2024 New 24V Battery 1 Heat 1 Cool 7 Day Programmable Electronic HVAC Home Thermostat for Air Conditioner
Model 3205 is a 24V single stage room thermostat for apartment air conditioning, wired for 1 heat and 1 cool. It runs a full 7 day schedule from 2 x AA batteries, reads the room through an NTC sensor and displays setpoint and room temperature on a digital LCD. The load rating is 1 amp per terminal with 1.5 amp maximum across all terminals combined, which covers the contactor and fan relay loads of a typical split or packaged unit.
Key Benefits
