CONTROLS
Ventus Compact range of oor-mounted units with rotary heat wheel and suspended
with hexagonal recuperator. Equipped with complete, factory mounted controls, pre-congured
in accordance to actual selection and ready to run just after connecting to mains.

Safety
Controls is capable to regulate all user parameters: air temperature, its humidity, maximum permissible CO
2
concentration and the ow rate. Also, controls support preventive and securing functions like protection
of the water heater against freezing or energy recovery system against icing, protection of motors against
overloading, monitoring of air lters actual status of contamination and many other. Applied algorithms can
optimize performance of all air treatment components in order to minimize consumption of all energy media
supplied to the unit. The system includes control and power supply circuits:

PAREMETERS REGULATION FUNCTIONS
Temperature and humidity regulation
» Regulation of supply, return air temperature and humidity in handled spaces.
» Control of water coils valves (heater, cooler) and condensing unit.
» Control of rotary heat wheel revolutions and mixing box (Ventus oor-mounted Compact units), bypass-
damper of hexagonal counterow energy recovery system (suspended VENTUS Compact units).
Airow rate regulation
» Constant Air Volume (CAV) available as standard
» Constant static pressure maintenance in trunk duct (Variable Air Volume – VAV) available as option.
» Getting of constant revolutions for each fan individually – VFD setting for AC motors or constant revolutions
percentage in case of EC motors.
CO
2
regulation
» By means of mixing box – for units with air recirculation.
» By means of airow rate change – for all types of supply and exhaust units
(function can be engages together with mixing box control).
PROTECTION FUNCTION
» Protection against rotary heat wheel icing (VENTUS Compact oor mounted units), by means of wheel
revolutions reduction.
» Protection against hexagonal counterow recuperator icing (VENTUS Compact suspended units)
by means of by-pass damper opening:
optimizing of icing protection function by change of minimum return air temperature threshold downstream
the energy recovery unit vs return air parameters,
minimizing of recovery efciency drop during defrosting.
» Anti-freezing protection of water heater:
antifreeze thermostat installed downstream the heater,
strap-on return water temperature sensor
» Fans overload protection (functions realized by EC motors drives)
» Fire alarm input – AHU immediate disengaging in case of lack of external start permission from overall
re protection system.
TIME SCHEDULE FUNCTIONS
» Weekly schedule operational modes programming.
» Clear visualization of schedule settings by means of web-browser (computers and mobile devices).
HMI Basic
» Engaging and disengaging the AHU,
change of operational modes.
» Change of temperature, airow,
humidity, max CO
2
level settings, etc.
» Errors reporting.
» Time schedule setting.
HMI Advanced
» All users and service functions except
visualization
• AHU engaging and disengaging,
• Change of operational modes.
» Change of temperature, airow,
humidity, max CO
2
level settings, etc.
» Parameters setting and reporting.
» Errors reporting.
» Time schedule setting.
BMS
» User function like in HMI Advanced.
» User’s customized visualization (BMS).
Remote visualization
» All user function like in HMI Advanced:
• VTS visualization.
» Clear interface of schedule
programming, presenting unit’s
operating time individually for each day
of the week.
» Energy consumption analysing module.
» Individual parameters monitoring of
each functional block.
» Filing of all AHU’s parameters recorded
in few minutes intervals.
USER
Change of ductwork resistance
– by adjusting damper
Change of fan revolutions
