• Turn OFF the power supply when replacing a cartridge.
• Damaged cartridges can be replaced without disconnecting the wires.
• If the temperature indicator changes from pink to red triac circuits may be malfunctioning, replace.
• Improve heat radiation efficiency before cartridge replacement.

Zero cross function will allow the relay to turn ON when the AC load power supply approaches 0 V suppressing any noise generated with a sudden load current increase. Zero cross function is effective across 2 types of noise, noise on power lines and noise emitted into open space.
