2 About flexotron®800
flexotron®800 series comprises three model sizes: 8, 15 or 28 in-/outputs.
In each model of flexotron®800, all applications are loaded in a separate memory area.
All configuration and normal handling can be done using the display and buttons or
using the configuration tool CASE flexotron®, installed on a PC and connected via a
communication cable.
The controllers are available with or without front panel display and buttons. For units
without front panel display and buttons a separate, cable-connected terminal RDB800
with display and buttons is available.
By connecting one/two expansion controllers to port two on these units, it is possible to
increase the number of inputs and outputs. The two-port flexotron®800 models are
available only on request. For more detailed information, see chapter 17.
2.1 Application choice
On delivery, the main memory of the flexotron®800 controller is empty. All the
application programs are located in a separate memory area.
On the first start-up, the controller will start a special program for downloading a

2.3 Ventilation application
The temperature controller is based on a supply air PI-controller for heating control with
a pre-programmed set of control modes. A number of different control functions as well
as analogue and digital in- and output functions can be bound to this controller. The
choice of which functions are to be used is free, the only restriction is the physical
number of inputs and outputs of the different models.
The flexotron®800 are designed for DIN-rail mounting.
The program for an air handling unit contains, apart from other things, the following
functions:
Different temperature control modes
Supply air temperature control, with or without outdoor temperature compensation
Room temperature control (cascade controller).
Extract air temperature control (cascade controller).
Seasonal switching between supply air temperature control and room/extract air
temperature control.
Extra, separate temperature control circuit for after-heaters etc.
With control of:
Heat exchanger (Liquid connected- , plate- or rotating) or mixing dampers.
Heating coil; Water with frost protection or electric.
Chiller: Water-heated or DX in up to three steps.
Circulation pumps heating, cooling, exchanger.
Fan control
1- or 2-speed supply air fans and extract air fans.
Frequency controlled supply and extract air fans with pressure or flow control, manual
control or external control from a VAV system. Pressure controlled supply air fan with
slave connected extract air fan (output dependent or flow dependent).
Humidity control
Either humidification or dehumidification, or both humidification and dehumidification.
Timer control
For starting and stopping the unit. Up to five timer outputs for control of external
functions such as lighting, doorlocks etc.
Demand control
In buildings with strongly varying occupancy the fan speeds or mixing dampers can be
controlled by the air quality measured by a CO2/VOC sensor.

Support control
When using the control function room control or extract air temperature control, it is
possible to utilise support-heating and/or support-cooling. Minimum running time is
settable 0…720 minutes. (factory setting 20 minutes).
Free cooling
The function is used during the summer to cool the building during the night using cool
outdoor air thereby reducing the need to run chillers during the day. The function can
also be activated during daytime if the temperature so allows.
Enthalpy control for free cooling/heating
This function is used to override the mixing damper to increasing recirculation
depending on the result of the enthalpy calculation.
Cooling recovery
If the extract air is colder than the outdoor air and cooling is required, the heat
exchanger control is reversed in order to return the cool extract air. This function also
activates the heating function ‘‘Free heating’’ (see section titled ‘‘Free heating’’ below).
Free heating
If the extract air is cooler than the outdoor air and heating is required, outdoor air will
primarily be used.
Recirculation control
Recirculation of air using a supply air fan and recirculation damper, with or without
temperature control.
Pretreatment
Preheating or precooling of the intake air via an underground intake channel.
Step controllers Heating/Cooling
As an alternative to the analogue control of ’’Actuator heating Y1’’ or ’’Actuator cooling
Y3’’, step controllers can be used to control heating or cooling in steps using digital
control.

3.2 Wiring At the end of this section are terminal assignment plans that show the available factory
setting configurations. There are also empty wiring diagrams. Since the function of most
of the inputs and outputs depends on the programming of the unit the final wiring
diagram cannot be filled in until the installer has decided how to use the inputs/outputs.
It is important to make sure that the wiring is correctly done and in accordance with the
instructions given in this manual.
3.3 Supply voltage
24 V ~±15%, 50…60 Hz or 20…36 V =
If the controller flexotron®800 and the actuators connected to it share the same
transformer it is essential that the same transformer-pole is used as reference for all
the equipment. Failure to do so will prevent the equipment from functioning as
intended and may also lead to damages.
3.3.1 Inputs and outputs
The list of input and output functions in section 3.2.3 is a handy instrument to help you
keep track of which inputs and outputs you will need to configure.
Analogue inputs
Analogue inputs must refer to an protective earth terminal placed in the same terminal
block as the input being wired.
Analogue inputs can, depending on the configuration, be used for either Ni1000
temperature sensors or for 0…10 V DC analogue input signals, for example from a
pressure transmitter.
Digital inputs
Digital inputs must refer on terminal +24 V. Digital inputs may only be wired to voltage-
free contacts. Any external voltage applied to a digital input may harm the unit. The
input signal can be set to either NO or NC.
Universal inputs
A universal input can be configured to act as either an analogue input or as a digital
input.
A universal input configured as an analogue input can, depending on the configuration,
be used for either Ni1000 temperature sensors or for 0…10 V DC analogue input
signals, for example from a pressure transmitter.
Universal inputs configured as an analogue input must refer to an protective earth
terminal placed in the same terminal block as the input being wired.
A universal input configured as a digital input must, just like other digital inputs refer to
terminal +24V. It may only be wired to voltage-free contacts.

Sauter flexotron®800
ventilation
Installation and wiring
P100012082

Analogue outputs
Analogue outputs must refer to the Masse- terminal placed in the AO terminal block.
All analogue outputs can be individually set to any one of the following signals:
0…10 V DC
2…10 V DC
10…0 V DC
10…2 V DC
If the controller flexotron®800 and the actuators connected to it share the same
transformer it is essential that the same transformer-pole is used as reference for all
the equipment. Failure to do so will prevent the equipment from functioning as
intended and may also lead to damages.
Digital outputs
Digital outputs should normally refer on terminal 42 LS. Terminal 42 LSis internally
connected on terminal LS and supplies 24 V ~ or 24 V = depending on the choice of
supply voltage.
All the digital outputs are controlled by MOSFET transistors. The outputs are internally
connected with LS and can deliver max 2 A per output. However, the total power for all
the DOs must not be over 8 A.
A number of different wiring alternatives are possible depending on the type of supply
voltage to the controller flexotron®800 and the relay type.
24 V ~ supply and 24 V ~ relays
24 V = supply and 24 V = relays
