■Supplementary heating with electric heating coil (option)
■Supplementary heating with hot water
(with connection to a hot water supply, option)
■Recirculation operation
■Air distribution and destratification with adjustable Air-Injector
■Air filtration (option)
TopVent®TP units comply with all the requirements of the Ecodesign Directive
2009/125/EC relating to environmentally friendly design of ventilation systems.
They are systems of the 'fan coil unit' type.
Intended use also includes compliance with the operating instructions. Any usage
over and above this use is considered to be not as intended. The manufacturer
can accept no liability for damage resulting from improper use.
1.2 User group
The units are only allowed to be installed, operated and maintained by authorised
and instructed personnel who are well acquainted with the units and are informed
about possible dangers.

■Parts (e.g. tools) can fall down below when working on the ventilation unit.
■Dangers from working on the roof
■Damage to devices or components due to lightning
■Malfunctions as a result of defective parts
■Hazards from hot components when working on the electric heating coil
■Hazards from hot water when working on the hot water supply
Therefore:
■Please read the operating instructions before unpacking, installing,
commissioning 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.
■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 defined by these operating instructions are those persons
who, based on their training, knowledge and experience as well as their
knowledge of the relevant regulations and guidelines, can carry out the work
assigned to them and recognise potential hazards.
■Unauthorised reconfiguration or modification of the unit is not permitted.

3.4 Operating modes
The TopVent®TP has the following operating modes:
■Recirculation
■Recirculation speed 1
■Standby
The TopTronic®C control system regulates these operating modes automatically
for each control zone in accordance with the specifications in the calendar. The
following points also apply:
■The operating mode of a control zone can be switched over manually.
■Each TopVent®unit can operate individually in a local operating mode:
Off, Recirculation, Recirculation speed 1, Forced heating.
Code Operating mode Description
REC Recirculation
On/Off operation: during heat or cool demand, the unit draws in
room air, heats or cools it and blows it back into the room. The room
temperature set value day is active.
Fan .................................. speed 1 / 2 1)
Heating/cooling ................ on 1)
1) Depending on heat or cool demand
DES ■Destratification:
To avoid heat build-up under the ceiling, it may be appropriate
to switch on the fan when there is no heat or cool demand
(either in permanent operation or in on/off operation depending
on the temperature stratification, as desired).
Fan .................................. speed 2
Heating/cooling ................ off
REC1 Recirculation speed 1
The same as REC, but the unit operates only at speed 1
(low air flow rate)
Fan .................................. speed 1
Heating/cooling ................ on 1)
1) Depending on heat or cool demand
DES ■Destratification:
The same as for REC, but the unit operates only at speed 1
Fan .................................. speed 1
Heating/cooling ................ off
ST Standby
The unit is ready for operation. The following operating modes are
activated if required:
CPR ■Cooling protection:
If the room temperature drops below the set value for cooling
protection, the unit heats up the room in recirculation operation.
Fan .................................. speed 2
Heating ............................ on
OPR ■Overheating protection:
If the room temperature rises above the set value for over-
heating protection, the unit cools down the room in recirculation
operation.
Fan .................................. speed 2
Cooling............................. on
L_OFF Off (local operating mode)
The unit is switched off.
Fan .................................. off
Heating/cooling ................ off
–Forced heating (only for units with supplementary heater)
The unit draws in room air, warms it and blows it back into the room.
Forced heating is activated by connecting the unit to a power supply
(only if there is no bus connection to the zone controller). For
example, it is suitable for heating the hall before taking the control
system into operation or if the controller fails during the heating
period.
Fan .................................. speed 2
Heating ............................ on
