Anleitung Zusammenfassung
These controls incorporate system fault analysis for quick gas flow shut-off, coupled with automatic ignition retry upon sensing a fault correction. Signals interpreted during continual surveillance of the thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shut-off during normal operation. TRANE APPLICATION - Installer MUST read page 3 “Mounting and Wiring” PRECAUTIONS Installation should be done by a qualified heating and air conditioning contractor or licensed electrician. If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or licensed electrician. Do not exceed the specification ratings. All wiring must conform to local and national electrical codes and ordinances. This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction. Following installation or replacement, follow manufacturer’s recommended installation/service instructions to ensure proper operation. WARNING Failure to comply with the following warnings could result in personal injury or property damage. FIRE HAZARD • Do not exceed the specified voltage. • Protect the control from direct contact with water (dripping, spraying, rain, etc.). • If the control has been in direct contact with water, replace the control. • Label all wires before disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. • Route and secure wiring away from flame. SHOCK HAZARD • Disconnect electric power before servicing . • Ensure proper earth grounding of appliance. • Ensure proper connection of line neutral and line hot wires. EXPLOSION HAZARD • Shut off main gas to appliance until installation is complete. CAUTION Do not short out terminals on gas valve or primary control. Short or incorrect wiring may damage the thermostat.
