Setup, Compatibility & Care
To install, ensure the power supply to the heating system is isolated at the mains. Remove the old timer unit from the back-plate, verify the wiring configuration matches the terminal diagram provided with the PF1CT, and align the unit pins with the existing back-plate terminals.
Compatibility is guaranteed with most UK standard heating back-plates. For care, keep the unit clear of excessive dust and moisture. If the screen becomes dirty, wipe it gently with a dry, lint-free cloth. Do not use chemical cleaners or solvents as these may damage the plastic housing or the digital display.
