Differential Temperature Controllers | LK 160 SmartBio LK 160 SmartBio Technical Data Voltage 230 VAC ± 10%, 50 Hz Power consumption 3.5 VA Relay output Max. 240 VAC, 4 A Triac outputs 230 VAC ± 10%, 1 A, 200 VA High-efficiency pump Analog output 0 -10 V, max. 10 mA PWM output 100 Hz - 10 kHz Sensors PT 1000 Display TFT backlit colour display 47 x 35 mm Protection type IP 20 Protection class II 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 backlit 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 • Output for high efficiency pump • 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 88 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 temperature 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. In order to prevent self-circulation in both directions a check valve with double acting flow should be mounted between the circulating pumps - see under 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 difference between the tanks LK 160 Smart- Bio 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 controls the charge pump to the domestic hot water tank, the zone valve of the main tank and the circulator in the heating loop.
