Send a text message to the controller using the key words given by the controller. The
controller only identifies one request at a time, so write only one key word/message.
You can write the key word using capital or small letters. (If the controller has an
equipment ID (p. 48), write the equipment ID in front of the key word).
The controller answers your request by sending the requested information via text
message.
You can change user level settings and supply air unit control via a GSM phone. Send
a text message to the controller and, using a key word, request information about the
function whose settings you want to change (or obtain the information from your
telephone's memory). Change the text message sent by the controller and send the
changed message to the controller. The controller makes the requested changes and
acknowledges by sending a text message showing the new settings.

COMMUNICATION WITH THE CONTROLLER VIA GSM:
Settings
Keyword:
Change to the text message sent by the controller
Obtaining information from the controller via GSM:
In the text message the *character indicates the control mode in use.
To change the control mode: Move the * character to the control mode
you want to use and send the message to the controller. E.g., If you want
to change AH unit running from automatic control to manual 1/1
(maximum) output, delete the *character from in front of automatic control
in the text message you received and put the *character in front of manual
1/1 (Manual max).
Alarm acknowledgement:
You can give the controller the GSM numbers (max. 2) that you want the alarms
directed to. The cause of the alarm is clearly stated in the alarm message. The alarm
is acknowledged when the GSM sends the same message back to the controller.
When the alarm arrives, the GSM 1 immediately receives the alarm information. If the
alarm is not acknowledged, the controller sends a new text message to both GSM
numbers 5 minutes after the alarm has appeared.

EH-105 can be connected to a GSM modem, making it possible to
communicate with a GSM phone via text messages. (initialization p. 49).
The functions performed using a graphic user interface (see p. 21) can
also be performed using traditional text messages.

If the controller has an equipment ID (p. 48), you must write the equipment ID in front of
the key word (e.g.,TC1 KEY WORDS). You don`t need the equipment ID if you have
only one controller in use. The controller sends a list of key words as a text message,
from which you can receive information about the controller's operations. Each key
word is separated from the others by a / character.
