0. FOREWORD

READ THESE INSTRUCTIONS CAREFULLY BEFORE STARTING TO USE THE EQUIPMENT.

The present instructions contain the information necessary for operating an installation and the mechanical
ventilation heat recovery (MVHR) unit of the type thermos 200 / 300 DC. They also include maintenance
and service instructions.
This document is intended to teach you in a simple way how to use your heat recovery unit in the best way.
If any interventions into the MVHR unit are necessary, you are recommended to call in your installer.

The MVHR unit is subject to permanent improvement and development. So your equipment may differ in
minor details from this description.

We wish you much pleasure with your MVHR thermos 200 / 300 DC.

prior notice.

1. Brief description

1.1 Construction

The compact mechanical ventilation heat recovery (MVHR) unit is delivered ready for connection. It
comprises the heat recovery unit, the control system and the associated programmer. A 3-metre long cable
is used to connect the MVHR unit with the control system. The link cable between the programmer and the
control unit may have a maximum length of 15 m and shall be provided by the customer who shall also
provide the control unit’s connection with the power supply.

1.2

Housing, heat and sound insulation

The fan and heat exchanger box subassemblies are releasably connected by means of assembly clips.
The entire housing consists of polypropylene (PP) foam and has no metal parts (full heat protection); the
components and subassemblies are embedded in the heat insulating foam material. The foam is also used
as sound absorbent material. It is recommended to connect a silencer (or 1...2 m long soundproofed flex
hose

∅

250 mm) to each of the 4 air outlets of the unit (especially to those communicating with the rooms:

supply air and extract air). The air duct connections with the equipment must be flexible.

1.3 Heat

exchanger

The specific design of the high-efficiency counter-flow channel-type heat exchanger, which is disclosed in
German and European patents, is such that the plastic ducts for the extract and supply air are arranged in
a checker board pattern, which provides a surface area twice the thermal efficiency of plate heat
exchangers; the two fluids (supply air and extract air) are hermetically separated from one another.

1.4 Summer

bypass

The thermos 200/300 DC MVHR unit is equipped with a motorised bypass valve and a bypass shut-off
with safety functions for winter operation.

1.5 Ventilation

fans

The unit comprises two electronically commutated maintenance-free 230 VAC radial fans with integrated
power pack. The specific power consumption thus achieved is as low as 0.36 Wh/m³ (Passiv Haus
certificate).
The air flow rates can be varied by the user. Please note that the short presence of just a few number of
people means low emission of CO

, humidity and smells into the room air and so it is possible to largely

reduce the air flow. A second beneficial aspect is that this avoids an excessively dry room climate when
outdoor temperatures are low (dry intake air).
