Note
: The HEATING section has been parameterized following the “Hysteresis
control method”, while the COOLING one has been parameterized following
the “PI Control method”.
However, both control methods can be used in either zone.
HEATING
CONTROL METHOD Æ To choose between “Hysteresis” or
“PI Control” method
¾ Upper Hysteresis (tenths of a degree):
This parameter sets
the upper hysteresis point referred to the “Set Temperature”
¾ Lower Hysteresis(tenths of a degree): This parameter sets the
lower hysteresis point referred to the “Set Temperature”
ADDITIONAL HEATING 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
heating system.
It is when a user relays on one of this auxiliary systems, (A/C split, Heat
Pump…) 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.
¾ Additional Heating Band:
As mentioned before, the extra
heating contribution must be complementary to the Heating
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.
