The Heat‑Timer MPC is a microprocessor‑based outdoor reset controller used to cycle steam boiler or motorized valve operation in single‑pipe and two‑pipe steam heating systems. Common failures include loss of communication with the boiler/valve due to bad wiring or insulation, failure of the internal temperature sensor or relay contacts, and firmware corruption that can cause the unit to lock up or display “reset” errors. Initial diagnostics should verify power supply voltage and continuity on input/output terminals, inspect the thermostat probe for corrosion or disconnection, and review any error codes displayed on the panel’s LCD or LED indicator.[oss-gpt-20b] |
