16. SYSTEM RESET
a. Turn the ON/OFF switch to OFF position.
b. Simultaneously depress and hold the MODE and ZONE
push-buttons while turning the ON/OFF switch to ON.
FF should appear in the LCD display until the MODE
and ZONE push-buttons are released.
c. When a dip switch is turned on or off after initial configu
ration, a system reset will need to be done before the
Comfort Control CenterTM will recognize the updated selection. Try this. This is for the five button thermostat. Did you check the dip switches to be sure the proper ones are turned on? I need to know which stat you have 4 or 5 button. I have trouble shooting for both.
If you notice reset needs to take place after a dip switch is turned on or off. The dip switches are on the circuit board. You need to drop the lower cover. the dip switches will read in this order #1 heat strip/ #2 zone2/#3zone3/ #4 zone4/#5 furnace/#6 differential/#7stag/#8 gen start. Check this out and be careful. Turn off the stat to change dip switches. On will be toward the description. If you don't have remote start gen set the dip should not be on. If you dont have a Zone 3 the dip should not be on, etc.
Any questions feel free to post back

Make sure that you are not running the unit on low fan speed. In the warmer months of the year, this will often cause the unit to freeze up due to the lack of air flow through the evaporator. If you are running on high and it is still freezing, then you possibly have a freon leak in the system. The brisk airs are notorious for the capillary tubes in the upper unit rubbing together and developing a small leak. The problem is usually where the two small tubes enter the evaporator housing. Remove the cover and pull the two small lines apart, damage should be apparent if there is any. If not, you may have developed a leak elsewhere and need to have someone check out the system.
Hope this helps,

clicking sound could be thermal overload on the compressor. If the compressor has gone out the unit will not cool the clicking sound is possibly the compressor trying to reset but if the compressor has "gone to ground" (winding burnt out) you will need to have the compressor replaced. Good luck on your repairs hope this helped some
