System, this implies, that it would be inconsistent that the
“Auxiliary” system provides heat until the “Set temperature” is
reached. It is because of this that this parameter sets the number
of degrees below the “Set Temperature” we want our “auxiliary
system” to be referred.
The real operation will be as follows
And the Auxiliary System in this case will be providing heat to the
room until its Reference Temperature is reached, to leave the Main
System acting alone from that moment.

Control Type:
To choose between “PWM (1 bit)” and
“Continuous (1 byte)” Control.

Cycle Time:
9
PWM (1bit):
This parameter it used to set a cycle period
during which it’s calculating the pulse width modulation.
9
Continous (1 byte):
This parameter set the cycle
transmission of “control variable” Object. In this case, this
variable is send after a value changing or periodically (time
defined in this area).
¾
Control Parameters:
Depending on if the system is working
with COOL or HEAT, this parameter sets the cooling or
heating system type used in the installation.
ADDITIONAL COOLING
Æ
Under normal conditions, Climatization
Systems are responsible by themselves for the global regulation of the room
temperature. However, “auxiliary systems” are more and more installed
everyday, so these systems may be used to complement the Main Cooling
System.
It is when a user relays on one of these auxiliary systems, when this parameter
has a major importance. Enabling this field, the auxiliary system is asked to
contribute to reach the “Set Temperature” as soon as possible.

Additional Cooling Band:
As mentioned before, the extra
cooling contribution must be complementary to the Main
Cooling System, this implies, that it would be inconsistent that
