Overview
The Sollatek FCA 23 holds an average product temperatures of 32-40°F (0-4.4°C) for universal applications and 39-71°F (3.9-21.7°C) for wine/ chocolate applications. The electronic temperature control requires a neutral line to complete the circuit.
NOTE: Always install the provided relay. Some applications may have an existing relay; in these cases replace the existing relay.
WARNING! Electrical shock or burn hazard. Powering off an electronic control does not remove power from all components. Unplug the unit or turn off the power supply before proceeding.
WARNING! Sharp edges. Take care when installing, cleaning, servicing, and maintaining the equipment.

Control Operation
The electronic temperature control… · Cycles the compressor on and off based on the return air temperature. See table 2 and table 3. · Automatically defrosts every four (4) hours of compressor run time. · Initiates an additional defrost if the evaporator coil temperature drops to 9°F (12.8°C). · Defrosts between 4 min minimum and 40 min maximum, or until the evaporator coil measures 38°F (3.4°C).

Before You Begin (Mechanical Controls)
If converting a mechanical control to an electronic control, see the following information. If replacing an electronic control, procede to “Temperature Control Installation” (pg. 6).
Determine Airflow Direction
Determine the airflow direction through the evaporator coil. See figs. 1 and 2. Airflow direction dictates probe placement. the black (thermostat) probe will be placed in the return air stream.
Probe Side

Determine Voltage Wire & Label Wires
1. At the temperature control, with a volt meter, locate the following wires and mark them as directed below:
· Line in/Line; Label wire LINE. · Line out/Load; Label wire LOAD. 2. Remove the mechanical control.
4-Wire Fan Motors
TRUE T-Series or GDM ONLY Check the unit for a 4-wire evaporator fan motor or a sticker (see fig. 3) on the evaporator housing. If present, rewire the fan motor before proceeding. See “Rewiring the 4-Wire EBM Fan Motor” (pg. 15).
Fig. 3. Fan motor sticker will be on the evaporator housing.

Troubleshooting
Basic Troubleshooting
In addition to reading the control indicator light codes [see “Control Indicator Light Codes Table” (pg. 13)], note the potential solutions below: · Check the terminal connections:
· If the power wires (Live In and Comp) are reversed, the control indicator lights will not light and the compressor will not start. See fig. 1. for light locations.
· If the probe wires are reversed, the control will not cycle correctly. · Check if the black probe is touching metal. If so, the probe is reading surface temperature
instead of return air temperature.

Rewiring the 4-Wire EBM Fan Motor
If the evaporator fan motor cycles or is a 4-wire motor, it must be rewired to operate correctly with the new electronic temperature control. See the procedure below. 1. Locate the black EBM wire sleeve containing black, brown, blue,
and green/yellow wires. See fig. 1.
2. Cut the black and brown fan motor wires 1″ (25.4 mm) from their respective connectors. See fig. 2.
3. With a provided 2-way lever connector, cap the black wire left attached to the original connector.
4. With a provided 2-way lever connector, cap the brown wire left attached to the original connector.
5. Strip 7/16″ (11.1 mm) of insulation from the fan motor side of the black and brown wires.
6. With a provided 3-way lever connector, connect the stripped black and brown fan motor wires to the provided bare black wire.
7. Crimp a provided spade connector to the bare black wire.
8. Connect the black wire to the temperature control Aux1 terminal. See fig. 3.
