Controller
„Without
controls“
– all components with power supply are connected to a
terminal block outside the unit
–
more components are included upon customer's
request (exact actuator type, sensors, thermostats,
pressure switches etc.)
– good for applications where third party control is
supplied separately – e.g. large buildings with building
management systems
– not applicable
„RD4“ controls
Standard functions of the „RD4“ controls
– EC fan speed control (based on selected mode)
– automatic by-pass damper position (heat and cool
recovery)
– evaluates and prevents emergency limits based on
measured temperature
– ventilation and temperature weekly program setting
– standard built-in Ethernet connection for remote
internet communication
– inputs for switching using 230 V
(4 inputs – 3 delayed, 1 instantenious) – switch e.g.
from bathrooms etc.
– optional connection of CO or RH sensor
2
– max. 2 sensors with a switch or 0 – 10 V output
– outputs for electric preheater and heater control
(pulse 10 V) or hot-water control (0 – 10 V)
Additional RD-IO modules
– optional manometer connection to ensure constant
airflow control (see Constant airflow and pressure
control on previous page)
– constant pressure control
– cooling control outputs (DX- or chilled-water cooling)

„DC“ controls
Standard functions of the „DC“ controls
– EC fan speed control (based on selected mode)
– automatic by-pass damper position (heat and cool
recovery)
– evaluates and prevents emergency limits based on
measured temperature
– ventilation weekly program setting
– connection of CO or RH sensors – max. 1 sensor with

0 – 10 V output
– outputs for electric preheater and heater control
(pulse 10 V) or hot-water control (0 – 10 V)
– based on CAREL control modules
– cooling control outputs (ox or chilled water cooling)
– inputs for constant airflow control (see Constant
airflow and pressure control on previous page)
Additional communication modules
– DC-WEB – Ethernet for remote communication via
Internet or connection to a BMS via the BACnet
protocol
– DC-KNX – connection to a BMS via the KNX / EIB
protocol
– DC-RS – connection to a BMS via the Modbus
protocol – serial interface
