default
0
This configuration variable specifies the time the fan runs before the
outputs are switched ON. It is typically used for electric heat outputs
with fan interlock (see nciFcuConfig.fan_interlock_0 and _1). The
interlock must be set.
0
This configuration variable specifies the time the fan still runs after the
control algorithm has turned OFF the cooling/heating outputs. It is
typically used for electric heat with fan interlock (see
nciFcuConfig.fan_interlock_0 and _1). The interlock must be set. In
case of smoke purge the overrun-time will be ignored.
5%
This is the switching level to turn ON stage 1 of the cooling equipment
(if configured as multistage).
50%
This is the switching level to turn ON stage 2 of the cooling equipment
(if configured as multistage).
75%
This is the switching level to turn ON stage 3 of the cooling equipment
(if configured as multistage).
5%
This is the switching level to turn ON stage 1 of the heating equipment
(if configured as multistage).
50%
This is the switching level to turn ON stage 2 of the heating equipment
(if configured as multistage).
75%
This is the switching level to turn ON stage 3 of the heating equipment
(if configured as multistage).
10%
This configuration variable applies only to cool outputs configured as
multistage outputs and specifies the hysteresis between switching the
cool stages ON and OFF.
10%
This configuration variable applies only to heat outputs configured as
multistage outputs and specifies the hysteresis between switching the
heat stages ON and OFF.
100%
This configuration variable specifies the switch-over control output level
for the reheat output.
