C7000 INSTRUCTIONS fOR A/C UNITS
Additional capacity - Humidifying (previously: Humidity)
You can have started a standby unit if the air humidity setpoint is
passed under by the zone humidity (Average value or unit humidity,
when average value determination is disabled).
As the treshold („overloadstart“) for the additional capacity is indi-
vidually set in each A/C unit, this function is essentially appropriate
for N+1 operation. Otherwise, it may happen that several units are
started simultaneously (at the same threshold value).
The undercut of the setpoint can be adjusted by the parameter in the
third line of menu H in the shape of a humidity difference. Setting "0"
disables the additional capacity function.
When the humidity rises again, the additional capacity unit is swit-
ched off with a hysteresis of 3% relative humidity.
Additional capacity - Dehumidifying
You can have started a standby unit if the air humidity setpoint is exceeded by the zone humidity (Average
value or unit humidity, when average value determination is disabled).
As the treshold („overloadstart“) for the additional capacity is individually set in each A/C unit, this function is
essentially appropriate for N+1 operation. Otherwise, it may happen that several units are started simulta-
neously (at the same threshold value).
The excess of the setpoint can be adjusted in the shape of a humidity difference. Setting "0" disables the addi-
tional capacity function.
When the humidity reduces itself, the additional capacity unit is switched off with a hysteresis of 3% relative
humidity.
Precondition:
The additional capacity unit must be set as standby unit and must be assigned to a zone. Moreover the corres-
ponding parameter (temperature or humidity) "Overload" must have a value different from zero.
