1) For RTD input, 3 wires with low resistance and no difference should be used.
2) The input signal line should be far away from the power line of the instrument, the power supply line and the load line to avoid noise and annoyance.
3) The power cord of the instrument is generally annoyed by the power supply.
4) When the instrument makes up for the external noise annoyance, it is necessary to use a clutter filter.
5) Equip the noise filter on the surface board and connect it to the ground, and reduce the wiring distance between the noise filter output and the power terminal of the instrument.
6) Do not use the fuse and switch at the output of the filter to reduce the effect of the filter.
7) After the power is turned on, it takes 5-6 seconds to prepare the surface output by the relay, such as when it is used for external connection loops and other signals, please use the delay relay at the same time.
8) This instrument has no power switch and fuse, assuming that the demand can be installed Recommended fuse specification: rated voltage 250V rated current 1A Fuse type: delay fuse.
9) Do not overtighten the terminal screws. In addition, suitable terminal screw lugs are used.

Common faults and analysis of thermostats
Common faults of thermostats
1. There is no display when the power is on. This type of problem first determines whether the power supply is available and whether the power supply matches the power supply required by the thermostat, and then checks whether the wiring is secure. The problem is still there, then it is the problem of the thermostat itself.
2. There is a display, and the control is wrong. This...

RKC Thermostat Common faults of thermostats
The power indicator is normal, but the temperature control meter has no on-screen display. This kind of fault is mostly caused by the heating of the voltage regulator element (7805 or 7812) of the temperature controller during long-term use, resulting in a break point in the solder joint, and sometimes a virtual soldering occurs at the factory, resulting in re-soldering.
