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 of time can be configured in which the fan starts with maximal value. Using one or more time channels, the fan control have to be set per timechannel and per period. Via the touch surface the user has the option to override the settings of the device every time. When the next time 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 controller work with a hysteresis.

Heating/ cooling with PI-controller (0..10 V) (only EC 3AO 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 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 parameterised separately) The 0..10 V (0..100%) control of the fan is proportional to the calculated manipulated variable of the PI controller. example: 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 (stages) can be set using the configuration software. The set number is divided linearly to the manipulated variable of 0..100%. example: max. steps (stages) = 5

• Stage 1 = 20% Stage 2 = 40% Stage 3 = 60% Stage 4 = 80% Stage 5 = 100%
• max. steps (stages) = 3
• Stage 1 = 33% Stage 2 = 66% Stage 3 = 100%

• Open sub menu (right) In the header left to leave the submenu
• Confirmation

DIAGNOSTICS MENU

To access the diagnostics menu, select the header in the start screen 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

Access to Parameter menu
Press buttons for 3 seconds simultaneously

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 prioritized. 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.

 

MENU → COMMON SETTINGS

Common device settings:

• Brightness
• Valve protection
• ECO deadband
• Fanstages (5DO only)
• Language
• Factory setting (reset)
