Point type Functions
MONOGYR
room
@MGR
The point type @MGR helps to directly control one or several RCE
individual room controllers or SEZ switching units. Together with those
units, the following functions can be implemented:
– Heating/cooling.
– Heating/cooling with summer/winter changeover.
– Heating/cooling in sequence (sequence control) with summer/winter
changeover for the second sequence (heating/cooling).
– Adding the air speed as an auxiliary variable.
– Switching a potential-free relay contact.
– Acquiring the signaling contact.
MONOGYR
group
@MGG
Point type @MGG allows for carrying out the following higher tasks:
– Automatic and manual assignment of the operating modes for the
MONOGYR rooms (Comfort, Economy, Reduced).
– Default setting for corrected setpoints based on the outside
temperature.
– Calculation of the air volume of MONOGYR rooms.
– Statistical values on room occupancy, room temperatures (min.,
max., and median values), and controller outputs (min., max., and
median values).
– Switch-on optimization OSC for heating and cooling:
– Definition and registration of energy demand for MONOGYR rooms.

One master and up to nine slave controllers can be assigned to one MGRn.
No room units must be connected to the slave controllers.
The above functions can be operated via the BPS as the communications master.
Operation takes place via:
• VISOTOOL Editor
• VISONIK data and communication server DCS / VISONIK Insight.
• POP cards (personal operating process cards).
