Caution
Tools
To avoid electrical shock and to prevent damage to the furnace, air conditioner,
and thermostat, disconnect the power supply before beginningwork.
This can be done at the circuit breaker, or at the appliance.
C A U T I O N
.Your thermostat is a precise instrument. Please handle 
 it with care.
.Turn off electricity to the appliance before installing or 
 servicing thermostat or any part of the system. Do not 
 turn electricity back on until work is completed.
.Do not short (jumper) across electric terminals at  
 furnace control 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.
.On replacement installations, If possible: mount the new thermostat in 
  the same place as the old one.
.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 onthe other side
 of a wall.
.This thermostat does not require leveling.
.Do not locate in unusual cooling conditions, such as: on a wall separating 
 an unheated room; or in a draft from a stairwell, door, orwindow.
.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 has been 
 completed.
You will need a #1 Phillips screwdriver (small) and
a Drill with 3/16-in. (4.8mm) bit for this installation.

IMPORTANT : LABEL ALL WIRES 
BEFORE DISCONNECTING THEM!
3 Mount the 8025
.
Switch electricity to the furnace and  
 air conditioner OFF;
 then proceed with the following steps.
.
Remove cover from 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.
.Label the wires one at a time.You must have all the wires labeled  

before you proceed.With all wires labeled, remove them from the old unit.
.Make sure the wiresdo not fall back insidethe wall. Wind them around a 
 pencil tokeep them from falling inside the wall.
.Loosen all screws on the old thermostat and remove it from the wall.
.Fill wall opening with non-combustible insulation to preventdrafts.
.Separate front from back of unit.
.Hold the back and optional wall plate against the
 wall and mark new screw holes on the wall.
 After drilling holes, reposition the two units with the 
 wires coming through the central opening  

(below the terminal block). Again, ensure 
 wires do dot fall back behind wall.
.Fine position the two parts so that wall plate 
 covers blemishes from old thermostat.
 Using screws provided, anchor back unit 
 and wall plate to wall.

Please be aware of the following power options.
1) The 8025 can run on batteries only. (2AA Alkaline) 
The batteries will last well over 1 year. If the batteries are not replaced the
thermostat will stop working.
2) The 8025 can run on the C wire if available. 24VAC ONLY
As shown in the wiring diagrams, The C wire is the other side of the 24VAC
heating transformer. If the C wire is used, the batteries are then for AC power loss
only and will last much longer.The thermostat will continue working if the batteries
die.
5 Install Batteries
The 8025 requires batteries to operate your
furnace and retain its programming in memory.
Switch MODE switch to OFF and the FAN switch to
AUTO.
ï Insert 2 AA alkaline batteries according to the polarity
noted in the compartment.
ï Press the RESET button to clear transient program
memory. Initially, all LCD segments will go off.
NOTE: Replace the batteries when this LOW battery indicator
appears on the display or once a year. When replacing batteries,
you have approximately 30 seconds before your custom
program is lost.

REFER to the back of the Control Unit:
ï If you have Electric Heat or a Heat
Pump (without auxiliary heat) you
must place the Gas/Electric jumper in
the ELECT position (thermostat
controls the Fan).
ï If you have Gas Heat the
Gas/Electric Jumper should be in the
GAS position (furnace controls the Fan ).

Please refer back to these guidelines for safe and secure wire connections.
ï Take carenot to damage the labelsfor each wire in handling.
ï Strip insulation 3/8 in. (9.5mm) from wire ends.
ï Connect labeled wires only to a terminal with correspondingletter.
ï Bend the wire slightly, insert the wire under the screw and
tighten the down onto the wire.
The Wire Label List shows wire
labels used on Ritetemp thermostats.
Please determine what wires you
have and select the correct wiring
diagram to "go to" on pages 8-9.
If you have a HEAT PUMP without
auxiliary heat, select a wiring
diagram on pg 9.
Before you Connect Wires
Caution
Do not allow
wires to touch
each other or parts on unit.
Wires must be routed through
the hole in the back plate, below
the terminal block, or they will
hit parts on the cover.
Make sure your wires are labeled . This is necessary to determine which step-by-step wiring
diagram you should use. This may require you to find the 'ot her end' connection for each wire
on your heating or air conditioning equipment and read the l abel there. 
If you have a Zoned Heating/Cooling system with multiple the rmostats, please refer to our
website at www.ritetemp-thermostats.com for installation not es or call 1-888-515-2585.

The 8025 can be used with most 24 volt; gas, oil or electric heating and air
conditioning systems, single-stage heat pumps, zoned systems, or gas millivolt
heating systems.
It cannot be used with 120 volt heating systems or multistage heat pumps. Ask The
Home Depot for other thermostats to control those
systems.
The 8025 is digital. You can program your desired
Heat and cool temperature set points directly on the
Large LCD display.
You can easily override the set temperatures.
Temperature swing adjustment lets you fine-tune
your system for maximum comfort and energy efficiency.
A 4-minute minimum off time in COOL protects your air
conditioning system from being damaged. Two "AA" batteries (not included) are
used to retain your time and temperature programs, and to run the thermostat.
