2.1 BRC1C71 Wired Remote Controller
The optional Remote Controller for indoor units provides versatile system control.
Remote controller wiring for a simplified BRC2A71 Remote Controller is the same as that of the standard BRC1C72
Remote Controller. Because the functions of the simplified remote controller are limited, we recommend using in
combination with a central remote controller.
2.1.1 Appearance and Functions
2.1.2 Example of Control by Remote Controller
Large liquid crystal screen displays complete operating status.
Digital display allows temperature settings in 1°F units.
Operation start/stop can be programmed using timer for periods up to 72
hours.
Thermostat sensor provides room temperature control for optimum
comfort.
Microcomputer monitors room temperature and preset temperature,
automatically selecting cool/heat operation. (VRV System Heat Recovery
Series only)
Use any indoor remote controller to select cool, heat, or fan mode without
using the main cool/heat selection switch.
Continuous monitoring of 40 possible malfunctions with self-diagnosing
capability for messaging you immediately in the event of a problem.
Allows a variety of field settings from remote controller.

Control Devices EDUS39-605

2.1.3 Two Remote Controllers
1 indoor unit is controlled by 2 remote controllers from 2 separate locations
This is a convenient system for operating an office indoor unit from the reception area, or an indoor unit from a local or
remote location.
Operation mode of the indoor unit is last command priority.
Remove the front panel of the remote controller and set the main/sub changeover switch on the PC board to MAIN
for the main remote controller, and to sub SUB for the sub remote controller.
Note:
The remote controller is equipped with a thermostat sensor. If the main and sub remote controllers are mounted in
separate rooms, set the main remote controller so that its thermostat sensor is not used so that it does not determine
the temperature for all rooms.
2.1.4 Group Control
Simultaneous control of up to 16 units with a single remote controller:
The following diagram illustrates a convenient system for simultaneous control of several indoor units on a wide, single
floor.
Wiring for remote controller group control has no polarity, therefore P1and P2can be switched.
All indoor units within the group have the same setting, and each indoor unit is controlled individually by its own built-
in thermostat.
Because automatic address is used, an address does not have to be set by remote controller for group control.
Note:
Only remote controller wiring is shown.
