Credit Function; Interfaces; Led1: Gsm Signal Level; Led2: Status Of The Relay Output - Elbro SMSB12T Manuel De L'utilisateur

This function (RMODE) offers the following modes:
• function disabled
• SWITCH mode: the relay is simply toggled (ON and OFF), this mode disables the thermostat function
• PULSE mode: a pulse (definable from 1 – 20 seconds) is emitted, this mode disables the thermostat function
• AUTOMATIC mode: Toggle between the automatic room thermostat function and the antifreeze temperature (the temperature sensor
has to be activated in advance)
The user may also choose to activate the SMS feedback option, which sends an SMS confirming the status of the relay back to the cell
phone from which the telephone call was received. The SMS feedback in PULSE-Mode is fully customizable

Credit Function

This function, when enabled, allows the user to request the remaining credit on the used prepaid SIM card. This way, the user always has an
overview about the remaining credit and to make sure the SIM card does not run empty, making it impossible to send status messages and
alarms.
As each telephone company uses a different method of indicating the remaining credit to users, this function may be set in one of the
following three modes most commonly used by telephone operators:
• Using a quick command
• By calling a number to receive an SMS indicating the credit
• By sending a free SMS with a command to receive the credit indication
Please consult your telephone company to find out which parameters have to be entered to receive credit information.
This function is not fully guaranteed as the telephone companies use different methods to indicate the remaining credit.
