This diagram shows the following system:
Heat exchanger
without
bypass damper. One storage tank and a 0-10 V regulated circulator pump.
The S8 temperature sensor must be positioned in the heat exchanger inlet.
The S3 temperature sensor must be mounted on the forward flow pipe immediately after the heat exchanger.
The S1 temperature sensor must be mounted in the storage tank.
Important:
An STL thermostat which turns off the burner must be mounted on the forward flow pipe. The forward flow
temperature must not exceed 100 °C.
