5.- Fan regulation
Fans can be controlled ON/OFF or via a 4-20 mA signal by means of a inverter.
5.1.- MANAGEMENT OF ON/OFF FANS (CONF_5=0).
The parameter
COND_4
defines the type of regulation for fans controlled ON/OFF.
NEUTRAL ZONE (COND_4=0):
Five operating zones are defined.
Pcond (bar)
Tcond (ºC)
COND_7
COND_5
COND_1 (COND SP)
COND_6
COND_8
POSITIVE FAST ZONE
POSITIVE SLOW ZONE
NEUTRAL ZONE
NEGATIVE SLOW ZONE
NEGATIVE FAST ZONE
The parameters which delimit each of the 5 zones (
COND_5, COND_6, COND_7 and COND_8
) are
defined in
bar
or
ºC
according to the parameter
CONF_8
(only in
bar
in the case that CONF_7 = GENERIC).
The control action depends on the discharge probe reading in the following way:
Within the NEUTRAL ZONE:
No action is carried out on the fans (fans are neither started
nor stopped).
Within the POSITIVE SLOW ZONE:
Fans are started in a time period defined by the
parameter
TEMP_3.
Within the POSITIVE FAST ZONE:
Fans are started in a time period defined by the
parameter
TEMP_5.
Within the NEGATIVE SLOW ZONE:
Fans are stopped in a time period defined by the
parameter
TEMP_4.
Within the NEGATIVE FAST ZONE:
Fans are stopped in a time period defined by the
parameter
TEMP_6.
