3 Construction and operation
The TopVent® TV is used to heat in recirculation operation; it was developed
specially for use in rooms up to 6 m in height. The unit is installed on the wall or
under the ceiling. It takes in room air, heats it in the heating coil and blows it back
into the room through the air outlet louvre.
There are 3 unit sizes, which are each equipped with an innitely variable fan and
a custom-made heating coil.
3.1 Unit construction
The TopVent® TV consists of the following components:
■ Heat exchanger consisting of copper tubes and aluminium ns
■ Axial fan with energy-saving EC motor and ow-optimised fan blades, innitely
variable, maintenance-free and quiet with a high degree of efciency
■ Compact casing in modern industrial design, consisting of high-quality ABS,
robust and easy to clean
■ Suspension set for installing the unit on the ceiling or the wall
■ Air outlet louvre with vanes for manual adjustment of air distribution

3.2 Operating modes
The TopVent® TV operates in on/off mode. The EasyTronic EC room temperature
controller regulates the operation of the unit.
EasyTronic EC
The EasyTronic EC is a simple room temperature controller without a timer. A
maximum of 10 TopVent® units can be connected to 1 controller.
Functions
■ Recording the room temperature with the integrated temperature sensor
■ Room temperature control in on/off mode: If the room temperature falls below
the setpoint value, the connected TopVent® units switch on. Upon reaching the
setpoint value, the units switch off again.
■ 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).
■ Controlling the fan speed: The required speed can be innitely controlled.
■ Pump or valve control: The EasyTronic EC provides a signal for switching a
pump or a valve (digital output).
