Description

LEMAX boilers of the PROPLUS series are made in a stylish modern design.

These are heating element boilers designed as a universal heat source for heating residential and office premises.

The model range is from 4,5 to 24 kW.

99% efficiency ensures high efficiency when using the equipment.

Built-in expansion tank of the Italian brand CIMM.

Structurally built-in sensors: indirect heating tank temperature sensor (indirect heating tank), indoor air temperature sensor.

The possibility of connecting an indirect heating tank (indirect heating tank).

Protection against pump blockage.

Antibacterial protection against legionella formation.

Protection against freezing of the coolant.

Energy-efficient pump with frequency control WILO.

Rotation of heating elements.

Mobile application (Android and iOS).

Instant notification of the owner via the mobile application in case of a boiler malfunction.

The possibility of receiving feedback from the owner about the operation of the boiler.

Built-in Wi-Fi module for remote monitoring and control of boiler and heating system indicators using a mobile application.

Programming the air temperature or the temperature in the heating system for the week ahead.

Possibility to choose the boiler power.

Working in offline mode allows you to set the temperature regime in the room.

Control of all boiler functions on the TOUCH SCREEN panel.

Protection of the user from current leakage: each boiler model is equipped with equipment that turns off the supply of electricity to the boiler when a current leak is detected.

Protection against freezing of the boiler: when reaching 5°C and below, the heating elements are automatically switched on in the boiler and the coolant is heated to a temperature of 30°C.

Protection against overheating of the boiler: the boiler heating elements are automatically switched off when the coolant temperature reaches 110°C.

The easy-to-remove front panel allows maintenance of the boiler without dismantling it from the heating system.

The ability to use the «priority consumer» function.

Two types of temperature control: temperature control can be carried out both by the temperature of the water in the heating system and by the temperature in the room.

The possibility of connecting a room thermostat to adjust the temperature inside the room with high accuracy.

Low-noise power relay: the boiler uses a noise-insulating housing, due to which the sound level is significantly reduced when the heating degree is turned on.

Locking the control panel from children: 20 seconds after the boiler use session, the boiler control panel goes into sleep mode, which makes it impossible to accidentally press the control buttons on the panel.

Saving the set settings in case of an arbitrary power outage: in case of termination and subsequent resumption of power supply, the boiler turns on with the last saved settings.
