Technical design
Each type of controller has 5 applications of ventilation/ air conditioning plants preprogrammed. Some of them require extension modules.
When commissioning a plant, the relevant plant type must be entered. All associated functions, terminal assignments, settings and displays will then automatically be activated, and parameters not required will be deactivated.
In addition, each type of universal controller has 4 empty applications loaded:
1 for basic type A (ventilation controller).
1 for basic type P (primary air handling).
1 for basic type C (demand-dependent chilled water controller).
1 for basic type U (universal controller).
Using the operator unit RMZ790 or RMZ791, the controller permits:
Activation of a preprogrammed application.
Modification of a preprogrammed application.
Free configuration of applications.
Optimization of the controller settings.
For operating actions of the functions, refer to the Basic Documentation CE1P3150en.

Mounting and installation notes
Kleinspannungsseite
Netzspannungsseite
Controllers and extension modules are designed for:
– Mounting in a standard cabinet as per DIN 43 880.
– Wall mounting on an existing tophat rail (EN 50022-35x7.5).
– Wall mounting using two fixing screws.
– Flush panel mounting.
Mounting in wet or humid room not permitted. Must have proper ambient conditions
If the controller is not operated inside a control panel, use the detached operator unit
RMZ791 in place of the plug-in type operator unit RMZ790.
Disconnect the system from the power supply prior to mounting and installation the controller.
Do no remove controller from the terminal base!
If extension modules are used, they must be attached to the right side of the controller in the correct order in accordance with the internal configuration.
Extension modules are not wired to one another or the controller. Electrical connections are automatic as of insertion. If it is not possible to arrange the extension modules side by side, the first of the detached modules must be connected to the last previous module or to the controller using the RMZ780 module connector. In that case, the cumulated cable length may not exceed 10 m.
All connection terminals for protective extra low-voltage (sensors, data bus) are located in the upper half of the unit, those for mains voltage (actuators and pumps) at the bottom.
Each terminal (spring cage terminal) can only accommodate one solid wire or one stranded wire. Cables must be stripped to 7 to 8 mm to connect. To introduce the cables into the spring cage terminals and to remove them, a screw driver size 0 or 1 required. Cable strain relief can be provided with the help of the fixing facility for cable ties.
The controller mounted on a top hat rail together with modules can only be removed from the rail after the module directly attached to the controller has been removed
The controller is supplied complete with installation instructions and operating instructions
Commissioning notes
Using the operator unit RMZ790 or RMZ791, or the service tool, staff trained by
HVAC Products and having the required access rights can change the configuration and the parameters online or offline at any time.
During commissioning, the application is switched off. The outputs are in a defined
OFF state. No process and alarm signals are issued on the bus
The controller restarts automatically after completing configuration
When leaving the commissioning pages, the peripheral devices connected to the universal inputs (including the extension modules) are automatically tested and identified. An error message is generated if peripheral device is missing
The operator unit can be removed and plugged in or connected while the controller is operating
If adaptations to specific plants are required, they must be recorded and the documentation kept inside the control panel.
For the procedure to be followed when starting up the plant for the first time, refer to the installation instructions.
