GENERAL INFORMATION
To ensure proper operation, the thermostats should be mounted on an inside wall
In a frequently occupied area. Its position must be at least 18" (46 cm) away from
any outside wall, and approximately 5' (1.5 m) above the floor in a location with
freely circulating air of an average temperature. Avoid mounting in the following
locations: Behind doors or in corners. Where direct sunlight or radiant heat from
appliances might affect control operation. On an outside wall, adjacent to, or in line
with, conditioned air discharge grilles, stairwells, or outside doors. Where its
operation may be affected by steam, water pipes or warm air stacks in an adjacent
partition space, or by an unheated/uncooled area behind the thermostat .Where its
operation will be affected by the air supply of an adjacent unit. Near sources of
electrical interference such as arcing relay contacts.
SAFETY WARNINGS AND CAUTIONS
THE INSTRUCTIONS WERE WRITTEN WITH THE ASSUMPTION THAT THE
INSTALLER IS FAMILIAR WITH ELECTRICAL WIRING PRACTICES. IF YOU ARE
UNSURE ABOUT ANY PART OF THESE INSTRUCTIONS CONTACT A QUALIFIED
ELECTRICIAN.
TO AVOID FIRE, SHOCK OR DEATH; TURN OFF POWER AT CIRCUIT BREAKER OR
FUSE AND TEST THAT THE POWER IS OFF BEFORE INSTALLING!
USE THIS DEVICE WITH COPPER OR COPPER CLAD WIRE, WITH ALUMINUM
WIRE USE ONLY WITH DEVICES MARKED CO/ALR OR CU/AL.
THE THERMOSTAT CONTAINS ELECTRONIC CIRCUITRY REPLACING THE
CONVENTIONAL MECHANICAL ANTICIPATOR. IF THE JUMPER IS REMOVED, A
DEDICATED TRANSFORMER IS REQUIRED AT THE 'R' TERMINAL TO POWER
THE LOADS.
THE THERMOSTAT MAY BE USED WITH 24 VOLT DC. THE NEGATIVE SIDE OF
THE DC SUPPLY MUST BE WIRED TO THE 24V (C) TERMINAL.

TO INSTALL
1. Insert a flat blade screwdriver or a coin 1/8" (.13 cm) into the slot located in the
bottom center of the thermostat case and twist 1/4 turn. When you feel or hear
a "click", grasp the case from the bottom two corners and separate from the
sub base. Some models require more force than others when separating due to
the numbered terminals on the sub base.
2. Swing the thermostat out from the bottom and lift the thermostat up and off the
sub base.
3. Place the rectangular opening in the sub base over the equipment control wires
protruding from the wall and, using the sub base as a template, mark the
location of the two mounting holes (exact vertical mounting is necessary only
for appearance).
