Description: ROTH ROOM THERMOSTAT RSF 55.T/2
Application
1.
The electronic RSF 55.T/2 room thermostat for the room temperature-
dependent regulating of heating and cooling equipment is designed for use in
dry closed areas.
Function
2.
The internal temperature
measures the room temperature. The
À
rotary button is used to set the
desired room temperature to a value
within the range 5° C to 30° C. The
Á
light-emitting diodes indicate that
the heating / cooling is switched on.
An input (c/o signal) allows the
change to cooling mode
connecting A-potential (24V).
An energy saving input allows the
setpoint to be lowered (heating mode)
or increased (cooling mode) using a suitable control device (RSF 220.T/2) or
an external clock.
Temperature range
scale-digits 1
temperature 5°C
Heating
2.1
The output is triggered when the room temperature falls below the setpoint,
indicated by a red LED. The active lowering reduces the setpoint by
approximately 2 K.
Cooling
2.2
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.
Optionally a dewpoint sensor can be connected. If condensation occurs the
thermostat switches the output off and the blue LED flashes.
Installation — only by authorized trained personnel

Warning: 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 device must be disconnected from the mains before any work is done on it.
− Only authorized trained personnel may make the connection and perform
service!
− The connection must be made using the accompanying block diagram.
− The same A-potential must be used for the power supply (terminal 3),
the c/o- signal (terminal 1) and the lowering / increasing (terminal 5).
− The device is designed only for connection to permanent wiring in dry
closed areas.
− The VDE 0100, EN 60730 (Part 1) 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.
3.1 Changeover with / without dewpoint sensor
Ã
Plug-in jumper JP1 in the
device allows the selection if the
thermostat works with or without
dewpoint sensor.
The dewpoint sensor is inactive as
default factory setting (jumper
plugged in at the bottom as shown
in the opposite drawing).
If the external dewpoint sensor
shall be used, then the jumper
must be plugged in at the top.
Currentless closed (NC) or currentless open (NO) actuators
3.2
Â
Plug-in jumper JP2 in the device allows the selection of
currentless closed or currentless open actuators.
The default factory setting is for currentless closed
actuators (jumper plugged in at the top as shown in the
opposite drawing).

3.3 Limiting the range
If the complete setpoint range of the rotary button is not to be used, it is
possible to mechanically limit this range.
First remove the rotary button. Turn the rotary button to a position that will
later lie within the limited range. Mark this position. Use a screwdriver to
raise the rotary button at the opening opposite the marking.
Note: The rotary button may only be removed once!
Remove the two riders from the lower part
of the housing (see the following diagram).
Insert these riders with the narrow edge at
the bottom in the openings located below
the button.
Orient yourself on the visible scale when
you insert the upper and lower rider.
Finally, the button must be replaced at the
original position.
Note: Ensure that you replace the button at
this position, otherwise the scale will not
match.
