Overheating/overcooling switch unit with advanced functions RFSTI-111B
The component measures temperature in the range of 15 to 35 °C with external sensor and on the basis of the set temperature switches air conditioning.
It is particularly suitable for hotel rooms.
With the Window/Door sensor programmed, when the window/door is opened, the device relay contact is automatically disconnected, there by saving unnecessary energy consumed for cooling when the window/door is open.
It enables connection of the switched load up to 12 A (3000 VA).
Up to 4 RFDW-100 detectors can be connected to one RFSTI-111B device.
Range up to 160 m (in open space), if the signal is insufficient between the controller and unit, use the signal repeater RFRP-20 or protocol component RFIO2 that support this feature.
Communication frequency with protocol RFIO2.
The BOX design lets you mount it right in an installation box, a ceiling or controlled appliance cover.
External sensor TC (-20 to +80 °C) or TZ (-40 to +125 °C) for length of 3 m, 6 m, 12 m.
Supply voltage (frequency): AC 230 V (50/60 Hz); AC 120 V (60 Hz)
