This is from the service manual:

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

Hope this helps

My 1990 Penguin unit has a leak. Can it be fixed?


Leaks can be repaired, some quite easily and others while difficult to find - and get to - prove somewhat more difficult.

The problem with 'leaks' is sometimes they are 'high pressure leaks' which are some of the more difficult ones to find.

So... the answer to your question is yes - but.

I would try and get a very experienced Service Tech to fix the leak, and one who will stand behind his work.

good luck!

Penguin model 610012-001a/c compressor won't start


I would check to make sure that the control is sending the "cool" signal to the control unit. LO on the room temp display usually means that the fan speed is set to low. Is LO and Auto showing on the display at the same time. Try resetting the thermostat first. Hold down the Mode and Zone buttons with the tstat off. While holding them down, turn the tstat back on and hold the buttons down until FF appears on the screen. Release the buttons and try the AC.
If this does not work, on the control board is a freeze control switch plug (blue usually). Try unplugging this unit and insert a small jumper wire. If the Compressor comes on and runs then you have a bad freeze control switch. If not, then you should replace the control board.

Hope this helps,

Jeff
