Description

Description

The model range - 24 kW.

The independent heat exchanger of the hot water supply circuit minimizes the cost of annual maintenance, ensures temperature stability in the hot water circuit and has a longer service life compared to a bitermic heat exchanger.

A high level of unification of components and components for all models of Lemax wall boilers.

Optional connection of remote interior comfort monitoring and control devices (Android and IOS) using the integrated ModBus protocol or relay-type contacts.

The increased volume of the combustion chamber ensures complete combustion of the gas and increases the service life of the heat exchanger.

Double level of protection against excess pressure in the heating circuit, which is provided by a built-in pressure sensor and a relief valve.

Working in systems with high hydraulic resistance makes it possible in most cases to exclude the installation of an additional pump.

Structurally protected sensors and sensors from corrosion and scale.

The extended operating voltage range of the boiler allows for stable operation of the boiler in networks with high and low voltage (185 - 245 v).

The integrated ignition transformer ensures stable spark formation and maximum smoothness of ignition.

The water pressure indicator on the LCD display provides convenient water pressure monitoring.

The ability to connect a room thermostat to adjust the temperature inside the room with high accuracy.

The flow sensor ensures that the hot water supply circuit is turned on at a water flow of 2 l/min and turned off at 1.5 l/min, which allows the use of the hot water supply circuit in rooms with low water pressure.

A bypass is installed in the collector group of the boiler, which protects the boiler elements from overheating when excessive hydraulic resistance appears in the heating system or when the coolant is blocked.

Ease of maintenance of the boiler due to the use of an easily removable top panel.
