2 Introduction to flexotron®400
2.1 flexotron®400 controllers
The controller flexotron®400 is a range of pre-programmed, configurable
controllers that can be set to handle everything from temperature control or
humidity control to CO2 control or pressure control.
RDT405 and RDT 410
The flexotron®400 series comprises two different types, RDT405 and RDT410.
The RDT405 has 5 inputs/outputs and can be configured to control Temperature,
CO2, Humidity or Pressure. There is a new analogue input for connection of an
external Ni1000 setpoint device for control mode 1 (Temperature control).
The RDT410 has 10 inputs/outputs and can be configured to control
Temperature (ventilation control with heating and cooling), Water-heated radiator
heating with outdoor temperature dependent control-curve or Domestic hot-water
control. There is a new analogue input for connection of an external Ni1000
setpoint device for control modes 1…4. The RDT410 is available in two versions,
RDT410F201 with 24 V AC supply voltage and RDT410F201 with 230 V AC
supply voltage.
Mounting
The controllers flexotron®400 are designed primarily for DIN-rail mounting but
can also be screw-mounted to any suitable surface.
flexotron®400 - RDT410
The RDT410 is a pre-programmed, configurable controller. All configuration and
normal handling is done using the display and the knob on the front.

4 Installation and wiring
4.1 Installation
The RDT410 is intended to be installed and handled by professional personnel.
The installation should conform to the requirements of installation category 3 and
pollution degree 2.
There are a number of mounting alternatives:
- DIN-standard casing (minimum 7 modules)
- Cabinet, either on a DIN-rail or, using the two screw-pockets provided, by
being screwed to any suitable flat surface in the cabinet
- The controller can also be mounted in a cabinet door or other control panel,
using a suitable front-mounting kit
For installations which are connected to 230 V AC:
- Observe that there is a risk of electric shock on contact with terminals L, N
and 17…19.
- Mount the RDT410 in a DIN-casing or similar where it can be used without
risk of electric shock. The casing should provide at least 6 mm insulation
from connected cables and terminals 1-3 and 10-12.
- The RDT410 should be protected against overload by a fuse in the
installation. Since the maximum load is 1000 VA, a fuse of 6 A is suitable.
- Circuit breaker and fuse: The controller should be connected to a circuit
breaker so the power supply to the controller can be cut. Place this breaker
close to the controller where it is easy for the operator to reach. It should be
clearly marked as a circuit breaker for the controller.
4.2 Wiring
This section only describes general rules and technical limitations concerning the
wiring.
In chapter 5 there are specific wiring diagrams for the different control modes.
Choose the one suitable for the application on hand.
It is important to make sure that the wiring is correctly done, in accordance with
the instructions given in this manual and in accordance with local legislation for
this type of installation.

If the RDT410 (24V supply model only) and actuators connected to it share
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.

4.2.2 Inputs and outputs
All ground terminals are interconnected and also connected to G0.
Analogue inputs AI
The analogue inputs must refer to an ground terminal. AI1 and AI2 are for Ni 1000
temperature sensors only. AI1 has a temperature range of 0…84°C. AI2 has a
temperature range of
-30…+54°C. SPI is only intended for a Ni1000 setpoint device, the range is
0...40°C.
Digital inputs DI
The digital inputs must refer to DI+ on terminal 2. The digital inputs may only be
wired to voltage-free contacts. Any external voltage applied to a digital input may
harm the unit.
Universal input UI
The universal input can, depending on the choice of application, be made to act
as either an analogue input or as a digital input.
When used as an analogue input it is for Ni1000 temperature sensors. The input
then has a range of 0…+84°C
UI must refer to UI+ on terminal 4.
Analogue outputs
Analogue outputs must refer to a ground terminal or directly to G0.
If the RDT410 (24V supply model only) and actuators connected to it share
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
The two digital outputs DO1 (terminal 15) and DO2 (terminal 14) are triac
controlled. The triacs are internally connected to G0. Each triac can handle 24 V
AC, 500 mA. The outputs cannot be used to drive DC relays.
When DO1 and DO2 are used for 3-point control DO1 will always be increase
signal (open valve) and DO2 always decrease signal (close valve)
The outputs should normally refer to GDO on terminal 16. GDO is internally
connected to LS and supplies 24 V AC.
In RDT410 GDO can deliver the necessary 2 x 300 mA.
In RDT410F301 however, the internal transformer’s capacity restricts the current
on GDO to approx. 165 mA.
