Lessar Air Conditioner Error Codes

Lessar air-conditioners have proven to be highly reliable and economical systems. Over the design of air conditioners are well-known

Designers, so all models are distinguished by a special style and modernity.

Air conditioners are made on the basis of materials that reduce

Energy costs and increase the service life of equipment. Conditioners Lessar have a high level of reliability.

E0 - error occurred in the flow sensor;

E1 - wrong phase rotation is performed;

E2 - a communication error has occurred;

E3 - there was an error in the temperature sensor of direct water;
