• 1. Do not damage the insulation layer on the surface of hot wire. When laying hot wire, you can fix it with plastic rope. If watering, add the hot line to spray water on top of the problem.

• 2. The temperature difference set by the thermostat must be above 5 temperature values, such as 10-15, 13-18, 24-29, etc. General heating equipment will make a room temperature, temperature changes will not be too large.

• 3. Temperature controller is an electronic device, so it should not be placed in the environment with high humidity and should not be exposed to the sun. It can be placed outside of a small conservatory.

• 4. The temperature controller is based on the temperature probe (as shown in the picture) to measure the temperature in the room. Therefore, the temperature probe should be placed in the central part of the room, not close to the heating line. The temperature probe is not waterproof and cannot be placed in water. Special waterproof probe if necessary.

This batch of thermostats is an upgraded version with the following functions added:

• 1. Temperature calibration function. If the temperature is not correct, the user can adjust it by himself.
• 2. High temperature alarm function. When the temperature continues to rise 7 degrees after the output is off, the buzzer will alarm.
• 3. Temperature control error.
• 4.Permanent memory. After the power outage, the parameters set will be remembered forever.
