LK 160 SmartBio® is an electronic differential temperature

controller with several preset hydraulic systems for energy

efficiency in heating systems with storage tanks. The chosen

hydraulic system and operation status is shown on the back-

lit colour display. Controls and settings are easily carried out

using the rotating knob and the esc-button. LK 160 SmartBio®

can handle high efficiency pumps.

LK 160 SmartBio® can also activate an immersion heater or

burner if the temperature in the primary tank falls below the

selected value. The additional heat has a sophisticated delay

function that further adds to the efficiency of the system.

FEATURES

• Several hydraulic systems

• Two outputs for circulating pumps

• Pump exercise

• Floating relay output

• Sensor balancing

• Adjustable delay function for additional heat

• Graphic, multilingual colour display with time and date

• User-friendly menu system

• SD card slot for data logging (micro SD)

• Speed control possible for two circulation pumps via PWM signal

HYDRAULIC SYSTEM 1.

Hydralic system 1 is intended for storage tank systems with a

primary and secondary tank. LK 160 SmartBio® controls the

two circulating pumps between the tanks. When the primary

tank is fully charged the charge pump starts at the chosen tem-

perature to fill the secondary tank. When the temperature in the

primary tank falls, the recharging pump starts and transfers

energy back to the primary tank.

HYDRAULSYSTEM 1.1

In order to prevent self-circulation in both directions LK 970

ThermoBac DB double acting check valve should be mounted

between the circulating pumps - see under spare parts and

accessories.

HYDRAULIC SYSTEM 1.2

The LK 824 ThermoVar® is a thermic valve with double acting

check valve function which ensures a high return temperature

to the solid fuel boiler, thus increasing the efficiency of the

system – see spare parts and accessories.

HYDRAULIC SYSTEM 2

Hydraulic system 2 is intended for storage tank systems in

which heating water and domestic hot water are taken from a

secondary tank. Heat is to be transferred from the main tank

to the secondary tank. By measuring the temperature differ-

ence between the tanks LK 160 SmartBio® controls the charge

pump.

HYDRAULIC SYSTEM 3

Hydraulic system 3 is intended for the charging of a storage

tank with a pellet, oil or gas fired burner. By measuring the

temperatures in the tank and boiler LK 160 SmartBio® controls

the burner and charge pump.

HYDRAULIC SYSTEM 4

Hydraulic system 4 is intended for storage tank systems with

domestic hot water tanks. This system gives priority to the heat

in the upper part of the main tank. This enables a fast transfer

of heat to the domestic hot water tank. LK 160 SmartBio® con-

trols the charge pump to the domestic hot water tank, the zone

valve of the main tank and the circulator in the heating loop.
