1. INTRODUCTION
1.1 DESCRIPTION
The FCAx3 is an electronic refrigeration controller designed to be a direct replacement for electro-mechanical thermostats
to provide precise and efficient refrigeration control for up to 3 outputs using up to 3 inputs (temperature sensor and/or door
switch). The FCAx3 provides advanced defrost modes as well as energy saving during periods of low demand using a door
switch.
The FCAx3 is built to last meeting industry benchmarks and offering complete voltage protection including high/low voltage
to all connected outputs. To also help protect and extend the operating life of the connected outputs the FCAx3 provides zero
voltage crossing.
The FCAx3 has internal Bluetooth (optional) or can be connected to an external Bluetooth module (GBR) allowing remote
access via the Smart Device App to authorized service personnel to access controller data logs and control parameters. BLE also
transmits Eddystone and iBeacon for proximity marketing (nearby customer engagement).
The FCAx3 can be connected to a connectivity device to provide always-on connectivity to send telemetry and performance
data to the portal, and Wi-Fi asset location or a digital display to provide live temperature reading, parameter and mode
configuration and alarms/errors.

1.2 MODEL VARIANTS
The “x” in the part number FCAx3 indicates the number of controllable outputs. There are three models available:
FCA13 = 1 relay, 16 Amp (Compressor)
FCA23 = 2 relays, 16 Amp (Compressor) + 5 Amp (Aux1)
FCA33 = 3 relays, 16 Amp (Compressor) + 2x 5 Amp (Aux1 & Aux2)
