LUTRON 653 Right Thermostat Control Datasheet
Application Note #653
New Construction or Retrofit Application
Most Lutron thermostat control solutions can be easily installed in a new construction or retrofit application. If the Lutron
thermostat control is to be installed in a retrofit application, there are no pre-install considerations since everything is typically
installed already. If this is the case, skip to Find the Existing Thermostats and Check the Connections Used. Continue
with this section if the application is either new construction or if the HVAC equipment is being replaced.
New construction is convenient because the walls are open and easily accessible. Ensure that the proper wire size and
number of conductors are run from the HVAC equipment to the thermostat locations. Lutron thermostats use 18 AWG to
22 AWG (1.0 mm2 to 0.5 mm2) solid wire. In an application where a heat pump will be used or there is a strong possibility of
one being used, make sure that 7 conductors are installed. In all other cases, make sure five conductors are installed. Run
all wires to the location where the thermostat will be mounted. Verify that the technician completing the wiring follows the
specifications mentioned above.
The HomeWorks Palladiom HVAC controller (e.g., SMC55-RESI, SMC55-HWQS, SMC55-RESI-2) is typically mounted with
the HVAC equipment so the wire runs between those devices and the HVAC equipment are usually short.
The Lutron wireless thermostat (L-HWLV2-WIFI) has an integrated temperature sensor. Like a typical thermostat, they are often
wired in the living space and require longer wire runs. Remote mounting options are available via remote temperature sensors.
Having the correct number of conductors will ensure that there is enough wire to use either of the 24 V~ Lutron control options.
SMC55-RESI/SMC55-HWQS/SMC55-RESI-2, and L-HWLV2-WIFI all require a common wire connection.
This document will help to compare and contrast all of Lutron control solutions in order to help identify the right choice for
every application.
