Espar has developed a NEW smaller, lighter version of the current ISO adapter. An advanced computerized heater diagnostic that provides detailed information required for troubleshooting your heater. It is similar to the EDiTH basic adapter as it allows easy sharing of the recorded file through email with Espar’s Technical Department, but it does not require the USB to serial adapter. It has three connectors for easy direct connection to most of our available heaters. Additional USB extension is needed for longer reach to the heater to be diagnosed.
