Deep Programming Mode:
Numbering below in ** represent reference numbers in Fig 12.
Setting Code 2:
10. Programming Code 2: With unit on, lower temperature set-point to
59° F (15° C).
11. Turn the system off by pressing the <on /off button> - *14*.
12. Simultaneously press the <Snow Flake> and <Sun> buttons - *11*.
13. Now in deep programming mode, hit the <F> button twice. The
number 2 will be displayed *15* on the left along with the current
value code to the right *16*. e.g. 2 00
14. To change this value, use the <Snow Flake> or <Sun> buttons to
increase or decrease the value. For c5 confutations, use the-
following value:
• Programming at nominal temperature 59°F (15 °C) Code 2
value 00 (C1 and T1 closed in heating mode)
15. To confirm a function change, hit the <F> button once to proceed to the next category and hit the <on / off>
button to confirm.
16. Change is successful when the message “NENO” is displayed.
Setting Code 9:
1. Programming Code 9: With unit on, raise temperature set-point to 84° F (29° C).
2. Turn the system off by pressing the <on /off button> - *14*.
3. Simultaneously press the <Snow Flake> and <Sun> buttons - *11*.
4. Now in deep programming mode, hit the <F> button nine times. The number 9 will be displayed *15* on the left
along with the current value code to the right *16*. e.g. 9 03
5. To change this value, use the <Snow Flake> or <Sun> buttons to increase or decrease the value. For c5
confutations, use the following value:
• Programming at nominal temperature 84°F (29 °C) Code 9 value 03 (C2 and T1 closed in heating mode)
6. To confirm a function change, hit the <F> button once to proceed to the next category and hit the <on / off>
button to confirm.
7. Change is successful when the message “NENO” is displayed.
Setting the Proper Function:
1. To change the function mode: turn the unit on by pressing the <on / off> button.
2. Hit the <F> button until the Function category is reached. The letter F will be displayed *15* on the left along with
the current value code to the right *16*. e.g. F 04
3. To change the value, use the <Snow Flake> or <Sun> buttons to increase or decrease the value. For c5
confutations, F 04 and F05 will be the only recommended and usable selections. Refer to the descriptions
below to determine which value is correct for the end user.
• F 04 = Auto Cycle Switching with External Heat Source (AC Heat, Fuel/Water Heater, etc.) - No Reversed
Cycle Valve.
• F 05 = Heat Cycle Only with External Heat Source Alone.
4. To confirm a function change, hit the <F> button once to proceed to the next category and hit the <on / off>
button to confirm.
5. Change is successful when the message “NENO” is displayed.
