Leveling Thermostat

Leveling is for appearance only and will not affect thermostat operation.

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 handing 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 hazard. Do not short out terminals on primary control to test. Short or incorrect wiring will burn out 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.

UNIT DOES NOT USE BATTERIES MPAC 1 Jumper Wire

WIRING (cont)

Instructions: To convert the system from PTHP to PTAC, change menu item #20 from default HP to AC. Additionally, if you are using this thermostat on a Hotpoint PTAC (non-heat pump), you will need to cut the jumper wire located on the back of the thermostat.

Note: Menu item #32 will not be displayed in AC mode.

1.) O/B Terminal Switch

The O/B switch on this thermostat is factory set to the B position. This will accommodate heat pump applications, which require the changeover relay to be energized in Heat. If the heat pump being installed requires an O terminal to energize the changeover relay in Cool, the O/B switch must be moved to the O position.

INSTALLER MENU

To access the INSTALLER'S MENU, set the system switch to the OFF position and then press and hold the temperature ▲ and ▼ buttons for 3 seconds. The display will show item 20 in the table. Use the temperature ▲ and ▼ buttons by pressing them simultaneously to navigate through menu items. Press ▲ or ▼ to change a menu setting. To exit the Installer's Menu at any time, move the system switch to Heat or Cool.

TEST EQUIPMENT

Turn on power to the system.

Fan Operation

1.) Move fan switch to Low position. The blower should begin to operate at low speed.
2.) Move fan switch to Auto Low position. The blower should stop immediately.
3.) Move fan switch to High position. The blower should begin to operate at high speed.
4.) Move fan switch to Auto High position. The blower should stop immediately.

Heating System

1.) Move System Switch to Heat position.
2.) Press ▲ to adjust thermostat setting to 1° above room temperature. 1st stage heat should begin to operate.
3.) If 2nd stage resistance heat is being utilized, press ▲ to adjust the thermostat 3^ above room temperature. Resistance heat should begin to operate.
4.) Press ▼ to adjust the thermostat to 1° below the room temperature. The heating system should stop operating.

Cooling System

1.) Move System Switch to Cool position.
2.) Press ▼ to adjust thermostat setting 1° below room temperature. The blower should come on immediately, 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 thermostat setting to 1° above room temperature. The cooling system should stop operating.

Note: The default position for the compressor lockout is OFF in the INSTALLER menu, item 50. When compressor lockout is turned ON Starting Soon will be visible on the display. 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.

THERMOSTAT OVERVIEW

Before you begin using your thermostat, you should be familiar with its features, display and the location/operation of the thermostat buttons and switches.

TROUBLESHOOTING

Symptom Possible Cause Corrective Action
No Heat/ No Cool/ No Fan (common problem)	1.) Blown fuse or tripped circuit breaker2.) HVAC unit unpowered3.) HVAC unit not set for remote thermostat control4.) Loose connection to thermostat or system	1.) Replace fuse or reset breaker2.) Restore power to HVAC unit3.) Enable wall thermostat control on HVAC unit4.) Tighten Connections
No Heat/ No First Stage Heat	1.) System Switch not set to Heat2.) Loose connection to thermostat or system3.) Heating System requires service or thermostat requires replacement4.) Misconfiguration between menu item 20 and jumper wire.	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. Make sure that menu item 20 and the jumper wire match.
No Cool 1.) System	System Switch not set to Cool2.) Loose connection to thermostat or system3.) 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 item 04
Furnace (Air Conditioner) Cycles Too Fast or Slow (narrow or wide temperature swing) / No First Stage Heat	1.) The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate2.) Misconfiguration between menu item 20 and jumper wire.	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 hours3.) If “--” is displayed for the Room Temperature, a replacement thermostat is needed4.) None of the buttons operate on the thermostat5.) If “Call for Service” is flashing, compressor self diagnostic is detecting an issue with the outdoor unit	1.) See corrective action for “No Heat”2.) See corrective action for “No Cool”3.) Replace thermostat4.) Check for stuck buttons5.) Contact a service person to verify the equipment is operating correctly

Resetting the Thermostat or Thermostat Settings

To conveniently reset only the user settings back to factory defaults, press ▲ and ▼ buttons while moving the system switch from OFF to HEAT at the same time and hold until the display goes blank and resets.
