1.6 CONTROLS
Control device
The appliance may only work if it is connected to a control de-
vice, selected from:
▶
(1) pre-configured DDC control
▶
(2) external enables
1.6.1 Adjustment system (1) with pre-configured
DDC control
The main functions are:
▶
Adjustment and control of the GAHP/GA unit and AY00-120
unit in cascade (ON/OFF mode).
▶
Data display and parameters setting.
▶
Hourly programming.
▶
Climatic curve control.
▶
Diagnostics.
▶
Errors reset.
▶
Possibility to interface with a BMS.
DDC functionality may be extended with auxiliary Robur devices
RB100 and RB200 (e.g. service requests, DHW production, Third
Party generator control, probe control, system valves or circulat-
ing pumps, ...).
1.6.2 Adjustment system (2) with external enables
The appliance may also be controlled via generic enable devic-
es (e.g. thermostats, timers, buttons, contactors...) fitted with
voltage-free NO contacts. This system only provides elementary
control (on/off, with fixed setpoint temperature), without the
important functions of system (1). Control of the cascade be-
tween GAHP/GA and AY00-120 is left to the user.
For connection of the selected device to the appliance's
electronic board please refer to Paragraph 4.4
