Indicates if 1 or 2 HVAC equipment types are used and what equipment is connected.
2.
HVAC controller selection mode:
Indicates what type of HVAC controller is being used and sets the address for it (if needed).
3.
Basic configuration mode:
Configures the HVAC controller according to the type of HVAC system.
Note:
Depending on the options selected, certain programming modes may be skipped. It may be necessary to enter certain
programming modes twice if there are two equipment types. The thermostat will only display menus that are relevant to the

WARNING
Shock Hazard.
Improper configuration can cause property damage, personal injury, or death. Installation and
service must be performed by a licensed professional HVAC installer (or the equivalent) or service agency.
1.
Enter equipment configuration mode.
When a thermostat receives power, it will automatically enter equipment configuration
mode if equipment configuration has not been previously completed.
If no HVAC controller is going to be connected directly to the thermostat, skip this section. This is known as a companion thermostat
and configuration will be completed by a certified Lutron dealer via the HomeWorks QS designer software.
2.
Select value for equipment configuration: Select the configuration option which describes the HVAC equipment
connected to the thermostat.
Using the table below, press or to select the correct equipment configuration being used
and press and hold
to save the configuration. The thermostat will then enter HVAC controller selection mode for the first zone.

Description
System Example
01
1
There is a single piece of equipment attached
to the HVAC controller communication link.
The thermostat is connected to an SMC55-HWQS which handles both
heating and cooling of the HVAC zone.
02
2 – both heating
and cooling
equipment
connected to the
thermostat
The thermostat controls two different HVAC
equipment types. Both pieces of HVAC
equipment are connected to the HVAC
controller communication link.
The thermostat is connected to an SMC55-HWQS used for underfloor
heating of the HVAC zone. There is also a Cool Automation CoolPlug
interface connected to the same thermostat used to cool the space. Both
pieces of equipment are in the same HVAC zone and the thermostat can
be used to heat or cool the zone.
03
2 – only heating
equipment
connected to the
thermostat
The thermostat controls two different HVAC
equipment types. Only heating equipment is
physically connected to the HVAC controller
communication link.
The thermostat is connected to an SMC55-HWQS used for underfloor
heating of the HVAC zone. There is also 3rd party HVAC equipment
connected to the HomeWorks QS processor via integration, which is used
to cool the same zone. The thermostat can be used to heat or cool the
zone.
04
2 – only cooling
equipment
connected to the
thermostat
The thermostat controls two different HVAC
equipment types. Only cooling equipment is
physically connected to the HVAC controller
communication link.
The thermostat is connected to a Cool Automation CoolPlug interface to
handle cooling the HVAC zone. There is also 3
rd
party HVAC equipment
connected to the HomeWorks QS processor via integration, which is used to
heat the same zone. The thermostat can be used to heat or cool the zone.
