I INTRODUCTION
Manual
This Manual is an integral part of the GAHP-A unit and
must be handed to the end user together with the
appliance.
Recipients
This Manual is intended for:
▶
end user, for appropriate and safe use of the appliance;
▶
qualified installer, for correct appliance installation;
▶
planner, for specific information on the appliance.
Control device
In order to be able to work, the GAHP-A unit needs a control
device (DDC, CCP/CCI or external requests), which must be con-
nected by the installer.

II�2 TERMS AND DEFINITIONS
GAHP Appliance/Unit = equivalent terms, both used to des-
ignate the gas powered absorption heat pump GAHP (Gas Ab-
sorption Heat Pump).
TAC = Technical Assistance Centre authorised by Robur.
External request = generic control device (e.g. thermostat,
clock or any other system) equipped with a voltage-free NO con-
tact and used as control to start/stop the GAHP unit.
CCI Controller (Comfort Controller Interface) = optional adjust-
ment device Robur which lets you manage up to three modulat-
ing heat only GAHP units (A, WS, GS).
CCP Controller (Comfort Control Panel) = adjustment device
Robur which lets you manage in modulation mode up to three
GAHP units and all system components (probes, diverter/mixing
valves, circulating pumps), including any integration boiler.
DDC Control (Direct Digital Controller) = optional Robur device
to control one or more Roburappliances (GAHP heat pumps, GA
chillers and AY boilers) in ON/OFF mode.
RB100/RB200 Devices (Robur Box) = optional interface devices
complementary to DDC, which may be used to broaden its func-
tions (heating/cooling/DHW production service demands, and
control of system components such as third party generators,
adjustment valves, circulating pumps, probes).
Heat generator = equipment (e.g. boiler, heat pump, etc..) pro-
ducing heating and/or DHW.
GUE (Gas Utilization Efficiency) = efficiency index of gas heat
pumps, equal to the ratio between the thermal energy pro-
duced and the energy of the fuel used (relative to LCV, lower
calorific value).
First start-up = appliance commissioning operation which may
only and exclusively be carried out by a TAC.
S61/Mod10/W10 Boards = electronic boards on the GAHP unit,
to control all functions and to provide interface with other de-
vices and with the user.
