TO TEST HEATING:
Press MODE button until HEAT icon under it turns on. Press up button until HEAT set point (LOWER right 2 digit display with HEAT now flashing under it) is 2° or 3° (not more) above room temperature. This will create a Heat Stage 1 demand. A small triangle to the left of this HEAT icon will flash or come on continually. Flashing means the equipment is going to turn on but is presently being held off by a system timer. (See Operational Information for timer descriptions.) Defeat timer by pressing INCREASE TEMPERATURE button (up and FAN buttons to- gether). This will make the triangle stay on and turn on Heat Stage
1.To turn off, reduce heating set point below room temperature. The heating and the triangle will turn off within a few seconds.
If the system has multiple heat stages, it will start on Heat Stage 1 and proceed to Heat Stage 2, 15 minutes later due to a staging timer which requires 15 minutes between successive stages. The INCREASE TEMPERATURE button (up and FAN buttons) cannot be used to defeat this timer. If set point is raised more than 5° above room temperature, the staging timer is defeated and the thermostat will call for higher stages within 5 sec. Use this method if there are only 2 stages of heat. If more than 2 stages of heat are available, do not use this method because once the demand exceeds 5°, the thermostat may jump to the highest stage. With more than 2 stages available, let the timer advance one stage every 15 minutes.
TO TEST EMERGENCY HEAT (heat pump systems only):
To test, press MODE button until EHEAT icon turns on. This will allow operation of auxiliary heat only. Raising set point above room temperature will turn on the first stage of auxiliary heating (W/W1). Raising set point more than 5° above room temperature will advance to full heat, if it is available (O/W2 or Y1/W2 will come onÐsee Table 2). Reducing set point below room tempera- ture will turn all heat off.
→VI. FINAL SETTINGS
1.Assuming the system is to be left in operation after the installation is complete, use MODE button to select be- tween HEAT, COOL, EHEAT, or AUTO to provide the desired operation of heating, cooling, or both.
2.The default set points and programmed schedule conform to the Energy Star requirements of the U.S. Department of Energy for both heating and cooling. These provide energy saving temperature settings.
3.Turn on HOLD if fixed set points are to be used. If the programmed schedule is to be used, make sure the HOLD icon is off.
4.For further information on temperature selection and pro- gramming, refer to Homeowner's Manual.
5.If AUTO mode is to be used, be sure both heat and cool set points are properly adjusted.
6.The FAN button may be used to select between AUTO (fan on only with equipment) and FAN (fan on continuously) fan modes.
→VII. CHECKLIST
1.Put away tools and instruments, and clean up debris.
2.Review Homeowner's Guide with owner.
3.Leave literature packet with owner.
4.Fill out and return survey card.
