LK 160 SmartBio Controller

The LK 160 SmartBio is an electronic differential temperature

controller for use with pellet boilers charging thermal stores.

The controller comes with 3 x 4 meter sensors, these measure the

temperature in the top and bottom of the thermal store and in the

pellet boiler itself.

When the top of the tank falls below its set temperature this

triggers a relay inside the controller to turn the pellet boiler

on. Only when the bottom sensor has reached its target temperature

will the pellet boiler turn off. The use of two sensors in the tank

make the boiler stay on for longer and also what's more important is

that the boiler stays off for longer. This stops any short cycling

and increases the efficiency and lifespan of the boiler and its

parts.
