Function
Thermomatic 125 is a series of units with mixing function for heating or cooling applications. Based on our well known and reliable TV 3S mixing valves and Thermomatic actuators.
Connection
Shut off valves are to facilitate servicing. The installation position does not affect the function of the Thermomatic 125, but the lines must be connected to the correct port on the valve.
