HONEYWELL T4700A CHRONOTHERM (01) PDF MANUAL

Digital temperature sensing and control for energy efficient precision operation.

Flexibility of 5-1-1 day or 7-day programming.

Exceptional comfort control of resistance-rated heating equipment.

Patented CoolSwitch™ design offers a long service life.

Night and day setback of space temperature can save up to 29 percent of the energy used to heat a controlled zone.

Offers up to a 12 percent energy saving during comfort periods compared with conventional bi-metallic electric heating thermostat, according to the Electric Power Research Institute.

T4700A: SPST; makes heating circuit on temperature fall.

T4700B: DPST; makes heating circuit on temperature fall. Breaks both sides of 240 volt line with switch in OFF position.

Operating Range: -20 to +104°F (-30° to +40°C).

Control Range: 45 to 80°F (7 to 27°C) in 1° increments. Factory set at 16°C (61°F).

Electrical Ratings (Noninductive): 3800W, 16A maximum; 500W, 2A minimum at 240V, 60 Hz.

Wiring: 6 in. (150 mm) stranded copper leadwires, suitable for connection to aluminum wiring if approved special service CO/ALR connectors are used.

Sensing Element: Electronic thermistor.

Switching: Patented CoolSwitch®.

When the thermostat is first powered up (or after eight hours of continuous power loss), the display blinks for two seconds and then undergoes a self-test — while 00E displays for about 15 seconds.

This is followed by the display flashing (1:00 PM); the internal checkout is complete and the thermostat is ready to be programmed.

The thermostat defaults to a normal non-programmable 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.

Table 1. Preset Factory Schedule for 7-days.

Event	Time	Temperature
WAKE	6:00 AM	70°F (21°C)
LEAVE	8:00 AM	61°F (16°C)
RETURN	6:00 PM	70°F (21°C)
SLEEP	10:00 PM	61°F (16°C)

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 the (+) key with the cover open). This resets only the clock; the programmed schedule is retained.

The thermostat is flexible and can be programmed to meet your lifestyle. Four time periods are available:

WAKE is the time the thermostat turns on the equipment after an energy saving period. When deciding what time to set for your WAKE period, include extra lead time, depending on the outside temperature and your equipment response time, to give the equipment time to adjust the temperature before you get up.

LEAVE is the time you can set for an energy-saving temperature while you are away at work or school.

RETURN is the time the thermostat turns on the equipment after an energy saving period. When deciding what time to set for your RETURN period, include extra lead time, depending on the outside temperature and your equipment response time to give the equipment time to adjust the temperature before you arrive home.

SLEEP is the time you can set for an energy-saving temperature while you are sleeping.

IMPORTANT: After programming is complete, the device reverts to normal Run mode within five minutes, if no key was pressed, and any new setting is stored in its memory. Always press the keys with your fingertip or similar blunt tool. Sharp instruments like pens and pencil points can damage the keys.

Follow these steps:

Step	Press This Key	Description
1	Prog	Displays day of the week.
2	+ or –	Displays changed day of the week.
3	Prog	Displays hour of the day.
4	+ or –	Displays changed hour of the day.
5	Prog	Displays minute of the day.
6	+ or –	Displays changed minute of the day.

Follow these steps:

Step	Press This Key	Description
1	Prog	Scrolling through the display shows the first day to program, beginning with Monday.
2	Prog	Displays WAKE time.
3	+ or –	Displays changed WAKE time in ten-minute increments.
4	Prog	Displays WAKE setpoint temperature.
5	+ or –	Displays changed WAKE setpoint temperature.
6	Prog	Displays LEAVE time.

NOTE: Continue through LEAVE, RETURN, and SLEEP periods using the same procedure to set the time and temperature for each period.

Follow these steps:

Step	Press This Key	Description
1	Prog (until desired day to copy FROM is shown)	Selects and displays the day to be copied; for example, Monday.
2	Func	Displays COPY FROM day (Monday).
3	+	Displays COPY TO day (Tuesday). Use + or – to select the target day.
4	Func	Enters the program. (NOTE: Repeat sequence to copy additional days.)

NOTE: To exit the programming mode: 1) press and hold the Prog key for three seconds and the display returns to Run mode, or 2) during the programming session, after five minutes elapsed time with no program change, the display reverts to Run mode. This does not change any of the programmed steps. Simply keep pressing the Prog key until you arrive at the desired mode.

To temporarily override the program:

Step	Press This Key	Description
1	+ or –	Changes to TEMPorary mode and controls at a new temperature until the next scheduled event (for example, RETURN).

To indefinitely override the program (Hold Mode):

Step	Press This Key	Description
1	Func	Changes to HOLD mode and controls at the HOLD temperature indefinitely.
2	+ or –	Increases or decreases the HOLD temperature.
3	Func	Changes from the HOLD mode to the RUN mode.

Use the following steps to program additional functions:

Function	Press This Key	Description
Begin sequence to convert display or mode.	Press and hold both the Prog and Func keys.	Initially a random four-digit/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.	Display shows °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.	Display shows 511d. Press (+) key to change mode to 7-day programming (or back to 5-1-1 programming). Then adjust using the (+) or (-) keys.

NOTE: To exit the programming mode: 1) press and hold the Prog key for three seconds and the display returns to Run mode, or 2) during the programming session, after five minutes elapsed time with no program change, the display reverts to Run mode. This does not change any of the programmed steps. Simply keep pressing the Prog key until you arrive at the desired mode.

1. Press the (+) key until the setpoint displayed exceeds the room temperature to verify that the thermostat is turning on the baseboard heater.

2. When the (°) symbol is flashing, feel for warmth near the heating element that indicates that the unit is generating heat.

3. Press and hold the Prog key until the thermostat returns to the RUN mode.

This indicates the connected load exceeds 3800W. Ensure total baseboard wattage connected does not exceed 3800W. A fire hazard exists if wattage exceeds 3800W. Push Reset key to clear and reset clock.

This indicates a power failure was detected. Push Reset key to clear and reset clock.

The cause is unknown. Push Reset key to clear and reset clock. If problem persists, call Honeywell Customer Response Center at 1-800-468-1502.
