It is a flow-compensated temperature controller, type IHPT. Simply I would say it controls domestic hot water temperature by regulating district heating flow through the heat plate exchanger. When hot water tap is opened IHPT valve opens, thermostat senses DHW temperature coming out of the heat plate exchanger and starts to control temperature.
