About your thermostat

The TH115 programmable thermostat has three temperature control modes

• A mode:
  • controls the ambient air temperature
• F mode:
  • controls the floor temperature using an external temperature sensor
• AF mode:
  • controls the ambient air temperature
  • maintains the floor temperature within desired limits using an external temperature sensor

Supplied Parts

• One (1) thermostat
• Two (2) mounting screws
• Four (4) solderless connectors for copper wires
• One (1) floor sensor
• One (1) flat-tip screwdriver

Controls

• Place at Off to cut power to the heater (e.g., in the summer). This will not affect the time and temperature settings.
• When the backlight button or either of the  buttons is pressed, the display illuminates for 12 seconds.

Display

• The thermostat normally displays the actual (measured) temperature. To view the setpoint temperature, briefly press either of the buttons. The setpoint will appear for 5 seconds. To change the setpoint temperature, press one of the buttons until the desired temperature is displayed. To scroll faster, press and hold the button.

Installing the thermostat

1. Turn the heating system off at the main electrical panel.
2. Loosen the bottom screw and remove the thermostat faceplate from its wallplate. (The screw cannot be completely removed.)
3. Connect the thermostat to the load and to the power supply.
4. Connect the floor sensor.
5. If you wish to connect a remote control device.
6. Install the wallplate to the electrical box using the provided screws.
7. Set the configuration switches on the back of the faceplate.
8. Install the faceplate back on the wall plate and tighten the screw.
9. Apply power to the heating system.
10. Test the ground fault protection.

Wiring diagram

NOTE:  Connect the wires using the provided solderless connectors for copper wires.

Connecting the floor sensor / remote control

1. Insert the floor sensor cable through one of the two openings on the wallplate and connect the sensor wires to terminals 1 and 2 (no polarity).
   • The sensor cable must not come in contact with the electrical wires and must be routed outside the electrical box and follow the wall down to the floor.
   • Position the sensor cable such that it does not come in contact with the floor heating wires. The sensor must be centered between two-floor heating wires for best temperature control.
   • Do NOT staple the sensor head (the plastic end) to the floor. Doing so might damage the sensor. Any damage might not be noticeable during testing but can become apparent several days later.
2. If you wish to connect a remote control device, insert the wires (use 18- to 22-gauge flexible wires) through one of the two openings on the wallplate and connect them to terminals 2 and 3 (no polarity).

Set the configuration switches

Configuration switches are on the back of the faceplate.

1. Early Start is used in Automatic mode only. When Early Start is enabled (on), the thermostat determines when to start heating so the Comfort temperature is attained at the beginning of periods 1 and 3. When Early Start is disabled (off), heating starts only at the beginning of periods 1 and 3; thus there is a delay before the Comfort temperature is reached.
2. To select the F Mode, place the switch in the F position. To select the AF Mode, place the switch in the AF position and ensure that the temperature sensor is connected to the thermostat. To select the A Mode, place the switch in the AF position and ensure that the remote temperature sensor is NOT connected to the thermostat.

place the thermostat in Vacation mode:

1. Press  the button on the thermostat. When the Vacation mode is activated this way, the icon appears on the screen without flashing.
2. From any remote control device equipped with a dry contact. When the contact closes, the thermostat is placed in Vacation mode and the  icon flashes on the screen. All buttons on the thermostat are locked. When the contact opens, the thermostat returns to the previous mode.
   NOTE:  When the Vacation mode is activated from a remote control device, it can only be deactivated using the device.

Ground fault protection (GFCI)

This ground fault protection thermostat is different from conventional thermostats. In the event of a ground fault, the ground fault protection mechanism on the thermostat will trip and quickly stop the flow of electricity to prevent serious injury.
Definition of a ground fault
Instead of following its normal safe path, electricity passes through a person’s body to reach the ground. For example, a defective floor heating mat can cause a ground fault. A ground fault protection thermostat does not protect against circuit overloads, short circuits, or electrical shocks. For example, you can still receive an electrical shock if you touch bare wires while standing on a non-conducting surface such as a wood floor.
Ground fault protection reset
When the ground fault protection mechanism trips, the TEST light is On (red). To reset the ground fault protection, switch the thermostat to Off and back to On. The TEST light will turn off.

Testing the ground fault protection
To ensure the ground fault protection is always in working order, test it once the thermostat is installed and on a monthly basis thereafter.

• Increase the setpoint temperature above the measured temperature in order to activate the heating system.

• Press the TEST button.

  • If the TEST light does NOT turn on, the test has failed. Cut power to the heating system at the main electrical panel, have an electrician verify the installation and, if necessary, replace the thermostat.
  • If the TEST light turns on, continue the test.

• Switch the thermostat to Off then back to On.

  • If the TEST light turns off, the test has passed. Set the thermostat back to the desired temperature.
    The test is now completed.

  • If the TEST light remains on, the test has failed. Continue with the rest of the procedure.

• Switch the circuit breaker (at the service panel) of the heating system to off then back to on.

• Repeat the test. If the test fails again, cut power to the heating system at the main electrical panel, have an electrician verify the installation and, if necessary, replace the thermostat.

Error Messages

• LO: The measured temperature is below the display range. The heating is activated.
• HI: The measured temperature is above the display range. The heating is deactivated.
• ERl: Verify the thermostat connection and sensor connection.
