Caution very hot surface.

Caution -portions of this product may become hot and cause burns.Pay particular attention to the presence of

children and vulnerable people.

3. Use of the Xroom unit

1. Unit Designation

- The Xroom is an air-conditioning unit using ventilation technology with recovery of heat (countercurrent

recovery exchanger) and humidity (enthalpy exchanger) with the possibility of independent space heating

at the unit’s installation site (depending on the selected unit type).By default, the unit is equipped with

aCO2air quality sensor (alternatively also with an RH humidity sensor), which allows it to ventilate only

when needed.The user shall set only the unit's output (flow rate, temperature –based on the selected

type) according to the place of use (how many people will be in the room) and the unit will ventilate and

heat as per the actual needs.

-The unit can be used in spaces with the maximum nominal flow requirement:

o100 m3/h – Xroom 100 –regular residential premises, smaller offices, hotel rooms, etc.

o250 m3/h – Xroom 250 –larger office facilities, school classrooms, hospital rooms, etc.

-The unit is designed for horizontal installation on the perimeter wall, which provides simple access to the

outside environment (fresh air).

-You can install the unit in the wall with the minimum thickness of 180 mm.

-The unit is intended for continuous operation with the possibility of using the manual operation mode

(ventilates continuously) or the automatic operation mode (ventilates as needed –required by the air

quality sensors –AQS).

-The unit can be used not only for controlled ventilation, but also for space with heating requirements

(ventilation and heating are independent of each other). In case of type configuration with:

oElectric heating, theunit is equipped with advanced regulation with temperature sensor for the

given area (installation site).Using an integrated temperature sensor, the user can choose the

appropriate temperature degree that meets his requirements,

oWater heating, the unit is equipped with awater exchanger, which is connected to the standard

heating system using an external G 3/4" thread and is controlled using an independent fitting –

thermostatic valve and head (not included in the supply).The unit control is equipped with a

temperature sensor that detects hot water in the exchanger and starts the heating function.The

function of the water heater depends on the function of the boiler –heating system.

-The unit also allows for the antifreeze temperature function (tempering the heated space to prevent

freezing).In the electric version, settings are on the controller, and in the water version, they are on the

thermal head (snowflake symbol).

-The unitis intended for indoor covered and dry areas with aroom temperature of +5 °C to +30 °C and the

maximum relative humidity of 70%, non-condensing.

-The temperature of supplied fresh air from the outside may be between -20 °C and +40 °C (applies to

the version with preheating).If the temperature of the supplied air is lower than -20 °C, the unit may

be switched off automatically in order to protect it from possible damage.

1.3.2. Prohibited environment, use, installation of Xroom:

-Exhausting burning or glowing substances!

-Exhausting readily flammable or explosive gases,

-Exhausting aggressive media,

-Exhausting liquids of any kind,

-In an environment with an increased incidence or risk of explosion, flammable substances, and

increased dust and/or air containing other harmful impurities,

Version 1 – GBR(23/06/2021) D-502-0152

-In an environment with higher condensation humidity, such as: bathrooms, swimming pools, saunas,

etc.,

-The unit must not be installed just below the electrical socket or wiring box,

-The unit must not be installed in aposition that could affect its proper functioning, or near the curtains

or other flammable materials.

-Neither the manufacturer nor the supplier is liable for damage caused by improper use of the units. The

user bears the risk.

4. Transport, Delivery Control, and Storage

1. Transport
