The radio room thermostat for the individual regulation of underfloor heating and electric
radiators. The DuoFern room thermostat 2 9433-1 (2nd generation) automatically measures and
controls the room temperature of individual rooms for example by controlling a radiator
underfloor heating or air conditioning. The temperature is either measured by the built-in
sensor or by the optional external remote sensor 9485-F. The room thermostat has a
potential-free relay output. Your underfloor heating can now also be integrated into the
HomePilot® Smart Home with the radio room temperature controller thanks to the integrated
DuoFern radio interface. A stand-alone system can be achieved in combination with the DuoFern
radiator actuator 2. The measured temperature of the room thermostat can optionally be used to
control the radiator actuator (2nd generation). The DuoFern room thermostat can be used and
configured in three different heating modes: room temperature controller room temperature
controller with limiter function and cooling function. The DuoFern room thermostat (2nd
generation) can also be combined with the DuoFern radiator actuator (2nd generation) to control
it. The DuoFern room thermostat can be connected directly to a DuoFern actuator via radio.
Connected to one or more valves this combination therefore enables individual room regulation
without any peripherals. Up to six heating or cooling phases (incl. four target temperatures)
can be configured for each day. The following appliances for example can be connected to the
potential-free relay output: control valves (also extra-low voltage valves) heaters (also
electrical heaters up to max. 2300 W) and air conditioning systems. The remote sensor 9485-F is
optionally available as an external temperature sensor if the internal sensor cannot reliably
record the room temperature. This may be useful if: * The DuoFern room thermostat is installed
in a thermally unfavourable position (e.g. on a cool exterior wall) * Large loads (e.g.
electric heaters) are switched on that significantly heat up the DuoFern room thermostat
(self-heating) The device is manually operated with the plus and minus button. These buttons
can be used to gradually increase or decrease the target temperature by 0.5°C. The DuoFern room
thermostat is designed as a flush-mounted device for indoor rooms. The electrical connection is
carried out by means of the connecting terminals on the rear side of the installation housing.
The DuoFern room thermostat can be integrated into a standard switch range (50 x 50 mm). It may
be necessary to use an intermediate frame measuring 50 x 50 mm (according to DIN 49075)
depending on the switch range used. Overview of functions: * Can be used as a local controller
on site or as a system solution (Homepilot® DuoFern radio system) * Manual operation on site
with the plus and minus buttons * AUTO MANUAL switching * Easy set-up with an installation
wizard * Heating and cooling function depending on the connected device * Configurable for up
to 6 switching times per day and any 4 target temperatures * Optional external temperature
sensor (remote sensor 9485-F) can be used for external temperature measurement or as a
temperature limiter * Control of the valve radiator or air conditioning system in combination
with a DuoFern actuator or also via radio (ideal for retrofitting) * Can be combined with
DuoFern radiator actuators 9433-1 (2nd generation) * Two-step control (on off) with a
configurable hysteresis and adjustable minimum switching time * Manual adjustment of the target
temperature also possible with a manual transmitter (sold separately not included) * Receipt
and display of weather data (temperature brightness wind velocity and rain) in combination
with a DuoFern environmental sensor (sold separately not included) * Three different week
programmes * Automatic button lock * Dimming of the LCD background lighting * Sensor test *
Delete or reset all data The room thermostat is particularly practical as it can also be used
in conservatories: It can provide temperature-dependent sun shading in combination with the
HomePilot®. For instance the preconfigured scene is triggered if a specific temperature is
recorded on the thermostat in summer and sent to the HomePilot: For example the external
Venetian blinds automatically provide sun shading for the conservatory so that the sunlight
does not continue to heat it up.
