CATEGORY: UNDERFLOOR HEATING PARTS
Actuator for R298 or R298N mixing valves, with integrated regulator
Description
K282X002 is an actuator that works both as motor and regulator, to control the delivery temperature with three way mixing valve.
The actuator can be used on three way valves: it controls fixed delivery temperature both heating and cooling, in “stand-alone” functioning.
