2 wire (UT1001, Heating Only), or 3 wire (UT3001, Cooling Only),
4 or 5 wire (UT8001, Heat/Cool) electric, gas or oil systems equiped
with 24Vac controls.
Electrical Rating: 24-30 Vac
(or 250-750mv)
Heat Anticipator: 0.1A-1.0A
(Adjustable)
Cool Anticipator: 0-1A
(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 sources of
'cooling', 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:
WARNING
If this product is used to replace a device containing mercury, the
purchaser or consumer must ensure that the mercury is properly
managed to comply with state or federal regulations. Additional guidance may be obtained from the manufacterer of the product being
removed or by calling the Director of Enviromental Services.

Inside Tennessee: 1-423-477-4131
These numbers are for assistance in the proper disposal of old
mercury thermostats.
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
thermostat. This may require the use of a screwdriver.
3: Observe the terminal markings of each wire. Label each wire with
tape indicating the appropriate terminal markings to allow easy
installation of the UT thermostat.
4: After you have marked 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 up gently.
2: Position thermostat base on wall and carefully feed existing wires
through openings. The UT can be positioned 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 thermostat.
3: After you have finished locating the UT thermostat, you can mark
the placement of the two screw holes for mounting. Set aside the
thermostat base.
4: If you are mounting the thermostat on plaster board or another type
3
of soft material, use plastic anchors. Use a 16
" drill to make two
holes where the mounting holes have been marked. Insert anchors
into holes.
5: Feed the wire back through the base, then mount to the wall with
supplied screws.
6: 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.

*For seperate RH and RC wires, you must remove the factory
installed Jumper marked J2.
Internal Fan Option (UT8001 only):
For gas or oil heating systems, place the J1 jumper on the G/O
pins to allow natural system delay in the fan operation during the heat
mode.
If the heating system requires the fan to come on immediatly with the
heat (ie: electric heating systems), then place the J1 jumper on the E
pins.
G/O- Fan turned on by heating system.
E- Fan turned on by thermostat in the heat mode.
Setting the Heat Anticipator (UT1001 & UT8001 only):
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 placed over the MV.
Anticipator
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 gfas valve, relay, or a 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.

Checking the Wiring:
Caution! DO NOT jump across the gas valve or relay to test the
thermostat. This will destroy the thermostat and void the warranty.
Heating Only Model (UT1001):
1: Turn on power to the heating system.
2: Adjust the temperature setting on the thermostat to 6°-8° F above
the room temperature. The heating system should turn on. The fan
may take a few minutes to turn on depending on the delay built into
the furnace.
3: Adjust the temperature setting on the thermostat to 6°-8° F below
the room temperature. The heating system should turn off. The fan
may have a delay before it shuts off.
Cooling Only Model (UT3001):
1: Turn on power to the air conditioning system.
2: Place the Cool/Off switch to the Cool position.
3: Adjust the temperature setting of the thermostat to 6°-8° F below
the room temperature. The A/C system should turn on. There may be
a short delay before the fan turns on.
4: Adjust the temperature setting of the thermostat to 6°-8° F above
the room temperature. The A/C system should turn off. The fan may
have a delay before it turns off.
Heating and Cooling Model (UT8001):
1: Turn on power to the heating/cooling system.
2: Place Heat/Off/Cool switch to the Heat position.
3: Adjust the temperature setting on the thermostat to 6°-8° F above
the room temperature. The heating system should turn on. The fan
may take a few minutes to turn on depending on the delay built into
the furnace.
4: Adjust the temperature setting on the thermostat to 6°-8° F below
the room temperature. The heating system should turn off. The fan
may have a delay before it shuts off.
Caution: To avoid damage to the air conditioner, do not operate if
outside temperature is below 50°F. Please refer to the
recommendations of the air conditioner's manufacturer.
5: Place the Heat/Off/Cool switch to the Cool position.
6: Adjust the temperature setting of the thermostat to 6°-8° F below
the room temperature. The A/C system should turn on. There may be
a short delay before the fan turns on.
7: Adjust the temperature setting of the thermostat to 6°-8° F above
the room temperature. The A/C system should turn off. The fan may
have a delay before it turns off.
