1. DESCRIPTION
Stouch controller is specially designed for control of:
• Heat recovery systems, where control boards PRV_V21, EKR, MCB or ECO_v1072are installed;
• Air supply, exhaust units when automatic control is used with ECO_v107 controller;
• Fans with EC motors³;
• Devices which are controlled using Modbus protocol.
1Units: RIS/RIRS 3.0; RIS/RIRS EKO 3.0
2Units: RIRS 200 VER EKO; RIRS 300 VE... EKO
3Using the remote controller “Stouch” for “ECO” fans’ control it is necessary to use additional power
supply and to provide the protection against overloads and/or short circuits.
NOTE: Remote controllers don’t control cooker hoods separately with following units:
RIRS 200 V EKO with “Aut. RIRS-200VEEC-...k (+ 15..25 oC)” automatics;
RIRS 300 V EKO with “Automatika RIRSV 300 VE” automatics.
This function is possible only with the units that have integrated automatics.
Remote controllers ensures comfortable operation, monitoring, maintenance and safety. All opera-
tions are performed remotely by using controller, which shows fault reports and maintenance con-
ditions.
Features:
• Exceptional and ergonomic design;
• Casing: plastic;
• Screen: tempered glass;
• Easy operation;
• Surface mounted;

• Selecting 4 preset speeds;
• Selecting percentage value of speed (0,20 - 100 %) only for 0...10 VDC output and ECO controller;
• User menu speeds are set in intervals of 5 %;
• Service menu speeds are set in intervals of 1 %;
• Operates in 4 speeds, the values of which are displayed on Stouch in Pascals (Pa).
NOTE: the function is available when fan and pressure sensor are connected to Stouch.

10 | EN STOUCH v2019.1
• Maximum ventilation. The unit operates in maximum speed (according to boost conguration).
Maximum speed is limited by timer which can be easily set (see table);
• Maximum speed can be activated using fast button. When preset maximum fan speed (boost)
time is over, previous speed is automatically restored;
• 0..10 VCC CO2sensor can be connected for activation of maximum speed based on the given
CO2parameters.
9. TEMPERATURE
• Temperature from 15 to 30 C may be set by remote controller. Note: Temperature of MCB control-
ler can be adjusted from 0 up to 40C (it depends on MCB settings).
• Supply air and set temperatures can be displayed interchangeably (set temperature is displayed
for 5 seconds, then supply air temperature is displayed for 2 seconds)
10. REMOTE CONTROL (MODBUS)
Controller supports fully congurable Modbus interface. Panel can operate as master and slave
device in modbus network and also it can be fully controlled and congured not only via service
menu but also via modbus interface.
11. USER MENU
In order to reach user menu, press down B2 and B3 for 3 seconds.
In user menu, menu items (P.01, P.02 etc.) settings are displayed sequentially. Menu item is select-
ed using elements B4 and B6. After pressing B5, value of selected parameter is shown and can be
changed using elements B4 and B6. Press B5 to save the parameter and to return to menu.
Due to limitations of segment display, values of P.04 and P.05 are shown divided by 10, i.e. if 20 is
displayed, it means that real value is 20 x 10 = 200.
P.06 - Filter timer resets by pressing B2 and B3 for more than 5 seconds. Filter timer also resets
by clearing fault signal.

Desired pressure can be maintained by connecting 0..10 VDC fan and 0..10 VDC pressure convert-
er directly to the controller. Control and pressure sensor parameters can be changed in controller.
When controller is used as Modbus slave device (air handling unit is not controlled by this principle),
it allows controlling all parameters and monitoring of pressure sensor readings.
For pressure based control, select the following parameters in the service menu:
F.01 - 2
F.14 - 1
F.15 and F.16 - based on pressure converter parameters
F.11, F.12 and F.13 - (PID control ratios). If pressure is maintained incorrectly, these parameters
can be adjusted.

This controller allows controlling level of carbon dioxide (CO2) in a room. Connect 0..10 VDC CO2
sensor directly to the controller and congure the controller. In service mode, in item F.14 set 2, and
F.15 and F.16 should be set based on the sensor specication.
After CO2sensor is connected and required parameters are set in the service menu, select desired
CO2level (P.05) and allowed di󰀨erence from the set (P.05) limit in the user menu. If allowed di󰀨er-
ence is exceeded, controller will automatically start fans at maximum (4) speed and “CO2” will be
shown in digital display. After set CO2level (P.05) is reached, controller will return to previous mode.
NOTE: The air quality converters and remote controller (when fan is controlled) must be powered
from a separate power source. It is not supplied with the remote controller.
13. SERVICE MENU
To enter service menu:
1. Go to “Off” state (if controller is on, press down element B1 for 3 seconds).
2. Press down B1 and B2 for 3 seconds.
3. Using elements B4 and B6, enter security code “022” and conrm with element B5.
In the service menu, settings of menu items (F.01, F.02 etc.) are shown sequentially. Menu item is
selected using elements B4 and B6. After pressing B5, value of selected parameter is shown and
can be changed using elements B4 and B6. Pressing B5 saves the parameters and returns to the
setting menu.
To exit the service menu, press down element B1 for 3 seconds (controller goes to switch o󰀨 state).

entered as HIGH and LOW bytes in hexadecimal (HEX) system. Using buttons B2 and B3, select
HIGH or LOW bytes, “H.00” and “L.00” are displayed respectively.
14. MODBUS REGISTER READ AND RECORD TOOL
Modbus register read and record tool indicated in F.39 and F.40 items is useful when you want to
set the unit‘s parameters, which by default are not controlled by remote controller, but these param-
eters are accessible via Modbus. F.39 is used for Holding type registers and F.40 used Coil registers.
Using the Tool:
1. Modbus register address is indicated and conrmed by “MAX” button.
2. The tool reads the address value and shows on a segmental display (the value ashes).
3. Change the value with “+” and “-” button and conrm with the MAX button.
4. The tool records the value to indicated register and return to the service menu.

15. AIR FLOW HANDLING TOOL
Service menu F.45 is used to adjust air ow for di󰀨erent modes. Air ow handling tool operates with
MCB and PRV controllers.
Tool operation instruction:
1. Select desired air ow, what you want to control: SF.1, SF.2, SF.3, SF.4, EF.1, EF.2, EF.3or EF.4.
(SF and EF determine, for which fan airow will be modied; SF – air supply fan, EF – air exhaust fan.
Number determines speed/mode, for which air ow will be modied).
2. Equipment switches to the mode/speed, what was selected. Value from the controller is shown
on the split screen.
3. By pressing B4 and B6 you may change values (from 0 up to 100%). Fans speed/airow changes
automatically.
4. By pressing B5 you may exit airow handling tool. Adjusted settings are saved on controller.
5. In order to change other airow setting, please repeat steps 1-4.
16. STOUCH CONTROL PANEL AND OTHER MODBUS DEVICES MAY
NOT WORK PROPERLY WHEN PRV AUTOMATION IS ON THE COMPAT-
IBILITY MODE.“COMPATIBILITY MODE” CAN BE TURNED OFF WITH
STOUCH CONTROL PANEL:
1. Go to Service menu item F.40 (Modbus Coil read / write tool). How to enter service interface is
described in Stouch technical manual.
2. Specify address 21 and press “MAX” (indicate “Compatibility mode” Modbus register)
3. Set “0” and press “MAX” (“1” - on, “0” - o󰀨)
