Deva KNX

Description:

The DEVA room temperature controller is a KNX S-mode device for the independent temperature regulation of a room or a zone in a building. In combination with one or more KNX actuators, the room temperature controller is able to control the heating and cooling emission of a series of terminal units for the thermal exchange (such as radiators, fan-coils, foor and ceiling radiant panels, etc.). The device is provided with a LC-display with adjustable backlight and a sensor for room temperature measurement. The device is equipped with an integrated KNX bus communication module and is designed for wall installation on a fush mounting box. For the thermostat functions the integrated capacitive pushbuttons are used located on both sides of the display active area. The device is powered by the KNX bus line and does not require any auxiliary power supply.

Characteristics:

Main function:

· Temperature measuring through integrated sensor with possibility of sending the value on the bus

· 2-point (on/off) or proportional (PWM or continuous) room temperature regulation

· Ventilation control with continuous or 3-speed regulation

· Seasonal modes: heating and cooling with possibility of local or via bus seasonal changeover

· Operating modes: comfort, standby, economy and building protection with different setpoint for heating and cooling

· Manual or automatic control of fan-coil units with 2 or 4-pipes hydraulic distribution

· Displaying of measured and setpoint temperature (as °C or °F), alarms and errors (with alphanumeric coding)

· Window opening reporting

Additional functions are available receiving status or measured values via bus from other KNX devices:

· Weighted average of two temperature values

· Humidifcation and dehumidifcation control

· Automatic switching of the operating modes depending on presence or window opening

· Floor temperature limitation and antincondensation (for radiant panels)

· Antistratifcation function

· Automatic switching between operating modes through card holder contact

· Delayed start of a fan ("hot-start") with time-scheduling or depending on the water temperature measured at the coil for thermal exchange

· Displaying of external temperature

· Sending on the bus of the condition internal or external with regard to a confgurable comfort area

· Calculation of psychrometric values (dew-point temperature and perceived temperature)

· Displaying of relative humidity (measured and setpoint in %)
