7. ts Switching On and Off The temperature switch is switched on when the supply voltage is applied There is no on off switch A brief initialization phase occurs when the supply voltage is applied to the switch The display and the set point LED illuminate The measuring range min and max temperature and the unit are indicated briefly The outputs are inactive during this time After initialization the switch is in normal operating mode The temperature appears on the display the switching outputs are active and the LED s indicate the status of the switching outputs Programming Briefly pressing button 51 52 causes the relevant set point to be displayed The status LED s flash for as long as the set points are being displayed Pressing the buttons for longer press and hold down button until display flashes causes the current temperature to be taken over as the set point The hysteresis remains unchanged The switching output s can be programmed using the control buttons independently from the present temperature per the programming sequence on page 6 The programming sequence must run without interruptions If delays of about 20 seconds or more occur the switch automatically exits programming mode and switches to normal mode All previous changes are lost Status LED Switching Output Parameter description programming With two switching outputs Temperature units Select set point for first switch
