Room thermostat Basicline H/C 24 V
manual
1. 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 not permitted 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.
2. 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.
3. Application
The electronic Basicline H/C 24 V room thermostat for the room temperature
independent regulating of heating and cooling equipment is designed for use in dry
closed areas.
4. Function
The internal temperature sensor measures the
room temperature. The rotary button  is used
to set the desired room temperature to a value
within the range 5 °C to 30 °C (scale-digits 1-6).
The internal light-emitting diodes  indicate that
the heating/cooling is switched on.
An input (c/o signal) allows the change to cooling
mode by connecting L1-potential (24 V AC).
An energy saving input allows the setpoint to be
lowered (heating mode) or increased (cooling
mode) using a suitable control device (clock
thermostat) or an external clock.
4.1 Heating
The output is triggered when the room temperature falls below the set setpoint,
indicated by a red LED. The active lowering reduces the setpoint by approximately
2 K.
4.2 Cooling
The output is triggered when the room temperature rises above the setpoint,
indicated by a blue LED. The active increasing rises the setpoint by approximately
2 K.
The surface to be cooled can be monitored for condensation using an optionally
connectable dewpoint sensor. If condensation occurs, cooling is interrupted and
the blue LED  flashes.
5. Installation — only by authorized trained personnel
Only authorized trained personnel may make the connection and perform
service!
Connection errors can cause damage to the automatic control device!
No responsibility will be taken for any damage resulting from the incorrect
connection and/or improper use!
The connection of the control unit requires that an allpoleswitch /
circuitbreaker 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.
>
The device is designed only for connection to permanent wiring in dry closed
areas.
>
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.
>
The VDE 0100 and the regulations of the local power utility company must be
observed.
>
Devices with 230 V voltage must not be connected to the Basicline H/C 24 V
thermostat.
>
The connection must be made using the accompanying block diagram.
>
The same phase (L1) must be used for the power supply (terminal 3), the
c/o-signal (terminal 1) and the lowering / increasing (terminal 6).
If the device does not function, first check the correct connection and the power
supply.

5.1 Cooling lock function
The slide switch S2 in the device allows the
selection whether the cooling mode is
deactivated.
The default factory setting is activated
cooling mode (switch position is at "0" as
shown in the opposite drawing).
5.2 Changeover with/without dewpoint
sensor
The slide switch S1 in the device allows
the selection if the thermostat works with
or without dewpoint sensor.
The dewpoint sensor is inactive as default
factory setting (switch at the position
shown in the opposite drawing).
If the external dewpoint sensor RFTP1
(Mat.-Nr. 1135006688)
separately) shall be used, then the slide
switch must be moved to the right. The
external dewpoint sensor
connected to terminals 7 and 8 (as shown
in the connection diagram).
