Fixed value controller MFR3
Check the controller and its packaging carefully. If you see visible damage to the
controller, do not use it. Installing a damaged product can be life-threatening.
When adjusting the controller, pay attention to the correct opening direction of the valve.
Wrong turning direction can lead to high or low temperatures in the system and
consequently damage to the system.
When adjusting the controller, make sure you set the minimum and maximum value of
requested temperatures correctly. Incorrectly selected limit values for setting the
requested temperature lead to a wrong setup of requested temperature and,
consequently, undesirable operation and/or damage to the system and user.
The fixed value controller is designed to control a mixer. Any other use is not intended.
The controller may only be installed and operated in:
-Dry, non-explosive environment.
-Enclosed rooms.
-Rooms with a temperature between 0 °C and +55 °C.
Every project with controller must have independent system protection for cases of too
low or too high temperatures. The controller does not perform protection functions for
cases of too high or too low temperatures in the system. High or low temperatures in the
system can cause damage to the system and user.
