2 Safety
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
TopVent® TG, GV and MG units are gas-red warm air heaters with modulating
atmospheric gas burner. All control and safety valves are checked at the factory
and preset according to the specications on the type label. The units are state-of-
the-art design and are safe to operate. 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 dened 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 o󰀨 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.
■Replacement parts must comply with the technical requirements of the system
manufacturer. Hoval recommends the use of original spare parts.
■Unauthorised reconguration or modication of the unit is not permitted.

■Shut down the unit immediately, if any defects are ascertained that limit the
operational safety:
– Close the main shuto󰀨 device in the gas supply line.
– Switch o󰀨 the power supply (main switch in the control panel).
2.3 Decommissioning
■Switch o󰀨 heating operation:
– TopTronic C: Switch the unit to the 'L_OFF' mode.
– TempTronic MTC: Set the room temperature to the lowest setting.
■Close the cut-o󰀨 valve in the gas supply line.
■Let the unit cool o󰀨. The fan continues to run to cool down the heat exchanger.
Attention
Fire hazard due to hot components. Do not switch o󰀨 the power supply
until the fan comes to a complete stop!
■When the fan comes to a stop: switch o󰀨 the plant on the main switch.
2.4 Emergency situations
In emergency situations:
■Disconnect the power supply with the main switch in the control panel. The gas
blower and the fan stop immediately. In this case, the orderly cool down of the
heat exchanger does not happen.
■Close the cut-o󰀨 valve in the gas supply line.
2.5 Regulations
Observe all applicable national regulations and standards as well as generally
accepted engineering practice for the installation and operation of gas-red units.

4 Operating modes
Operating modes with TopTronic®C
The units have the following operating modes:
■Supply air speed 2 (only TopVent® MG)
■Supply air speed 1 (only TopVent® MG)
■Recirculation
■Recirculation speed 1 (only TopVent® TG, MG)
■Standby (Night cooling only TopVent® MG)
The TopTronic® C control system regulates these operating modes automatically
for each control zone in accordance with the specications 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: O󰀨,
Supply air speed 2, Supply air speed 1, Recirculation, Recirculation speed 1.
Code Operating mode Description

Table 1: Operating modes
Operating modes with TempTronic MTC
The TempTronic MTC controls the following operating modes per control zone:
Operating mode Description
Recirculation heating
The unit draws in room air, warms it and blows it back into the room.
3 setpoints can be set for regulation of the room temperature.
The controller operates in one of the following programs, as desired:
■Automatic mode with setpoint changeover according to clock programme
■Continuous operation with the room temperature setpoint day
■Continuous operation with the room temperature setpoint night
■Continuous operation with the room temperature setpoint frost
Fan .................................. modulated 1)
Heating ............................ modulated 1)
1) Depending on heat demand
Destratification
To avoid heat build-up under the ceiling, the fan can be switched on depending on the
temperature stratification. The controller compares the air temperatures in the ceiling area and in
the occupied area, and switches to destratification mode if the difference becomes too great.
Fan .................................. on
Heating ............................ off
Summer ventilation
The fan can be switched manually to 3 speeds.
Fan .................................. speed 1 / 2 / 3
Heating ............................ off
