AquaHot Themostat Problem

The themostat that controls the two zone temperature settings seem to randomly reset itself to one 'furnace' setting; no zones.  If I cycle the off-on switch on bottom of unit, it will revert back to two zones. Anyone know why this might be happening?
Thanks, Mike

Hi Mike,

You might try doing the "reset procedure":

If you have a 4 button Dometic thermostat try this reset procedure:

a. Turn the ON/OFF switch to ON. The display light with data should come on.
b. Depress mode to activate display light.
c. Depress the bottom two buttons (up & down) together.
d. While still holding the two buttons add the third from the bottom (mode).
e. Release the third (mode) button.
f. Release the bottom two (up & down) together.
g. Depress the mode button. The display light should be off. If not, repeat steps a through g.
 The control should return to the default setting of 68deg F for heating mode and 72 deg F for cooling mode.
