otechnical wiring regulations (TABs) issued by the regional
electricity providers
Protect the products from any moisture during installation. Check the use
with Kampmann GmbH in case of any doubt. Any use other than the use
specified above is deemed not to be correct and proper. The operator of
the unit is solely responsible for any damage arising as a result of this.
Intended use is deemed to include observing the installation instructions
described in these instructions.
Modifications to the Unit
Do not undertake any modifications, conversions or additions to the control
unit or attachment parts without discussing them with the manufacturer as
they could impair the safety and operation of the unit. Do not carry out any
measures on the unit not described in this manual. Make sure that on-site
systems and cabling are suitable for connection to the intended system!

4 Operation of the Climate Controller
The Kampmann Climate Controller is a control unit with a high-quality glass
surface for the control of secondary air equipment with EC fans and 2- or
4-pipe systems.
The timer program with 3 channels and 4 changeover points allows the user
to adjust the room temperature control on demand.
Product features:
•2.5” LCD display
•High-quality glass surface with capacitive keys
•LED ring acts as key feedback
•Selection of the value to be displayed (room temperature, setpoint,
setpoint offset)
•Automatic LED background lighting
•Integrated NTC temperature sensor for room temperature control
•Standby mode
•Eco/day changeover
•Manual or automatic mode
•Functional display
•Alarm display
•Filter message appears on the display
•Timer program with 3-time channels, each with 4 switchover points
•German and english language
•Modbus interfaces (only with type 148943 and type 148944)
4.1 Operation and Display Elements
The Climate control is operated using keys (5) to (9). These keys are used to
change fan stages/automatic mode, temperature setpoints and operating
conditions.
The user menu can be accessed by simultaneously pressing keys (5), (7) and
(8) for 3s. You can set the time and date and parametrise timer programs in
this menu (see chapter 7).
Special system requirements can be configured in the password-protected
expert menu (see chapter 8). The following system requirements are
available:
•Display
•Lock operating functions
•Type of setpoint setting
•Inputs and outputs
•Sensor calibration
•Control and regulation parameters

5 Functionality of the Climate Controller
5.1 General
The type number of the Climate Controller is displayed on the start screen.
The Climate Controller can be switched on and off using the On/Off key (9).
In this mode, the display is switched off and the controller is disabled. Only
the protection functions (unit frost protection, room frost protection, heat
protection) remain enabled. This function is not enabled when using the key
card function.
The ring LED gives feedback each time a button is pressed. The main screen
is displayed if no key is pressed for 3 seconds.
The key fields of the Climate Controller are calibrated as soon as
mains power is applied. Therefore the user interface should not be
touched for 60s after voltage has been connected.
5.2 Fan Control
The EC fan is controlled by the 0-10 V output of the Climate Controller.
Manual fan stages and/or Automatic mode can be adjusted using keys (7)
and (8). A user-set speed is overwritten by the timer channel at the start of a
new timer channel segment. The speed increment between the individual
stages depending on the number of fan stages set up:
1 stage: 100% increment
2 stages: 50% increments
3 stages: 33% increments
4 stages: 25% increments
5 stages: 20% increments (default setting)
The fan is actuated for 1s at maximum speed to ensure the safe
start-up of the fan.
5.3 Temperature Control
The Climate Controller has an internal temperature sensor, which is used by
default for temperature control. Optionally, input 1 can be configured with an
external temperature sensor. In this case, this measured value is automatically
the basis for temperature control.

5.3.1 Temperature control in 4-pipe mode
In 4-pipe mode, the controller automatically specifies the operating mode
based on the room temperature and the setpoint inputted. The parameters:
•Neutr. zone 4-p
•Valve hysteresis
•Nat. convection heating
•Nat. convection cooling
are used to define the properties of the room temperature control.
The parameter Neutr. zone 4-p is used to define the setpoint value for heating
and cooling mode. The corresponding valve is controlled depending on this
value and the hysteresis valve parameter. The fan is controlled depending on
the neutral zone and natural convection. The control voltage for the fan is
calculated on the basis of the P-band as well as the minimum and maximum
speed of the fan.
The Climate Controller is factory-configured as a 2-pipe unit
(Heating). The inputs and outputs need to be adapted if the unit is
a 4-pipe system.
Input 1: no function
Input 2: no function
Output 1: Cooling
Output 2: Heating
If ECO mode is enabled in heating mode, the heating setpoint is lowered by
the ECO setback parameter.
If ECO mode is enabled in cooling mode, the cooling setpoint is raised by the
ECO rise parameter.
