CAUTION:

Installation must be carried out by a certified electrician and must comply with national and local electrical codes.
To prevent severe shock or electrocution, always cut the power at the service panel before working with wiring.
Use this thermostat for resistive loads only.
Do NOT install the thermostat in an area where it can be exposed to water or rain.
Avoid locations where there are air drafts (top of the staircase, air outlet), dead air spots (behind a door), direct sunlight or concealed chimney or stove pipes (except for floor heating systems).
For a new installation, choose a location about 1.5 m (5 ft.) above the floor.
Install the thermostat on an inside wall facing the heating system (except for floor heating systems).
Install the thermostat onto an electrical box.
Use special CO/ALR solderless connectors if you connect the thermostat to aluminum wires.
Keep the thermostat’s top and bottom air vents (openings) clean and unobstructed at all times..

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

See page 9 on how to change the temperature control mode setting.
Supplied Parts

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

* Select models only; required for floor heating applications only.

Controls

*Place at Off/Standby 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

Turn the heating system off at the main electrical panel.
Loosen the bottom screw and remove the thermostat faceplate from its wallplate. (The screw cannot be completely removed.)
Connect the thermostat to the load and to the power supply (see page 7).
If the thermostat will be used in F or AF Mode (see page 9), connect the floor sensor (see page 8).
WARNING: For floor heating applications, you must install a separate ground protection device at the main electrical panel or use a thermostat with a built-in ground protection device.
If you wish to connect a remote control device, see page 8.
Install the wall plate to the electrical box using the provided screws.
Set the configuration switches on the back of the faceplate (see page 9).
Install the faceplate back on the wall plate and tighten the screw.
Apply power to the heating system at the main electrical panel.

Wiring diagram

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

Insert the floor sensor cable through one of the two openings on the wall plate and connect the sensor wires to terminals 3 and 4 (no polarity).
• The sensor wires 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 the 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.
If you wish to connect a remote control device (see page 17), insert the wires (use 18- to 22-gauge flexible wires) through one of the two openings on the wallplate and connect them to terminals 1 and 2 (no polarity).

Connecting the floor sensor / remote control

#	Configurations	Up	Down
1	Display format	°F / 12 h	°C / 24 h
2	Early Start¹	Enable	Disable
3	Temperature control mode²	F A	AF

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.
See page 3. 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.

Time and day

To set the clock and the day:

Press the Hour button to set the hour.
Press the Min button to set the minutes.
Press the Day button to set the day.
Press the Mode/Ret button to return the thermostat to a normal display.

NOTE: The thermostat will automatically return to normal display if no button is pressed for 60 seconds.

Daylight Saving Time

When the Daylight Saving Time function is enabled (On), the thermostat automatically switches to Daylight Saving Time on the second Sunday of March and to normal time on the first Sunday of November.
NOTE: The Daylight Saving Time function is disabled (default setting) when the clock loses its setting.
To set the Daylight Saving Time function and to set the date:

Press the Day button (3 seconds) until DLS appears on the screen.
Press either of the buttons to toggle between On (enabled) and Off (disabled).
Press the Day button briefly. The year setting is displayed.
Press either of the buttons to set the current year.
Press the Day button briefly. The month setting is displayed.
Press either of the buttons to set the current month.
Press the Day button briefly. The date setting is displayed.
Press either of the buttons to set the current date.
Press the Mode/Ret button to return the thermostat to a normal display.

NOTE: The thermostat will automatically return to normal display if no button is pressed for 60 seconds.

Floor temperature limits (AF mode only)

WARNING: To avoid damaging your floor, follow your floor supplier’s recommendations regarding floor temperature limits.
The minimum and maximum floor temperature limits are 5.0°C (41°F) and 28.0°C (82°F) by default. To modify these limits, proceed as follows:

Switch the thermostat Off.
Press and hold the button.
Switch the thermostat back to On.
Release the button when the minimum temperature limit (FL: LO) appears.
Set the minimum temperature limit using the buttons.
Press the button to display the maximum temperature limit (FL: HI).
Set the maximum temperature limit using the buttons.
Press Mode/Ret to return the thermostat to the normal display.

The thermostat has 3 preset temperatures. Their default settings are shown in the following table.

Preset temperature	Intended use	Icon	A/AF modes	F mode
Comfort	When at home		21.0°C (70°F)	28.0°C (82°F)
Economy	When asleep or away from home		17.0°C (63°F)	20.0°C (68°F)
Vacation	During prolonged absence		10.0°C (50°F)	10.0°C (50°F)

To use a preset temperature:
Briefly press the appropriate preset temperature button (, or ). The preset temperature will become the current setpoint and its icon will appear on the screen.

To modify a preset temperature:

Press one of the buttons to display the desired temperature.
Press and hold the appropriate preset temperature button (,or ) until its icon is displayed.

Default schedule

The schedule consists of 4 periods per day, which represents a typical work day. The Comfort ( ) preset temperature is automatically used in Periods 1 and 3 and the Economy ( ) preset temperature in Periods 2 and 4. You can program the thermostat to skip (cancel) the periods that do not apply to your situation. For example, you can skip periods 2 and 3 for the weekend.
NOTE: If you wish to use only 2 periods, use the following combinations: “1 and 4” or “2 and 3”. Early Start (see page 9) will not work with any other combinations. You can have a different program every day; i.e., each period can start at a different time every day. The thermostat has been programmed with the following schedule.
