236.4 INSTALLING THE CHROTHERMOSTATON THE WALLFirst step, remove the cover containing the electronicboard by pushing the appropriate button trapezoid, thatsays “PUSH”, located on the lower unit and rotatingthe cover itself up, until it is fully removed, as shown infigure 3.For the fixing on the wall is possible to use many holesprovided on the bottom of the base, in this case, seeFigure 4.Then is possible to wire the circuit board unit using theappropriate terminal, regardless of the polarity (the twoconductors can be exchanged).It is recommended to use a twisted pair cable (exampleH03RR-F o H03VV-F) size between 0,5 mm2 and 2,5mm 2, the length should not exceed 50m. The resistanceof each conductor, in any case, should not exceed 5.In environments with electromagnetic interference it isrecommended to use a shielded twisted pair cable.6.5 DIMENSIONS FIXINGSFig. 5Instructions for unhooking the front panel1) Press PUSH button2) Rotate upwards9,505,009,002,20 5,0010,409,5018,25 17,15ø 3,80Fig. 6Base fixing holes, rear view (dimensions in mm)External dimensions (dimensions in mm)140,090,01,230,8
