(08B): Valve / Element Type; (09B): Fan Type - Lutron Electronics PALLADIOM Configuration Manual

Step 4: Set the SMC55-HWQS Basic Parameters for System
Compatibility

(08b): Valve / Element Type

Applicable Systems: Fan Coil Units and Radiant Underfloor heating.
Use this parameter to select the type of valve control for heating and cooling. The heating and cooling valves can either have a
relay control (two position On / Off) or a proportional control (0–10 V-). This parameter will be skipped in the menu if you select
any option other than '02: 2-pipe FCU', '03: 4-pipe FCU' or '04: Radiant Underfloor Heating' for the previous parameter (01b).
Refer to your HVAC equipment manual to identify the type of valve control supported by your HVAC equipment. The different
options available for this parameter are listed in the table below:
Table 11: Values for Type of Valve Control
Valve / Element Type (08b)
00: Relay
01: 0–10 V-
02: Floating point (FCUs only)

(09b): Fan Type

Applicable System: Fan Coil Units.
Use this parameter to select the type of control for fan. The fan can have either a relay control (3-speed fan control) or a
proportional control (0–10 V-).
Note: Some of the Fan Coil Units can have a two-pole contact closure with a 2-speed fan (medium and high) or a single speed
fan (low). Refer to the wiring diagram in thermostat installation guide to install the SMC55-HWQS with Fan Coil Units with a
2-speed or single-speed fan.
This parameter will be skipped in the menu if you select any option other than '02: 2-pipe FCU' or '03: 4-pipe FCU' for the
previous parameter (01b). Refer to HVAC equipment manual to identify the type of fan control supported by your HVAC
equipment. The different options available for this parameter are listed in the table below:
Table 12: Values for Type of Fan Control
Fan Type (09b)
00: Relay 3-speed fan
01: 0–10 V- continuous speed
For floating point control, see Application Note #630. Basic Configuration set for the valve type is overridden when selecting Floating Point.
