Amana-Goodman OT18-60A Thermostat

The Amana-Goodman OT18-60A is a critical outdoor thermostat for heat pump applications, functioning as the direct OEM replacement for legacy part numbers B13708-67, B1370867, and B1370867S. This field-installed accessory utilizes a Single-Pole Double-Throw (SPDT) switch to provide precise control over auxiliary heat lockouts or compressor staging based on ambient temperatures. With an adjustable temperature range of 0°F to 45°F, it prevents inefficient heat pump operation during extreme cold and ensures the secondary heat source engages only when necessary. Built to strict Goodman Amana OEM specifications, it maintains system balance and prevents unnecessary equipment cycling. For technicians servicing Amana heat pump systems, this unit offers a drop-in solution for restoring accurate sensing and control. Its heavy-duty construction is designed to withstand harsh outdoor environments while providing the reliable switching required for complex HVAC control circuits.

• Universal Compatibility: Direct replacement for B13708-67, ensuring exact electrical specifications and mounting footprints for Goodman and Amana units.
• Precise Control: The SPDT switch configuration allows for flexible wiring options to manage auxiliary heat kits or staging.
• System Protection: Minimizes compressor strain by managing operation thresholds within a 0 to 45 degree temperature range.
• Fast Installation: Engineered for quick integration into existing control panels, reducing billable time in the field.
• Reliable Calibration: Maintains setpoint accuracy over time, reducing callbacks for staging or lockout issues.

What is the primary function of the OT18-60A in a heat pump system?
It serves as an ambient sensor that locks out the supplemental electric heat when the outdoor temperature is high enough for the heat pump to operate efficiently, or locks out the compressor when it is too cold for efficient operation.

Can this thermostat be used in non-Amana/Goodman systems?
While designed as an OEM replacement for Goodman and Amana, it is a standard outdoor thermostat for heat pumps and can be applied to other systems requiring an SPDT switch with a 0-45°F range, though physical mounting may vary.

Does this unit include the mounting bracket?
It is typically supplied as the thermostat assembly; technicians should verify if existing mounting hardware from the B13708-67 can be reused or if additional field fabrication is required.
