Johnson Controls T25A-16 2-Stage Line-Voltage Thermostat 40°F-90°F

The Johnson Controls T25A-16 is a two-stage line voltage thermostat that is used to control temperature in different commercial and industrial environments. It has a simple mechanical design of the control panel with individual knobs for the desired temperature of heating and cooling. The two-stage operation indicates that the HVAC system can perform in two stages and this is better than one-stage thermostats. The first stage of the thermostat is to turn on the low capacity stage of your heating or cooling system to get to the set temperature. The first stage brings the system near the setpoint and the second stage then adds the extra heat or cool to take it to the setpoint.
