Mr. Heater TE8001 Operation Manual

The TE8001 is an electronic non-programmable thermostat. It is designed to work with most
standard single stage heating and/or single stage cooling systems. These include single or dual
transformer 24 VAC gas, oil or electric heating, and 24 V AC cooling systems. This thermostat
is also compatible with single stage heat pumps.
The TE8001 is designed to operate entirely on two AAA alkaline batteries, or 24 volts from the

heating/cooling system’s transformer, using the batteries only for memory back up.

FORM: 8063
Rev: -

Installation:

Important: Read the entire instructions before beginning installation. Failure to follow these
instructions could result in personal injury and/or property damage.

Location:

The thermostat should be mounted 4 to 5 feet above the floor in a location where it will be
exposed to average room temperature. The thermostat must not be mounted where it will be
effected by a source of heat such as lamps, sunlight, fireplaces, pipes, registers, etc..., or
sources of cold such as windows, doors, drafts, etc... The thermostat must not be mounted on
an exterior wall, behind a door, or in an alcove. Such locations will inhibit the thermostat’s

ability to accurately control room temperature

Removing existing thermostat:
Caution:

Power must be disconnected before removing existing wiring connections from thermostat to
prevent possible electrical shock and/or equipment damage. All wiring must conform to local
and national electrical codes and regulations.
1: Remove existing wiring by writing down each of the wire’s colors and the designation of the
terminals that they are connected to. If more than one wire has the same color, tag the wire
with some form of identification.
2: Remove wires from thermostat.

Mounting:

This thermostat may be mounted directly to the wall, by using the mounting screws supplied.
Remove base from front section, by opening battery door, remove batteries. Pull case apart.
T o mount directly to a wall use holes located in top and bottom of case.
Pull wires through hole in center of case.

Do not depend upon the thermostat as the sole means
of disconnecting power when installing or servicing the product it is
controlling. Always disconnect power at the main circuit breaker as
described above. Failure to do so may result in fatal electric shock.

Option Jumpers:

The option jumpers are located to the right edge of the circuit board, directly
above the white relay. These jumpers are set at the time of installation. The
following table lists the 4 options. The factory settings are in bold. The options
include:

Option Jumper On Jumper Off
C Celsius Fahrenheit

1F Closer Differential Wider Differential
HBY No Heat Delay 5Min. Delay
CBY No Cool Delay 5Min. Delay

Fan Option:

An additional option jumper (J1) is located between the two switches, near the
bottom edge of the circuit board.. This selects fan operation for single transformer
systems: The factory setting has the jumper on the middle and lower two pins
(TH). This activates the fan whenever the thermostat turns the cooling on. For an
electric heat system, place the jumper on the middle and upper pins (H/C), which
will allow the fan to turn on whenever the thermostats turns on the cooling or the
heating.

UT Thermostats Installation Instructions

Installation Instructions:

Please read all the instructions carefully before starting. Leave this
instruction sheet near the thermostat when you are finished.

Specifications:

For use with self-powered 250-750 millivolt generating systems and 2
wire (UT1001, Heating Only), or 3 wire and 6 wire (UT3001, Cooling
Only and UT8001, Heat/Cool) electric, gas or oil systems equipped
with 24 VAC controls.
Electrical Rating: 24-30 VAC (or 250-750mV)
Heat Anticipator: 0.1A to 1.0A (Adjustable)
Cool Anticipator: 0 to 1A (Fixed)

Selecting Thermostat Location:

For accurate temperature control and comfort, selecting the proper
location is very important.
If this is a new installation, the guidelines listed below should be
followed. When replacing an old thermostat install the new
thermostat in the same location unless these guidelines suggest
otherwise.
1: Locate the thermostat on an inside wall of a frequently occupied
area (ie: family room) about 4-5 feet above the floor.
2: Do not install the thermostat where there are unusual sources of
“heat”, such as direct sunlight, or near a radiator, duct vent, lamp, or
fireplace.
3: Do not install the thermostat where there are unusual “cooling”
sources , such as an outside wall, drafts from doors, windows,
stairways, or duct vents.
4: Do not install the thermostat where the air circulation is poor, such
as in a corner, alcove or behind a door.

Removing Old Thermostat:

1: Shut off electricity to your heating and/or cooling system by
removing the associated fuse or switching the circuit breaker off.
2: Remove the cover of the old thermostat. If you do not see the
system wires, then you will have to remove another section of the
thermostat. This may require the use of a screwdriver.
3: Observe the terminal markings of each wire. Label each wire with
tape indicating the appropriated terminal markings to allow easy
installation of the UT thermostat.
4: After you have labeled the existing wires, remove the wires from the
terminals.
5: Remove the old thermostat base from the wall.

Installing the UT thermostat:

1: Hold the UT thermostat in one hand. Carefully remove cover from
the thermostat base by pulling upward gently. Remove any shipping
material present.
2: Position thermostat base on wall and carefully feed existing wires
through opening. The UT can be position horizontally or vertically. If
to be installed in the horizontal position, the adjustment lever must
extend out the right side of the thermostat. If installed in the vertical
position the lever must extend out the bottom of the thermsotat.
3: After you have finished locating the UT thermostat, you can mark
the placement of the two screw holes for mounting. Set aside
thermostat base.
4: If you are mounting the thermostat on plasterboard or another type
of soft material, use plastic anchors. Use a 3/16" drill to make two
holes where the mounting holes have been marked. Insert anchors
into holes.

5: Feed the wires back through the base, then mount to the wall with
supplied screws.
5: Connect the wires to their associated marked terminals. (See Chart
if old and new terminals do not match exactly)
7: Check all connections so that adjacent wires are not touching.
8: Replace cover onto base by snapping it into place.
9: Make sure the system switch is in the OFF position until you are
ready to check your wiring.

Old Thermostat New Label Description

M, 4, RH, R5, or 5 RH or R Transformer Hot for Heat.*

V, or RC RC or R Transformer Hot for Cool.*

H, W, or 4 W Heating Control (valve, relay, etc.)

Y, or Y6 Y Cooling Control (valve, relay, etc.)

F or G G Fan Control. (See internal fan option)

* For separate RH and RC wires, you must remove the factory
installed J2 jumper.

Internal Fan Option (UT8001 only)

For typical gas or oil heating systems, place the J1 jumper on the G/O
pins to allow natural system delay in fan operation during the heat
mode.
If the heating system requires the fan to come on immediately with the
heat (ie: electric heating systems), then place the J1 Jumper on teh E
pins.
G/O – Fan turned on by heating system.
E – Fan turned on by thermostat in heat mode.

Setting the Heat Anticipator: (UT1001 & UT8001 models)

To help provide accurate control of furnace heat cycles, you must
adjust the anticipator setting of the UT thermostat to match the
current rating of the system control device. For Millivolt operation
the heating anticipator setting must be place over the MV.

This setting can be found by looking at the setting used on the
previous thermostat. If you are unable to find it, the information can
be found in the owner’s manual for the heating system. You can also
find the information printed on the control device at the furnace. The
control device is normally a gas valve, relay or pilot generator
located behind the furnace cover.
If the current rating is still unavailable, connect an AC amp meter
between the RH and W terminals on the thermostat. Let the system
operate through the amp meter for at least one minute before taking
the reading. The reading can then be used as the setting for the
anticipator.
