LK 961 fits directly onto a mixing valve and acts as a weather compensated
heating controller. The LK 961 automatically adjusts the supply water
temperature as the outdoor temperature changes. LK 961 includes a freeze
protection feature and an adjustable minimum and maximum temperature
limiter for the supply water temperature.
LK 961 includes:

Design
LK 962 includes an electronic timer with night and day program, adjustments
for minimum and maximum supply water temperatures and a freeze protection
feature. All essential settings are adjustable at the room thermostat. LK 962
actuator fits directly onto the mixing valve and can easily be integrated into
existing heating systems. LK 962 needs no outdoor sensor. It responds to all
kinds of temperature changes in the house caused by e.g. solar heat through
windows, strong winds etc. The micro processor compensates for such changes
in temperature which a system with an outdoor sensor cannot do. LK 962 is an
advanced electronic temperature controller. Through impulses from the room
sensor, changes in room temperatures are forwarded to a micro processor which
directs the actuator to set the mixing valve in the position that corresponds to
the heat required in the building.
LK 962 includes:
