3.Use up and down buttons to move between OF and ON on large display. Factory default is OF.

4.Press SET TIME/TEMP button again to flash upper small display for selection of another option, or press END to exit configuration mode.

Option 17ÐEnable Non-Programmable Operation

This option converts the programmable Thermidistat Control to a non-programmable control for those users who do not want programmability. The clock is retained, but the days of the week and the daily schedules have been eliminated, making it operate as if HOLD were permanently ON. Some of the buttons (used in programming only and now not needed) are redefined to simplify the non-programmable operation. To match these redefined but- tons, a new keypad label, included with the Thermidistat, must be placed over the original keypad label. Fig. 2 shows both the original keypad label and the non-programmable keypad label. When this option is selected, the new keypad label must be applied over (or in place of) the original. Because these adhesive-backed keypad labels are not designed to be removed, this conversion should be considered permanent. Once the change to non- programmable operation is done, a procedure is not provided to easily change it back. Should this change be needed, it is best to trade the Thermidistat for one which has not been converted.

Both programmable and non-programmable versions of the Ho- meowner's Manual are available. Be sure to leave only the correct version of the Homeowner's Manual with the homeowner.

Once it has been determined that a particular installation is to be made non-programmable, the only changes required are:

·Attach non-programmable keypad label over original program- mable one.

·Attach non-programmable start-up sticker instructions to back of door.

·Set Configuration Option No. 17 to ON.

·Leave non-programmable homeowner's manual with home- owner.

To attach the provided non-programmable keypad label, carefully peel off its backing and apply it over the original keypad label. PLEASE HEED: Once the new keypad label makes contact, it will stick firmly in place and adjustments cannot be made. CARE- FULLY locate an edge of the keypad label, making sure its position and orientation are correct. Then, from the attached edge, smooth the rest of the keypad label over the original. Make sure the new keypad label does not interfere with the motion of the buttons which it surrounds.

TO SELECT:

1.Enter configuration mode if not already there. See Step 4 "To Enter Configuration Mode." Use up and down buttons to make small (now flashing) display indicate 17.

2.Press SET TIME/TEMP button once to flash large display.

3.Use up and down buttons to move between ON and OF on large display. Factory default is OF.

4.Press SET TIME/TEMP button again to flash upper small display for selection of another option, or press END to exit configuration mode.

REDEFINITION OF BUTTONS

Fig. 2 shows the original (programmable) button labels on the left and the redefined (non-programmable) buttons on the right. In the figure, the buttons are numbered for easy reference. They are not numbered on the actual product. Six of the buttons (numbers 1 through 5 and 9) have been redefined.

Button 3 originally alternated between time, cool set point, and heat set point with each press. Now, button 1 selects the cool set point, button 2 selects the heat set point, and button 3 selects time, now used only to set the clock. Note that the days of the week are gone.

Button 5 used to alternate between humidify and dehumidify. Now button 4 selects dehumidify and button 5 selects humidify.

Button 9 now loses the HOLD label, making it END only. This button is only used to END the humidity screen and the configu- ration mode.

These changes both simplify operation for the homeowner and find use for the buttons which are no longer needed when programma- bility is removed.

Step 5ÐSystem Start-Up and Checkout

The Thermidistat Control is designed with a built-in installer test capability. It allows easy operation of equipment without delays or set point adjustments to force heating or cooling.

To enable installer test mode, move DIP switch No. 4 to ON position. To access this switch, open case as described in Step 2. Use the corner of a small screwdriver to slide switch No. 4 to ON position.

While in installer setup mode, clock will display "InSt," FAN button will control fan, and MODE button will control heating and cooling.

TO TEST FAN:

Fan button switches FAN icon between AUTO and ON. While ON is displayed, G output will be on, turning fan on. Allow up to 10 sec after button is pressed for fan to turn on and off. On some fan coils, fan continues to operate for 90 sec after G signal is removed.
