eTR102

The room temperature controller for the KNX building bus system automatically controls air conditioning with fan coil units. It has touch-sensitive buttons with which the room climate settings can be manually readjusted. The fan speed (1-3), the setpoint temperature (value, touch buttons +/-) and the mode (automatic on/off, air conditioning on/off) can be set. LEDs show the current settings. The brightness and switch-off behaviour of the LEDs can be adjusted.

A temperature sensor is integrated in the unit, which can be used for control. To obtain a mixed value, the unit can receive another measured value via the bus and process it with its own value to obtain an overall temperature.

The automatic room climate control includes a PI controller for a heating and a cooling (one- or two-stage). This control contains parameters specifically for air conditioning with fan coil systems (systems with fans).

The room temperature controller can also be used as an extension unit, i.e. it transmits the manual inputs to another control device in the KNX system, which then takes over the control.

Communication objects can be linked in integrated AND and OR logic gates.

FEATURE:

• Operating area for setting 3 fan speeds
• Operating area for temperature control with 2 surfaces (+ warmer, - cooler)
• Operating area for mode setting with 2 surfaces (automatic on/off, air conditioning on/off)
• The lighting behaviour of all LEDs is adjustable, so they can be used as ambient lighting or switched off, for example.
• be used as ambient lighting or switched off as long as there is no no input takes place.
• Temperature measurement. Mixed value from own measured value and external values (proportion can be set as a percentage), output of minimum and maximum values
• PI controller for heating (one or two-stage) and cooling (one or two-stage) by temperature. Control according to separate setpoints or base setpoint temperature. Parameters specifically for fan coil control for Fan coil units
• 2 AND and 2 OR logic gates with 4 inputs each. The inputs for the logic gates, 8 logic inputs can be used in the form of communication objects. Can be used as inputs for the logic gates. The output of each gate can be configured either as 1 bit or 2 x 8 bits
