»MOUNTING ADVICES
The housing of the module is designed for installation on standard DIN rails according to DIN EN 60715. For operation, a separate external 868
MHz receiving antenna is necessary.
The antenna has a magnetic flux and must be mounted in the middle of a metal plate with the minimum dimensions 180 mm x 180 mm (material:
galvanized sheet steel, please see “accessories”). The ideal mounting place in rooms is found approx. 1 m under the ceiling (optimum radio
transmission range). The antenna should be adjusted vertically downwards and should have a minimum distance of approx. 90 mm to the wall.
The distance to other senders (e.g. GSM/DECT/Wireless LAN/ EnOcean senders) should be 2 m at least. To match the colour of the room, the
antenna can be painted, accordingly (do not use any metallic lacquers).
Cable Laying Notice
•Cable laying should be made in an electric conduit.
•A cable crushing should be avoided.
•The minimum bending radius of the extension cable amounts to 50mm
•Do not use an active pull-up device for the cable laying, in order to avoid any damages of the sheathing respectively of the connectors.

»FUNCTION DESCRIPTION
The STC-DO8 compares the room temperature provided by the wireless sensor with the calculated set point. If the room temperature falls below
/ exceeds the calculated set point, the relays are controlled by the controller according to the corresponding device settings.
The receiver calculates the set point of the room temperature from the adjusted basic set point (default 21°C) and the set point adjustment (default
-5k…+5k).
The radio sensor cyclically sends a radio telegram with the measured values to the receiver. In normal operating mode, the reception of a taught-
in sensor is indicated at the receiver by a brief lighting up of the "RXD Radio" LED.
Energy Stop Function:
If a window contact or window handle is connected, the STC-DO8 can only switch on the corresponding heating-output if
•the information “window closed” is provided by the window contact/window handle,
•or no signal of the window contact is received in the recent 45 minutes (defective window contact)
•or “window opened” is reported by the window contact/window handle, but the room temperature has fallen below the antifreeze limit set
(default 8°C).
Function Comfort/Lowering Operation:
The STC-DO8 has an integrated time switch by which an automatic toggling from comfort to lowering mode or from lowering to comfort mode can
be effected. Thus, the time switch has 8 timer clocks, which can be assigned to each output/channel and every weekday.
Furthermore, it is possible to set the STC-DO8 manually into the lowering mode when using the room sensors SR04P MS / SR07P MS or up to 10
sensors of the digital input module SR65DI or wireless EnOcean switches.
When having connected the occupancy sensor (SR-MDS) or when using room sensors SR04T, SR04PT or SR04PST the comfort time adjusted
at the STC-DO8 can be prolonged.
Thus, it can be avoided that the temperature is switched down by the controller although the room is still occupied.
Comfort Operating:
In the comfort operation the set point of the controller is formed as follows:
Basic set point + local set point adjustment.
Lowering Operating:
In the lowering operation the set point of the controller is formed as follows:
Basic set point - lowering temperature
With the SR04P MS the switching-over is made by the slide switch (position 1 = lowering mode, position 0 = comfort mode).
As for the SR07P MS the switchingover is made by the slide switch (position night = lowering mode, position day = comfort mode). As for the SR65
DI the switchingover is made by the digital input for floating contacts (contact open = lowering mode, contact closed = comfort mode). As for the
EnOcean wireless switches, the switchingover is made by button actuation (Position 1 = comfort mode, position 0 = lowering mode).
Toggling between Heating and Cooling
Via a “change over sensor” an operating mode (heating or cooling) can be predefined to the STC-DO8. This is especially necessary for 2-pipe
systems, because there is only one valve for heating and cooling available. As a “change over sensor” the SR04P(S) MS (slide switch position 1
= cooling, position 0 = heating) SR65 DI (input open = heating, input closed = cooling) as well as the SR65 VFG (temperature falls below adjusted
switching threshold = cooling, temperature is greater than/equal to adjusted switching threshold= heating) can be used.
Switching Outputs
The STC-DO8 Fan Coil provides 3 to 5 switching outputs (depending on the number of required fan stages) with different functions. By means of
these outputs, lighting and blinds/shutters can be controlled.
The following functions are available: Universal, 1-button operation, 2-button operation, blind function, shutter function.
For further information, please see the following descriptions.

»FANCOIL CONTROLLER
PI-Controller
As for the PI-controller the control variable (Y) is calculated by means of the room temperature, the set point and the adjusted control parameter
Xp/Tn.
The control variable is output to the corresponding relay output in form of a pulse width modulation (PWM). The property setting of the PI-controller
[ (P) amplifying P-Band, (I) reset time Tn and the PWM period] can be field adjusted for each output in the configuration menu.
Fan Stages
By means of the calculated control variable as well as the definable switching thresholds, the fan stage is automatically set at the fan coil. Via the
manual operation on the sensor (SR04PST) the fan can be manually adjusted, as well.
Switching Outputs
Function Universal
The corresponding output is switched as soon as a switch-on command is received by one or several sensors. All sensors learned-in are logical
OR circuit linked. That is to say, as soon as any window contact SRW01 reports “window opened” or any digital module SR65 DI “contact closed”
or a multi ceiling sensor SR-MDS reports “occupancy” or a window handle reports “window opened or tilted” or an EnOcean wireless switch is
switched-on, the relay is switched. In reverse order, the relay is only deactivated, if the switch-off command is received from all sensors.
Function 1-Button Operation
The corresponding output is switched-on, as soon as the learned-in button of an EnOcean switch is pushed and automatically reset after expiry of
an adjustable after-run time (5 seconds…120 minutes).
If the after-run time is deactivated, the output switches-on as long as the button is released again (button operation).
If the after-run time is set to “continuously ON”, the output is switched-on after actuation of the learned-in button and is only switched-off when the
button is pushed again.
Function 2-Button Operation
The corresponding output is switched-on, as soon as the I-button of a learned-in EnOcean switch is pushed and is reset after actuation of the O-
button of a learned-in EnOcean switch.
Function Blind and Shutter
The outputs 5/6 (5: down, 6: up) and 7/8 (7: down, 8: up) can be used for controlling blinds and shutters.
Blind function: The output Up/Down is switched-on as long as the button Up/Down is pushed. If the corresponding button is pushed for more than
2 seconds, the output remains switched-on for the period of the adjustable after-run time (lock).
Shutter function: The output Up/Down is switched-on for the period of the adjustable after-run time if the button Up/Down is pushed. If the
corresponding button keeps pressed for more than 2 seconds and is released again afterwards, the output switches off immediately. The outputs
for “up” and “down” are locked back-to-back by the software, so that always only one relay is switched and a damage of the blind/shutter drive is
avoided.
During installation/wiring a wired interlock has to be included additionally according to the application example shown in this product sheet.

»CONFIGURATION
The STC-DO8 has 6 capacitive buttons which re-calibrate themselves automatically after a reset. In order to guarantee a smooth function of the
buttons, they must not be touched during calibration. Calibration is finished as soon as the green LED (power) shines continuously.
The STC-DO8 has a configuration menu via which any properties can be set. The menu is partitioned into 3 levels, whereas for operation each
level is exactly assigned to 2 keys.
Notice:
For menu items in which 1 value shall be changed (e.g. basic set point), the left button has the function "left/-" and the right button "right/+".
For menu items in which 2 values shall be changed (e.g. time including hours and minutes), the left button has the function "Value A +" and the
right button "Value B +".
For menu items in which more than 2 values shall be changed, the left button has the function "Selected value +" and the right button "Select
value".
Fancoil Controller
The fan coil controller is parameterized via the menu points “fan coil general & heating” and “fan coil cooling”.
Via “fan coil general & heating”, the settings for the heating function are made. In addition, settings which are valid for the heating and cooling
functions in the same way are determined in this menu point (learning-in/deleting of sensors, set point adjustment, night lowering, number of fan
stages, pipe system…).
Via “fan coil cooling” exclusively the settings for the cooling function are made and the “change over sensors” are administrated.
Parameterization of Outputs
The function that shall be parameterized can be selected by the function keys F1 and F2.
By means of the keys F3 and F4 the requested property can be chosen afterwards. With F5 and F6 the values can be changed.

Safety Code Input
In order to prevent an unauthorized setting of the parameters, the SRC-DO8 can be locked by a safety code.
After a restart or if none of the 6 buttons is actuated during the period of the LCD illumination, the next user is asked to insert the safety code when
trying to make new settings at the SRC-DO8.
Lock Parameterization
In order to avoid a change of the control properties by mistake after installation, the corresponding menu points can be locked. Due to the locking,
only the time switch as well as time and date can be programmed afterwards. To activate the locking, push the two upper buttons (F1 and F2) of
the switched-on STC-DO8 for 10 seconds until a tone of confirmation is heard. The unlocking is done in the same way.
»MSG-SERVER FUNCTION (TYPE STC-DO8 ONLY)
Function Principle:
The STC-DO8 with integrated MSG-Server functionality is designed as a gateway between EnOcean actuators (SAB05) and common EnOcean
based sensors (temperature, motion, window position etc.). The sensors are transmitting their values to the STC-DO8 time and event controlled
(e.g. current room temperature, set point, window status etc.). The STC-DO8 evaluates the data received and calculates the necessary control
variable (valve outlet). To enable a long lifetime of the batteries used in the valve actuator, the actuator is set into an energy saving mode (sleep
mode) and wakes up in a certain timer interval (wake-up time). If the valve actuator "wakes up", a specification request telegram is sent to the
STC-DO8. The STC-DO8 resends the new control variable (valve outlet) within 0,5s to the actuator. Afterwards the valve actuator starts the valve
position and is reset to the sleep mode.
The MSG-server function is available parallel to the control of conventional valve actuators. Accordingly, you can teach-in an EnOcean valve
actuator to an output, and simultaneously connect a conventional actuator to the corresponding relay. Both actuators are controlled in this case
with the same control variable.
»SUPERIOR CONTROL UNIT(FOR FANCOIL CONTROLLER)
In the STC-DO8, a higher-level control unit can be taught-in per output, with which the outputs can be overridden. This makes it possible to influence
and adjust the control of the STC-DO8 from a higher level.
Learning in of a superior control unit:
Set the corresponding output of the SxC-DO8 into the learning mode. A learn telegram of the superior control unit with the EnOcean profile EEP
A5-20-12 shall be sent within 60 seconds.
»STC-DO8 ENOCEAN TELEGRAMM (FANCOIL CONTROLLER - OUTPUTS 1...3-5)
The type STC-DO8 is able to transmit its current states via the EnOcean radio telegram in order to transmit an acknowledgement of the output
states to other EnOcean receivers.
For this purpose the integrated fan coil controller of the STC-DO8 has its own EnOcean ID, under which the STC-DO8 transmits a telegram
according to the EnOcean standard EEP A5-11-02.
The transmission interval is set in the "General" menu.
A 10, 100 and 1000 second interval can be selected.
Note: The set transmission interval varies by +/-20.
In addition to cyclical transmission, a telegram is sent each time the status of the outputs changes.
Note:
During a send action, all initial states are always transmitted. So if, for example, only one output changes, the remaining 7 output telegrams are
still transmitted.
Button F5 increases the selected number
by 1.
Button F6 selects the next number of the four-digit
code.
Button F3 confirms the input of the safety code.
Button F4 stops the input of the safety code.
