6.4.4.2 COOLING FUNCTION
COOLING output can be control within COOLING PARAMETERS PAGE;
COOLING PARAMETERS PAGE CONTROL parameter is used to select control mode.
If the COOLING PARAMETERS PAGE CONTROL parameter is PROPORTION then control mode is
PROPORTIONAL, if the parameter is ON/OFF then control mode is ON/OFF, if the parameter is NONE
then process output will be zero.
1. ON- OFF CONTROL MODE
COOLING output will be switched on as soon as the Temperature(NOTE1) becomes higher than the
settemp(NOTE2) plus COOLING PARAMETERS PAGE HYST. COOLING output will be switched off as soon
as Temperature(NOTE1) is equal to or lower than settemp(NOTE2). COOLING PARAMETERS PAGE
PERIOD parameter is used to prevent unnecessary switched on and off. COOLING output will remain on or
off minimum COOLING PARAMETERS PAGE PERIOD parameter value.
NOTE1:
If COOLING PARAMETERS PAGE SENSOR parameter is ROOM1;
Temperature = ROOM1 sensor’s temperature,
If COOLING PARAMETERS PAGE SENSOR parameter is ROOM2;
Temperature = ROOM2 sensor’s temperature,
If COOLING PARAMETERS PAGE SENSOR parameter is ROOM1&2;
Temperature =( ROOM1 sensor’s temperature + ROOM2 sensor’s temperature) / 2.
NOTE2:
If COOLING PARAMETERS PAGE SET POINT is RELATIVE and if curve is enabled;
Settemp= HOUSE TEMP from curve + SET VALUES PAGE TEMP.COOL +
COOLING PARAMETERS PAGE OFFSET,
If COOLING PARAMETERS PAGE SET POINT is RELATIVE and if curve is disabled;
Settemp= SET VALUES PAGE TEMP.HOUSE + SET VALUES PAGE TEMP.COOL +
COOLING PARAMETERS PAGE OFFSET,
If COOLING PARAMETERS PAGE SET POINT is ABSOLUTE;
Settemp= SET VALUES PAGE TEMP.COOL + COOLING PARAMETERS PAGE OFFSET.
