(1) Zone timer terminal for daily/weekly time scheduling over 6 zones. (2) C/O: changeover sensor for 2-pipe reversible Heating/Cooling application in the case of a centralised changeover. (3) Return sensor for slave units: 2 possible control options via parameters: measured by the master. information (in the case of large open plan offices). (4) Contact inputs to override the installation in On/Economy/Frost protection or Off mode.
(5) By-passing the electric heaters on the comfort units. (6) 230V output for automatic operation control (On/off) of ancillary equipment (AHU, extractors etc.). (7) Outdoor temperature sensor option (activation limit for electric heaters on comfort units and/or advance heating restart). (8) RS-485 communication bus: 2 shielded twisted pairs for connection between controllers and the V300 terminal. See technical manuals N12-54 (V300 control) and N14-13 (V300 zone timer).
The comfort units are all equipped with V300 control. A centralised timer, located in the electrical cabinet outside the zones, is used to manage all the comfort units throughout all (or part) of the building (distribution by stages, blades etc.)
The comfort units, whether self-contained or controlled by a Master/Slave unit, have a wall-mounted terminal.
Users can: - 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, when the time slot set on the timer would switch the installation to Economy/Frost protection/ This terminal is used to: Off mode. In this case, the restart time depends on the value - Set the daily/weekly timer integrated in the module, authorised by the timer.
- Distribute all the comfort units across 6 self-contained zones, - Determine, for each zone, the hourly management of the 4 the modes (Comfort/Economy/Frost protection/Off) over 7 days, - Set, for each zone:
Optionally, the "zone controller" can manage the installation's changeover, enabling this function to be centralised and allowing 2-way valves to be used (e.g. for variable flow hydraulic circuits). An "advance" function can be activated to restart heating in winter when the outdoor temperature is low. Whenever the timer's "comfort switch" is operated, the comfort
units restart from their middle setpoints and "auto speed" to ensure the installation is operating uniformly - the key to energy savings. NOTE: contact us for more detailed technical information.
building. The "zone controller" is used to globally manage: - The setpoint offset range authorised locally in the zones, - Adjustment of the comfort restart time on the wall-mounted terminal.
