WARNING: Shock / Fire Hazard.
Improper configuration or installation can
cause property damage, personal injury, or death. Installation and service
must be performed by a licensed professional HVAC installer (or equivalent) or
service agency.
Note:
Configuration is required when a new thermostat is added.
HVAC Controller Selection Mode
(only available with thermostat version 1.10 or later)
1. Enter HVAC controller selection mode.
When a thermostat receives power, it will
automatically enter HVAC controller selection mode if an HVAC controller has not
been previously selected.
If no HVAC controller is going to be connected directly to the thermostat, skip this
section. This configuration will be completed by a certified Lutron dealer via the
HomeWorks QS Designer software.
2. Select value for parameter ID "01": Select the HVAC controller connected to
the thermostat.
Using the table below, press
Set
or
Set
to select the correct HVAC
controller being used and press

If SMC55-RESI was selected, proceed to the next section.
Otherwise, skip the next section.
Note:
"E1" will show on the display if the thermostat is not able to communicate with
the HVAC controller.
Note:
If a new HVAC controller type or address is used, the HVAC controller
selection mode will need to be reentered. See
Reenter Configuration
section.
Configuring the SMC55-RESI
1. Enter basic configuration mode.
If the SMC55-RESI was the HVAC controller
selected in HVAC controller selection mode and it was not previously configured,
basic configuration mode will automatically be entered.

Troubleshooting
Symptom
Possible Cause
Solution
Display is blank
The thermostat does not have power.
Check the wiring to confirm that Common (Black) and V+ (Red) are connected to
a 24–36 V
-
power supply.
E0 shown on the master thermostat
The thermostat temperature sensor is not functioning properly.
Contact Customer Assistance.
E0 shown on the companion
thermostat
A companion thermostat will show E0 if the temperature sensor for that
zone is missing.
Check the error code on the master thermostat.
E1 shown on the master thermostat
Wiring issue between the thermostat and the HVAC controller or HVAC
controller does not have power.
Ensure that the HVAC controller communication link is wired correctly and
isolated from all other connections and that the HVAC controller has power.
The incorrect HVAC controller or modbus address was selected.
Enter HVAC controller selection mode and select the correct HVAC controller
and modbus address.
E1 shown on the companion
thermostat
Wiring issue between the processor and HVAC controller (if HVAC
controller is connected to the processor).
Check the wiring between the processor and HVAC controller.
The master thermostat (connected to the HVAC controller) is
disconnected from the processor.
Ensure that the QS link between the master thermostat and the processor is
wired correctly.
E2 shown on the display
Remote temperature sensor is malfunctioning or misconfigured.
Check the wiring between the sensor and the HVAC controller and confirm
configuration.
E3 shown on the display
Changeover sensor malfunctioning or misconfigured (applicable only for
2-pipe systems).
Check the wiring between the sensor and the HVAC controller and confirm
configuration.
E4 shown on the display
QS link wiring issue.
Contact Customer Assistance.
E5 shown on the display
Incorrect HVAC controller or thermostat model.
Ensure that SMC55-RESI and HQWT-T-HW are being used.
E6 shown on the display
Slab temperature sensor for underfloor heating is missing, malfunctioning
or misconfigured.
Check the wiring between the slab sensor and the HVAC controller and confirm
configuration.
System is not heating / cooling
The HVAC controller or HVAC equipment may not have power.
Ensure that the HVAC controller and HVAC equipment have power and are
correctly wired. Consult an HVAC professional if the issue persists.
System is not heating / cooling as
expected
Mounting location of the thermostat or remote temperature sensor is
incorrect.
Refer to
Mounting
section.
Wiring issue between the HVAC controller and the HVAC system.
Check the wiring.
The HVAC system may not have power.
Ensure that the HVAC system has power.
