Free Energy Band™ TH193 HC  
Heating/Cooling Room Thermostat  
Installation  
Overview  
Product Description  
The TH193 HC thermostats are proportional dual  
output, dual setpoint, two-pipe (dual one-pipe, low  
air capacity) or three-pipe (dual two-pipe, high air  
capacity) temperature controllers. Each TH193 HC  
chassis includes a wall plate for thermostat  
installation using a variety of rough-in installation  
kits.  
The TH193 HC thermostat and wall plate mount  
vertically to a wall using a variety of rough-in  
installation kits (for example, wall box kits or tubing  
terminal kits). The ends of the air lines from the  
rough-in installation kits have terminal adapters that  
snap into the wall plate. Terminal adapters are also  
available separately as orderable accessories. See  
TB 237 (155-244P25).  
Prerequisites  
NOTE: Certain retrofit applications allow air  
connections directly to the thermostat  
chassis.

Review all instructions before beginning  
installation.  
Verify job drawings are available to reference  
specific job site information as needed.  
The S, R1, and R2 labels on both the thermostat  
chassis and the wall plate identify the air line  
connections. The thermostat plugs into the terminal  
adapters on the wall plate. See Piping for typical  
connections.  
Verify rough-in installation kits (wall-box or  
tubing runs) are pre-installed.  
Two cover screws plus latch arms on the wall plate  
hold the thermostat in place. The cover fits over the  
thermostat and the two cover screws fasten it to the  
wall plate.

Siemens TH193 HC Manual: Questions and Answers

How do I install Siemens TH193 HC on my wall?

Mount the wall plate first, then insert the thermostat ports into the terminal adapters, attach the cover, and secure it with screws.

  1. Remove terminal adapters from the air link and snap them into the wall plate at their respective locations.
  2. Guide the mounting screws through the slotted keyholes on the wall plate and partially insert them into the wall.
  3. Orient the wall plate so it is square and level, then tighten the mounting screws.
  4. Moisten the thermostat supply and return ports, then carefully insert them into the terminal adapter O-rings on the wall plate.
  5. Mount the cover over the thermostat and use a 1/16-inch Allen wrench to tighten the two cover screws. Instruction Manual, p. 1

Can I connect tubing directly to Siemens TH193 HC chassis without terminal adapters?

Yes. Terminal adapters are only required to retain the plug-in feature. Otherwise, 5/32-inch tubing can connect directly to the thermostat chassis using compression rings P/N 141-388. Instruction Manual, p. 2
