Thermostat selection guide

The table below represents compatibility of various Lux thermostats with different application types.

H = Heat; C = Cool.

All Lux thermostats that are battery powered or dual powered (system and/or battery) come with batteries pre-installed.

Programmable vs. Non-Programmable vs. Mechanical

When choosing the thermostat type, consider the flexibility of programming options you want to have.

Lux programmable thermostats are available in several options, such as 5+2 days, 5+1+1 days and 7 days, where:

5+2 days: (1) Separate programming schedule for weekdays and (1) schedule for weekends;

5+1+1 days: (1) Separate programming schedule for weekdays, (1) schedule for Saturday and (1) schedule for Sunday;

7 days: Separate programming schedule for every day of the week;

A clear advantage of programmable thermostats is the alibility to schedule operating time in a manner that will allow for more energy savings.

Digital thermostats, on the other hand, cannot be programmed and are common for applications that call for a constant room temperature throughout the whole day. One of the advantages of digital thermostats is compatiblity with a large variety of applications, as displayed in the table above.

Mechanical thermostats are another example of low cost solution in applications that require a constant temperature, however, unlike digital models, can only be used for 1 stage heat systems only.
