The Lux Products HP2110 Smart Temp Programmable Heat Pump Thermostat is a good choice for people who have heat pumps. It costs about $55. The Lux Products HP2110 is especially designed to regulate heat pumps. It is a thermostat that can efficiently manage both stages of a heat pump so the equipment performs at its best and doesn't become damaged. The swing control on the thermostat is also designed to work with heat pumps with auxiliary or emergency heat.

The thermostat is a 5-1-1 device. That means it has 3 program slots to set up - weekdays, Saturday and Sunday. For each program slot there are 4 periods of heating/cooling to set up. If you keep regular working hours during the week then this heat pump thermostat is powerful enough to prevent waste and thus to significantly reduce heating and cooling costs.

The Lux Products HP2110 also has temporary hold and vacation mode to allow the user to suspend programmed settings if he or she is feeling a bit hot or cold or is going on a vacation. There is also a program lock to stop children altering the programs.

Further functions include a filter change warning and a battery change warning. Although the Lux Products HP2110 is a batteries only device it doesn't drain batteries quickly.

The Lux Products HP2110 Smart Temp has a digital diaplay with a back light. It comes with Energy Star recommended default settings to guide the user when setting up his or her programs. This is a recommended thermostat for people with heat pumps.
