In case of sensor fault, the regulator gives an alarm and a message
appears on the display: Alarm! Measurement number and name and err.
The alarm relay contact closes (strip connectors 31 and 32).

The regulator gives a risk of freezing alarm if the supply water temperat.
goes below the lower limit set for a free drop in the supply water or
the lower limit set for the room temperature. The present supply water
temperature appears on the display. The alarm relay contact closes
(strip connectors 31 and 32). See special maintenance settings page 30.
ALARMS:
Deviation alarm:
The regulator gives a deviation alarm if the supply water temperature
permanently deviates (factory setting 60 min) from the temp. set for it
by the regulator. (The maximum allowed deviation is listed in special
maintenance under "H1 dev. alarm" settings and the duration of the
deviation that causes the alarm to go off is under settings
"DevAlaDela", page 30.)

Measurements 3, 9, 10 and 11
as alarms:
The regulator has 2 digital inputs which can be used when transferring
an alarm if "Alarm Dig 1 (2)" has been selected in the Dig-selection.
When the switch closes, an alarm goes off and "
" appears on the
display. If an alarm has been labeled, the name of the alarm appears, for
eg., when pump 1's thermal relay is triggered, "Heat. pump err" appears
on the display. If the alarm is not labeled, "Alarm!, Dig 1 (2), Alarm
Dig1(2)” will appear on the display. In the event of an alarm, the alarm
relay contact closes (strip connectors 31 and 32).

EXTERNAL ALARMS:
Measurements 3, 9, 10, and 11 can also be used to indicate external
alarms (Potential free switch). In that case a 30k9 resistor must be
connected to the strip connector of the measurement in question.

ALARM ACKNOWLEDGEMENT:
Turn the alarm off by pressing any button. The display will return to
the mode it was in before the fault appeared or if there are additional
sensor faults their alarm information will appear on the display. If you
don't press the keyboard in 20 seconds the alarm will return to the
display if the fault has not been corrected.
The GSM modem (optional equipment) offers an economical "miniature
monitor solution”. Alarm information is directed to the desired GSM
numbers (1 and 2). See p. 39). In the event of an alarm, the regulator first
sends a text to GSM1 that indicates the cause of the alarm. The
alarm is acknowledged when the same message is sent back to the
regulator via the GSM. If the GSM1 does not acknowledge the alarm
in 5 minutes, the regulator will send the text message again to both
GSM numbers.

EH-201/L gives as alarm when a situation deviates from the norm. In
the event of an alarm, the regulator gives an alarm and a message
appears on the display. In addition, the alarm relay contact closes. Note!
Although the reason of the alarm is no more valid, the last alarm will remain
into display intil it is acknowledged. If a GSM modem has been connected
to the regulator, the alarm will appear in the desired GSM phone as a
text message. External alarms can also be connected to EH-201/L, e.g.,
leakage, network's water pressure, etc. (alarm labeling is done using the
text editor). If meas. 9 is reserved for exhaust measurement, the
regulator gives an alarm if the exhaust temperature is too high or too
low. (see p. 33)
When the contact is open
"1" appears on the display.
When the switch closes,
an alarm goes off and the
