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.
2. 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® 1000(NC) and 1200(NC) thermostats. Be sure to use the correct column for the new thermostat.

Additional Operation Features

Compressor Protection Feature
This thermostat includes an automatic compressor protection feature to avoid potential damage to the system from short cycling. This thermostat automatically provides a 5-minute delay after turning off the cooling system output to protect the compressor. This protection is also present in the heat mode of operation on heat pump systems to protect the compressor.
NOTE:  The installer can bypass the compressor protection feature by pressing the RESET button. This will erase all user program settings, returning all settings to their default values. This should only be used during installation for testing purposes or to reset a thermostat to regain normal operation.

Low Battery Detection and Replacement
This thermostat requires two (2) new, properly installed “AA” Alkaline batteries to provide proper thermostat power when 24 volt AC power fails or is not connected to the thermostat.
When the batteries start to become too weak to provide proper operation, the thermostat will begin to display a low battery indicator.
The low battery indicator is provided to inform the user when the batteries require immediate attention. We recommend replacing the batteries as soon as the low battery indicator appears. If the batteries are not replaced after the low battery indicator first appears, the thermostat may not provide proper heating or cooling system operation.
Even if the low battery indicator does not appear, the batteries should be replaced at least once a year, or if you plan on leaving the premises for over a month.
This thermostat can be powered from 24 volts AC or battery power. To determine if 24 volt AC power is connected to the thermostat, refer to the installation and wiring diagram section. If you cannot determine how this thermostat is powered, call a professional service technician to determine the type of installation and the proper operation of your system.

Non-Volatile Memory
In the event of a power failure, the Non-Volatile Memory feature allows all settings to be recovered, eliminating the need to reset temperature and differential settings. When AC power is restored after an outage or batteries are reinserted, all settings are retrieved from memory and reinstated.

Status Indicators
HEAT: This will turn on whenever the system switch is in the HEAT mode. “HEAT” will flash when the heating system is running.

• COOL: This will turn on whenever the system switch is in the cool mode. “COOL” will flash when the cooling systems is running.
• AUX (Model 1200 and 1200NC Only): This will turn on when the auxiliary (second stage) of heating is active. The auxiliary stage of heating is usually the least economical stage of heat and typically runs when the first stage of heat cannot keep up with the temperature demand.
  NOTE:  AUX is also displayed when the system switch is in the Emergency (EMER) Mode.

Battery Replacement

Replacing the Batteries

1. Open front cover and locate the battery compartment door.
2. Gently remove the two “AA” alkaline batteries located in the battery compartment.
3. Install two new “AA” alkaline batteries into battery compartment. Make sure to match the positive (+) ends of the batteries with the positive (+) terminals located in the battery compartment.
4. Close battery compartment. The low battery indicator should not appear in the display.

Troubleshooting

• Symptom:  Thermostat does not turn on heating or cooling system.
  Potential Solution: Check to see if OFF is shown in the display. This indicates that the system is turned off at the thermostat. Move the system selector switch to HEAT or COOL position. After the compressor short cycle protection 5-minute period expires, the system should start.
  Compressor protection feature may be in effect due to compressor short cycle conditions. See Section 6.
  Heating or cooling system may be malfunctioning. Call a professional service technician immediately to verify system operation.

• Symptom:  Thermostat turns on heating instead of cooling, or cooling instead of heating.
  Potential Solution:  Check thermostat wiring to make sure the heating and cooling stages are connected to the correct terminals on the wiring block. See Section 9.

• Symptom:  Thermostat turns heating or cooling system on too often or not often enough.
  Potential Solution:  Increase or decrease temperature differential settings as appropriate to provide the desired performance level. See Section

• Symptom:  Low battery indicator is blinking in thermostat display.
  Potential Solution:  Replace batteries immediately to maintain proper system operation. See Section 7.

• Symptom:  OFF is shown in thermostat display and heating or cooling system will not start.
  Potential Solution:  This indicates that the system is turned off at the thermostat. The thermostat must be in HEAT or COOL mode of operation to control the heating or cooling system. Move the system selector switch to the HEAT or COOL position.

• Symptom:  Thermostat display is blank.
  Potential Solution:  It is possible that AC power is not present at the thermostat, and/or the batteries are drained. Check fuse, circuit breaker and thermostat wiring as appropriate to verify AC power is available. Replace batteries before reprogramming thermostat. See Section 7. If AC power is present, call a professional service technician to verify thermostat and system performance.

• Symptom:  HI is shown in the thermostat display.
  Potential Solution:  The temperature sensed by the thermostat is higher than the 99˚ F (37˚ C) upper limit of the thermostat’s display range. The display will return to normal after the sensed temperature lowers within the 40˚ to 99˚ F (4˚ to 37˚ C) display range. Turn on the cooling system or use other methods to lower the temperature accordingly.
  This condition could occur from the system being turned off during an exceptionally warm period or upon installation when the thermostat has been stored for a long period of time in a warm vehicle or location prior to being installed.

• Symptom:  NO AUX SET is shown in the thermostat display. (model 1200 and 1200NC only)
  Potential Solution:  The thermostat (model 1200 and 1200NC only) is configured for a conventional system, and the system switch is in the EM HEAT position. The unit will still function in a conventional 2 stage HEAT mode, but the display will flash NO AUX SET. Move the system switch to the HEAT position.

• Symptom:  LO is shown in the thermostat display.
  Potential Solution:  The temperature sensed by the thermostat is lower than the 40˚ F (4˚ C) lower limit of the thermostat’s display range. The display will return to normal after the sensed temperature rises within the 40˚ to 99˚ F (4˚ to 37˚ C) display range. Turn on the heating system to raise the temperature as needed for comfort within the room.
  This condition could occur from the system being turned off during a cold weather period or upon installation when the thermostat has been stored for a long period of time in a cold vehicle or location prior to being installed. The thermostat should be allowed to warm up prior to installation to allow proper heating control once installed.

• Symptom:  Cannot program a set point temperature higher than 90˚ F (32˚ C).
  Potential Solution:  This is above the normal thermostat temperature setting range of 45˚ to 90˚ F (7˚ to 32˚ C).

• Symptom:  Fan continues to run whether the system is on or off.
  Potential Solution:  Check that the fan control switch is in the AUTO position. This will allow the fan to run only when the heating or cooling system is turned on and running. Check thermostat wiring to make sure that the fan control wiring is connected to the correct terminals on the wiring block. See Section 9.

• Symptom:  The room is too warm or too cold.
  Potential Solution:  See Section 5. Review current set point and change as necessary.

• Symptom:  HEAT or COOL is flashing, but the system is not running.
  Potential Solution:  The thermostat is telling the heating or cooling system to run, but the system is not responding. You may need to call your local heating and air conditioning contractor.
