During normal work, the temperature controller need not set up all the time at the highest grade, otherwise when electric heater surface operating temperature was close 110 ℃, the difficult action of temperature controller, and long-time high temperature work easily makes inside device burn out ageing or protectiveness suffer destruction. Therefore, the thermostat is set to a proper position when the electric oil heater is used for the first time.
During adjustment, firstly, the temperature controller knob is slightly rotated clockwise to the maximum position, the two-gear power switch is turned on, the whole machine is in the maximum output state, heating is carried out for about 5 minutes, the surface of the upper part of the shell is lightly flapped by the back of a hand, if the sensed temperature is appropriate, the knob is slightly rotated anticlockwise until a crisp contact flicks, meanwhile, a power indicator lamp on the power switch is turned off, and then the knob is slightly rotated clockwise for a small angle so that the contact is not closed. Therefore, the electric heater can provide the satisfied temperature for people after the adjustment is finished. The temperature of the shell surface is about 85 ℃ when slightly scalded. The temperature of the electric heater shell is higher than the set temperature, the temperature controller can automatically cut off the power supply to stop heating, and the heat stored inside continues to be released outwards. When the surface temperature is reduced by 15 ℃, the contact of the temperature controller can be automatically closed, the temperature is raised by electrifying and heating, and when the temperature of the shell is higher than the set temperature, the shell is automatically powered off to stop heating. The process is repeated in this way, and the temperature is kept constant.
