of the temperature sensor connector. The 4-20 mA signal will be converted to a value between 0% and 100%. It also is possible to connect a 0-10V sensor to this pin.

ON (no SMS) means you will not get any SMS when no current is detected.

Contact us for more information (www.ontechgsm.com).

An SMS will be sent every time the 4-20 mA sensor goes under this level.

An SMS will be sent every time the 4-20 mA sensor goes over this level.

You can:

• Program a phone number to position 1 to 3.
• Delete a previous programmed phone number in position 1 to 3.
• Get the programmed phone number in position 1 to 3. You will get the position and the last six digits of the programmed phone number (example: "02;654321" means position 2 and then the last 6 digits of the phone number).

Select the position (1 to 3), where you want to store (or delete) the phone number.

Enter the phone number that you want to program.
