If the bypass damper opens only a few percent, noise can occur, thus minimum opening is limited, which also applies when coming to the full

opening. If the plate heat exchanger with a 3-way bypass damper is used, the opening time of the bypass damper is indicated in the window SERVICE

› HEAT EXCHANGER.

If a plate heat exchanger with segment valves is controlled by an external controller is used, then the type of the bypass damper "REMOTE CONTROLLER"

is shown in the window "SERVICE › HEAT EXCHANGER".

If a plate heat exchanger with segment valves connected to a controller is used, then the type of the bypass damper is shown in the window "SERVICE

› HEAT EXCHANGER" as either "2 SEGMENTS" or "3 SEGMENTS". In the case of heat recovery control, segments are closed in sequence, i.e. if heat recovery is

not required, then all the segments are closed and the bypass damper is opened.

When the fans are switched on during the heating season, the heat exchanger runs for 10 minutes at full power, until the system stabilizes.

19.18. SYSTEM MONITORING

The service and adjuster environment have the window MONITORING where you can monitor operation of the entire system, i.e. see controller

input and output, CO

values, versions of connected modules, date and time, speed of fans, temperatures, pressure, etc. The amount of informa-

tion depends on the system configuration. This tool is designed for preventive maintenance of the system.

19.19. STAND-BY MODE BLOCKING

This function is designed to protect the system against the impermissible unit shutdown and it is recommended to limit the unit shutdown up to 1

hour within 12 hours during the winter season. Possible function modes:

Always allow shutdown;

Block shutdown;

Block shutdown in winter;

Block shutdown in summer.

It must be indicated for how long the shutdown is permissible within 12 hours. If it is blocked and the system is shut down, the system counts and

informs the user on the remaining time. This function is configured in the service environment (SERVICE › MAIN › SYSTEM BLOCKING).

If the time has expired and Stand-by mode is blocked, the user is informed by the function indication.

19.20. AIR FLOW ADJUSTMENT

Air-flows are adjusted in the adjuster environment window ADJUSTER › AIR FLOWS ADJUSTING. There are 4 of them in the system and they are dedicated to

specific modes:

Building protection;

Economy;

Comfort;

Maximum power (BOOST function).

Air-flows are arranged in an ascending order, i.e. upon setting lower air-flow in COMFORT mode then in ECONOMY mode, the air-flow of the latter is re-

duced automatically. With respect to the system configuration, air-flows are indicated in percentage, pressure or amounts of air. 100 % value of

air-flow is indicated in service environment window SERVICE › FANS › FAN SPEED CONTROL.

19.21. MANUAL CONTROL OF COMPONENTS

This function manually activates/deactivates the components controlled by digital and analogue outputs. The latter ones are controlled in percent-

age, and digital ones – by ON/OFF. Based on manufacturer's parameters (by default) the status of all components is AUTO, which means that control

is based on air handling unit operating algorithm. Components are displayed by the system configuration. Settings must be saved so they remain

active after power loss.

The lowest power consumption is when the Stand-by mode is on, and position of components – AUTO.

Prior to using the manual control function, it is recommended to activate the force shutdown function, which blocks the air handling unit operating

algorithm.

This can be useful, if you need to check if everything is properly connected. Moreover, in the event of failure, certain components can be activated

so that the unit operates irrespective of sensors and protections. Of course, this method should be applied in exceptional cases until the failure

is rectified.

If the service environment window SERVICE › SENSORS displays an external (REMOTE) type of a temperature sensor, its temperature may be indicated man-

ually. The values may be indicated via the Modbus interface.

19.22. CHANGING PASSWORDS

In the service environment section SERVICE › MAIN › PASSWORD › PASSWORD CHANGING MODE › ON you can change login passwords. For this it is necessary to acti-

vate the change and after entering a preferred password (4 digits), click a button SET. To review and change the parameters without a password,

just set 0.
