THERMOSTAT LOCATION

To ensure proper operation, the thermostat should be mounted on an inside wall in a frequently

occupied area of the building. In addition, its position must be at least 18" (46 cm) from any out-

side wall, and approximately 5, (1.5 m) above the floor in a location with freely circulating air of

an average temperature.

Be sure to avoid the following locations:

•

behind doors or in corners where freely circulating air is unavailable

•

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 or water pipes or warm air stacks in an adja-

cent partition, or by an unheateci/uncooled area behind the thermostat

•

where its operation will be affected by the supply air of an adjacent unit

•

near sources of electrical interference such as arcing relay contact

REMOVING THE THERMOSTAT FROM THE SUBBASE

Insert a flat blade screwdriver or ooin 1/8"

into the slot located in the bottom center of

the thermostat case and twist 1/4 turn.

force than others when separating due to

the number of terminals used.

Swing the thermostat out from the bottom.

Lift the thermostat up and off the subbase.

Place the ectangular opening in the sitbase over the equipment control wires protruding from

the wall and using the subbase as a template, mark the location of the two mounting holes

(exact vertical mounting is necessary only for appearance).

Use the supplied anchors and screws for mounting on drywall or plaster; drill two 3/16" (5mm)

diameter holes at the marked locations; use a hammer to tap the nylon anchors in flush to the wall

surface and fasten subbase using the supplied screws. {Do not over tighten])

Connect the wires from your system to the thermostat terminals as shown in the wiring diagrams.

Carefully dress the wires so that any excess is pu

-led back into the wail cavity or junction box.

Ensure that the wires are flush to the plastic subbase. The access hole should be sealed or

stuffed to prevent drafts from affecting the thermostat.

DESCRIPTION OF THE DIP SWITCH FUNCTIONS

2 Events or 4 Events Per Day (300-225, 300-227. 300-229)

Your thermostat can be set to either 2 events or 4 events per day.

2 events will allow you to program a Day

setting and a Night ( setting.

4 events will allow you to program Morning 2L, , Day

Evening

and Night ( settings.

Smart Fan

(300-225, 300-227, 300-229)

When the Smart Fan switch is in the ON position and the fan

has been energized (during

the occupied program), the thermostat will keep the fan running continuously during the occu-

pied programs and automatically cycle the fan with a call for heating or cooling during the unoc-

cupied program.

NOTE:

The unoccupied program is the Night program.

2 Minute or 4 Minute Minimum On Times

Keypad Lock

Place the switch in the locked position to lockout all buttons except the OUTDOOR button.

Plenum Fan Switch

(300-224, 300-225, 300-229)

OFF - Fan comes on immediately with heat (used on electric heat).

ON - Fan is controlled by the system (used on gas/ail heat).

Standard/Add-on Heat Pump

(300-226, 300-227)

For most heat pump applications, this switch should be left in the standard position. This will

allow the compressor and the auxiliary heat to be on simultaneously. For add-on heat pumps,

or heat pumps that require fossil fuel kits, move this switch to the add-an position. This will turn

off the compressor with a call for auxiliary heat.

Single or Multistate

(300-227, 300-229)

For equipment with a single compressor (2 heat/1 cool

for 300-227 or 1 heat/1 cool for

300-

229}, switch to single stage. For equipment with two compressors (3 heat/2 cool for 330-227 or

2 heat/2 cool for 300-229), switch to multistage.

LED #1

(300-226, 300-227, 300-229)

Switch ON will energize the LED light pipe at the top of the thermostat plus the filter indicator on

the display. This indicates the filter needs to be changed.

LED #2

(300-226, 300-227, 300-229)

Switch ON will energize the LED light pipe at the top of the thermostat plus the wrench indicator

on the display. This indicates service is

required.

FEATURES

Remote Sensor FIS1 — R52 - RS-IN

The thermostat is designed to accept the remote sensor (10-528) which will allow you to locate

your thermostat in an area away from view.

LED Auxiliary Heat Indicator

(300-226, 300-227)

Your thermostat is equipped with an LED that indicates when the system has engaged auxiliary

heat mode. It is the center (red) LED.

Add-On Heat Pumps

(300-226,

300-22 7)

Your thermostat is equipped to enhance the performance of an add-on heat pump.

In most applications, the thermostat will perform the function of a fossil fuel kit.

To select Add-On, place switch (10

for 300-226,

for 300-227)

to the ON position. The ther-

mostat will turn off the compressor with a call for AUX heat. When the switch is set to

normal, the thermostat allows the compressor and the AUX heat to be on simultaneously.
