Product Instructions Mixing Valve Actuator The Actuator is designed to provide electronic temperature control for Viega’s Mixing Valves in heating, cooling, and snow-ice melting applications. The actuator is designed to fit and modulate three way and four way mixing valves. The Actuator is operated by a 24V signal from the Viega Basic Heating Control or Advanced Snow Melt Control.

Product Instructions Mounting The Mixing Valve Actuator includes a four piece mounting kit for installation onto Viega’s old and new three and four way Mixing Valves. The installation of the actuator depends on the piping configuration and orientation of the mixing valve. The actuator position can be manually adjusted by pulling and turning the black cap. The actuator can not be mounted with the housing facing the ground.

Product Instructions Manual Operation Prior to manual operation power should be turned off to the actuator. To manually operate the actuator pull the temperature dial knob and rotate clockwise or counter clockwise depending on temperature desired. To disengage manual operation turn the temperature dial to align with valve position and push it back into actuator housing. Note: The motor actuator should not be engaged in manual operation for a prolonged period of time.
