Self-healing thermostat heat pump reversing valve setting

A controller for a heat pump system, the controller comprising:

• one or more processors and non-transitory computer readable memory, the one or more processors operable to execute instructions stored on the memory, whereby the controller is configured to:
• determine a starting temperature for a space;
• configure a thermostat with a set point, wherein the set point is at least a set amount of degrees from the starting temperature;
• set a timer, wherein the timer is set to a time based on a difference between the starting temperature and the set point;
• turn the heat pump system on in either a heating mode or a cooling mode, comprising:
• turning the heat pump system on in a heating mode when the set point is warmer than the starting temperature;
• and
• turning the heat pump system on in a cooling mode when the set point is cooler than the starting temperature;
• determine a position for a reversing valve of the heat pump system based on an O/B setting, wherein the O/B setting indicates to configure the reversing valve in a first position that causes refrigerant to flow in a first direction when in the heating mode and in a second position that causes the refrigerant to flow in a second, opposite direction when in the cooling mode;
• determine if the timer has expired;
• determine whether to maintain or reverse the O/B setting in response to determining that the timer has expired, wherein:
• in response to determining that the heat pump system performs heating while in the heating mode or performs cooling while in the cooling mode, the O/B setting is maintained;
• and
• in response to determining that the heat pump system performs cooling while in the heating mode or performs heating while in the cooling mode,
• the O/B setting is reversed such that the O/B setting indicates to configure the reversing valve in the first position when in the cooling mode and in the second position when in the heating mode.

A non-transitory computer readable memory comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• determine a starting temperature for a space;
• configure a thermostat with a set point, wherein the set point is at least a set amount of degrees from the starting temperature;
• set a timer, wherein the timer is set to a time based on a difference between the starting temperature and the set point;
• turn a heat pump system on in either a heating mode or a cooling mode, comprising:
• turning the heat pump system on in a heating mode when the set point is warmer than the starting temperature;
• and
• turning the heat pump system on in a cooling mode when the set point is cooler than the starting temperature;
• determine a position for a reversing valve of the heat pump system based on an O/B setting, wherein the O/B setting indicates to configure the reversing valve in a first position that causes refrigerant to flow in a first direction when in the heating mode and in a second position that causes the refrigerant to flow in a second, opposite direction when in the cooling mode;
• determine if the timer has expired;
• determine whether to maintain or reverse the O/B setting in response to determining the timer has expired, wherein:
• in response to determining that the heat pump system performs heating while in the heating mode or perforins cooling while in the cooling mode, the O/B setting is maintained;
• and
• in response to determining that the heat pump system performs cooling while in the heating mode or performs heating while in the cooling mode,
• the O/B setting is reversed such that the O/B setting indicates to configure the reversing valve in the first position when in the cooling mode and in the second position when in the heating mode.
