most of the products may contain valuable materials that should be recycled and not disposed of as domestic waste.
Please note the
relevant regulations for local disposal.
»MOUNTING ADVISE ROOM SENSORS
The Accuracy of the room sensors are influenced by the technical specifications as well as the positioning and the installation type.
During Assembly:
•Seal mounting box (if present).
•Installation type, air draught, heat source, radiation heat or direct sunlight can affect the measurement.
•Bulding material specific properties of the installation place (brick-, concrete-, partition wall, cavity wall, …) can affect the measurement.
(e.g.: Concrete accepts room temperature variation slower than cavity walls)
Assembly not recommendet in…
•Air draught (e.g.: close to windows / doors / fans …)
•Near heating sources,
•Direct sunlight
•Niches / between furniture / …
»MOUNTING ADVICE JOY
Plasterboard boxes shall be covered by wall paper or paint to avoid that the plasterboard box's front rim will be partially visible underneath JOY.
Maybe consider using white plasterboard boxes (i.e. Kaiser 9063-77).

»FUNCTION DESCRIPTION – CONTROLLER
JOY HC AO2DO (85..260 V ~) JOY HC 3AO (24 V ~/=)
PI controller (PWM) &
2-point/3-point controller
(configurable)
PI controller (0..10 V)
6WV (PI-controller 0..10 V) (all types)
The manipulated variable is output as a proportional control signal at the output for the 6-way valve. The type of valve used is set via the
configuration software. You can choose from 2..10 V / 2..10 V INV (Belimo), 0..10 V DN15 / DN15 INV, DN20 / DN20 INV (Sauter). There is also
the possibility of a freely parameterizable 6-way valve (generic 6WV).
Heating/ cooling with 2-point-/ 3-point-controller (only HC 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 controller work with a hysteresis.
Heating/ cooling with PI-controller (PWM) (only HC 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 PI-controller (0..10 V) (only HC 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.

or Presence key*
*If the key is used as a
presence key at the same time,
the key must be pressed for at
least 3s, in all other cases a
short press is sufficient.
3 seconds without any interaction, the display returns back to main screen.

»MENU → TIME CHANNELS
In the Time Channels menu, setpoint and timer can be set. Up to 3 time channels with 4 time periods each can
be parameterized. The time channels are prioritised. Channel 3 has the highest priority. After selecting the line
of the time channel to
be edited, the next submenu is called up with the "Right" key. It is possible to set any
time period within one week in the first two lines with the "Left" (-
)/ "Right"(+) keys. In addition, the ECO mode
is available in the menu sections. In ECO mode, the
dead zone between heating and cooling is automatically
set to the ECO dead zone configured in the "General Settings" menu (default: 10 K).
»MENU → INPUTS
Up to 3 inputs are configurable for functions such as windows contact, dew point, occupancy, change-over or
external sensor option.
The overview of possible combinations can be found in the software specification of the JOY.
Sensor (NTC10K)
The value of an external sensor will be shown if connected and configured accordingly. In this case, the room thermostat
controls according to the external sensor. Alternatively, an external temperature sensor can be used at the universal input
to protect floor heating. If a configured temperature is exceeded, the heating sequence is suspended.
Change-Over DI
Which controller is active depends on the state of the Change-Over contact. (Factory default: contact open heating controller
active, contact closed cooling controller active). The terminals 4 and 5 are used as outputs for heating rsp. cooling.
Change-Over
Sensor
The Change-Over Sensor is used for switching between heating and cooling mode automatically. If the temperature is below
22 ° C, the controller is in cooling mode. If it is above 25 ° C, it is a heating mode.
If an input is configured as a change-over, the room thermostat is automatically in 2-
pipe operating mode and both outputs
(terminals 4 and 5) are used as outputs for heating rsp. cooling.
Window
contact/Energy
hold off
If a window contact is enabled via the digital input, the reference will switch to a setback set point (Heat SP/Cool SP).
Dewpoint
An active dewpoint contact locks the cooling controller.
Occupancy
If occupancy-function is active, the symbol will be displayed automatically. In state of “unoccupied” the heating set point is
reduced by 2K (default setting) rsp. the cooling set point raised by 2K.
Keycard-Switch
When the card is not inserted, the device is switched in sleep mode. Operation of the keys is locked, the display is switched
off and the controller adjusts to the nominal values of the "unoccupied"-State.
Alarm contact
An alarm symbol can be shown in the header of the display. The backlight flashes when the alarm is active. This symbol is
in the same position as the ECO symbol. The alarm symbol has a higher priority and overwrites the ECO symbol!
»MENU → TIME/DATE
Time, Date and display format can be configured in the menu settings. The room thermostat is equipped with
a real-time clock so that it automatically adjusts for daylight-
saving time. This function can be disabled in the
datetime settings.
»MENU → SENSOR SETTINGS
Offset correction for internal and external sensor value.
The temperature display can also be changed from °C to °F.

Valve protection
A valve protection function actuates the heating and
cooling valves
regularly to prevent locking during non-usage times.
The function is executed fridays
at 11.00 (heating valve) and 11.15
(cooling valve).
The corresponding valve is triggered for 5 minutes, if not
activated during the last 96 hours.
ECO deadband
The dead band can be adjusted (default 10.0 K)
* further information in the software specification file
Factory setting
By selecting “Factory setting”, the room thermostat will be reset and
