Power supply
When several BUS devices are supplied by one 24 V AC voltage supply, it is to be ensured that all “positive” operating voltage input terminals (+) of the field devices are connected with each other and all “negative” operating voltage input terminals (-) (=reference potential) are connected together (in- phase connection of field devices).
In case of reversed polarity at one field device, a supply voltage short- circuit would be caused by that device. The consequential short-circuit current flowing through this field my cause damage to it.

Therefore, pay attention to correct wiring.

CONFIGURATION VIA UCONFIG | MICROSD-CARD OR MODBUS

Configuration software
config | Windows 10 is required to use the config configuration software
The JOY room thermostat can be parameterized using the uConfig configuration software. An SD card is used to transfer the created configuration file to the device. For BUS devices, a live configuration can also be performed via the BUS interface.
The online installer for the configuration software can be found in our download center. The installer retrieves all necessary files and plug-ins from our web server. In this version, an update function is integrated in the software.

CONNECTION PLAN

Note: Parallel connection of the potential-loaded inputs is not permitted!
If the operating mode (change-over DI) of several devices is to be switched together by one contact, the potential-free 230V input must be used (DI2, only possible with the 230V version). It must be ensured that the same phase is used for jointly switched devices.

| ****

PI controller (0..10 V)

Fan stages (all types)
In automatic mode, the fan speed is linked to the controller. The assignment of the fan stage to the control (heating/cooling, only heating, only cooling) is freely selectable. To ensure that the fan motor starts reliably, a period can be configured in which the fan starts with maximal value. Using one or more time channels, the fan control has to be set per time channel and period. Via the touch surface, the user has the option to override the settings of the device every time. When the next time the channel starts, the fan speed is set to the configured value. The fan is set to automatic mode when the user changes the occupancy state (occupied↔unoccupied).

Heating/ cooling with PI-controller (PWM) (only 5DO and EC AO2DO)
The time response of the PI control loop depends on the control parameters xp for the proportional area and tn for the reset time of the integral range. In case of an error, the P portion immediately changes the position value proportionally to the error variable, while the integral portion takes effect after a certain time.

The resulting actuating variable is output as a pulse-width-modulated signal directly to the outputs.
Heating/ cooling with 2-point-/ 3-point-controller (only 5DO and EC AO2DO)
In the case of temperature control, the 2-point controller only knows the switching states heating ON and heating OFF. The 3-point controller also knows the switching state of cooling. Two – and three-point controllers work with a hysteresis.

Heating/ cooling with PI-controller (0..10 V) (only EC 3AO)
The time response of the PI control loop depends on the control parameters xp for the proportional area and tn for the reset time of the integral range. In case of an error variable, the P portion immediately changes the position value proportionally to the error variable, while the integral portion takes effect after a certain time.

The resulting manipulated variable is output as an analogue 0..10 V signal directly to the outputs.
EC Fan automatic mode with PI-controller (only EC 3AO and EC AO2DO) (for EC AO2DO with two-point/three-point controller, the temperature range for controlling the 0..10 V EC fan is parameterized separately)

The 0..10 V (0..100%) control of the fan is proportional to the calculated manipulated variable of the PI controller.
i.E.: Calculated actuating variable 65% → Fan control with 6,5 V Calculated actuating variable 22% → Fan control with 2,2 V

EC Fan manual with PI-controller (only EC 3AO and EC AO2DO)
Up to 5 steps (steps) can be set using the configuration software. The set number of steps is divided linearly to the manipulated variable of 0..100%.
i.E.: Max. steps (stages) = 5
Stage 1 = 20% | Stage 2 = 40% | Stage 3 = 60% | Stage 4 = 80% | Stage 5 = 100%

DISPLAY

FUNCTION DESCRIPTION – BUTTONS

On the touch surface, there are adjustment options for setpoint and fan speed regulation.
While pressing these buttons, the white ring-LED of the Power-button lights up for visual feedback.

3 seconds without any interaction, the display returns back to main screen.

Standby mode (not compatible with Keycard-switch function)
In standby mode the display and all outputs are switched off (controller deactivated). The frost and heat protection monitoring remains active. The Modbus registers can still be read out (e.g. room temperature).

DIAGNOSTICS MENU
To access the diagnostics menu, select the header in the startscreen of the parameter menu, and press the ENTER key. Here you will find various information, such as device type, software version, state of the inputs and outputs and controller state (current manipulated variable).

PARAMETER MENU – MODBUS INTERFACE
The configuration menu is activated by simultaneously pressing the buttons “up” (A) and “down” (C) for at least 5 seconds.
The menu is enabled during the first 60 minutes after switching on the supply voltage as long as the device is not actively involved in Modbus communication. As soon as the device receives a valid request addressed to the device from a DDC, access to the menu is blocked. Without valid communication, access is blocked after 60 minutes!

INFO: Access to the menu can be protected with a password via Modbus. The login remains unlocked in the EnOcean menu until 10 minutes after the last key press. Default password: 2030

More detailed information for the configuration of the EnOcean channels can be found in the specification.
There are 20 channels available that can be assigned different functions. A channel can be configured as a receive channel, as a send channel or as a message server (SAB communication).

6 channels can be configured with the SAB valve actuator, one of these can be set with the bath function. For the SAB with the bath function, an additional setpoint offset can be set. If SAB valve actuators are learned in, the analog outputs to the internal controller remain active and can also be used.

FUNCTIONAL OVERVIEW SAB

The profiles used are divided into functional groups:

SRW/SRG| Window contact and window handle. Both have an influence on the window contact function and are linked to the digital inputs or the Modbus default. Up to five sensors can be learned-in.
---|---
VFG| Sensor for chngeover control. Only one changeover sensor can be learned in.
EXT/WRF| Receiving channel: Temperature preset by an external room temperature sensor. Overrides the internal temperature sensor. Max. one sensor can be learned in. An EnOcean room operating unit is displayed on the send channel.
OCC| Up to 3 motion sensors can be learned in and affect the occupancy function. The last changed value (Modbus,EnOcean, Button) will be accepted. If several EnOcean motion sensors have been learned-in, the “ROOM UNOCCUPIED” value will only be accepted once all sensors have signaled “ROOM UNOCCUPIED”.
KEY| Controls the internal keycard function. When learning a key card switch, the card must not be plugged in AND pulled immediately during the learn-in process. It is necessary to wait at least 5 seconds until the second action is performed with the card. Only then will the switch be assigned as key card switch, otherwise it will be learned in as a radio rocker switch (function group RPS).
SUP| A superior control unit to override the internal functions.
SAB

(5+1 Bath)

| Up to 6 SAB´s can be learned in. One pcs. can be assigned with the „Bath“ function. The other channels can be used optionally for heating or cooling. For each SAB channel, an offset for the setpoint can be configured via Modbus.
OUT| Only in direction of transmission. A controller status (A5-11-02) every 15 minutes (configurable) and with every change of any value.
