Then release DAY button. To change the time format from 24 hrs. to 12 hrs. and back, maintain HOUR button pressed down as RESET button is being pressed on and released. Then release HOUR button. To change the heating control from proportional to on/off and back, maintain MIN button pressed down as RESET button is being pressed on and released. Then release MIN button. • TO SET TIME AND DAY Press on DAY, HOUR and MIN buttons to adjust time and day. • TO RECORD THE HEATING PROGRAMS Set the operating mode to AUTO. Use the PGM button to select the program to be recorded or modified. Once the program is selected, use HOUR and MIN buttons to set time and or to select temperature setting. • TO RECORD THE ECONO PROGRAMS Set the operating mode to ECONO. Use the PGM button to select the program to be recorded or modified. Once the program is selected, use DAY, HOUR and MIN buttons to set time and or to select temperature setting. • OPERATING MODES To select an operating mode, use MODE button. AUTO: Runs the program. or shows temperature setting and can override temporarily your programming. MAN: Maintain the selected temperature. or change the temperature setting. ECONO: Maintain a temperature setting up to the user's pre- programmed day and time. or shows temperature setting and can override temporarily your programming. NOTE: To access the programmable keyboard, remove the cover by placing your fingers to the right side of the thermostat and pull toward you. INSTALLATION Note: The "Problems and Solutions" section at the end of this user's guide will help you to correct your problems during the installation. This thermostat has been designed to operate with any installation which has a RESISTIVE load not exceeding 2500 W @ 240 VAC or 1250 W @ 120 VAC such as electric baseboards, radiant ceilings and floors, electric convectors, etc. It is not compatible with a low voltage controller used by a central heating system or systems using a contactor or a relay whose current is under 1.0 A. Electricians or experienced technicians should install the thermostat. This thermostat is designed to be used with a self-protected heating system equipped with thermal cut off and circuit breaker. PARTS INCLUDED -One (1) thermostat -Two (2) 6-32 screws, 1 . inches -Two (2) solderless connectors TURN OFF POWER OF THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK. Keep air vents of thermostat clean and free from obstructions. 1) Connecting wires and mounting thermostat Connect the rear thermostat wires to the power supply and to the electric heater wires using solderless connectors for copper wires (there is no polarity for the wires). See schematic diagram. 2-wire installation : Electric baseboard120 / 240 VAC Line Solderless connector for copper wires 4-wire installation : Electric baseboard120 / 240 VAC Line Solderless connector for copper wires Push the excess wire back into the electrical box to prevent interference with the thermostat. Secure the thermostat using the supplied screw. Once the thermostat is properly installed, return power to heating system. Note 1 : All cables and connections must conform to the local electrical code. Note 2 : In normal use at full capacity (2500 W), the housing temperature of the thermostat can reach 35 to 40 °C. WARNING : Special CO/ALR solderless connectors must be used when connecting with aluminum conductors. 2) Options selection Some options have been factory set. Those default settings are : • The temperature is in °C, the heating control is proportional and the time format is 24 hrs. 2.1 Temperature displayed in °C or °F To change the temperature from °C to °F and back, maintain DAY button pressed down as RESET button is being pressed on and released. Then release DAY button. 2.2 Time format displayed in 24 hours or 12 hours To change the time format from 24 hrs. to 12 hrs. and back, maintain HOUR button pressed down as RESET button is being pressed on and released. Then release HOUR button. 400-102-000-A 1/4 2.3 Proportional or ON/OFF heating control This thermostat has been factory set to proportionally control electric baseboards, radiant systems and convectors. Since proportional control uses a fast commutation rate, it is not compatible with fan equipped systems (see characteristics). Also, this control mode could occasionally create light flickering, especially in rural area. You can change the control mode to make it compatible with fan equipped systems or to eliminate the light flickering. To do so, maintain MIN button pressed down as RESET button is being pressed on and released. Then release MIN button. Following this operation, the display will show the fan indicator. To return to proportional control, repeat the same operation. 3) Memory backup In the event of a power failure, an internal circuit will maintain the programming. The display will stay on for 15 minutes. An indicator "LP" will be shown on the display. Beyond this period, the display will turn off. ...
