The ST-19 Regulator is designed for regulating the circulation pump of the central heating system. The desired temperature setting is made via a potentiometer.

The regulator has the capability to activate the pump when the temperature reaches the preset value and to deactivate it when the temperature falls by 2°C below this. This function helps save energy and extends the life of the pump.

Additionally, the ST-19 regulator features the ANTYSTOP function, which prevents the standstill of the circulating pump over time. The pump activates every approximately 10 days for 1 minute.
