Direct Digital Control (DDC)

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;
• cascade control with advanced algorithm;
• set point control with sliding temperature, thanks to the climate curve function (with optional outdoor probe);
• 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).

Robur Box 100

RB100 (RoburBox100) is the control interface for systems made up of Robur chiller-heater units and/or absorption heat pumps fitted with Direct Digital Control (DDC). The device is designed to carry out three main 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.
