I. SAFETY
Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules
included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe
place for further reference. In order to avoid accidents and errors it should be ensured that every person using the device
has familiarized themselves with the principle of operation as well as security functions of the controller. If the device is
to be sold or put in a different place, make sure that the user’s manual is there with the device so that any potential user
has access to essential information about the device.
The manufacturer does not accept responsibility for any injuries or damage resulting from negligence; therefore, users
are obliged to take the necessary safety measures listed in this manual to protect their lives and property.
WARNING
High voltage! Make sure the regulator is disconnected from the mains before performing any activities involving
the power supply (plugging cables, installing the device etc.).
The device should be installed by a qualified electrician.
The regulator should not be operated by children.
WARNING
The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply
during storm.
Any use other than specified by the manufacturer is forbidden.
Before and during the heating season, the controller should be checked for condition of its cables. The user
should also check if the controller is properly mounted and clean it if dusty or dirty.
Changes in the merchandise described in the manual may have been introduced subsequent to its completion on October
4h 2017. The manufacturer retains the right to introduce changes to the structure. The illustrations may include additional
equipment. Print technology may result in differences in colours shown.
Care for the natural environment is our priority. Being aware of the fact that we manufacture
electronic devices obligates us to dispose of used elements and electronic equipment in a
manner which is safe for nature. As a result, the company has received a registry number
assigned by the Main Inspector of Environmental Protection. The symbol of a crossed out
rubbish bin on a product means that the product must not be thrown out to ordinary waste
bins. By segregating waste intended for recycling, we help protect the natural environment.
It is the user's responsibility to transfer waste electrical and electronic equipment to the
selected collection point for recycling of waste generated from electronic and electrical
equipment.

II. DEVICE DESCRIPTION
VER-24 S regulator enables convenient control of Verano fan-coil.
VER-24 S offers the following functions:
Room temperature control (heating/cooling)
Smooth control of fan speed
Smooth control of the actuator (0-10)
ON/OFF actuator control
Daily schedule
Alarm clock
Parental lock
Controller equipment:
Built-in temperature sensor
Control output 0-10V DC for electronically commutated fan (EC)
Control output 0-10V or ON/OFF (24V actuator)
VER-24S controller enables the user to disable the fan manually during operation in heating mode (when the thermostatic
valve is open).

III. INSTALLATION
The controller should be installed by a qualified person.
WARNING
Risk of fatal electric shock from touching live connections. Before working on the controller switch off
the power supply and prevent it from being accidentally switched on.
VER-24 S regulator is intended to be installed on the wall.
First, attach the back cover to the wall in the place where the room regulator in the electrical box will be installed. Next,
connect the power supply wires and mount the device on the latches.

NOTE
In order to remove the back cover, disconnect the tape between the printed circuit board and the regulator.
IV. PRINCIPLE OF OPERATION
VER-24 S controls the fan and the valves in order to maintain the pre-set room temperature. Depending on selected
operation mode, the device may increase the temperature (heating mode) or decrease the temperature (cooling mode).
It controls smoothly the fan operation (increasing or decreasing its speed when needed) and the valve operation
(increasing or decreasing the level of valve opening depending on current needs). Additionally, the device may be used
to control another valve by opening it or closing as needed.

V. MAIN SCREEN DESCRIPTION
The main screen displays current status of basic controller parameters.
1. Day of the week and time
2. Operation mode change:
- Heating–sun icon
- Cooling –snowflake icon
NOTE
This function is active when Manual heating/cooling option is selected in the service menu, in Mode
selection submenu. If any other mode is selected, the mode change icon is not displayed; instead the
upper right-hand corner of the screen displays an icon indicating current operation mode.
3. Current controller operation profile
4. Additional sensor temperature
5. Current pre-set temperature (depending on selected profile and operation mode)
6. Fan speed
7. Fan mode change icon. The fan may operate in the following modes:
- Automatic –fan speed is controlled with the controller operation algorithm
- Manual –three speed levels
- Off
NOTE
Information about current fan operation mode is saved in the controller memory 6 seconds after the
last parameter change.
8. Opening degree of a smooth control valve

VI. CONTROLLER OPERATION MODES
Regardless of the selected profile, the controller may operate in two modes: heating or cooling. In Service settings/Mode
selection submenu the user configures mode selection. The user may select one operation mode - by selecting heating
or cooling or allow manual mode change from the main screen view - by selecting Manual heating/cooling.
NOTE
In order to unlock Service settings function, it is necessary to enter a four-digit PIN code: 5162.
Operation mode Heating
Once this mode has been selected, when the controller detects that the room temperature is lower than the pre-set value
(setting in Temperature settings submenu), it activates the fan and the valves in order to raise the temperature. When
the room temperature reaches the pre-set value minus user-defined value (setting in Service menu/Temperature
settings), the controller gradually starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
Operation mode Cooling
Once this mode has been selected, when the controller detects that the room temperature is higher than the pre-set
value (setting in Temperature settings submenu), it activates the fan and opens the valves in order to decrease the
temperature. When the room temperature drops to the pre-set value plus user-defined value, the controller gradually
starts decreasing the fan speed and closing the valve.
Once the pre-set room temperature has been reached, the fan is disabled and the valves are closed ( fan automatic mode
is active).
VII. CONTROLLER FUNCTIONS
During standard controller operation, the display shows the main screen. By pressing menu button the user may configure
controller functions.
Due to controller complexity (a wide range of configurable parameters), the controller menu is divided into the main
menu and the service menu secured with a 4-digit code. The main menu includes basic controller parameters such as
operation mode, pre-set temperature setting, main screen view etc.
