Control

Thermostats can help you control a number of different home heating and cooling features—from temperature to air conditioning. Additionally, some thermostats operate on time schedules or can be controlled remotely via a mobile device, which offers even greater control.

Scale & Upgradability

As your needs change, so can your comfort requirements, which is why it's so important to choose a thermostat that can scale to meet your needs over time.

To further help, many Honeywell Home T-Series thermostats are mounted on a Universal Wall Plate that allows you to change models by simply 'popping' one in place of the other.
