VTS HMI BASIC 2 HY VENTUS Compact with Heater User Manual

HMI Basic 2 HY is a basic control panel, designed to operate VTS air handling units equipped with the uPC3 controller.

Panel functions

• AHU starting and stopping
• operating mode selection
• the ability to view and change the parameters of individual operating modes (temperature, humidity, CO2 level, speed of supply and exhaust fans)
• reading of leading, outside and room temperatures (built-in room temperature sensor)
• setting the AHU operation according to the schedule
• alarm handling (viewing, deleting)

Activating the panel in the settings of the AHU controller
The panel is designed for air handling units equipped with the uPC3 controller with software version 1.0.019 or higher. To enable its support, from the level of HMI Advanced (physical, connected to the PLAN port of the controller or virtual, which is part of the visualization application), go to the service menu and change the last digit of the application code on the I01 screen to 7.

After that, on the J03 screen, set the appropriate Modbus address on the HMI Basic line (the default HMI Basic 2 HY address is 16) and activate it by selecting YES.

Display

The visual indication of the fan operation level (point 22 on the display) is based on the current control point of the supply fans and is defined as follows:

If there is no communication with the controller, HMI Basic 2 HY will only display the current room temperature.

Turning the panel on and off
To turn off the panel screen, hold down the button. Switching on is done by briefly pressing the same button. Turning off the HMI panel does not mean turning off the AHU – to turn off the unit, select the Off operating mode.

The display backlight is turned off automatically after a user-defined time. The backlight is activated by pressing any key. After activating the backlight, it is possible to perform further operations with the use of the panel.

Selecting the operating mode
On the main screen, press the button to select the operating mode from among those visible in the upper part of the screen (Off / StandBy / Eco / Opti / Comfort / Auto).

Preview of parameters set for the current operating mode
It is possible to check the chosen values for the selected operating mode:

• set temperature
• humidity
• CO2 level
• supply fan speed (S)
• exhaust fan speed (E)

To do this, press ▲▼ on the main screen.

Changing the parameters of individual operating modes
On the main screen, hold down the button, and then by pressing again, select the mode you are interested in (StandBy / Eco / Opti / Comfort) and confirm your selection with . We now have the option to set the parameters values associated with a given mode:

• set temperature
• humidity
• CO2 level
• supply fan speed (S)
• exhaust fan speed (E)

Access to individual settings depends on the AHU configuration and its actual components.

Changes are done by means of , approval – the button. Exit to the main screen occurs automatically after a moment of inactivity or after pressing .

Change of the temperature displayed on the main screen
HMI Basic 2 HY enables displaying the current value of one of the three temperatures on the main screen: · leading, on the basis of which the AHU operation is carried out (Main)

• external (Ext)
• room (Room)

Switching between them is done by pressing successively on the main screen.

Setting the AHU work schedule
The HMI Basic 2 HY panel is equipped with the possibility of setting and modifying the AHU work schedule. Changes made from the panel level also affect the schedule available in HMI Advanced and the visualization – it does not constitute a separate schedule, but allows full access to the existing one.

On the main screen, hold down the button, and then with successive presses select the Auto submenu and confirm the selection with button.

• Timer – daily schedule that allows you to program up to 4 mode changes each day at a selected time, separately for each day of the week. We select respectively: the day of the week, activation (On / Off) of individual actions, the time at which the action is to be performed and the mode to be set. By confirming the next parameters, we proceed to the parameterization of the next action (digits 1-4 displayed on the right side of the screen determine which of them are currently being set).
•  P – periodic schedule, enabling the selection of up to 3 periods of the year in which the AHU is to operate in the selected mode (this type of schedule has higher priority than the daily schedule). We select respectively: activation (On / Off) of individual periods, date of their end and beginning and the mode to be set. By confirming the next parameters, we proceed to the parameterization of the next period (digits 1-3 displayed on the right side of the screen determine which of them are currently being set).
• S – special schedule that allows to select up to 6 special days a year in which the AHU is to operate in the selected mode (this type of schedule has priority higher than the daily and periodic schedule). We select respectively: activation (On / Off) of a particular special day, its date and mode to be set. By confirming the next parameters, we proceed to the parameterization of the next special day (digits 1-6 displayed on the right side of the screen determine which of them are currently being set).
