Installation and Operating Instructions for White-Rodgers 1F86-0471 Thermostat

Important Information from the Manual

The White-Rodgers 1F86-0471 is a single-stage thermostat designed for heating and cooling systems, including gas, oil, electric, and single-stage heat pumps. This document provides instructions for installation, configuration, and operation. Always disconnect power at the main fuse or circuit breaker before beginning installation to prevent electrical shock or equipment damage.

Installation

Removing the Old Thermostat:

• Label each wire with the terminal designation before disconnecting.
• Disconnect wires one at a time and prevent them from falling back into the wall.
• Remove the old base by loosening all captive screws.

Installing the New Thermostat:

• Pull the thermostat body off the base.
• Place the base over the wall hole, mark mounting locations, and drill holes. Use plastic anchors if necessary.
• Fasten the base to the wall using the provided mounting holes.
• Connect wires to the terminal block on the base.
• Push excess wire into the wall and plug the hole with fire-resistant material to prevent drafts.
• Snap the thermostat onto the base.

Configuration Switches

Before operation, ensure the internal switches are set correctly:

• SS/HP Switch: Set to 'SS' for conventional single-stage systems or 'HP' for single-stage heat pump systems.
• GAS/ELEC Switch: Set to 'GAS' for gas/oil systems (thermostat does not power fan on call for heat) or 'ELEC' for electric systems (thermostat powers fan on call for heat).

Installer Configuration Menu

To access the installer configuration menu, ensure the thermostat is in Heat, Cool, or Auto mode, then press the Menu button for at least 5 seconds. Use the Menu button to advance through items and the arrow buttons to change options.

• Reversing Valve Output: Configures the O/B terminal for heat pump applications.
• Cool Savings: An optional energy-saving feature that adjusts the setpoint during high-demand cooling periods.
• Energy Management Recovery (EMR): Allows the thermostat to start heating or cooling early to reach the setpoint at the scheduled time.
• Compressor Lockout: Prevents short cycling by waiting 5 minutes between cooling cycles.
• Temperature Display Adjustment: Allows calibration of the room temperature display by +/- 4 degrees.

Operation

Fan Settings:

• Auto: Runs the fan only when the heating or cooling system is active.
• On: Runs the fan continuously for air circulation or cleaning.

System Settings:

• Heat: Controls heating only.
• Cool: Controls cooling only.
• Auto: Automatically switches between heating and cooling based on indoor temperature.
• Off: Turns off both heating and cooling systems.

Programming

For programmable models, you can set heating and cooling schedules. The thermostat comes with factory-set energy-saving programs. To customize, use the Menu and Schedule buttons to set times and temperatures for different periods (Wake Up, Leave For Work, Return Home, Go To Bed).

Troubleshooting

If the thermostat experiences issues, such as a blank display or erratic operation, perform a reset:

• Remove the wires from terminals R and C (do not short them together).
• Remove the batteries for 2 minutes.
• Replace the wires and batteries.

If the system does not heat or cool, check the fuse/circuit breaker, furnace power switch, and ensure the blower compartment door is properly installed.
