TERMS AND DEFINITIONS
Gitié ARAY Appliance / Unit = equivalent terms, both used to
designate the integrated package consisting of a GAHP-AR unit
and a AY00-120 condensing boiler.
GAHP Appliance/Unit = equivalent terms, both used to des-
ignate the gas powered absorption heat pump GAHP (Gas
Absorption Heat Pump).
AY00-120 Boiler / Unit = equivalent terms, both used to desig-
nate the AY00-120 condensing boiler.
TAC = Technical Assistance Centre authorised by Robur.
External enable = generic control device (e.g. thermostat, clock
or any other system) equipped with a voltage-free NO contact
and used as control to start/stop the GAHP/GA unit and the
AY00-120 boiler.
DDC Control (Direct Digital Controller) = optional Robur adjust-
ment device to control one or more Robur appliances (GAHP
heat pumps, GA chillers and AY00-120 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, circulators, probes).
Thermal generator = equipment (e.g. boiler, heat pump, etc..)
for heat production for 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/AR11 Boards = electronic boards on the GAHP unit, to con-
trol all functions and to provide interface with other devices and
with the user.
S70/AY10 Boards = electronic boards on the AY00-120 boiler, to
control all functions and to provide interface with other devices
and with the user.
