Presentation of the regulator DRC 10

Parameter setting:: The regulator in full version can simultaneously control a cold ceiling, a fan coil unit, lighting in modulation and shutters. The different configurations can be obtained by simple parameter setting using the same tool. A light version, cheaper, meets the same functionalities as the full version except the shutters control.

Peripherals:

Many peripherals can be connected to the module:

The room and water temperature sensors be in 0-10V or NTC20K
The valve actuator can be in 220V or in 24V, pulse wide modulation, floating or modulation 0-10V
The fan may be controlled by the speed selection (1, 2 or 3) but can also be controlled by a modulated signal 0-10V

Assembly:: The DRC10 regulator can be assembled directly in a false ceiling or a false floor without adding additional case.

Peripherals:

For the temperature measurement, the module can work with inexpensive passive sensor NTC20KΩ.
For the condensation alarm, the condensation sensor is directly connected to regulator. No additional threshold module is necessary
During a building restoration, its great modularity makes it possible to keep the majority of the existing peripherals.

Parameter setting:: During the room arrangement or building conversion, the absence of programming allows a quick and easy setting of the regulator to be adapted to the new configuration.

Digital output technology:

All the digital outputs of the regulator, in 24V or 220V, are equipped with an electronic device. It enables the output when the supply voltage is null and release it when the current in the output peripheral is null. This device makes it possible to appreciably decrease the current’s peak and over voltage.
Quiet regulator: The absence of electromagnetic relay makes the DRC10 completely quiet. It can thus be installed in buildings such as hotel rooms, recording studios.

Checking of the correct behavior of the regulator:

Bus

The flexibility of the bus allows an integration of a great number of modules. Indeed not less than 3900 modules can be addressed simultaneously. The various segments, connected between them by amplifiers, can connect 200 modules over a maximum length of 1200 Mr.
The communication between regulators is done via the open protocol “Modbus” in RS 485. This choice allows a cheap wiring bus by using for example the cable “JHstH” without halogen. It also guarantees the quality of the communications thanks to an error rate practically nil.

Dew point calculation:: The regulator computes the dew point from the room humidity and temperature. If the value is higher than the water temperature injected into the cold ceilings, the module will close all its valves of cold. This technique avoids the needs of a window contact and, if necessary, allows it to anticipate condensation.

Operating schedule:: The regulator has an autonomous internal clock which can maintain the time even during an interruption of current for at least one week. Thanks to this clock, 3 operating schedules (for the regulation, lighting and the shutters) give the operating mode of the regulator. Each schedule offers up to 4 commutations per day.
