EMKO EPC-3 - Alarm Conditions and Specific Types; Differential Alarm Situations; Specific Alarm Types

Third situation:
If Temperature(NOTE1) is higher than ALARM SET VALUES ABSOLUTE MAX plus
ALARM SET VALUES DIFFERENTIAL for more than a minute ALARM STATUS 1 DIFFERENTIAL alarm
is switched ON.

NOTE1:
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM1;
Temperature = ROOM1 sensor’s temperature,
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM2;
Temperature = ROOM2 sensor’s temperature,
If VENTIL. PARAMETERS PAGE SENSOR parameter is ROOM1&2;
Temperature =( ROOM1 sensor’s temperature + ROOM2 sensor’s temperature) / 2.
NOTE2:
If curve is enabled;
Settemp= HOUSE TEMP from curve.
Min.Vent= MIN. VENT from curve.

4. ALARM1 alarm
If ALARM1 input is ON then ALARM STATUS 1 alarm is switched ON.
5. NEGATIVE PRESSURE alarm
As long as INFLUENCE 2 PAGE NEG PRESSURE parameter is different from NON, negative pressure input
is enabled. Otherwise negative pressure input is disabled.

6. HUMIDITY alarm
If HUMIDITY sensor is broken while EPC is working then ALARM STATUS 1 HUMIDITY alarm is switched
ON.
Fourth situation:
If Temperature(NOTE1) is lower than Settemp(NOTE2) minus ALARM SET VALUES DIFFERENTIAL
for more than a minute ALARM STATUS 1 DIFFERENTIAL alarm is switched ON.
