Wall-hung for outdoor installation 

EOLO Extra 32 kW X is the wall-hung room sealed fan assisted 

boiler for central heating only, type approved for working 

outdoors also in the open using a special top covering kit 

(optional). 

All boilers are equipped with an antifreeze system as a standard 

feature, protecting them from temperatures down to -15°C. 

Thanks to an optional kit, the boiler can be connected to a 

separate Immergas Storage Tank, with capacities of 80, 105, 

120 and 200 litres, guaranteeing an abundant production of 

hot water, ideal above all for homes where there is more than 

one bathroom or wherever a lot of hot water is needed quickly. 

The boiler can be connected to a water type air heater (Fan 

Heating Unit) for heating places such as garages, car body 

shops, public entertainment premises, gyms, etc. The Remote 

Control, a standard feature with the boiler, is used to control 

the boiler from inside the house easily and immediately. A wide 

range of couple-on extraction and exhaust kits is available to 

complete installation, all with a couple-on fixing system and 

silicone seals.

vessel, with preload at 1.0 bar, 3 bar system safety valve, 

thermometer and manometer; 

• overtemperature safety thermostat; 

• remote control featuring a selector for setting the central heating 

system temperature, a selector for setting the domestic 

hot water temperature, function selector switch (off, summer, 

winter), climatic thermoregulating system, self-diagnostics 

system, weekly timer/room thermostat, digital display; 

• control panel featuring a main selector switch with the 

function of: Stand-by, On, Programming, Reset; the boiler 

is equipped with a microprocessor controlled p.c.b. with continuous 

flame modulation where the modulation field goes 

from 32.0 to 10.5 kW (from 27,520 to 9,030 kcal/h); 

• self-diagnostics system, displaying operating status and 

malfunctions with LEDs; 

• setting the boiler operating parameters by means of the knobs, 

displaying status and functioning mode with LEDs; 

• ignition delay device in the central heating phase, antifreeze 

protection system (up to -15°C), circulator antiblock function, 

post-ventilation function, chimneysweep function, 

pump functioning mode selection, designed for connecting 

the external probe and control unit for zone systems; 

• electronic ignition with ionisation control; 

• IPX5D electrical insulation level; 

Supplied complete with combustion analysis holes, bottom 

protection grille, coupling unit with depth adjustable fittings, 

gas cutoff cock and filling valve. 

Appliance category II 2H3+ works with Natural Gas, LPG and air 

mixed with propane (50% air - 50% propane) only by using 

the conversion kit (optional) with the CE mark.

4 REMOTE CONTROL 

4.1 FEATURES 

Two wires (with a minimum cross section of 0.50 mm 2 and 

max. 2.5 mm 2 ) are used for connecting to the boiler, maximum 

50 metres in length. 

The Remote Control is divided into two completely separate 

sectors: 

• SECTOR FOR SETTING THE TEMPEATURES AND 

BOILER FUNCTIONING MODES. 

Possibility of working in the antifreeze position: with the 

knob on 0 the remote control enables boiler ignition only 

when room temperature drops below +5°C (OFF appears 

on the display if the room probe is not disabled). 

Summer position: the regulator enables the d.h.w. function. 

The temperature is set with the knob and shown on 

the display while it is being set. 

Winter position: the regulator enables operation in both the 

d.h.w. and central heating circuits. The temperatures wanted 

can be set with the knobs and are shown on the display while 

they are being set. 

• SECTOR FOR PROGRAMMING THE TIMES AND 

ROOM TEMPERATURE. 

Manual operation: it works in a range between 5°C and 

30°C. 

Automatic operation: 2 different control levels (comfort 

and reduced) can be set in the day and in the week. 

4 



The Remote Control is used to remotely control and programme 

boiler operation. 

It has been designed to guarantee ideal temperature conditions 

all night and day each day of the week. The main features that 

distinguish the Immergas Remote Control are the simplicity 

and clarity of the controls and how easy it is to connect it to the 

boiler’s electrical control panel. With just two wires, it receives 

electricity and sends control and adjustment commands. 

Automatic operation with a set programme: the Remote 

Control has a “standard” weekly programmed already 

stored. 

Diagnostics: the Remote Control controls boiler status 

continuously and signals any malfunctions giving the corresponding 

error code on the display. 

The delivery temperature, set room temperature and outdoor 

temperature can be seen on the display if the external probe 

is connected. 

Additional functions: the Remote Control is set so the 

indoor room temperature probe can be excluded. 

The remote control can work with ON-OFF or Modulating 

adjustment. The appliance is supplied set for modulating 

operation which can be excluded by changing over to the 

ON-OFF mode. 

Boiler with external probe: the boiler’s electronic card is set 

for using the external probe. 

By turning the heating adjustment selector you can set the 

ratio between the outdoor temperature and the heating water 

temperature according to nine set curves. 

A number between 0 and 9 appears on the display which 

indicates the curve selected.

TV 32 KW FAN HEATING UNIT 

12 TV 32 KW MAIN FEATURES 

The TV 32 kW fan heating unit consists of: 

• a prevarnished steel sheet casing with ABS corners, internally 

insulated to prevent the formation of condensation on the 

unit when working with chilled water; 

• adjustable aluminium deflector fins (spring operated) on the 

air delivery for optimum distribution of the air inside the air 

conditioned room; 

• brackets for fixing the supporting templates (available as an 

optional); 

• heat exchange battery consisting of copper pipes and aluminium 

fins with high thermal conductivity; 

• galvanised steel sheet condensation collection tank, insulated 

with closed cell polyurethane, connected to an auxiliary 

tank; 

• single-phase 230 V 3-speed electric motors (1400, 900 and 

700 rpm) with internal heat protection (clicson), class F 

winding, with IP 55 protection level; 

In its range of products Immergas proposes a water type air 

heater to use with the EOLO Extra 32 kW boiler thanks to 

which garages, car body shops, painting shops, carpenters, 

public entertainment premises, gyms, etc., can be heated. 

The boiler, placed outdoors for example, heats the convector 

fluid which, by way of the boiler circulator and connecting 

pipes, is sent to the air heater, equipped with a heat exchanger 

and high air flow rate fans that heat the rooms quickly. 

The TV 32 kW fan heating unit is distinguished by its rounded 

design, its technical features (3-speed standard motor, set for 

working with chilled water) and low noise operation. 

One of the TV 32 kW fan heating unit’s standard features is 

its microprocessor control panel (MICROPRO D) used to 

control the unit automatically, set and vary fan speed (manual 

or automatic), set room temperature and switch from the heating 

to the cooling mode. 

• axial fan with crescent-shaped blades, statically balanced to 

minimise noise; 

• accident prevention grille in electrogalvanised steel wire 

that supports the motor and is fixed to the unit by means of 

vibration proof supports; 

• microprocessor control panel (MICROPRO D), featuring 

a speed selector switch, electronic thermostat and seasonal 

selector switch; with this panel you can set and alter fan speed 

(manual or automatic), set room temperature and switch 

from the heating to cooling mode; 

• power board for connection of the MICROPRO D control 

panel; 

• electronic water temperature measuring probe for the MI- 

CROPRO D control panel.
