Temperature control central unit


This central unit can manage temperature control systems up to 99 zones, set the system and modify the system operating mode. It is more complete than the 4-zone flush mounted version; in fact just with item 3550 it can manage the magnetic contacts installed on the window frames to activate the energy-saving function (switching OFF the zones affected by any changes of air). Equipped with management software with guided menus shown on the display, it allows the user to chose the operating mode, display the temperatures of the various zones and display and modify the daily temperature profiles and the weekly programs, while the maintenance menu, reserved for the installer (password protected), allows access to the system settings (zone configuration, system test, total reset, etc.). The Central unit can provide both heating and cooling and can manage up to 99 different zones (with one Master probe for each zone plus possible Slave sensors) and up to 9 circulation pumps. A contact can be connected in input for remote control by means of a telephone actuator to switch from the anti-freeze mode to the automatic mode and vice versa (function not available with item HC/HS4695 and item L/N/NT4695 and AM5875).
