Somebody provided this reset procedure on this forum awhile back. Not sure it applies to your model. 11. The four button thermostat reset:
1. Turn all zones OFF.
2. Press and hold temp UP and DOWN buttons together.
3. Press and release MODE button once.
4. Release temp UP and DOWN buttons.
5. Press and release MODE button once again.
6. Thermostat light goes out indicating reset is complete.
Hope it helps, Jim
