The comfort units are all equipped with V300 control.The comfort units, whether self-contained or controlled by a master/slave unit, have a wall-mounted terminal. A centralised timer, located in the electrical cabinet outside the zones, is used to manage all the comfort units throughoutUsers can: all (or part) of the building (distribution by floor or wings, etc.)- Change the setpoint,but only within the restricted range defined by the controller/zone timer, This timer includes an additional configured controller and a- Switch to Off mode by pressing the button, terminal connected to this controller. - Manually control the ventilation speeds, - Restart comfort mode, if the time slot set on the timer is This terminal is used to: programmed to switch the installation to economy/frost - Set the daily/weekly timer integrated in the module,protection/off mode. In this case, the restart time depends on the value authorised by the timer. - Distribute all the comfort units across 6 self-contained zones, - Determine, for each zone, the hourly management over 7 days of the 4 modes: comfort/economy/frost protection/off,Optionally, the "zone controller" can manage the installation's changeover,enabling this function to be centralised and - Set, for each zone: allowing 2-way valves to be used (e.g.for variable flow ► The heating and cooling comfort setpoints,hydraulic circuits). ► The heating and cooling economy setpoints, ►Override the time slots per zone,or forthe entireAn "advance" function can be activated to restart heating in building, winter when the outdoor temperature is low.
