Automatic Operation And System Operation Modes For Ppb 30 K Units - Maico PP 45 O Bedienungsanleitung

6.6 Automatic operation and system
operation modes for PPB 30 K units
These two operating modes are only available
if activated with the commissioning software
of the RLS 45 K control PPB 30 K units.
When undertaking the basic setting with
the commissioning software, your specialist
installer can select between the automatic
operation (continuously variable regulation)
or system operation (automatic regulation
when value limit is exceeded).
The automatic operation and system opera-
tion modes only affect the PPB 30 K units. All
other units on the RLS 45 K are operated as
set on the room air control.
PPB 30 automatic operation mode
In automatic mode, the PPB 30 K units run
virtually independently of the settings under-
taken on the RLS 45 K control.
Heat recovery or cross-ventilation operating
mode can be set manually. The ventilation
level Off, External Off and exhaust air mode
functions are also available (if released in the
basic setting).
Connected PPB 30 O and PP 45 units run
according to the settings on the RLS 45 K
control.
In automatic operation, the volumetric flow
regulation is always continuously variable and
undertaken using the humidity and temper-
ature values measured with the humidity
sensor inside the PPB 30 K.
Continuously variable regulation of the vol-
umetric flow takes place in a linear fashion
between the set humidity value limits of
r.h.%=min (minimum ventilation level) and
r.h.%=max (maximum ventilation level).
Measurements from other sensors only affect
the volumetric flow regulation of the PP 45
units (Fan1/Fan2 fan interface).
Dehumidification mode is possible via exhaust
air mode (45 m³/h) or intensive ventilation
(ventilation level 5).
6 Operating ventilation unit(s) | UK
Dehumidification mode starts automatically
when the maximum humidity value limit (in-
tensive ventilation) is exceeded.
The ventilation system then runs in exhaust
air mode or intensive ventilation until the val-
ue has fallen 3 % below the value limit. Then
the ventilation switches back to demand-
driven mode. For exhaust air mode  Chap-
ters 6.7 and 6.8.
The "Max. humidity value limit" parameter can
be set by your specialist installer using the
commissioning software.
PPB 30 system operation mode
In system operation, the ventilation system
(all PPB 30 K and PP 45 or PPB 30 O units)
run with all the settings undertaken on the
RLS 45 K control.
This includes heat recovery or cross-ventila-
tion, ventilation level, intermittent ventilation,
sleep function or External Off operating mode.
Demand-driven mode can be switched on and
off manually as described in Chapter 2.3.
In contrast, the way in which the system
behaves when the maximum humidity value
is exceeded is not dependent on the set op-
erating mode. The function selected for dehu-
midification (exhaust air mode or intermittent
ventilation) is always undertaken. If exhaust
air mode is switched on, all PP 45 / PPB 30
O connected to the RLS 45 K run with the
supply air function.
Humidity value limits, start delay, duration,
exhaust air mode or intensive ventilation can
be set by the specialist installer using the
commissioning software (installer lever).
If demand-driven mode is switched on, air
dehumidification with PPB 30 K units is con-
tinuously variable depending on the humidity
value. The function is always active. The air
volume is regulated in a linear fashion using
the set min/max humidity values.
