Reduce your expenses for heating and electricity with this control unit for circulation pumps.
This electronic control unit switches your circulation pump in the warm water circuit on and off. The water temperature will be measured at pre-selected time intervals und the pump will be switched on when necessary. The two sensors compare the temperature on the forward and return flow pipes.
When the difference in temperature reaches a value preset by the factory, the control unit will switch the pump on automatically.
When the difference in temperature has been balanced or when the maximum operation time has been reached, the unit will switch the pump off.
