PRO System Line RTHF Series
The unit consists of a gas absorption chiller and a gas absorption chiller with heat recovery.
Digital Direct Control (supplied as standard for modular unit)
A single device to adjust, control and completely manage the unit's operation.
Functions include:
• allows the management of up to 16 modules (individual or pre-assembled) connected on the same hydraulic circuit and up to 48 modules, if connected to another two panels;
• programming of operation in cooling and/or heating on 4 time bands with differentiated water temperatures;
• control of the system's hot and cold inlet and outlet water temperatures;
• modular unit management;
• ability to have the system switched on and off through an external control device;
• visual and acoustic signalling of operating alarms for each individual unit;
• chronological display of alarms triggered;
• designed for connection to remove signalling systems;
• supports Mod-Bus RTU communication protocol for interface with BMS (building management systems).
RoburBox100 (system control interface)
RB100 (RoburBox100) is the system control interface for systems made up of Robur chiller-heater units and/or absorption heat pumps fitted with Digital Direct Control (DDC).
The device is designed to carry out three separate functions:
• interface in between the DDC and any external control devices such as regulators (even centralised), electronic thermostats, clean contacts, to give them the ability to control the enabling or disabling of hydronic circuits and of setting default set points for the water temperature;
• processing of a maximum of four requests; one for cooling, one for heating and two for DHW production; • interface for switching the 3-way valves, such as those for switching from cooling to heating typically located in annual cycle systems with 2-pipe water distribution.
WISE (Web Invisible Service Employee) is the remote communication system that manages, controls and supervises Robur systems fitted with a Digital Direct Control remotely.
