THERMOSTAT INSTALLATION

WIRING

Refer to the equipment manufacturer’s instructions for specific system wiring information. After wiring, see INSTALLER MENU for proper thermostat configuration. Wiring table shown are for typical systems and describe the thermostat terminal functions.

Damper Systems
Y| Cooling Relay
G| Fan Relay
W| Heating Relay
C| Common wire for 24V (optional with batteries)

• When both RC and RH wires are present, cut RC/RH jumper (see next page).
• For heat pump systems, add a jumper wire to connect terminals Y and W

Precautions

• Do not exceed the specification ratings.
• All wiring must conform to local and national electrical codes and ordinances.
• This control is a precision instrument and should be handled carefully. Rough handling or distorting components could cause the control to malfunction.

WARNING:

Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazards.
Do not short out terminals on the gas valve or primary control to test. Short or incorrect wiring will burn out the thermostat and could cause personal injury and/or property damage.

CAUTION

To prevent electrical shock and/or equipment damage, disconnect electrical power to system, at main fuse or circuit breaker box,until installation is complete.

1. 1.) Gas/Elec Switch
   If the system is a heat pump or electric furnace, the GAS/ELEC Switch must be set to Elec. If your system is a gas or oil furnace, the switch must be set to Gas.
   2.) O/B Terminal Switch
   The O/B switch on this thermostat is factory set to the O position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in Cool. If the heat pump is installed requires a B terminal, to energize the changeover relay in Heat, the O/B switch must be moved to the B position.
   3.) RC/RH Jumper Wire
   This thermostat electrically connects the RC and RH terminals so a jumper wire is not required. If the application provides a separate wire for RC and RH, clip the RC/RH jumper. This will isolate both terminals so they can be independently used.

INSTALLER MENU

To prevent changes that may affect system performance, this thermostat has an INSTALLER’S MENU and an USER MENU. The INSTALLER’S MENU provides access to every option, while the USER MENU provides access to items that will not affect system performance. To access the INSTALLER’S MENU press the Menu button for 8 seconds. The display will show item 30 in the table below. Use Next and Back to navigate through menu items. Press   to change a menu setting.

TEST EQUIPMENT

Turn on power to the system.
Fan Operation
If your system does not have a G terminal connection, skip to Heating System.

1. Move the fan switch to the On position. The blower should begin to operate.
2. Move the fan switch to the Auto position. The blower should stop immediately.

Heating System

1. Move System Switch to the Heat position.
2. Press  to adjust the thermostat setting to 1° above room temperature. The system should begin to operate and the thermostat will indicate Heat On.
3. Press  to adjust the thermostat setting to 1° below room temperature. The heating system should stop operating and the thermostat should indicate Heat.

Cooling System

1. Move System Switch to the Cool position.
2. Press  to adjust the thermostat setting to 1° below room temperature. The blower should come on immediately at high speed, followed by cold air circulation. The thermostat will indicate Cool On. There can be up to a 5-minute delay. (see INSTALLER MENU, item 50)
3. Press  to adjust the thermostat setting to 1° above room temperature. The cooling system should stop operating and the thermostat will indicate Cool.
   Note:  If Starting Soon is shown on the display, the compressor lockout feature is operating. There will be up to a 5-minute delay before the compressor turns on.(see INSTALLER MENU, item 50)

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.
Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.

TROUBLESHOOTING

| |
---|---|---
Symptom| Possible   Cause| Corrective   Action

No Heat/ No Cool/ No Fan

(common problem)

| 1.) Blown fuse or tripped circuit breaker2.) Furnace power switch to OFF

3.) Furnace blower compartment door panel loose or not properly installed

4.) Loose connection to

thermostat or system

| 1.) Replace fuse or reset breaker2.) Turn switch to ON

3.) Replace door panel in proper position to engage safety interlock or door switch

4.) Tighten Connections

No Heat

| 1.) System Switch not set to Heat2.) Loose connection to thermostat or system

3.) Heating System requires service or thermostat requires replacement

| Verify thermostat and system wires are securely attached.Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes the thermostat should make a soft click sound and “Heat On” should appear on display. This sound indicates the thermostat is operating properly. If the thermostat does not click, try the

reset operation listed below. If the thermostat does not click after being reset, contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or a service person to verify

the heating system is operating correctly.

No Cool

| 1.) System Switch not set to Cool2.) Loose connection to thermostat or system

3.) Cooling System requires service or thermostat requires replacement

| Verify thermostat and system wires are securely attached.Diagnostic: Set System Switch to Cool and lower setpoint below room temperature. Same procedures as diagnostic for “No Heat” condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling if the compressor lock-out option is selected in the installer

menu. (see INSTALLER MENU, item 50)

Heat, Cool or Fan Runs Constantly| Possible short in wiring, thermostat, heat, cool or fan system| Check each wire connection to verify they are not shorted or touching other wires. Try resetting the thermostat. If the condition persists contact your HVAC service person.
Thermostat Display & Thermometer Disagree| Thermostat display requires adjustment| Display can be adjusted +/-5°. See User Menu item04
Furnace (Air Conditioner) Cycles Too Fast or Slow (narrow or wide temperature swing)| The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate| Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently but runs for a shorter time. If you would like to increase cycle time, choose SLO for slow cycle in the Installer menu. (Reference menu items 30 & 35) If an acceptable cycle rate is not achieved, contact your HVAC service person.

“Call for Service” icon appears on displayed

| 1.) Heating system is not able to heat the space to within 10 degrees of the setpoint within 2 hours2.) Cooling system is not able to cool the space to within 10 degrees of the setpoint within 2 hours

3.) If “–” is displayed for the Room Temperature, a replacement thermostat is needed

4.) None of the buttons operate on the thermostat

| 1.) See corrective action for “No Heat”2.) See corrective action for “No Cool”

**** 3.) Replace thermostat

**** 4.) Make sure keypad lockout is not turned on (denoted by  icon)

Resetting the Thermostat or Thermostat Settings
If the thermostat has good batteries, but has a blank display or does not respond to key presses, the thermostat should be reset by removing the batteries for 2 minutes. This reset will not change the menu settings or program. If the condition persists after reinstalling the batteries, replace the thermostat.
To conveniently reset only the schedule and user settings back to factory defaults, press Menu and Backlight buttons at the same time and hold until the display goes blank and resets.
