16 HouseControl User’s Manual version 4.8
x = Directory memory cell (0 through 20, cell 0 is reserved for the GSM operator’s SMS
Service number and it should be set only if the number is missing from the SIM card)
aa = User’s GSM phone number
b = Permission level (optional, see 2.5.2)
It is always advisable to check the contents of the phone directory before making any modifications to it
so that you will not accidentally overwrite an existing phone number.
The following commands are used for displaying and editing the contents of the phone directory:
Asking the contents of the directory
# P ?
This will print out the 21 phone numbers in the directory (0 through 20)
Asking a single phone number
# P x ?
x = Directory memory cell number (0 through 20)
Removing a phone number
# P x
x = Directory memory cell (0 through 20)
This will clear the memory cell x.
2.5.2 Permission Levels
Permission level can be assigned to a phone number by appending a number from one to three at the
end of the actual phone number (see 2.5.1). All phone numbers have unlimited rights (level 1) by default.
All phone numbers can receive alarm messages irrespective of the permission level if they are placed in
the five first directory memory cells.
Level 1: All rights (this level is used if no parameter b is given in command #P).
Level 2: The user can receive alarms and send commands to set relays on and off.
Level 3: The user can only receive alarm messages.
Level 4: The user can receive alarms and send so-called macro commands (e.g. #HEATING ON)
2.5.3 Wild-Card Characters
You can use so-called wild-card characters in the phone numbers you add in the phone directory. Wild-
card characters enable the use of your HouseControl even if the phone number is not kept in the
directory in its entirety. Two wild-card characters are available: ? matches any digit (exactly one) and *
matches zero or more digits. For example, command #P2 * 2 grants permission level 2 to all phone
numbers.
If wild-card characters are employed in the phone numbers, information security issues must be
considered carefully. You should never grant permission level 1 to any number taking advantage of the
wild-card characters. It is recommended that you use permission level 2 for these phone numbers. This
prevents the modification of the unit’s settings from phone numbers that contain wild-card characters.
) If a phone number contains wild-card characters, no alarm messages are sent to the numbers
matching the pattern.
A hint: The Company that performs the installation of your HouseControl can leave their maintenance
phone number or their TeleCont monitoring room application phone number in the unit’s phone directory.
The maintenance worker is able to adjust the settings of the device without being physically present. You
can block alarm messages from the phone number by appending character * at the end of the phone
number.
