WARNING
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. THE INSTALLATION MUST BE PERFORMED BY AN ELECTRICIAN. All cables and connections must conform to the local electrical code. Special CO/ALR solderless connectors must be used when connecting with aluminum conductors. Install the thermostat onto an electrical box. Install the thermostat about 5 feet high, on an inside wall facing the heater. Avoid locations where there are air drafts (such as the top of a staircase or an air outlet), dead air spots (such as behind a door), or direct sunlight. Do not install the thermostat on a wall that conceals chimneys or stove pipes. The thermostat wires are not polarized; either wire can be connected to the load or to the power supply. Always keep the thermostat’s vents clean and unobstructed.
The configuration switches are on the back of the thermostat. The factory settings are indicated by the gray cells in the following table.
SW1 | Early Start a | Off | On |
SW2 | Display format | °C / 24-hour | °F / 12-hour |
SW3 | Cycle length b | 15 seconds | 15 minutes |
SW4 | Keypad lock c | Off | On |
Daylight Savings Time
The thermostat can automatically re-adjust its clock at Daylight Savings Time changeover. When this function is enabled (On), the thermostat switches to Daylight Savings Time on the second Sunday of March and to normal time on the first Sunday of November.
NOTE: The function is disabled (default setting) when the clock loses its setting.

POWER OUTAGE
During a power outage, LP (Low Power) appears for the first minute. Then the screen becomes blank. The settings are stored in memory. After initial
installation, the product must be connected to power for a minimum of two hours to enable the power outage feature. However, if the power failure exceeds 4 hours, only the thermostat’s clock must be re-adjusted. When power returns, the thermostat will return to the mode of operation active before the power failure.
Problem | Solutions |
The thermostat is hot. | Under normal operation, the thermostat housing can reach a temperature between 35°C (95°F) and 40°C (104°F). |
LO is displayed. | The measured temperature is below the display range. The heating is activated. |
HI is displayed. | The measured temperature is above the display range. |
The wrong temperature is displayed. | The thermostat is exposed to air draft. Eliminate the draft. Verify the sticker on the thermostat screen has been removed. |
The wrong time is displayed. | The thermostat was without power for more than 4 hours. |
Temperature does not change according to the programmed schedule. | Check that the thermostat is in Automatic mode. Check the schedule and clock settings. |
LP appears on the screen or the screen is blank despite there being no power outage. | The thermal circuit breaker in the heater is opened. This can happen if the heater is obstructed by furniture or curtain and has overheated, or if the thermal circuit breaker is defective. |
The display looks faded when heating is activated | The heating system is less than the required minimum load. This thermostat cannot be used below that rating. |
The settings cannot be changed. | The settings are locked (see “Configuration” on page 2). |
