Phason FHC-1D Fan And Heater Control
 |
The Phason FHC‑1D is a variable‑speed fan and heater interlock controller that automatically adjusts fan speed to maintain setpoint temperature while shutting the heater off when the target is reached. Common failures on this class of controllers include blown input power fuses, tripped heater interlocks due to faulty relay contacts, and degraded thermistor or sensor wiring leading to incorrect temperature readings. Begin by verifying 24 V DC supply continuity and inspecting for visible burn marks; check the heater interlock relay coil voltage and contact integrity; then review any diagnostic LEDs or error codes displayed on the unit’s panel.[oss-gpt-20b] |
