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
Heat Anticipator: 0.1A to 1.0A
Cool Anticipator: 0 to 1A
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.

* 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.
