2.2 Operational safety
The unit is built to conform to the state-of-the-art and is operationally safe.
Despite every precaution being taken, potential and not immediately obvious risks
always remain, for example:
■Dangers when working with the electrical system
■Parts (e.g. tools) can fall down below when working on the ventilation unit.
■Malfunctions as a result of defective parts
■Hazards from hot water when working on the hot water supply
Therefore:
■Please read the operating instructions before unpacking, installing, commis-
sioning and before maintaining the equipment.
■Store the operating instructions so that they are easily accessible.
■Observe any attached information and warning signs.
■Immediately replace damaged or removed informational and warning signs.
■Follow the local safety and accident prevention regulations at all times.
■Disconnect the power supply and wait at least 5 minutes before opening the
unit.
■When working in the unit, take precautions against unprotected, sharp metal
edges.
■The unit may only be installed, operated and serviced by authorised, trained
and instructed skilled personnel:
– Specialists as dened by these operating instructions are those persons
who, based on their training, knowledge and experience as well as their

3 Construction and operation
The TopVent®TW serves as an air curtain to protect entrance areas against the
cold. The unit is installed over or next to the door. It takes in room air, heats it by
means of the heating coil and blows it back into the room at a high speed. This
creates a barrier of owing air, which protects the indoor climate from external
inuences.
There are 3 unit sizes, which are each equipped with an innitely variable fan and
a custom-made heating coil.
3.1 Unit construction
The TopVent®TW consists of the following components:
■Heat exchanger consisting of copper tubes and aluminium ns
■Tangential fan with energy-saving EC motor and ow-optimised rotor, innitely
variable, maintenance-free and quiet with a high degree of e󰀩ciency
■Compact casing made of galvanised sheet steel
■Suspension set for vertical or horizontal installation of the unit
■Outlet nozzle

3.2 Operating modes
The TopVent® TW operates in on/o󰀨 mode. The EasyTronic EC room temperature
controller regulates the operation of the unit.
EasyTronic EC
The EasyTronic EC is a room temperature controller with a timer. A maximum of
10 TopVent®units can be connected to 1 controller.
Functions
■Recording the room temperature with the integrated temperature sensor
– Optional: Recording the room temperature with the external temperature
sensor
■Room temperature control in on/o󰀨 mode: If the room temperature falls below
the setpoint value, the connected TopVent®units switch on. Upon reaching the
setpoint value, the units switch o󰀨 again.
■Lowering of the room temperature setpoint value via week programme
■Controlling the TopVent®units using a door contact switch: The connected units
are switched on via door contact if the door is open (digital input).
■Adjusting the fan speed: The required speed can be innitely adjusted.
■Pump or valve control: The EasyTronic EC provides a signal for switching a
pump or a valve (digital output).
