1 Use
1.1 Intended use
RoofVent®RP units are supply and extract air handling units for heating and
cooling spaces up to 25 m in height with decentralised heat pump. They have the
following functions:
■Fresh air supply
■Extract air removal
■Heating and cooling with heat pump
■Energy recovery with highly efficient plate heat exchanger
■Filtering of the fresh air and the extract air
■Air distribution and destratification with adjustable Air-Injector
The RoofVent®RP unit complies with all the requirements of the Ecodesign
Directive 2009/125/EC relating to environmentally friendly design of ventilation
systems. It is a system of the 'non-residential ventilation unit' (NRVU) and 'bidi-
rectional ventilation unit' (BVU) type, provided for in Commission Regulation (EU)
1253/2014.
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.
The operating instructions are for operating engineers as well as specialists in
building, heating and ventilation technology.

2.1 Symbols
Caution
This symbol warns against risk of injury. Please heed all instructions
designated by this symbol to prevent injuries and/or death.
Attention
This symbol warns against property damage. Please heed the respective
instructions to prevent risk of damage to the unit and its functions.
Notice
This symbol denotes information about the economic use of the equipment
or special tips.
2.2 Operational safety
RoofVent®units are state-of-the-art design and are safe to operate. All control
and safety valves are checked at the factory. Nevertheless, hazards may emanate
from the units if they are used incorrectly or not used as intended. Therefore:
■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.
■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.
■Observe the particular dangers involved in working on the roof and on electrical
systems.
■When working on the unit, objects (e.g. tools) could be dropped. Block off the
area underneath the unit.
■Do not attach additional loads to the unit.
■When working in the unit, take precautions against unprotected, sharp metal
edges.
■Wear suitable protective equipment (helmet, gloves, mouth protection,
goggles).
■Following maintenance work, professionally reassemble all dismantled
protective devices.
■Ensure that all access doors are properly closed to prevent water entry through
the roof unit.
■Replacement parts must comply with the technical requirements of the system
manufacturer. Hoval recommends the use of original spare parts.
■Unauthorised reconfiguration or modification of the unit is not permitted.
■Shut down the unit immediately, if any defects are ascertained that limit the
operational safety.

2.3 Decommissioning
Disconnect the power supply with the main switch in the control panel.
Caution
The use of condensers can pose a danger of fatal injury from directly
touching live parts even after the unit is switched off. Only open the access
doors after waiting 3 minutes.

3.3 Operating modes
The RoofVent®RP has the following operating modes:
■Ventilation
■Ventilation (reduced)
■Air quality
■Recirculation
■Exhaust air
■Supply air
■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 RoofVent®unit can operate individually in a local
operating mode: Off, Recirculation, Supply air, Exhaust
air, Ventilation.
Code Operating mode Description
VE Ventilation
The unit blows fresh air into the room and exhausts polluted room
air. The room temperature set value day is active. Depending on the
temperature conditions, the system continuously controls:
■the energy recovery
■the heating/cooling
Supply air fan................... on 1)
Exhaust air fan................. on 1)
Energy recovery............... 0-100 %
Extract air damper............ open
Recirculation damper ....... closed
Heating/cooling ................ 0-100 %
1) Adjustable flow rate
VEL Ventilation (reduced)
As VE, but the unit only operates with the set minimum values for
the supply and exhaust air volumes
Supply air fan................... MIN
Exhaust air fan................. MIN
Energy recovery............... 0-100 %
Extract air damper............ open
Recirculation damper ....... closed
Heating/cooling ................ 0-100 %
AQ Air quality
This is the operating mode for demand-controlled ventilation of the
room. The room temperature set value day is active. Depending on
the temperature conditions, the system continuously controls:
■the energy recovery
■the heating/cooling
Depending on the room air quality or room air humidity, the system
operates in one of the following operating states:
AQ_REC ■Air quality Recirculation:
When air quality is good and air humidity appropriate, the unit
heats or cools in recirculation operation.
Like REC
AQ_ECO ■Air quality Mixed air:
When ventilation requirements are medium, the unit heats or
cools in mixed air operation. The supply and exhaust air volume
is based on the air quality.
Supply air fan................... MIN-MAX
Exhaust air fan................. MIN-MAX
Energy recovery............... 0-100 %
Extract air damper............ 50 %
Recirculation damper ....... 50 %
Heating/cooling ................ 0-100 %
AQ_VE ■Air quality Ventilation:
When ventilation requirements are high or the room air humidity
is too high, the unit heats or cools in pure ventilation operation.
The supply and exhaust air volume is based on the air quality.
Supply air fan................... MIN-MAX
Exhaust air fan................. MIN-MAX
Energy recovery............... 0-100 %
Extract air damper............ open
Recirculation damper ....... closed
Heating/cooling ................ 0-100 %
