»INPUTS
Up to 2 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
If a window contact is enabled via the digital input, the reference will switch to a setback set point (Heat SP/Cool SP).
contact/Energy
hold off
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
Alarm contact
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.
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!
