II.INSTALL THERMOSTAT

WARNING: 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.

1.Turn off all power to unit.

2.If an existing thermostat is being replaced:

a.Remove existing thermostat from the wall.

b.Disconnect wires from existing thermostat. Do not allow wires to fall back into the wall. As each wire is disconnected, record wire color and terminal connection.

c.Discard or recycle old thermostat.

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

3.Remove the thermostat cover from wall plate (mount- ing base) to expose mounting holes. See Fig. 1. With the thermostat facing forward, press the back plate on the left hand side top corner to release the two prongs holding on the cover. Pull off the cover when the prongs have been disengaged.

4.Route thermostat wires through large hole in mount- ing base. Remove outer sheath from wires for added ¯exibility. Standard solid or multi-conductor thermo- stat wire should be used from the thermostat to the unit. Size and length considerations are as fol- lows: for a maximum distance from unit of 36 ft, use 22 AWG (American Wire Gage) wire; for a maxi- mum distance from unit of 100 ft, use 18 AWG wire.

Fig. 1 Ð Thermostat Mounting

5.Level mounting base against wall and mark wall through the 2 mounting holes in base.

6.Drill two 3¤16-in. mounting holes in wall where marked.

WARNING: Be careful not to drill into wiring in wall. Electrical shock could result.

7.Secure mounting base to wall with 2 screws and an- chors provided. Ensure all wires exit through hole in mounting base.

8.Adjust wire length and routing to allow proper closure of the thermostat. Strip each wire at the end no more than 1¤4-in. to prevent adjacent wires from shorting to- gether. Match and connect wires to terminals on the thermostat. See Fig. 2-4 and Table 1.

CAUTION: Improper wiring or installation may cause damage to the thermostat. Check to ensure wiring is correct before proceeding with installation of unit.

9.Push excess wiring into wall. Seal hole in wall to pre- vent drafts.

10.Re-attach thermostat cover to back plate by aligning the top two prongs of the back plate in the vertical groove of the top cover and then snapping the cover onto the back plate.

11.Turn on power to unit. The thermostat will receive power from the unit. The thermostat will be powered by 24 v, nominal (18 to 30 vac). Terminals R (+ 24 v), W1/O/B (®rst stage heat or reversing valve), Y1 (®rst stage cool- ing), and G (fan relay) will always be connected. Some applications will use C (common), Y2 (second stage cool- ing), or W2 (second stage heating).

III.SET CLOCK

The Set Clock button allows the user to change the time and day displayed on the thermostat. Press the Set Clock button. The current time will blink on and off. Press the UP ARROW and DOWN ARROW buttons until the correct time is shown. Hold down the buttons to quickly move through the time dis- play. Press and hold the Fan button while pressing the UP or DOWN ARROW buttons to scroll through by hours. The AM and PM annunciators will automatically change. To ensure the schedules are properly followed, make sure that AM or PM is correct for the time chosen. When the correct time is shown, press the Mode button to modify the day of the week. The current day will blink on and off. Press the UP ARROW and DOWN ARROW buttons until the correct day is shown. Press the Set Clock button again to exit the Set Time mode.

IV. HEAT PUMP CONFIGURATION

To con®gure the thermostat for heat pump operation, Ad- vanced Setup Steps 3 (Heat Pump Operation) and 4 (Revers- ing Valve Polarity) must be con®gured correctly. See the Con®gure Advanced Setup section for information on con®g- uring these options.

NOTE: Some large commercial rooftop heat pump units (542J) must be con®gured with Advanced Setup Step 3 (Heat Pump Operation) set to OFF. Refer to the base unit instructions for more information.

V. CONFIGURE ADVANCED SETUP

To enter into the advanced setup screens of the thermostat, press the Mode and Program buttons at the same time. The Advanced Setup Step number is shown in the top right cor- ner of the thermostat screen. Use the Mode button to ad- vance through the steps. There are 17 Advanced Setup Steps. See Table 2. Press the Program button at any time to exit the Advanced Setup mode.

NOTE: Advanced Setup Steps 1 and 2 are con®gured with the Set Clock button, and are not accessed through the ad- vanced setup screens.
