GSM-FUNCTIONS

A GSM modem can be connected to 203GT, making it possible for the user to communicate with the controller via
GSM phone text messages. (installation p. 37). A GSM phone can be used to carry out most of the user level
functions in this manual, e.g., measurements, settings, heating curve settings, supply water info and the
controllers operating mode. A GSM phone receives alarms which can be acknowledged by sending the alarms
back to the controller.

KEYWORDS

Send the following text message to the regulator:

If the regulator has a device ID (p. 37,38), always write the device ID

before the key word (e.g., TC1 KEYWORDS). The regulator will send a
list of key words via text message, which will help you obtain information
about how the regulator operates. Each key word is separated by a /
character.

Send a text message to the regulator using key words that it provides
you. The regulator recognizes only one request at a time, so write only
one key word/message. You can write the key word using capitals or
small letters. (If the regulator has a device ID (see p. 37, 38), write the
device ID in front of the key word.)

The regulator answers your request by sending the desired information.

With the GSM phone you can adjust heating curve settings, user level
settings or the regulator's operating mode.
Send the regulator a text message. Using key words, request information
about the function whose settings you want to adjust (or obtain the
information from your telephone's memory). Adjust the settings in the text
message that the regulator sent. Send a text message with the new
settings to the regulator. The regulator will make the requested
adjustments and acknowledge them by sending back a text message with
the new settings.

You can acknowledge an alarm with a GSM by sending the
same message back to the regulator.

Write the desired supply water temperature in place of
the previous setting in the text message "adjust” mode.

Write the setting in place of the previous setting

Put a star (* ) in front of the operating mode which you
want to start using. When you select manual operating,
regulator sends information about the supply water
temperature and valve positions (0-10Vcontrolled
actuators). Attention! When using electric manual control,
special caution has to be taken because of danger of
freezing and overheating. During the valve flush function,

the regulator first opens and then closes the valve.

After this automatic regulation continues. The purpose
of this function is to clean out a plugged up valve.
