Programmable Thermostat

INSTALLATION

Step 1 — Thermostat Location —
should be mounted:
• approximately 5 ft from the floor
• close to or in a frequently used room, preferably on an
inside partitioning wall
• on a section of wall without pipes or ductwork
The thermostat should not be mounted:
• close to a window, on an outside wall, or next to a door
leading to the outside
• where exposed to direct light and heat from a lamp, the
sun, a fireplace, or any other temperature-radiating object
which may cause a false reading
• close to or in direct airflow from supply registers or
return air grilles
• in areas with poor air circulation (such as behind a door
or in an alcove)
Step 2 — Set DIP Switches —
line package (DIP) switches, remove the thermostat door from
the front and unhinge the back half of the thermostat from the
front half.
There are 4 small DIP switches in the upper right of the cir-
cuit board which must be configured by the installer. The ON
position is indicated by small letters on the switch. Ignore the
numbers (1-4) on the switches. The switch designation (A-D)
is printed on the circuit board above the switches. To change a
switch position, use the corner of a small screwdriver to slide
the switch ON or OFF.
Set the DIP switches before installing the thermostat and
record the settings on page 16. Once switches are set, do NOT
reassemble the halves of the thermostat. The back half will be
mounted to the wall.
ZONING SELECT — SWITCH A (Active on All Models) —
Switch A controls the 4 cycles per hour limit and 5-minute
compressor timeguard that MUST be enabled for normal oper-
ation. For zoning applications, turn the switch to ON and can-
cel the timers as the zone control center performs these timing
functions.
TO SET:
OFF — Normal operation, factory default
ON — Zoned installations only

SETBACK RECOVERY — SWITCH B (Active on All
Models) — Use Switch B to select either normal or smart re-
covery from setback. Normal recovery changes to the new set
point at the programmed time. Smart recovery, which is active
in heating mode only, starts earlier and adjusts the set point
slowly so that room temperature will arrive at the programmed
temperature at the programmed time.
TO SET:
OFF — Smart recovery, factory default
ON — Normal recovery
HP/AC SELECT — SWITCH C (Active on 1200 and 1300
Models Only) — Use Switch C to select between AC and HP
installations. The 1200 and 1300 models have an extra relay to
control the HP reversing valve. When a 1200 model thermostat
is placed in AC mode, this extra relay is converted to a second
stage heat output. This allows thermostat control of 2-stage fur-
naces or 2-stage strip heat with AC systems (AC mode wiring
also uses W rather than Y for first-stage heat).
TO SET:
OFF — HP applications (extra relay controls reversing valve),
factory default
ON — AC applications (extra output can be used for 2-stage
heat)
INTELLIGENT HEAT STAGING SELECT — SWITCH D
(Active on 1300 Models Only) — Use Switch D to convert a
2-speed heat pump thermostat with 1 stage of auxiliary heat
into a 1-speed heat pump thermostat with 3 stages of auxiliary
heat for additional heating capacity. It requires selected heaters
with 2:1 ratio element sizes plus a variable-speed fan coil. Re-
fer to fan coil literature for details.
TO SET:
OFF — Normal 2-speed operation, factory default
ON — Intelligent 3-stage heat with a variable-speed fan coil
Step 3 — Install Thermostat
Before installing thermostat, turn off all power to the
unit. There may be more than one power disconnect.
Electrical shock can cause injury or death.
4. Turn off all power to unit.
5. If an existing thermostat is being replaced:
a. Remove the existing thermostat from the wall.
b. Disconnect wires from the existing thermostat. Do
not allow the wires to fall back into the wall. As
each wire is disconnected, record wire color and
terminal connection.
c. Discard or recycle the old thermostat.
NOTE: Mercury is a hazardous waste and must be disposed of
properly.
6. Locate the 2 mounting holes (1 on each side of the
large hole) in the back half of the thermostat, which
are already exposed from unhinging the front and back
halves to set the DIP switches.
7. Route thermostat wires through the large hole in the
back half of the thermostat. Remove the outer sheath
from the wires for added flexibility. Standard solid or
multi-conductor thermostat wire should be used from
the thermostat to the base unit. Size and length consid-
erations are as follows: for a maximum run length of
36 ft, use 22 AWG (American Wire Gage) wire; for a
maximum run length of 100 ft, use 18 AWG wire.
