ACOVA Thermostat Troubleshooting Manual
Practical troubleshooting guide for NOIROT, AIRELEC and ACOVA brand thermostats covering the most common failures affecting these devices—such as when the display and indicator lights flash or stop working entirely. This repair manual addresses two distinct generations of electronic boards: older designs using a capacitor and resistor as a voltage dropper without a transformer, and more recent versions equipped with a transformer. The guide walks you through typical symptoms including flashing or failing displays and indicator lights, provides precise technical specifications for replacement components, and explains the practical differences between polarized and non-polarized capacitor types. You'll find detailed voltage checks to verify proper operation and practical installation advice to help extend the lifespan of the electronic board and its components. An essential reference for anyone servicing or maintaining these thermostat systems.
