NOIROT Thermostat Troubleshooting Manual
Practical troubleshooting guide for NOIROT, AIRELEC and ACOVA brand thermostats. This service manual addresses the most common failures affecting these heating control devices, such as display and indicator light malfunctions—whether they flash unexpectedly, dim, or stop working entirely. The guide covers two distinct generations of electronic boards: older designs that use a capacitor and resistor network as a voltage dropper without a transformer, and more recent boards equipped with a dedicated transformer. You'll find detailed symptom descriptions, precise technical specifications for replacement components, and clear explanations of polarized versus non-polarized capacitor types with practical installation guidance. Voltage check procedures are included to help verify correct circuit operation, along with maintenance advice designed to extend the working life of the electronic board and its components.
