Luna3 Comfort HT
Baxi has implemented Luna3 Comfort range with Luna3 Comfort HT new condensing boilers, provided with a remote control panel (wire connection) that, in addition to an easy setting and an immediate diagnostics, enables you to easily interact with the boiler.HT boilers use the new condensing technology recoveringalmost all the heat available through the combustion without wasting energy into the air. The programmablethermoregulation interface, supplied with the boiler,has a modulating regulation that guarantees themaximum effi ciency in the boiler’s operation andconsequently a considerable reduction of consumptions.

Condensing technology is the latest face in boiler innovation.
By employing pre-mixing burner know how, condensing boilers ensure higher performance: almost all the heat
available through combustion is recovered without wasting energy into the air, as happens with traditional boilers.

Environmentally friendlyCondensing pre-mixing boilers are synonymous with
energy savings and reduced emissions. Used in low
temperature systems, condensing boilers tipically
facilitate a cutback of 35% in gas expenditure. Their
ability to signifi cantly reduce noxious gases (up to
80% of NOx and 90% of CO) also makes condensing
boilers environmentally friendly thanks to the use of
pre-mix burners. NOx and CO are pollutants that have
an adverse impact on the environment (e.g. acid rain),
and Baxi is continually researching new environmentally
sustainable solutions.
Comfort right at your fi ngertipsThe remote control panel, supplied with Luna3 Comfort
HT, guarantees a complete comfort managing.
The interaction with the boiler is easier thanks to the
information clearly displayed in the wide LCD and
dedicated push-buttons for the heating and DHW
temperature regulation.
The panel works also as modulating room thermostat
and is provided with a 2 levels weekly timer.

Wide modulation ratioLuna3 Comfort HT is provided with a wide modulation
ratio (1÷6) to cut down the number of repeated boiler’s
switching on/off thanks to reduced minimum output:
besides a better boiler working you will obtain lower
consumptions and lower gas expenditures.
This feature is profi table also in integrated systems
(instantaneous boiler combined with solar system):
regular working of the boiler ensures hot water and
comfort.

Noiseless of HT boilersLuna3 Comfort HT is quietin all operation phases thanks to the soundproofi ng of thecombustion chamber andto the special components.
High energetic effi ciencyLuna3 Comfort HT boilers have obtained 4 stars (★★★★)energetic effi ciency according to European Directive 92/42/CEE.
Low and hightemperature systemsThe electronics of Luna3 Comfort HT enables to manage also low temperature systems. For mixed systems you can use the Baxi Mixed System Kit available as option.
Hydraulic groupIn Luna3 Comfort HT the pre-heating function can be selected: after any hot water demand, the boiler keeps the primary circuit intemperature so that thefollowing hot water demandwill have the desiredtemperature immediately. This function will deactivateautomatically after 60’ of nowater demand to containenergy consumption. Forheating only models, it ispossible to easily connect and control an external cylinder thanks to the built-in 3 way electric valve.
Outdoor sensorLuna3 Comfort HT has a built-in weather compensation function (outdoor sensor available as option) to adjust the heating fl ow temperature according to the external temperature.
Connection to solar systemsCombi models are designed to be easily connected to Baxi integrated solar systems. For the installation, please follow the instruction manual.

Quality and reliability of Baxi boilers range, have
always been guaranteed by a careful choice of each
component. Their positioning has been thought to
make them easily reachable, making the service easier.
Luna3 Comfort HT is provided with all regulation
and control systems to ensure the maximum comfort
and safety:
• Electronic continuous fl ame modulation
• Automatic gradual ignition and control by
fl ame ionization
• Electronic temperatures control by NTC sensors
• Overheat limit thermostat to protect the
primary exchanger
• Hydraulic pressure switch to prevent boiler’s
operating in event of low water
• Post circulation of the pump in central heating
and sanitary modes
• 3 bar pressure relief valve
• On sight manometer to easily check the system
pressure
• Grade of protection: IPX5D

Remote control panel:immediate control and diagnosticsThe new generation of Baxi condensing boilers is supplied with a wide control panel (with a LCD display and wire connection) to guarantee the remote managing of the boiler. The regulations are done directly on the remote control. The advanced electronics enables the installation in low and high temperature systems.
Main functions
• All boiler’s parameters setting and display: room temperature, heating fl ow, climatic curve and DHW temperature setting, heating and DHW set temperature, outdoor temperature display (if the outdoor sensor is connected), level of modulation, hot water fl ow rate.• Self-check and recording of the latest anomalies.• Control of the remote control’s zone valve through the boiler’s electronics.• Built-in weather compensation function. When the external sensor is connected (available as option), the electronics selects automatically the more suitable climatic curve, adapting the heating fl ow temperature according to the external temperature and room temperature.• Central heating mode: 2 levels weekly timer (comfort/economy); the boilers’ functioning settings can be done for single days or for groups of days.• DHW mode: 4 levels daily timer (heating only versions with indirect cylinder connected).• Temporary central heating function selection: possible forcing of the programs for temporary functioning (i.e. holiday, presence setting).• Pre-heating function: after any hot water demand, the boiler keeps the primary circuit in temperature so that the following hot water demands will have the desired temperature immediately. This function will deactivate automatically after 60’ of no water demand to contain energy consumption.
SpecialfunctionDirectly from the control panel the user can activate the SHOWER SETTING, temporarily modifying the domestic hot water temperature, that in a second time will return to the previously set temperature.
