2. Green – COMM – to indicate the state of Modbus Master communication line
a. Off – no communication, HMI OPTIMA not connected
b. Blinking – in case of stable communication
!
1. All control boxes of the VS…CG OPTIMA… typeline need to be powered from the main
switchgear equipped with appropriate protection of wires powering the control box.
2. Assembly, wiring and start-up of the control gear should by done by qualified staff only.
3. Control boxes VS…CG OPTIMA… are intended only for indoor operation.

▪Off – no power supply, lost communication with the controller,
HMI malfunction possible
▪Blinking green – correct and stable communication with the
controller
▪Flashing red – new alarm needs to be acknowledged
▪Permanent red – acknowledged alarm requires further actions
to remove the cause of the problem
Functions:

!
Parameters available in the LCD window depends on a AHU type and the control
application. Hence in AHUs not equipped with heater, options related to the heating
module will not be visible.
SYSTEM START-UP
!
Operation of the AHU is strictly arrested by the fire-protection alarm, activation of the
thermal protection of fans' motors, threefold activation of the protection of electric heater
and threefold activation of the anti-frost thermostat. Each of these events requires
removing the cause of the alarm and then canceling it (see more details in Advanced
Manual).
SWITCHING ON POWER SUPPLY
Switching on power supply of the control gear with the mains switch (Q1M). Correct controller operation is
indicated by green LED “COMM” blinking on the PCB inside the control box and on the HMI OPTIMA device.
The system is ready for operation immediately after switching on.
QUICK START
For quick access there are four screens with the most
basic information and settings. These are sufficient for daily
operation. To run the unit quickly just do:
▪Check the Unit state screen
Stop means, the unit is already configured, is free of
alarms and other malfunctions and is ready to run
▪Check the Temp. setting and put the correct value if
necessary
▪Check the Temp.readout
▪Select the Operation mode according to current
expectations
1. Stop – unit remains stopped
2. Stage I – unit run, fans set to 1st speed (low capacity)
3. Stage II – unit run, fans set to 2nd speed (high capac.)
4. Standby – unit stopped to save energy, but ready for
automatic start up, to keep the temperature within
specified safe range
5. Calendar – unit working automatically, according to the
real time clock settings

2. APPLICATION BASICS
MAIN MENU STRUCTURE
Unit state – indicates the current state of the air handling unit
and the control system
▪Stop – normal stop of the unit
▪Running – normal operation of the unit with ventilation and
heating / cooling / recovery enabled according to current
unit state and demand
▪Alarm state – unit in alarm state
▪Fault stop – unit stopped by a fault
▪Init. heating – initial heating of the water heater, to prevent
from frost alarm during start-up
▪Service mode – unit ready to change basic settings like
application code
Note! That is initial factory setting of the controller. See
Advanced Manual for details.
▪Fast heating – special mode for recirculation, to ensure
quick heating up with max. possible recirculation
▪Overrun – special mode for stopping the unit if equipped
with electrical heater or DX-cooler, delays stopping the fan,
until safe conditions for the heat exchanger are established
Operation mode – used to set the main operating mode from
the HMI OPTIMA
▪Stop – unit stopped
▪Stage I – unit running, fans set to 1st speed
▪Stage II – unit running, fans set to 2nd speed
▪Standby – unit stopped to save energy, but ready for
automatic start up, to keep the main temperature within
specified safe range
▪Calendar – unit working automatically, according to the
real time clock settings
Temp. setting – setpoint for temperature regulator
▪Low limit: 5°C
▪High limit: 35°C
▪Default: 22°C

If the system did not start, check the F1 protection status
Correct device operation depends on the application settings. Choosing and setting
up the application should be done by qualified service provider, according to
recommendations of Advanced Manual

addresses occupied by several controllers
Communication period – gap between updating information
with the controller.
▪Low limit: 0.0s

HMI com speed / RS485M com speed – settings for
communication speed between the HMI and the controller. First
parameter refers to HMI speed, the other refers to the controller.
Note! The speed settings must match each other. Otherwise the
connection will be lost.
Observe communication speed in case of faulty connection.
See the electrical diagrams for the details.
LANGUAGE SELECTION English / Polski / Русский
HMI OPTIMA supports the following languages:
EN English
PL Polish
RU Russian
English is set as a default language.
Note! The alarm descriptions are always given in English.
