TAC Forta M800 Manual

M800 is an electro-mechanical actuator for the control of
two-way and three-way plug valves in:
• domestic hot water systems
• heating systems
• air handling systems
M800 is either controlled by an increase/decrease signal
or by a modulating 2–10 V control signal. Modulating
control makes for a faster positioning of the actuator.
The electronic circuitry of the actuator ensures that the
running time is the same, regardless of the stroke of the
valve in question.
It is easy to mount and connect the actuator. It can be
mounted directly onto TAC's control valves, without any
mounting kit.
The working range of the actuator is adjusted
automatically depending on the stroke of the valve. The
electronic circuitry of the actuator then takes care of the
adjustment of the valve end positions.
The actuator is supplied by 24 V AC. It can provide
16 V DC voltage supply for older TAC controllers.
