1 . USE
RCU Series are designed as an all in one product for different room
layouts such as apartments, hotel rooms, hospitals and residences.
Room Control Unit covers all requirements of the electrical installation
of room applications and offers following functions in one product.
• Switching lighting
• Switching loads
• Controlling AC/DC blinds
• Controlling fan coils (2 & 3-point valve)
• Dry contact inputs
RCU has up to 20 x 16A relay outputs. These outputs are grouped as
5/4/3/2 independent output channels for XX = 20/16/12/8 respectively.
Each channel can be configured to have different modes of operation
as follows:
• Switching output x4
• AC Blind
x2
• DC Blind
x1
• 2 Point valve
x2
• 3 point valve
x2
Suitable for switching resistive, capacitive and inductive loads as well as
fluorescent lamp loads according to EN 60 669. A single switch output
provides following functions:
• Staircase
• External logic
• Internal logic
• Priority
• Threshold
• Operating hour
• Sweep
RCU has up to 18 independent input channels. A single input channel
provides following functions:
• Switch / push button input
• Dimmer control
• Control of shutter/blinds
• Value sending
• Scene control
• Counter for count pulse
Manual control is possible for each channel through the built-in button
panel.
220V auxiliary power is NOT required.
