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.  

Expected Installation Time  

30 Minutes  

Required Tools  

Procedure  

•

•

•

•

Medium flat-blade screwdriver  

Needle nose pliers  

Small level  

The following procedure is for a typical thermostat  

installation and assumes the rough-in installation kit  

is in place. See Figure 1.  

1. The rough-in installation kit provides a supply  

(blue) air line and a return air line joined by an  

air link. Remove the terminal adapters from the  

air link and snap them into the wall plate at their  

respective locations.  

Calibration and cover screw wrench or 1/16-  

inch Allen wrench (P/N 192-632)  

•

Needle Probe with 1-1/2 inch diameter, 0 to  

30 psig (0 to 200 kPa) test gauge  

(P/N 192-633)  

2. Using the mounting screws supplied with the  

thermostat chassis, install the wall plate on the  

wall as follows:  

Warning/Caution Notations  

Personal injury or loss of life  

may occur if a procedure is not  

performed as specified.  

WARNING  

a. Guide the screws through the slotted  

keyholes on the wall plate and partially insert  

them into wall.  

Equipment damage or loss of  

data may occur if the user  

does not follow a procedure as  

specified.  

CAUTION  

b. Orient the wall plate so that it is square and  

level.  

c. Tighten the mounting screws to secure the  

wall plate in place.

SIEMENS TH193 HC Heating-Cooling Room Thermostat Instruction Manual Overview

Summary of Contents

• Page 1: Installation instructions for the TH193 HC heating/cooling room thermostat are provided. The TH193 HC thermostats are dual output, dual setpoint temperature controllers for various piping systems. Each thermostat includes a wall plate for installation with different rough-in kits. The thermostat and wall plate mount vertically to a wall using various installation kits. Certain retrofit applications allow air connections directly to the thermostat chassis. Verify job drawings are available for specific site information before installation. Two cover screws and latch arms secure the thermostat to the wall plate. Expected installation time is approximately 30 minutes. Required tools include a medium flat-blade screwdriver, needle nose pliers, and a small level. Warnings indicate potential personal injury or equipment damage if procedures are not followed.
• Page 2: Installation instructions provide guidance on setting up the thermostat. Moisten the thermostat supply and return ports to lubricate them before installation. Terminal adapters are required to retain the plug-in feature; otherwise, tubing can connect directly to the thermostat chassis. Mount the cover over the thermostat, ensuring proper alignment with the adjustment knob. When converting from competitor models to the TH19X, specific components are needed, including the TH193 HC FEB chassis and a new cover. All piping must conform to local codes and regulations. Use a test thermometer to read the current room temperature for calibration. Carefully rotate the thermometer assembly to indicate the correct room temperature. When converting from Model TH180 or TH182 to the TH19X, a new cover is necessary as the old one does not fit. Avoid breathing on or touching the bimetal spiral during calibration to ensure accurate temperature readings.
• Page 3: Installation instructions provide procedures for recalibrating the thermostat. The output pressure test port is accessible without removing the thermostat cover. For one-pipe thermostats, the test port is on the right side; for two-pipe thermostats, it is on the left side. Thermostat limit stops define the minimum and maximum thermostat setpoints. To change the limit stop settings, use needle nose pliers to pull the limit stop between the setpoint cam gear teeth. Changing the limit stop position one gear tooth changes the limit stop setting by 1-1/3°F (0.7°C). If the wrong test port is used, thermostat damage can occur. The factory thermostat sensitivity setting is approximately 2.5 psi/°F (31 kPa/°C). If the thermostat sensitivity is adjusted, recalibrate the thermostat. The thermostat is factory-calibrated to a control pressure of 7.5 psi (52 kPa) at a setpoint and ambient temperature of 72°F (22°C).
• Page 4: Installation instructions provide essential guidance for troubleshooting and calibration of heating systems. Verify that the room temperature is between 70°F and 80°F (21°C and 27°C) before calibration. Check the supply pressure, which should be 25 psi (172 kPa). Allow the thermostat to adjust to the new setting after making changes. Use a test gauge and needle adapter to measure control pressure at the heating test port. Ensure clean dry supply air at 18 psi (124 kPa) minimum before troubleshooting. The test port location differs for one-pipe and two-pipe thermostats. Using the wrong test port can damage the thermostat. The company reserves the right to change specifications and models as improvements are made. Feedback on the document is encouraged for continuous improvement.
