Step 3: Wire the HVAC signals and power supply
Using the diagram on the previous page and the appropriate wiring diagram below, connect the power
supply and fan coil unit to the FCU controller. Wire harnesses can be extended using 18 AWG or
22 AWG (1.0 mm or 0.5 mm ) wire. Use twisted pair, shielded cables to extend analog I / O and FCU
2 2
controller links. All terminal blocks are removable. For color diagrams, see the myRoom Fan Coil Unit
Controller specification submittal (P/N 3691082) on www.lutron.com.

Important Notes

• Each inductive load, driven by the relay contacts, must include a suppression device such as a
peak limiter or RC circuit to extend relay life.
• Do not connect relay outputs to capacitive loads.
• Improperly sized or otherwise incorrect circuit‐breakers or fuses may allow excessive current
beyond the capacity of the controller.

Step 4: Basic Configuration Instructions
The FCU controller must be correctly configured for the fan coil unit. The Palladiom thermostat is
used to configure the FCU controller. The thermostat must be connected to the FCU controller and
both must be powered to set a configuration.
1. Determine the basic configuration number of the system using the table below.

2. Enter basic configuration mode.
a. If the thermostat has been powered for over 15 minutes, cycle power to the thermostat. See the
Palladiom Configuration Instructions (P/N 041563) at www.lutron.com. The previously saved
configuration is restored after a power cycle.
b. Hold the C F and
buttons and hold only the
c. The thermostat will enter basic configuration mode, with "Set" and one circle filled in on the
display.
Hold 3 seconds to save and exit
configuration mode.
3. Set basic configuration mode.
a. Once in basic configuration mode, Tap the } or { buttons to display the desired
configuration number found in the table above. Only the supported options are displayed.
b. Hold the u button for 3 seconds to save this configuration. The display will flash, then normal
operation will begin.
4. Advanced configuration mode.
a. To modify optional advanced configuration parameters, see the Palladiom Configuration
Instructions (P/N 041563) at www.lutron.com
