System Setup / Operation
Initial System Configuration
New MicroZone installations require a one-time system configuration procedure before use. In this mode
you can change whether the unit is connected a heat lamp or a heat mat.
Changing System Configuration / Displaying Software Revision
1. On the MC110A Controller, press and hold the SELECT key for
approximately 8 seconds (“H L” will be displayed above the SELECT key).
2. Press the UP
or DOWN
buttons to select between “HL” for heat lamps
and “HP” for heating pad (mats).
Troubleshooting
Common problems include incorrect wiring, tripped circuit breakers, burned out heat lamps or mats,
damaged power cords, etc. Internal diagnostics of the unit can detect other problems as follows:
Flashing “888” displayed
– The MC110A needs to be returned to the factory for repair.
Flashing AUTO indicator
– Communications between the Controller MC110A and the Modulator
have failed.
The communications wiring may have been damaged or become disconnected.
Intermittent AUTO Indicator
– The power modulator has detected a short circuit. When this
happens the power modulator will immediately turn off the output power, and after a 5 second
delay, slowly re-apply power. If the short circuit condition remains, the output power is turned off
and the cycle repeats until the condition is corrected. This feature protects the MicroZone modules
from a catastrophic failure.
When infrared lamps are initially plugged in, or supply circuit
breaker turned on, the high surge current may cause this error code to be momentarily
displayed.
Resetting to Factory Default Settings
To restore your MicroZone to its factory default settings, turn off power to the MC110A controller. While
holding the SELECT key on the controller, reapply power to the system. The default settings will be
restored.
