2. PROPORTIONAL CONTROL MODE
If the Temperature(NOTE1) is lower than settemp(NOTE2) minus HEATING2 PARAMETERS PAGE HYST
control will be continuously on. If the Temperature(NOTE1) is higher than the settemp(NOTE2) then, control
will be continuously off. If the measured temperature(NOTE1) is between settemp(NOTE2) and
settemp(NOTE2) minus HEATING2 PARAMETERS PAGE HYST then, control output will be on for a portion
of the HEATING2 PARAMETERS PAGE PERIOD.
Process Output rises from 0% to 100% in
HEATING2 PARAMETERS PAGE PROP RAMP period.
This feature is called output filter.
If HEATING2 PARAMETERS PAGE PROP RAMP is zero then
output filter is off.
NOTE1:
If HEATING2 PARAMETERS PAGE SENSOR parameter is ROOM1;
Temperature = ROOM1 sensor’s temperature,
If HEATING2 PARAMETERS PAGE SENSOR parameter is ROOM2;
Temperature = ROOM2 sensor’s temperature,
If HEATING2 PARAMETERS PAGE SENSOR parameter is ROOM1&2;
Temperature =( ROOM1 sensor’s temperature + ROOM2 sensor’s temperature) / 2.
NOTE2:
If HEATING2 PARAMETERS PAGE SET POINT is RELATIVE and if curve is enabled;
Settemp= HOUSE TEMP from curve + SET VALUES PAGE TEMP.HEAT +
HEATING2 PARAMETERS PAGE OFFSET,
If HEATING2 PARAMETERS PAGE SET POINT is RELATIVE and if curve is disabled;
Settemp= SET VALUES PAGE TEMP.HOUSE + SET VALUES PAGE TEMP.HEAT +
HEATING2 PARAMETERS PAGE OFFSET,
If HEATING2 PARAMETERS PAGE SET POINT is ABSOLUTE;
Settemp= SET VALUES PAGE TEMP.HEAT + HEATING2 PARAMETERS PAGE OFFSET.
