Product Usage Instructions

General Notes
Read these instructions carefully before installation and commissioning to ensure correct use! The unit may only be operated in the manner described. Any use under other conditions is notpermitted and excludes liability for any resulting damage. The appliance may only be operated with the accessories recommended in this manual. The unit may only be cleaned when closed with a dry cloth.

Meaning of the Symbols
Safety instructions are highlighted by a warning triangle and, depending on the degree of danger, are displayed as follows:

• Attention! General danger zone. Death, serious bodily injury, or considerable damage to property can occur if appropriate precautions are not taken!
• Danger from electric current: Warning of dangerous voltage or current.

Application
The electronic Basicline H/E room thermostat is designed for use in dry closed areas to regulate heating equipment based on room temperature.

Function

1. The internal or external temperature sensor measures the room temperature. The rotary button 1 is used to set the desired room temperature to a value within the range 5 °C to 30 °C (scale-digits 1-6).
2. The internal light-emitting diode 2 indicates that the heating is switched on.
3. An energy saving input allows the setpoint to be lowered using a suitable control device (clock thermostat) or an external clock.

Heating
The output is triggered when the room temperature falls below the set setpoint. The active lowering reduces the setpoint by approximately 2 K.

Installation and Electrical Connection

ATTENTION: Connection errors can cause damage to the automatic control device!
ATTENTION: No responsibility will be taken for any damage resulting from the incorrect connection and/or improper use!
DANGER: The connection of the control unit requires that an all-pole switch/circuit breaker is available in the building installation It must be marked as a disconnecting device for the unit. This switch must be suitably located and easily accessible to the user. Before working on the unit, switch off all poles of the cables.

• Only authorized trained personnel may make the connection and perform service!
• Devices with safety extra-low voltage (SELV) must not be connected.
• The connection must be made using the accompanying block diagram.
• The same phase must be used for the power supply (terminal 3) and the lowering (terminal 6).
• The device is designed only for connection to permanent wiring in dry closed areas.
• The VDE 0100 and the regulations of the local power utility company must be observed.
• The automatic control device must be installed so that it measures the average room temperature (avoid the vicinity of inlet and outlet channels, windows and doors). Install on interior walls approximately 1.3 to 1.5 m above the floor (avoid direct sunshine).

If the device does not function, first check the correct connection and the power supply.

External sensor (optional)

ATTENTION : Only RFK 133/4 or RFW 103 sensors may be used.

DANGER : The sensor line is live line voltaged. Double insulation / dielectric strength up to 3 kV must therefore be used! The installation notes are to be observed.

• To avoid interference, the sensor wire should not be laid together with other conducting wires.
• If the external sensor is used as a floor sensor, it must be installed in a conduit. If an open conduit is used, this must be closed with plugs to prevent any tile cement or screed from entering the conduit.

Changeover of the Internal/External Temperature Sensor
With the slide switch S1 ➃ in the device allows the selection of the internal or external temperature sensor to measure the room temperature. The internal temperature sensor is active as default factory setting (switch at the position as shown in the opposite drawing).If the temperature is to be measured with the external sensor RFK 133/4 or RFW 103 (please order separately), then the switch position must be activated “1”. The external sensor must be connected to terminals 7 and 8 (as shown in the connection diagram).
