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 innitely 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, innitely
variable, maintenance-free and quiet with a high degree of e󰀩ciency
■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
A room temperature controller with or without a timer 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.
Function
■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).
