Digital input operating mode: configure the digital input function: c-H = to invert the kind of action: direct - reverse;... - Page 16 To obtain an IP65 protection grade use the front panel rubber gasket (mod. RG-C) as shown in figure. The temperature range allowed for correct operation is 0÷60 °C. Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. Let air circulate by the cooling holes.

Digital input XT110C and XT111C have 1 free contact digital input. It is programmable in 5 different configurations by the “i1F” parameter. invert the kind of action: heatingcooling (I1F = C-H) This function allows to invert the regulation of the controller: from direct to inverse and viceversa. REMOTE ON/OFF (I1F = OFF) This function allows to switch ON and OFF the instrument. -
