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

20. 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.

21. Restore system power so you can test installation.

NOTE: If batteries were 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 paper clip or a small pencil tip.

NOTE–MODEL 3200: If the thermostat 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 EM HEAT SET.

Testing Your New Thermostat

WARNING!

• 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 may 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.

2. Press the button on the keypad until the set point temperature setting is a

minimum of 3 degrees higher than the current room temperature. The heating system should start within several seconds. The fan may not turn on immediately due to the heating system built-in fan delay.

3. Place the system switch in the OFF position. The heating system should stop within several seconds on conventional heating or cooling systems. On heat pump systems, you must wait 5 minutes for the automatic compressor short cycle protection period to expire, or press the RESET button to bypass this feature for initial testing purposes. Pressing the RESET button will erase any user program settings.

4. Place the system switch in the COOL position.

5. Press the button on the keypad until the set point temperature is a minimum

of 3 degrees lower than the current room temperature.

Setting Temperature Differentials

The default settings for the ﬁrst and second stage differentials are compatible with most systems and applications. This is normally set at time of installation and usually does not require any modiﬁcation under normal operating conditions. If you feel that your system is turning on too often, simply follow the instructions below.

NOTE: The temperature differential settings are the same for both the heating and cooling systems.

Setting First Stage Differential

The default setting is 0.5˚ F (0.25˚ C). The room temperature must change .5˚ F (0.25˚ C) from the set point temperature before the thermostat will initiate the system in heating or cooling.

1. In normal operating mode, press and hold the and buttons at the same time for 3 seconds. LCD display will show "SET D1 X˚", where "X" equals the ˚F / ˚C differential setting. This is the current ﬁrst stage differential setting.

2. Press the or buttons to set the ﬁrst stage differential to your desired setting of .5˚, 1˚, or 2˚ F (.25––displayed as .3˚, .5˚ or 1˚ C).
