Does the Alarm.com Smart Thermostat support multistage systems?
Yes, the Alarm.com Smart Thermostat is compatible with up to three stages of heating and two stages of cooling.
Does the Smart Thermostat support systems with multiple zones?
Yes, the Smart Thermostat supports systems with more than one zone. Each zone can be controlled by its own Smart Thermostat. The Smart Thermostat is compatible with other Z-Wave thermostats; however, your system will work best and most efficiently if all thermostats in the house are replaced with Smart Thermostats.
Can the Smart Thermostat control variable-speed HVAC systems?
The Smart Thermostat can control many variable-speed HVAC systems which use standard 24 volt wiring (for example, with R, G, Y, W, C wiring).
Can the Smart Thermostat control my home’s humidifier or dehumidifier?
The Smart Thermostat will be able to control either a humidifier or dehumidifier using the Z terminal. This feature is still in development and will be made available to you in the future by a firmware update.
My system has an external air baffle for fresh air. Can the Smart Thermostat work with my system?
The Smart Thermostat works with HVAC systems that have an external air baffle, where the central HVAC system programming controls the baffle. Some systems rely on the thermostat itself (not the central HVAC system) to control the baffle. The Smart Thermostat will be able to support these systems using the Z terminal. This feature will be made available in the future by a firmware update.
What can the Z terminal on the Smart Thermostat be used to control?
The Z terminal of the Smart Thermostat can currently control a third heating stage. Soon it will also be able to control a third cooling stage, humidifier, dehumidifier, external baffle/fresh air exchange, or a zone control wire. These, and other additional functions, will be made available in the future by firmware updates.
What is the expected battery life of the Smart Thermostat?
With typical use, the Smart Thermostat will last well over one year when running on battery power alone. The battery can be expected to last even longer if the Smart Thermostat is powered through the C-wire. In this case, the batteries will only be used when the power goes out.
