Installation

Replacing Existing Thermostat

Most thermostats have three parts:

• The cover, which may snap or hinge over the existing thermostat.

• The electronics or body, which controls the existing system.

• The sub-base, where the wires attach through the wall to the existing system.

1. Always turn off power to the air conditioning or heating system prior to removing existing thermostat.

Carefully remove the cover and electronics body from the old thermostat sub-base. Depending on the brand, these parts may pull off or need to be unscrewed. The old sub-base should remain wired and on the wall until steps 4 and 5.

3. Label every old wire with the letter of the connection to which the wire is attached. Example letters are R, M, Y etc. Depending on the brand of the old thermostat, your letters may be different.

4. After labeling the old wires, loosen each connection and remove them from old sub-base. Secure the wires to prevent them from slipping into the hole in the wall.

5. Remove the old sub-base from the wall, again being careful that the wires do not slip into the hole in the wall.

6. Use the chart below to determine the new thermostat connections. As an example, if the old thermostat had a G connection, it goes to G on the new thermostat. Note the chart includes information for Braeburn 1200(NC) thermostats. Be sure to use the correct column for the new thermostat.

Installing New Thermostat

NOTE: If installing this thermostat in a new installation, locate the thermostat 4 to 5 feet above the ﬂoor in accordance with applicable building codes. Install the thermostat in a location that provides good airﬂow characteristics and avoid areas behind doors, near corners, air vents, direct sunlight or heat generating devices. Installation in these areas could impact thermostat performance. Wiring must conform to all building codes and ordinances as required by local and national code authorities having jurisdiction.

1. Turn off power to the air conditioning or heating system prior to installing thermostat.

2. Place system switch on front of thermostat to OFF position.

3. Place fan control switch on front of thermostat to AUTO position.

4. Remove front of thermostat body from sub-base by pressing release latch.

5. Place the thermostat sub-base against wall in the desired thermostat location.

Guide thermostat wires through hole in sub-base. Continue to hold against wall.

Mark placement of mounting holes as appropriate and drill using a 3/16" drill bit.

8. Gently tap supplied plastic anchors into the holes in the wall.

9. Place the thermostat sub-base against the wall in the desired location,

making sure the mounting holes are aligned and the thermostat wires are inserted into the opening in sub-base.

10. Fasten sub-base to wall using supplied screws.

11. Connect wires to quick wiring terminal block using the new terminal

designations. See section 7.

12. Make sure all of the wire connections are secure and not touching any other terminal to prevent electrical shorts and potential damage to the thermostat.

13. Turn the front thermostat body over, exposing the rear view of the circuit board.

14. Locate the internal ˚F /˚ C switch on the circuit board. Using your ﬁngers, ﬂip the switch toward the preferred temperature ˚F / ˚C scale.

15. Locate the internal fan option switch, HG (Gas) / HE (Elec) on the circuit board. This switch controls the heating system fan delay. Select gas for gas or oil ﬁred systems. This will allow the furnace to run for a few seconds before initiating the fan. Select electric for systems with electric furnace elements that require the fan to come on immediately. Using your ﬁngers, ﬂip the switch toward HG (Gas) or HE (Elec).

NOTE: For heat pump systems, the fan option switch should be set according to the second stage heating system type.

16. Locate the internal NORM / HP switch on the circuit board. This switch conﬁgures the thermostat for conventional (NORM) heating and cooling systems or heat pump (HP) systems. Using your ﬁngers, gently ﬂip the switch toward NORM or HP.

17. Attach front body of thermostat to sub-base of thermostat, being careful to align the terminal pins on the front body with the terminal block on the sub-base.

Installation

18. Open front thermostat door and open battery compartment door.

19. Install two new "AA" alkaline batteries. Locate the positive (+) ends of the

batteries and match them with the positive (+) terminals located in the battery compartment. Close battery compartment.

20. Restore system power so you can test installation.

NOTE: If the thermostat was powered (batteries installed) prior to accomplishing steps 14 through 16, you will need to reset the thermostat to register thermostat switch conﬁgurations prior to programming any user settings. Gently press the RESET button on the front of the thermostat using a paperclip or a small pencil tip.

NOTE – MODEL 1200, 1200NC: If the thermostat is conﬁgured for a conventional system and the system switch is in the EMER position, the unit will still function in a conventional 2 stage HEAT mode, but the display will ﬂash NO AUX SET.

Testing Your New Thermostat

WARNI N G !

• Do not short (or jumper) across terminals on the gas valve or at the heating or

cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.

• Do not select COOL mode if the outside temperature is below 50˚ F (10˚ C). This could damage the controlled cooling system and cause personal injury.

• This thermostat includes an automatic compressor protection feature to

avoid potential damage to the cooling system from short cycling. This

thermostat automatically provides a 5-minute delay after turning off the

cooling or heating system output to protect the compressor.

NOTE: Test your thermostat prior to programming any user settings. Pressing

the RESET button will erase any user entries previously programmed and return them to their default values.

1. Place the system switch in the HEAT position.
