INSTALLATION AND REFERENCE RUN

Mount the device on the M30x1,5 valve body, turn dial to the left or right to the end position to short press the button. The MVA executes a reference run and enters normal operation.

 

During the first 10 minutes, the MVA sends in a ten-seconds radio communication interval. When unmounted, the MVA returns to the assembly position. After 1 hour, the push buttons lock automatically. Unlocking: Pull-off the dial cover and press both buttons simultaneously for 10 seconds.

ADDITIONAL THINGS TO KNOW

  • Connection nut M30 x 1.5; adapters are available for many other valve types https://micropelt.atlassian.net/wiki/spaces/MH/pages/16252981

  • Energy storage LiFePo4 320 mAh

  • Operating modes: Valve position % or Setpoint temperature °C

  • Freeze protection < 6°C (Valve side sensor)

  • The iTRV becomes active according to the telegram specification and asks for the room controller on the control position or setpoint temperature. The controller then adjusts the valve according to the following response of the room controller.

  • Unmounting: To remove the iTRV, turn the dial to left or right until its end position and hold for at least 5 seconds to 1x green LED, wait for motor to stop, then loosen knurled nut and remove iTRV.
