All functions indicated in this section are installed in the software of the control board. However, operation and control of the device depends on the
following:
1. Selected control panel. Full functionality and conguration possibility can be assured only by MB-Gateway web interface or Ptouch control
panel.
2. Connected external devices: external heaters, dampers, sensors and etc. (see the description of the acquired air handling system).
3. Internal components of the device: type of heat exchanger (plate or rotor), integrated dampers, sensors and etc. (see components of the chosen
device).
4. Control board type. Di󰀨erent boards provide an opportunity to connect di󰀨erent components. (See scheme of the device board).
Air Handling Unit uses MCB board.
The unit can be congured only with Ptouch remote control
panel or MB-Gateway web application.
The following control board functions can be fully controlled
only with Ptouch remote control panel or MB-Gateway web
application. In case of Stouch remote control panel use the
description of remote control panel functions for MCB control
board.
System modes:
• Stand-by
• Building protection
• Economy
• Comfort
In stand-by mode the system is shut down for a permissible shutdown period (based on the stand-by mode blocking function settings).
The building protection mode is designed to protect a building against moisture accumulation. In this mode the system operates at speed 1. By default,
in this mode temperature maintenance is controlled (preferred temperature is indicated). However, if necessary, temperature maintenance can be
switched o󰀨.
Economy mode is designed to save energy when people are not in the room. In this mode the system operates at speed 2. By default, in this mode
temperature maintenance is controlled (preferred temperature is indicated). However, if necessary, temperature maintenance can be switched o󰀨.
Comfort mode is used when people are present in the room. In this mode the system operates at speed 3. In this mode the temperature is always
maintained.
System mode can be changed automatically by the functions (in a sequential order as indicated):
1 - Weekly Schedule
2 - Mode is activated from an external contactor
3 - User’s manual mode selection
4 - Holiday Schedule
5 - Stand-by mode blocking

Based on the weekly schedule the system decides which mode it will be operating in; however, the user may change the existing mode manually. The
system will inform when the next mode change is scheduled. After power loss the mode is selected based on the weekly schedule; however, if the
schedule is not set, the mode used before the power loss will be activated.
The user may change modes only when the mode is activated from an external contactor. The only case when the user cannot change the mode is
when the period of a holiday schedule is active. The system informs that the holiday schedule mode is active. To prevent blocking, the period of the
holiday schedule must be changed.
Stand-by mode can be blocked based on selected parameters. If at least one of the above functions changes its mode into stand-by mode, it must be
checked whether this mode is not currently blocked. If it is blocked, the previous selected mode is on.
The function order is provided below.
Proper date and time must be set to have proper functioning of schedules, event log and winter/summer function. Fast synchronization with the com-
puter time is possible in user and adjuster environments.
