GSM-FUNCTIONS

OUMAN EH-201/L

When a GSM modem is connected to EH-201/L, a GSM telephone can be used to communicate with the regulator
via text messages (installation p 38).

Almost all of the user level functions that are mentioned in this manual

can be carried out using a GSM phone. These include measurements, settings, heating curve settings, supply
water information and the regulator's operating mode. Clock programs can be bypassed permanently or for
certain periods of time. Alarms are also directed to a GSM phone. They can be acknowledged by sending the
alarm message back to the regulator.

KEYWORDS

Send the following text message to the regulator:

If the regulator has a device ID (p. 35,36), always write the device
ID before the keyword (e.g., TC1 KEYWORDS). The regulator will
send a list of keywords via text message, which will help you obtain
information about how the regulator operates. Each keyword is
separated by a / character.

Send a text message to the regulator using keywords that it provides
you. The regulator recognizes only one request at a time, so write only
one keyword/message. You can write the keyword using capitals or
small letters. (If the regulator has a device ID (see p. 38,39), write the
device ID in front of the keyword.)

The regulator answers your request by sending the desired information.

With the GSM phone you can adjust heating curve settings, user
level settings, the regulator's operating mode, or time-controlled
relay operation. Send the regulator a text message. Using keywords,
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 temp.
and valve positions (0-10V controlled 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.

A GSM can be used to control the relay only if the
relay is being time controlled. Place a star (* ) next to
the control mode that you want to begin using. In time
control you can also set the length of time it is in
effect (range 0 …999 min).
