Round Mechanical Thermostat, Heat Only

Description

Honeywell T87K “The Round” is a world-famous, timeless classic thermostat that is a pinnacle of simplicity and reliability. This thermostat is mercury-free and designed for 2 or 3-wire heating only applications. Super easy to use – simply dial the desired temperature. No buttons or levers and no batteries to change means that this thermostat is simple to operate and is non-programmable. Note that this model is power-stealing – double-check compatibility before purchasing. Also, being a mechanical thermostat, it has a 2-3°F accuracy (compared to 1°F in digital models) which is expected.
