1. Safety Information
1.1. Mounting and electrical installation may only be carried
out by a qualified electrician. Instructions supplied by the
manufacturer or dealer must be followed in order for the
product warranty to be effective.
1.2. The mains voltage must be disconnected during all work
with the cover removed. Otherwise, there is a risk of
electric shock.
1.3. The product must not be used with equipment other than
that specified.
1.4. The total output of the connected fan motors must not
exceed the maximum load for the controller.
2. Transport, storage
2.1. The product is suitably packed at the factory for the
agreed mode of transport.
2.2. Take care to avoid damage to the packaging or controller
when unpacking.
2.3. The original packaging must be used at all times during
storage.
2.4. Avoid exposure of the controller to extreme heat or cold.
3. General description
3.1. The controller is intended for the speed control of 1-
phase fans within voltage band II.
3.2. Adjustment is by means of a switch that selects different
voltage steps to the fan.
3.3. An illuminated warning lamp indicates that the supply
voltage to the fan is not interrupted at all terminals.
4. Technical data
Supply voltage: 230V 50-60 Hz
Output voltage: 80, 105, 130, 160, 230 V
Enclosure class: IP54
Ambient temperature: 50°C
Manufacturing standard: EN 61558-1/2-13
4.1. One terminal of the output circuit of the controller is
protected by an automatic current limiter capable of
external resetting.
4.2. With the switch in position 0, the controller is
disconnected at all terminals (not REU1,5). Relay
connection blocks are also dead in this position.
4.3. RTRE models are provided with a motor protector. The
protector can be reset by interrupting the mains voltage
for 10 seconds. RTRE also includes a room thermostat
control function, for which the terminals are connected at
the time of delivery. N.B. The indicator lamp will illuminate
to indicate a tripped motor protector and interrupted room
temperature circuit, because these only interrupt the
voltage supply to the fan at a single terminal.
4.4. The switches of the REU1,5 interrupt the voltage supply
at only a single terminal, and the indicator lamp will thus
illuminate with the switches in position 0. A circuit breaker
for disconnecting all terminals must be installed ahead of
the REU1,5 controller.
5. Installation, mounting
5.1. Wall mounting with three screws.
5.2. Note the maximum ambient temperature for the
controller.
5.3. The cover of the controller is opened by means of a
captive screw.
5.4. Two cable ducts are provided for a maximum cable
diameter of 13 mm.
5.5. The distribution box should be protected with a 10A fuse
for installation using 1,5 mm
2
conductors, and with a 16A
fuse for 2,5mm
2
conductors.
5.6. Max. load relay connection 7 A resistive / inductive.
6. Maintenance, service
6.1. The controller is essentially maintenance-free. If the
controller has been accidentally exposed to abnormal
levels of liquid, dust or physical damage, its function and
safety must be checked before further operation.
6.2. Make sure that the terminal blocks are fully tightened.
