Tunstall SV21TEOU Electric Zone Valve Actuator Instruction Manual
Description
EHSVA is a self-acting actuator that is self-sufficient through energy
harvesting. Wirelessly integrate with building automation to allow for
suitable heating control on a room-by-room basis. Reduce heating costs by
heating exactly when needed.
They can be mounted on all Macon NT series valves.

Operation
The EHSVA provides itself with electrical energy through energy harvesting. The electricity is made using a thermoelectric generator (TEG), which utilizes the temperature difference between the heater and room air.
The EHSVA is an electric actuator which produces it’s own energy and is
operated over radio.
Energy generation through the Setback Effect
Integration
The EHSVA can be easily integrated into your system. The single room
regulation is carried out through the room controller.
The Battery-Powered Alternative
You can also have our efficient actuators in a battery version of this
product. This battery version is not energy self-sufficient, but has a longer
working time per battery change than the electric thermostatic valves
available.
Safety Instructions
- Operate the device only in dry indoor areas.
- Ensure that the device does not come into contact with liquids.
- Ensure that the device is not covered by objects, curtains, drapes or the like during operation, and that adequate ventilation is provided.
- Do not expose the device to heavy mechanical loads, extreme temperatures or strong vibrations.
- Only qualified personnel are allowed to open, repair or maintain the device.
- Ensure that the device is taken out of operation if safe operation is no longer possible.
Operating Instructions, Energy Harvesting Actuator
Mode of operation: The actuator generates the electrical energy for its
operation from the heat of the heating water or steam. The internal battery
stores the energy for the operation of the actuator.
Field of application: The actuator is designed for use in private and in
commercial environments.
Charging during operation may be necessary in rarely heated rooms. The device
reports this in good time via radio communication.
Assembly: The actuator can be installed directly on standard Macon valves.
Delivery state: The pin should be completely retracted when you receive
the device. If this is not the case, please use a thin pin to press the button
for 3-6 seconds (see button opening).
Normal operation
The actuator communicates about every 10 minutes via radio with the room
controller, accepts the new setpoints and controls the heating with these
values. Press the button once briefly if you require an additional
interrogation of the setpoint between the normal transmission intervals (e.g.
for quick transfer of the new setpoint after the temperature in the room has
been changed).
Status LED
The covered, red status LED provides feedback for certain functions of the
actuator:
1x blinking: Single push of the button with successful teach-in to the
remote terminal; or upon successful communication with the remote terminal
3x blinking: Single push of the button with failed teach-in to the remote
terminal; or upon failed communication with the remote terminal
Special functions
Interrupted radio connection to the room controller:
The actuator regulates to the last desired temperature transmitted.
Not enough energy:
When the energy accumulator is empty, the actuator opens the radiator valve to
50% and assumes idle state. As soon as sufficient hot water or steam flows,
the actuator restarts automatically and controls the heating as before. The
accumulator of the actuator can also be recharged via the micro-USB.
Calcification protection:
To prevent calcification, the actuator opens and closes the valve
automatically after a few weeks.
Frost protection:
At too low a temperature, the actuator opens automatically and regulates the
temperature to a value above the freezing point.
Reset:
Press and hold the button to initiate a reset. The red LED lights up after
approximately 6s. A reset has been triggered as soon as the LED goes out. You
can now release the button.
Disassembly
If you want to remove the actuator from the radiator, press and hold the
button once for 3-6 seconds. The Smart Valve moves to the installation
position. You have now 10 minutes to remove the actuator. After that time, it
automatically exits the installation position if it has been correctly taught
in at a room controller before.
Disposal Note:
As individual components of fixed installations, Tunstall products are not
subject to the Electrical and Electronic Equipment Act (ElektroG). Most of our
products contain valuable raw materials and should therefore not be disposed
of as household waste. Ensure that they are recycled properly. The locally
applicable disposal regulations must be observed.
