Ritetemp 8082 programmable Thermostat

Caution
To avoid electrical shock and to prevent damage to the furnace, air conditioner, and thermostat, disconnect the power supply before beginning work. This can be done at the circuit breaker, or at the appliance.

Tools
You will need #1 Phillips screwdriver (small) and Drill with 3/16-in. (4.8mm) bit for this installation.

1 Location

• On replacement installations, mount the new thermostat in place of the old one if possible.
• On new Installations, follow the guidelines listed below.
• Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and in a room that is used often.
• Do not install it where there are unusual heating conditions, such as: in direct sunlight; near a lamp, radio, television, radiator register, or fireplace; near hot water pipes in a wall; near a stove on the other side of a wall.
• Do not locate in unusual cooling conditions, such as: on a wall separating an unheated room; or in a draft from a stairwell, door, or window.
• Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
• Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open door.
• Do not install the unit until all construction work and painting have been completed.
• This thermostat does not require leveling.

CAUTION
Your thermostat is a precise instrument. Please handle it with care. Turn off the electricity to the appliance before installing or servicing the thermostat or any part of the system. Do not
turn the electricity back on until work is completed. Do not short (jumper) across electric terminals at the control on the furnace or air conditioner to test the system. This will damage the thermostat and void your warranty. All wiring must conform to local codes and ordinances. This thermostat is designed for use with 24-volt AC and millivolt systems. The thermostat should be limited to a maximum of 1.0 amps; higher amperage may cause damage to the thermostat.

2 Remove the old unit

• Switch the electricity to the furnace and air conditioner OFF, then proceed with the following steps.
• Remove the cover from the old thermostat. Most are snap-on types and simply pull off. Some have locking screws on the side or front. These must be loosened. Note the letters printed near the terminals. Attach labels (enclosed) to each wire for identification.

Caution
Read the instructions carefully before removing any wiring from the existing thermostat. Wires must be labeled before they are removed. THERE IS NO COLOR CODE FOR WIRES. When removing wires from their terminals, ignore the color of the wires since these may not comply with the standard.

• CAREFULLY LABEL the wires one at a time, remove only if labeled.
• Make sure the wires do not fall back inside the wall. Wind them around a pencil to keep them from falling.
• Loosen all screws on the old thermostat and remove it from the wall.
• Fill the wall opening with non-combustible insulation to prevent drafts.

3 Mount the 8085

• Separate front from back of unit. Press up on the catch on bottom of thermostat and swing the body away from the base, lift up to remove the body from the base.
• Hold the base against the wall, with the wires coming through the opening below the terminal block.
• Position the base for best appearance. (If you chose to use the optional wall plate, hold the wall plate against the wall, with the wires coming through the opening. Then pull the wires through the opening in the base unit. Position the base unit for best appearance.)
• Attach the base to the wall with the two screws provided.
• If you are mounting the base to sheet rock or
• if you are using the old mounting holes, use the plastic anchors provided. Drill a 3/16- in.(4.8mm) hole for the insert at each screw location, then mount the base.

4 Before you Connect Wires
Please follow these guidelines for safe and secure wire connections

• Strip insulation 3/8 in. (9.5mm) from wire ends.
• Take care not to damage the labels for each wire in handling.
• Connect labeled wires only to a terminal with corresponding letter.
• Bend the wire slightly, insert the wire under the contact plate and tighten the screw down onto the wire.

Caution
Do not allow wires to touch each other or parts on thermostat. Wires must be routed through the hole in the back plate, below the terminal block, or they will hit par ts on the cover.

Optional Wire Connections
Determine which step-by-step wiring diagram you should use. Make sure your wires are labeled. This may require you to find the ‘other end’ connection for each wire on your heating or air conditioning equipment and read the label there. If you have a wire make “C” its connection is optional. If you do connect it, the thermostat will draw power from the C wire and this will extend battery life.

5 What Wires Do You Have?

• R – Single source power for heat/cool
• Note: R connects to both RC and RH using the Orange jumper
• RH or 4 – HEATING POWER
• RC – COOLING POWER
• W – HEATING CONTROL
• G – FAN RELAY
• C – Common side of Heating Power
• Y – COMPRESSOR
• O – DAMPER OR CHANGEOVER VALVE (POWERED IN COOL)
• B – DAMPER OR CHANGEOVER VALVE (POWERED IN HEAT)

When you have finished making connections. hook the top of the body onto the base, swing the body down, and snap the body onto the base

5 Install Batteries

• The 8082 requires batteries to operate your furnace and retain its programming in memory.
• Switch MODE switch to OFF and the FAN switch to AUTO.
• Remove the unit from the wall turn it over and install 2 AA alkaline batteries according to the polarity noted in the compartment. Initially, all LCD segments will go on.
• Press the RESET button to clear transient program memory.
