The temperature evaluation+control instrument AT-1 with temperature sensor FT-1 is a universal temperature measuring system to gather and evaluate ambient / outdoor / indoor temperature. Individual and convenient adjustable switching thresholds and delay times are set to control illumination, light, jalousies, marquees, blinds, shutters, air conditioning, heaters, ventilation, flaps, roof hatches and build-ups.
The display at the control instrument shows the individual switching on/off thresholds and corresponding delay times. Furthermore the actual temperature is displayed.
The output relay, with potential-free changeover contact (no/nc), is operated, if adjusted threshold values are reached.
The maintenance-free and weather-proofed (IP67) temperature sensor FT-1 detects and gathers the ambient / outdoor / indoor temperature. The output signal is a square wave signal with proportional frequency to the temperature.
