Tech ST-431N Automatic Mixing Valve Control

A heating system consists of a number of components. For the boiler to operate efficiently, it's important to ensure the proper functioning of each mechanism. The Tech ST-431N thermostat is required for the operation of the 3- and 4-way mixing valve with the option to connect an additional pump.

General characteristics

An additional feature of the controller is its ability to operate in conjunction with valves. The ST-431N also features climate control and can easily interact with a room thermostat. One of the device's advantages is its effective return temperature and liquid boiling protection system. The ST-431N controller's key functions include:

• maintaining the operation of 3- and 4-way valves;
• pump operation control;
• the ability to fine-tune valves with the help of
