White Rodgers 1F72 5 2 Day Programmable Thermostat Instructions Overview

Summary of Contents

• Page 1: Preparations Assemble tools required as shown below. Failure to follow and read all instructions carefully before installing or operating this control could cause personal injury and/or property damage. To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker until installation is complete. Removing Old Thermostat A standard heat/cool thermostat consists of three basic parts: the cover, the base, and the switching subbase. Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. Disconnect the wires from the old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL. Install new thermostat using the following procedures.
• Page 2: O/B terminal switch selection The O/B switch on this thermostat is factory set to “O” position. If the thermostat requires a “B” terminal, the O/B switch must be moved to the “B” position. This product does not contain mercury. Do not open mercury cells. Take care when securing and routing wires so they do not short to adjacent terminals. Remove the packing material from the thermostat. Connect wires beneath terminal screws on base using appropriate wiring schematic. Drill mounting holes and fasten base loosely to wall. This thermostat does not require batteries to operate. The factory default setting for temperature display is Fahrenheit.
• Page 3: Mounting and wiring Typical wiring diagram for single transformer systems Changeover relay is energized in COOL when O/B switch is in the “O” position. Changeover relay is energized in HEAT when O/B switch is in the “B” position. If safety circuits are in only one of the systems, remove the transformer of the system with no safety circuits. Polarity must be observed. Damage to equipment will occur when power is restored. Accessory relay scheme is required when safety circuits exist in both systems. Two commons must be jumpered together. Jumper required to use a single Aux Heat for both Second Stage Heat and Emergency.
• Page 4: Cooling system operation involves moving the system switch to the cool position. The blower should activate immediately on high speed, followed by cold air circulation. Adjust the thermostat setting to control the temperature. To prevent static discharge, touch the side of the thermostat before using the keys. Familiarize yourself with the thermostat features and button operations before programming. The fan switch can be set to either ON or AUTO to control blower operation. For the heating system, move the system switch to the heat position and adjust the thermostat accordingly. The flame icon indicates the heating system is operating, while the snowflake icon indicates cooling mode. The emergency system bypasses the heat pump for auxiliary heat when needed. Do not operate the cooling system if the outdoor temperature is below 50°F to prevent damage.
• Page 5: Select temperature display adjustment allows you to adjust the room temperature display up to 3° higher or lower. Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature to match your previous thermostat. The current or adjusted room temperature will be displayed on the left side of the display. The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on continuously. The word HOLD is displayed when the thermostat is in the HOLD mode. Displays currently programmed set temperature when the system switch is in the OFF position. The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press HOLD button to select the desired temperature. Energy management recovery causes the thermostat to start heating or cooling early to reach the program setpoint at the specified time. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint. Selecting compressor lockout will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. This is intended to help protect the compressor from short cycling. The factory default setting is Fahrenheit. Clipping a jumper on the circuit board will alter this feature to Celsius temperature setting.
• Page 6: Press TIME once to show the minutes. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program. Program the temperatures to be cooler when the building is vacant or during periods of low activity. Determine the time periods and temperatures for your weekday and weekend programs. You must program four periods for both the weekday and weekend program. You can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs. Use the table at the bottom of the page to plan your program time periods and the temperatures you want during each period. Follow these steps to enter the heating and cooling programs you have selected. Press TIME button once to show the hour only. Heating/Cooling Schedule Plan includes both weekday and weekend programs.
• Page 7: Check your thermostat programming before beginning operation. Move the system switch to the heat position. Press PRGM to view the first weekday heating period time and temperature. Repeat steps to complete weekend heating programming. Press RUN when you have completed entering your heating program. If the outside temperature is below 50°F, disconnect power to the cooling system before programming. Move the system switch to the cool position. Follow the procedure for entering your heating program using selected cooling times and temperatures. Your thermostat is now completely programmed and ready to provide maximum comfort and efficiency. For optimum performance, replace batteries once a year with fresh “AAA” alkaline batteries.
• Page 8: Programming your thermostat No heat: Check if the heating system requires service or if the thermostat needs replacement. Diagnostic: Set system switch to heat and raise the setpoint above room temperature. No cool: Ensure the system switch is set to cool and the setpoint is below room temperature. Heat, cool, or fan runs constantly: Check for possible shorts in wiring or thermostat. Furnace cycles too fast or too slow: The location of the thermostat may influence the cycle rate. Thermostat setting and thermometer disagree: Adjust the thermostat thermometer setting by +/-3 degrees. Thermostat does not follow program: Verify AM or PM settings in the program and clock. Blank display and/or keypad not responding: A voltage spike or static discharge may require a reset.
