Description
The TL6120 thermostat can be used to control an electric heating system such as a baseboard heater, a radiant floor, a radiant ceiling, a convector, a fan-forced heater, etc.
Clock and Day Setting
The clock must be set when TIME flashes on the screen.
- Press the
button to set the day. - Use the
and 
buttons to set the clock. - Press the
button to exit.
Automatic (programmable) mode
To use the Automatic mode, press the
button until AUTO is selected (outlined) on the screen. The current period number will appear.
In this mode, the thermostat automatically adjust its temperature setpoint according to the period of the day (wake up, leave for work, return home and sleep).
You can program up to 4 periods in a day. You can set 2 different programs: one for the weekdays (Monday to Friday) and another one for the weekend (Saturday and Sunday).
The thermostat is pre-programmed with the following schedule:
| Period | Monday to Friday | Saturday & Sunday | |||
| Start Time | Temperature | Start Time | Temperature | ||
| 1 | Wake | 6:00 a.m. | 70°F (21°C) | 6:00 a.m. | 70°F (21°C) |
| 2 | Leave | 8:00 a.m. | 62°F (16°C) | — | — |
| 3 | Return | 6:00 p.m. | 70°F (21°C) | — | — |
| 4 | Sleep | 10:00 p.m. | 62°F (16°C) | 10:00 p.m. | 62°F (16°C) |
To temporarily override the current setpoint, set the desired temperature using
the buttons. The new setpoint will be used until the beginning of the next period.
To modify the schedule:
- Press the button until AUTO is selected.
- Press
the button.
Each time you press thebutton, the thermostat displays one of the periods in the following order (from left to right)
Monday to Friday Saturday and Sunday MO TU WE TH FR SA SU 1 2 3 4 1 2 3 4 - Set the start time for the period using the and buttons.
NOTE: To disactivate the period, press the button. Instead of displaying the start time of the period, the thermostat will display –:–. During operation, the thermostat will skip over that period. - Set the temperature for the period using the buttons.
- Repeat steps 2 to 4 for the remaining periods.
- Press the button to return the thermostat to a normal display.
Manual (hold) mode
To use this mode, press the button until MAN is selected (outlined) on the screen. Then, set the desired temperature using the buttons. In this mode, any modification to the temperature setpoint must be done manually.
Economy mode
To use the economy mode, press the button until ECONO is selected (outlined) on the screen. This mode is ideal for weekend residences as it can be used as follows: The temperature is kept at an economy level during most of your absence and is raised to a comfortable level by your usual arrival. If you do not show up, the temperature returns to the economy level until next weekend.
The economy mode has two periods which should be set as follows:
| Period | Temperature Setting | Start Time Setting |
|
1 |
Set to a comfortable level. | Set a time where the temperature starts to rise to reach a comforta- ble level by the time you arrive. |
|
2 |
Set to an economy level. | Set a time where the temperature starts to drop to an economy level if you do not show up. |
The economy mode should be used as follows:
- Place the thermostat in economy mode during your absence.
- When you arrive, place the thermostat in automatic mode or in manual mode before the temperature drops back to the economic level.
- When you leave, switch the thermostat back to economy mode.
To program the two periods of the economy mode:
- Press the button until ECONO is selected.
- Press the button. Period 1 is displayed.
- Set the start day for the period using the button.
- Set the start time using the and buttons.
- Set the temperature for the period using the buttons.
- Press to select period 2.
- Repeat steps 3 to 5 to set the day, time and temperature for period 2.
- Press to return the thermostat to normal display.
Power Outage
During a power outage, the thermostat display remains lit for approximately the first 15 minutes during which the LP (low power) indicator appears. The settings are saved in memory. However, if the power failure exceeds 5 hours, only the thermostat’s clock must be re-adjusted. When power returns, the thermostat returns to the mode of operation preceding the power outage.
Troubleshooting
| PROBLEM | SOLUTIONS |
|
Thermostat is hot. |
Under normal operation, the thermostat housing may reach a temperature between 95°F (35°C) and 104°F (40°C). |
| Wrong temperature is dis- played. | Verify that the sticker on the thermostat’s screen has been removed. If the thermostat is exposed to air draft, eliminate the draft. |
| Wrong time is displayed. | The thermostat was probably without power for more than 5 hours. |
| Temperature does not change according to the programmed schedule. | Check that the thermostat is in automatic mode. Check the schedule and clock settings. |
| The normal display disappears and reappears after a few min- utes. | The thermal protection device on the heater might be open. This can happen if the heater is obstructed by furniture or curtains and has over- heated. |
