LK 150 SmartSol is an electronic differential temperature con-

troller for solar heating systems. The controller has, depending

on model, 20 or 24 preset hydraulic systems for different solar

heating systems. The chosen hydraulic system and operating

status is shown on the backlit colour display. Controls and

settings are easily carried out using the rotating knob and the

esc-button. LK 150 SmartSol can handle high efficiency pumps.
