CONTROLS
DUPLEX-S units are delivered with basic control components
or with complete control systems.
•selection of the most suitable and efficient control system
at the lowest cost, depending on the particular application
There are two types of control systems available (electric,
digital) according to customer needs and application.
•control system is integrated with the unit, most components
are already wired and checked in factory, thus reducing the
The systems also include variety of sensors (temperature,
risk of incorect wiring
humidity, air quality, CO ) for effective operation control.

•no control system project documentation is necessary
for standard cases, standardized solutions can be used
•simple wiring, system simplicity, error indication
•qualified technical support and consulting

Simplified diagrams of electrical wiring
„A“ – basic
„B“ – electric
OPS
– all electrical components are wired
to a junction box terminal strip
inside or outside the unit
– standard components are fans,
damper actuators, capillary freeze
protection thermostat of hot water
heating coil
– more components is included upon
customer's request (exact
actuator type, sensors,
thermostats, pressure switches
etc.)
– simple system
– two-speed fan control (MIN, MAX)
(exact volume flow rate can
individually be set for each fan
during commissioning)
– on/off control of by-pass and
mixing damper
– on/off remote control of heating
coil: temperature is set on the
thermostatic valve of hot water coil
or directly on the electric coil
– suitable for applications
with separate delivery of
control system; e.g. large
buildings with central
control system etc.
– electric system is suitable
for simple applications
(e.g. ventilation of locker
rooms, gyms, restaurants
etc.)
– it cannot be used for units
with cooling coil
– it is recommended for
applications with air reheat
only (not for warm-air
heating)

basic control
–
control system designed
specially
for effective control of kitchens
– consist of SM microprocessor
module fitted into kitchen hood
or ventilation ceiling, OP control
panel and RG junction board
– control principle consists
of automatic setting of volume flow
rate depending on heat production
of kitchen appliances (i.e. difference
of temperatures under the kitchen
hood and in the space)
„E“ – DC-series
digital control
– A comfort control system for
DUPLEX units
– A programmable module software
designed especially for DUPLEX
units
– Supply and exhaust fan speed
control
– Controlling supply or room
temperatures
– Optional control of a water and
electric heating coil
– Optional water and direct cooling
– Heat pump performance control
– Automatic control of by-pass and
– Suitable for comfort
applications
– Optional fully automatic
operation of the unit via a daily
or weekly programme
– Possibility to connect air
quality, Co concentration and

relative humidity sensors etc.
– Optional performance control
via a 0-10 V signal from a
higher-ranking system
– Connectable to central
control systems using
expansion cards (KNX,
Modbus, ...)
– Settings can be done using
