Water control Proportional-Integral V300
Eubac certified/AA energy labelling
A (3-wire) serial communication bus connects the Master unit to its primary slave, then connects the primary slave to the secondary slave, and so on. The Master communicates the following information to the slaves: setpoints, air and water temperature, current mode, window switch state. A wall-mounted radio-frequency terminal is available on sites which do not allow wiring (renovation projects etc.). The installation can be managed using a centralised zone timer located in a distribution box.
CIAT's V300 electronic networked control is designed for use with system-powered comfort units (ductable units, cassettes, AHUs etc.) in 2-pipe, 4-pipe, 2-pipe + 2 wire applications using recirculated air. It is available in a water control version with actuation of the 230V thermo valves in chrono-proportional mode. The V300 control is available in a factory-fitted, built-in comfort unit with a standard wall-mounting or a low wallmounting version to be connected by the installer. The V300 control performs a Master/Slave function to manage the comfort units installed in meeting rooms or large spaces (e.g. open spaces, lobby).
The V300 is a proportional-integral control. It controls the valve(s), the electric heater and the ventilation speeds. It has an option to select manual or automatic control of the ventilation speed. All the control parameters are factory-set, but these can be changed on site (using the LCD room terminal) to adapt to the constraints of individual sites. The factory-set comfort setpoints are +19°C for heating (adjustable) and +26°C for cooling (adjustable) with a range of +/-4°K (adjustable from +/-1°K to +/- 9°K). The control automatically manages the CIAT HEE motors to optimise the energy performance of our comfort units. The LCD room terminal is used to adjust the setpoint temperature in the predefined range, to select on/off and the desired ventilation speed. Two configurable inputs are used to control the window switch, if applicable, condensate pump faults, Economy mode etc. The controller has 4 operating modes: Comfort/Economy/ Frost protection and Off. These modes: Comfort (+19°C for heating + 26°C for cooling, adjustable), Economy (+14°C for heating +28°C or cooling, adjustable), Frost protection (+8°C) and Off are activated by a dry contact input (to be connected to a programmable timer in a shopping centre for example, or using a key). A centralised zone timer, to be located in a distribution box, may be used to automatically control the 4 operating modes of your installation over 6 self-contained zones. See our manual for more detailed information.
