Programming Thermostat Factory Set Programming The thermostat defaults to a normal nonprogrammable thermostat at power-up, indicated with Hold appearing in the display. Pressing the Prog key once enters the programming mode. The thermostat is preset with a factory set schedule for 7 days, see Table 1.
Thermostat Reset your equipment response time, to give the equipment time to adjust the temperature before you get up. The T4700 can be reset to its default settings (Table 1) by inserting a bent paper clip or similar wire into the small hole on the front of the thermostat (next to to the (+) key with the cover open). This resets only the clock; the programmed schedule is retained. LEAVE is the time you can set for an energy-saving temperature while you are away at work or school.

NOTE: Continue through LEAVE, RETURN, and SLEEP periods using the same procedure to set the time and temperature for each period.
Table 4. Copying Schedules to Another Day. Step Press This Key Display Shows Description 1 Selects and displays the day to be copied; for example, MOnday. 2 Displays COPY FROM day (MOnday). 3 Displays COPY TO day (TUesday). 4 Enters the program. (NOTE: Repeat sequence to copy additional days.
Table 5. Overriding a Program. Step Press This Key Display Shows Description Temporarily Overriding a Program Temporary (TEMP) Mode Changes to TEMPorary mode and controls at a new temperature until the next scheduled event (for example, RETURN). Indefinitely Overriding a Program Hold (HOLD) Mode Changes to HOLD mode and controls at the HOLD temperature indefinitely. Increases or decreases the HOLD temperature. Changes from the HOLD mode to the RUN mode.
Table 6. Programming Additional Functions. Function Press This Key Display Shows Description Begin sequence to convert display or mode. Press and hold both the Prog and Func keys. Initially a random fourdigit/letter display occurs (for example, FF FF). Continue to press Prog key until temperature symbol appears. Convert to °C or °F. Press Prog key a second time to display °C. Use (+) key to change to °F if desired (or °F to C°). Convert 5-1-1 to 7 day. Press Prog key a third time to display 511d.
Checkout 1. After initial thermostat powerup (or after eight hours of continuous power loss), the display blinks for two seconds, then runs a self-test (when 00E displays) for 15 seconds. When the internal self-test checkout is complete, the display flashes (1:00 PM) and the thermostat is ready to be programmed. 2. 3. Press the (+) key until the setpoint displayed exceeds the room temperature to verify that the thermostat is turning on the baseboard heater.
