A
Mounting Slots
- The SST-W100 comes with wall anchors and screws to mount to an existing wall. Place the back
panel on the wall and mark where the wall anchors are to be installed.
B
Terminal Blocks
- All wiring is connected to one of the two terminal blocks. Refer to table below for a brief
description of each position.
C
Wire Slot
- This rectangular slot is where the wires coming from the HVAC system and/or remote sensors are fed
into the thermostat.
Terminal Block - Left
24RC
Connect the 24V AC hot wire from the
transformer on HVAC system to the
24RC terminal. When there is a separate
heating and cooling system, the wire
from the transformer on the cooling
system is wired here. **See Note below.
G
Connect to the fan terminal on the
HVAC system.
Y1
Connect to the 1st stage cooling
terminal on the HVAC system.
Alternately, connect to the 1st stage
compressor in a heat pump system
Y2
Connect to the 2nd stage cooling
terminal on the HVAC system.
Alternately, connect to the 2nd stage
compressor in a heat pump system
RS2
Connect to remote temperature sensor
RS2
. No polarity is observed.
RS2
Connect to remote temperature sensor
RS2
. No polarity is observed.
RSC
If there is a shield on the cable that
connects to remote sensor
RS2
,
connect that shield to the
RSC
terminal.
A1
• Auxiliary relay 1 can switch external
equipment such as a humidifier,
dehumidifier, and external vent
damper on and o
ff
.
• Auxiliary relay 1 can be turned on and
o
ff
according to workflows and
triggers set up in RacePoint Blueprint.
• Can control the speed of an external
dehumidification fan when an air
handler is used for dehumidification.
Terminal Block - Right
24C
Connect the common wire from the transformer
on HVAC system to the
24C
terminal. When
there is a separate heating and cooling system
transformer, the common wire from the cooling
and heating system is wired here.
24RH
When there is a separate heating and cooling
system, the wire from the transformer on the
heating system is wired here. **See Note below.
W1
Connect to 1st stage heating terminal on the
HVAC system.
W2/0
Connect to 2nd stage heating terminal on the
HVAC system. If the system is a heat pump type
system, connect to the changeover terminal (O).
RS1
Connect to remote temperature sensor
RS1
. No
polarity is observed.
RS1
Connect to remote temperature sensor
RS1
. No
polarity is observed.
RSC
If there is a shield on the cable that connects to
remote sensor
RS1
, connect that shield to the
RSC
terminal.
A2
• Auxiliary relay 2 can switch external
equipment such as a humidifier, dehumidifier
and external vent damper on and o
ff
.
• Auxiliary Relay 2 can be turned on and o
ff
according to workflows and triggers set up in
RacePoint Blueprint.
**Note:
When connecting power to the thermostat, if there are separate transformers for cooling and heating, the
transformer from the cooling system is wired to the
24RC
terminal and the transformer from the heating system is wired
to
24RH
terminal. In this scenario, jumper
JP1
located on the PCB circuit board must be cut to separate the
24RH
and
24RC
terminals. Failure to cut this jumper could result is damage to the circuit board when powering the system. Refer to
