Detailed Information

Description

LK SmartComfort is an electronic controller that has an automatic choice of direction to adapt to the direction of the mixing valve. LED-indicators show if the controller is opening or closing the valve. The supply temperature can be limited with a minimum and a maximum value. LED-indicators show if the controller is opening or closing the valve. Adjustments are easily made with the push buttons marked “+” and “- “. The selected value will be shown on the LED-display.

LK SmartComfort is easy to install onto new as well as existing mixing valves. Mounting kits for installation onto mixing valves of other brands are available - see separate page.

The plug-in adapter provides quick and easy do-it-yourself installation. In case of a power outage the controller will keep its settings and the actuator will stop in its current position. By disengaging the controller, the mixing valve can be manually operated.

LK 100 CT - CONSTANT TEMPERATURE CONTROLLER
LK 100 SmartComfort CT is an electronic temperature controller designed to keep the supply temperature in underfloor heating systems or the return temperature to solid fuel boilers at a constant level. The flow temperature is adjustable between 5 - 99 °C.

LK 110 - WEATHER COMPENSATED TEMPERATURE CONTROLLER
LK 110 SmartComfort is an electronic weather compensated temperature controller for hydronic radiator and underfloor heating systems. By measuring the supply and outdoor temperatures LK 110 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required in the building at any given time. The supply temperature can be limited with a minimum and a maximum value. The current supply and outdoor temperatures can be read on the controller display.

LK 120 - INDOOR TEMPERATURE CONTROLLER
LK 120 SmartComfort is an electronic indoor temperature controller for hydronic radiator and underfloor heating systems. By measuring the supply and indoor temperatures LK 120 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required in the building at any given time. The supply temperature can be limited with a minimum and a maximum value.

LK 120 SmartComfort is delivered with a room temperature unit allowing easy setting of the desired indoor temperature.

LK 130 - WEATHER COMPENSATED INDOOR TEMPERATURE CONTROLLER
LK 130 SmartComfort is an electronic, weather compensated,indoor temperature controller for hydronic radiator and underfloor heating systems. By measuring the supply, outdoor and indoor temperatures LK 130 SmartComfort regulates the mixing valve to provide the system with the exact amount of heat required in the building at any given time. The supply temperature can be limited with a minimum and a maximum value.
LK 130 SmartComfort is delivered with a room temperature unit allowing easy setting of the desired indoor temperature.

LK ROOM TEMPERATURE UNIT
The room temperature unit is available in two versions; with fixed cable SmartComfort RT or wireless receiver SmartComfort RTW.

The room temperature unit is equipped with a connection port for external control, such as via a GSM modem, making it possible to activate a preset temperature change via mobile phone.

For further energy saving and increased comfort there are nine preset programs with scheduled temperature changes. You can
also create your own programs. Additional functions such as holiday and timer settings are available. The current outdoor temperature can be read on the room temperature unit.

After a temperature setback the room temperature unit applies a booster function which briefly increases the supply temperature in order to quickly reach the desired room temperature.
Should the room temperature unit sense a sudden change in temperature, such as when airing a room, the unit disregards this change for the following half hour.

PUMP CONTROL - SMARTCOMFORT PC
For further energy saving a pump control, SmartComfort PC, can easily be connected to the controller - see under Accessories.
SmartComfort PC stops the circulating pump when no heat is required and exercises pump every two days, thus eliminating the risk of pump stalling after an intermission.

Questions & Answers

Is it possible to remove the shunt action on an LK SmartComfort?

Yes, by holding down the menu button and minus button for about 5 seconds, shunt action is turned off. To activate pump action, hold down the menu button and the plus button for about 5 seconds

Is it possible to upgrade LK 110 to LK 130 by purchasing and adding the indoor temperature controller? Or do I need to purchase the whole LK 130 set?

Yes it is possible to just add an indoor controller to your LK 110, and your SmartComfort will then have become a LK 130 instead.

What is the running time of a SmartComfort?

All our SmartComfort units rotate 90 degrees in 17 seconds.
