Switch unit with a temperature sensor – RFSTI-11G

• The thermo-regulation drive measures the (internal / external) temperature by external sensor, and controls the heating circuit (electric
underfl oor heating, air conditioning, boiler, etc.).
• Function:
– Internal – measures temperature by internal sensor and sends it to
the system unit.
– External – measures temperature by external sensor and sends it to
the system unit.
– Combo – measure room temperature by internal sensor and monitors critical fl oor temperature by external sensor.
• These can be combined with system units: smart RF box eLAN-RF or
touch unit RF Touch.
• Manual control of temperature directly using buttons on the unit,
where by pressing the upper button, a command is sent for automatic
switching to the mode Party (preset temperature), and a press of the
lower button sends a signal for switching to energy-saving mode (the
change in temperature applies until the next set change of the heating program).
• Indication of status switched ON/OFF is provided by (red/blue) LED,
which is found under the transparent cover of the temperature unit.
• It measures temperature in a range of -20-50 °C and sends it to the
system unit in regular 5-min. intervals. It sends a signal upon sudden
temperature change within 1 min.
• Setting the heat/cool function, hysteresis and off set is performed in
the system unit or application.
• Switch design (design LOGUS90) off ers mounting in an installation box.
• It enables connection of the switched load up to 8 A (2 000 W).
• The unit power supply is 110-230 V AC.
• For components it is possible to set the repeater function via the RFAF
/ USB service device.
• Range up to 160 m (in open space), if the signal is insuffi cient between
the controller and unit, use the signal repeater RFRP-20 or protocol
component RFIO2
that support this feature.
• Communication frequency with bidirectional protocol iNELS RF Control2
(RFIO2
).
• Color combination of heating unit in design of frames LOGUS90 (plastic, glass, wood, metal, stone).
• External sensor TC (0 ..+70 °C) or TZ (-40 ..+125 °C) for length of 0.11 m,
3 m, 6 m, 12 m.
