III. INSTALL THERMOSTAT

WARNING: ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death.

Before installing thermostat, turn off all power to unit. There may be more than 1 power disconnect.

1.Turn OFF all power to unit.

2.If an existing thermostat is being replaced:

a.Remove existing thermostat from wall.

b.Disconnect wires from existing thermostat, 1 at a time. Be careful not to allow wires to fall back into the wall.

c.As each wire is disconnected, record wire color and terminal marking.

d.Discard or recycle old thermostat.

NOTE: Mercury is a hazardous waste and MUST be disposed of properly.

3.Open thermostat (mounting base) to expose mounting holes. The base can be removed to simplify mounting. Snap apart carefully to separate mounting base from remainder of thermostat.

NOTE: If thermostat will not separate, insert a small screwdriver into top slots for ease of opening.

4.Route thermostat wires through large hole in mounting base. Level mounting base against wall (for aesthetic value only—thermostat need not be leveled for proper operation) and mark wall through 2 mounting holes.

5.Drill two 3/16-in. mounting holes in wall where marked.

6.Secure mounting base to wall with 2 anchors and screws provided, (additional anchoring holes available for more secure mounting if needed) making sure all wires extend through hole in mounting base.

7.Adjust length and routing of each wire to reach proper terminal and connector block on mounting base with 1/4 in. extra wire. Strip only 1/4 in. insulation from each wire to prevent adjacent wires from shorting together when con- nected.

8.Match and connect equipment wires to proper terminals of the connector blocks. (See Table 1.)

CAUTION: ELECTRICAL OPERATION HAZARD

Failure to follow this caution may result in equipment damage or improper operation.

Improper wiring or installation may damage the thermo- stat. Check to make sure wiring is correct before proceed- ing with installation or turning on unit.

9.Push any excess wire into wall and against mounting base. Seal hole in wall to prevent air leaks. Leaks can affect operation.

10.Snap case back together.

11.Close thermostat assembly making sure pins on back of circuit board align with sockets in connector.

12.Turn ON power to unit.

NOTE: If a common wire has not been connected, two AA batteries must be used to power the thermostat.

On power up, LCD readout will display AC, HP, A2, or H2 depending on the thermostat model status. See "Power On Check" under "Operational Information" on page 11 for explanation.

IV. SET THERMOSTAT CONFIGURATION

Configuration options are intended to be selected at installation and are normally not modified by the home owner. These options are not discussed in the Homeowner’s Guide and therefore must be made as part of the installation. A special procedure allows entry into the configuration mode. The thermostat will automatically exit this mode if no button is pressed for 3 minutes. While in the configuration mode, up to 14 option choices can be made:

Option 01: Anticipator setting

Option 02: Clean filter setting

Option 03: Fahrenheit or Celsius selection

Option 04: Enable fan (G) on with W/W1 output

Option 05: HP / AC

Option 06: Cooling Lockout (available only if an outdoor air temperature sensor is present)

Option 07: Enable zoning

Option 08: Auxiliary heat lockout temperature adjustment (avail- able only on heat pump systems and if an outdoor air temperature sensor is present)

Option 10: O (reversing valve) ON with Heat or Cool (present on Heat Pump models only)

Option 13: Room temperature offset adjustment

Option 15: Enable AUTO mode

Option 18: Backlight configuration

Option 19: Equipment Present

Option 21: Keypad Lockout

An explanation for each of these and how to enter the configura- tion mode follows.

TO ENTER THE CONFIGURATION MODE:

To enter Configuration Mode, hold the FAN button down for approximately 15 seconds. After the 15 second period, Option ″01″ will appear in the display and the SERVICE icon will be turned on.

NOTE: If the FAN button is pressed again or if no button is pressed for 3 min, the thermostat will exit the configuration mode and return to normal operation. To reenter the configuration mode, the FAN button must be pressed and held for 15 seconds again.

WHILE IN CONFIGURATION MODE:

The display is used to show both the option number and the selection choice within that option.

A. Option 01—Anticipator Adjustment

This adjustment controls the sensitivity and cycle rate of the thermostat. Higher numbers decrease the sensitivity and slow the cycle rate. Lower numbers increase sensitivity and increase cycle
