Quick reference to screen display
Removing the faceplate
TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN ELECTRICAL PANEL TO AVOID ELECTRIC SHOCK.
WARNING: Installation must be carried out by a certified electrician and must comply with national and local electrical codes.
Loosen the screw holding the faceplate to the base. The screw cannot be completely removed and remains captive on the base. Remove the faceplate from the base by pulling the bottom section.
Wiring
Connect either one of the thermostat wires to the heater wire and the other one to the power supply wire using solderless connectors for copper wires.
NOTE: Special CO/ALR solderless connectors must be used when connecting with aluminium conductors.
Installing the thermostat
- Install the base onto an electrical box.
- Place the FAN switch as follows:
- Place at Yes if you have a fan-forced heater (to prevent premature burnout of the motor).
- Leave at No for better temperature regulation if you do not have a fan-forced heater.
- Reinstall the faceplate on the base and secure it in place with the screw.
- Apply power to the thermostat at the main electrical panel.
Warning: Keep air vents at top and bottom of thermostat clean and unobstructed at all times.
If you change the FAN switch position after you have already applied power to the thermostat, disconnect power to the thermostat at the electrical panel for 3 seconds. The thermostat will use the new setting when you reapply power.
Quick Start-up / Setting the clock and date
When you power the thermostat, the Time menu flashes on the screen. Set the thermostat’s clock and date as follows:
NOTE: At any time, you can access the Time menu by pressing the Select button for 3 seconds and then pressing the Down button once. Your new thermostat is already preprogrammed and is now controlling the temperature!
Automatic (Auto) mode
In Automatic mode, the thermostat follows the programmed schedule (see page 12). To place the thermostat in Automatic (Auto) mode:
Temporary override
While the thermostat is in Automatic mode, you can press the Up or Down button to modify the temperature. The new temperature will be used until the end of the current period. Auto will flash during the override. You can cancel the override by pressing the Select button twice to return to Automatic mode.
Manual (Man) mode
Use the Manual mode if you wish to keep the thermostat at the same temperature indefinitely. In this mode, the thermostat will remain at this temperature until you press the Up or Down button to change it.
To place the thermostat in Manual (Man) mode:
Away mode
The Away mode can be used when you are away for an undetermined length of time. For frost protection while saving energy, the Away temperature is set by default at 15°C (59°F) and cannot be modified by simply pressing the Up or Down button. To modify the Away temperature, see page 16.
NOTE: The Away mode can also be used to prevent tampering of the setpoint temperature in the summer season when heating is not required.
To place the thermostat in Away mode:
Countdown mode
Use the Countdown mode if you wish to keep the same temperature for a predetermined length of time. The choices of countdown times are: 15, 30 or 45 min, or 1, 2, 4, 8, 12 or 18 hr, or 1 to 14 days. At the end of the countdown, the thermostat automatically returns to the previous mode and uses the temperature programmed for that mode. At any time, you can cancel the Countdown mode by pressing the Select button.
To place the thermostat in Countdown mode:
NOTE: At any time during the Countdown mode, you can adjust the count-down time and temperature by perform-ing the steps shown inside the dotted rectangle.
Default schedule
When placed in Automatic mode (see page 8), the thermostat follows the programmed schedule. By default, the thermostat is programmed with the following schedule:
| Monday to Friday
(Mo, Tu, We, Th & Fr) |
Saturday and Sunday
(Sa & Su) |
|||
| Period | Starting time | Temperature | Starting time | Temperature |
| Wake | 6:00 (6:00 AM) | 21.0°C (70°F) | 6:00 (6:00 AM) | 21.0°C (70°F) |
| Leave | 8:00 (8:00 AM) | 16.5°C (62°F) | -:– | – |
| Return | 18:00 (6:00 PM) | 21.0°C (70°F) | -:– | – |
| Sleep | 22:00 (10:00 PM) | 16.5°C (62°F) | 22:00 (10:00 PM) | 16.5°C (62°F) |
The schedule consists of 4 periods per day, which represents a typical work day. However, you can program the thermostat to skip (cancel) the periods that do not apply to your situation. For example, Leave and Return periods are skipped for the weekend in the default schedule. You can choose a different program every day; i.e., each period can have a different starting time and a different temperature every day.
Modifying the schedule
To modify the schedule, proceed as follows:
The days can be selected collectively (Monday to Friday, Saturday & Sunday, or Monday to Sunday) or individually.
To skip a period: When the hour or the temperature of the period is flashing, press the Up and Down buttons at the same time. (Alternatively, set its hour between 23:00 [11:00 PM] and 0:00 [midnight] or its temperature below 5°C [41°F].) Its time and temperature display will be replaced by dashes (-).
NOTE: If you do not press any button for one minute, the thermostat will automatically save any changes you have made and will return to its normal display.
To modify the menu parameters, see page 16.

| LOCK | Keypad lock5 | On / Off | Off |
Away temperature
Set the temperature you wish to use when the thermostat is in Away mode (see page 10).
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.
Early Start
Early Start is used in Automatic mode only. When Early Start is enabled (On), the thermostat determines when to start heating so the desired temperature is attained at the beginning of Wake and Return periods. When Early Start is disabled (Off), heating starts only at the beginning of Wake and Return periods; thus there is a delay before you reach the desired temperature.
Minimum and maximum setpoints
These parameters are used to modify the setpoint range and are applicable in all operating modes.
Keypad Lock
When keypad lock is enabled (On), no other setting change is permitted on the thermostat. The message Lock appears when you try to change any other setting.
Setup procedure
The Configuration menu is shown below.
- Press the Select button for 3 seconds to enter the main menu.
- Press the Up button twice to enter the Configuration (Conf) menu.
NOTE: If you do not press any button for one minute, the thermostat will automatically save any changes you have made and will return to its normal display.
In case of difficulty
| PROBLEMS | SOLUTIONS |
|
Thermostat is hot. |
This is normal. Ensure that the heater capacity does not exceed the thermostat’s maximum load. Keep thermostat air vents clean and unobstructed at all times. |
|
Displayed temperature is incor- rect. |
Remediate if any the following conditions exists:
• The thermostat is exposed to air draft. • The thermostat is located near or above a heat source such as a light dimmer. |
| • The thermostat displays LP
instead of the temperature.
• The screen is blank. |
The thermostat is currently without power. This can happen in either condition:
• There is a power outage. • The thermal protection device on the heater is opened. This can happen if the heater is obstructed by furniture or curtain and has overheated, or if the heater’s thermal protection device is too sensitive. LP appears for the first five minutes. Then the screen becomes blank. |
| TIME is flashing. | The thermostat was without power for more than 4 hours. Set its clock and date (Time menu). |
| Temperature does not change according to the programmed schedule. | • Ensure the thermostat is in Automatic mode.
• Check the clock (Time menu) and the schedule (Prog menu). If the thermostat is config- ured for 12-hour format, ensure that AM or PM appears on the screen. |
