The reasons for choosing Robur heating and cooling systems
ROBUR
Integrated heating and cooling solutions with Absorption Heat Pumps powered by natural gas and renewable energies
ROBUR VALUES Mission Robur is dedicated to dynamic progression in research, development and promotion of safe, environmentally-friendly, and energy-efficient products, through the commitment and caring of its employees and partners Vision Robur turns THE LOVE FOR BEAUTY AND WELL-MADE THINGS into innovative heating and cooling systems that are especially designed and developed to answer the specific needs of Man 7 pillars Sharing values Training Quality Innovation Service Social responsability Testimony
The right choice can make the difference A responsible purchase behaviour may have a great influence on our way of life. Consider that a product consumes tons of oil during its whole life cycle, generating pollution that the forest cannot rebalance. That's why, when choosing a good, we take a great responsibility. Even the choice for the heating system may have a big impact. To all who choose responsibly, Robur offers high efficiency heating systems with low environmental impact, and moreover concepts, data and facts to spread the culture of energy efficiency and environmental protection.

Component Direct Digital Control (supplied as standard for pre-assembled links) 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). RoburBox100 (system control interface) 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. RoburBox200 (system control interface) RB200 (RoburBox200) is the control interface for systems made up of Robur chiller-heater units and/or absorption heat pumps, fitted with Direct Digital Control (DDC). On top of the same functionalities already provided by RB100, the device is designed to carry out the following additional functions: • integration of third parties appliances, i.e. in case of retrofitting of existing systems; • control of water circulation of primary and secundary circuits; • regulation of overall capacity and temperature set-point to improve overall efficiency. CCI Comfort Control Interface The CCI panel can control and modulate the power output of one or more GAHP-A, GAHP-GS and GAHP-WS, up to a maximum of three units. This in order to adjust the thermal output in accordance to the requirements coming from an external electronic regulator (0-10 Volt signal). CCI is then an interface panel, alternative to the DDC, connected to an outdoor temperature adjusting system, such as the RSI regulator for example. CCP (Comfort Control Panel) With the aim of delivering the maximum environmental comfort whilst minimizing the energy consumed, Comfort Control Panel makes it possible to integrate the operation of the entire heating system maximizing the overall efficiency. Comfort Control Panel is capable of managing: • up to 3 heat pumps E3 and the load on the E3 heat pumps with a climatic curve; • the monitoring of all units parameters and the circulation pumps as well; • secondary distribution to different zones and DHW production; • the anti-legionella cycle; • the integration with boilers and solar panels; • free-cooling; • the interface with a modem for remote assistance.

GAHP, GA, AY Line accessories Component Outdoor temperature probe for weather curve This probe is to be connected to the DDC or to the RSI (Integrate System Controller) and it allows the units to operate in the weather curve mode, that is adjusting the set-point of the outlet water temperature, both in heating and cooling, not to a fixed value but in relation to the outdoor temperature, detected by this outdoor temperature probe. CAN BUS cable connection For the connection between the Direct Digital Control and the Robur units. Circulation pump According to the installation characteristics and regulation settings, several different circulating pumps are made available, with fixed and modulating water flow. Winter kit for condensing boilers AY 00-120 This kit extends the operation of the boiler to an outdoor temperature of -30 °C through dedicated thermoregulating and heating devices to be fittable also on boilers already installed.
E3 systems components Component Zone valves complete with actuator Zone valve and three-way valve to be used to complete the secondary circuit.
Air separator and sludge remover filters to care for the system and protect it from downtime and/or malfunctions due to the presence of excess of air or dirt.
