Number of Fan Speeds
[
2
/ 3
]: sets how many fan speed levels are
implemented in the HVAC unit.
Fan Mode
[
Auto
/
Manual
/
Auto + Manual
]. The behaviour and parameters of
each option are explained in the following sections:
➢
Fan Mode After ETS Download:
[
Auto
/
Manual
].
➢
Auto / Manual Switch Object
[
0 = Auto; 1 = Manual
/
0 = Manual; 1 =
Auto
]: sets the particular values that will switch from one control mode to
the other, if received through object “
[Unit x] Fan: Auto / Manual
”. The
object “
[Unit x] Fan: Auto / Manual (Status)
” will save the value of the
active mode.
Weight Factor in Zone i
[
0…
1
…99
]: influence which each zone will have
when calculating the fan speed automatically. This value can be change
through the object
“
[Group n] [Gi] Weight Factor
”. (Only enabled with
automatic fan mode
.)
Force MIN Fan Speed if nº of Open Grilles is Less than or Equal to
[
0…
1
…12
]:
sets the minimum number of grilles (minus one) that must remain
open before the fan speed can be set to levels greater than the minimum.
The value “0” disables this function. (Only enabled with
manual fan mode
.)
Force MED Fan Speed if nº of Open Grilles is Less than or Equal to
[
0…
1
…12
]: sets the minimum number of grilles (minus one) that must remain
open before the fan speed can be set to levels greater than the intermediate.
The value “0” disables this function. This is only available for three-level
configurations. (Only enabled with
manual fan mode
.)

TEMPERATURE SETPOINT
The global temperature setpoint (T
GSP
, i.e., the temperature setpoint to be sent to the
HVAC unit) takes into account the different local setpoints (T
LSPi
) from the zones that
make up its group, the reference temperature of each zone (T
REFi
), the return
temperature (T
RET
) and the active mode. This calculation consists in:
Heating Mode:
T
GSP
= T
RET
+ Max (0, RInt (Max(T
LSPi
− T
REFi
)))
