3. Moisten the thermostat supply and return ports
to lubricate them. Carefully insert the thermostat
ports into the terminal adapter O-rings on the
wall plate.
4. Mount the cover over the thermostat.
NOTE: For applications that use the 1/2-inch
setpoint adjustment knob, align the
keyhole in the cover over the shaft
protruding from the thermostat when
mounting the cover.
Use the hex key end of the calibration and cover
screw wrench or a 1/16-inch Allen wrench to
tighten the two screws that secure the cover in
place.
5. Place the optional 1/2-inch setpoint adjustment
knob on the shaft protruding through the cover.
Use the hex key end of the calibration and cover
screw wrench or a 1/16-inch Allen wrench to
tighten the set screw on the knob.
The installation is complete.

Remodeling Installation Reference
When converting from Model TH180 or TH182 to the
TH19X, you need:
• TH193 HC Chassis.
• A new cover. The TH180 or TH182 cover
does not fit the TH19X chassis or vice versa.
• Terminal adapters. These adapters are
required to retain the plug-in feature only.
Otherwise, 5/32-inch (4 mm) tubing can
connect directly to the thermostat chassis.
Use compression rings (P/N 141-388) to
secure connections.
When converting from competitor models to the
TH19X, you need:
• TH193 HC FEB Chassis.
• New cover.
• Adapter Kit (see TB 214, TH192 Adapter Kits
Technical Bulletin, 155-231P25).
Piping
NOTE: All piping (Figures 2 and 3) must conform to
local codes and regulations and must
comply with the local authority having
jurisdiction.

Connections.

Connections.
Thermometer Calibration
1. Use a test thermometer to read the current room
temperature.
2. Place a screwdriver in the center of the
thermometer assembly (Figure 4). Carefully
rotate the thermometer assembly until the
pointer tip indicates the correct room
temperature.
NOTE: Avoid breathing on or touching the
bimetal spiral since this affects the
temperature reading.
