logical device inputs.
Control functions
• Sequence controller for 3 heating sequences (reverse acting) and 2 cooling
sequences (direct acting), can be used as a controller providing P, PI or PID mode, or
as a differential controller
• Controller can be configured as a room / supply air temperature cascade controller
with limitation of the supply air temperature
• Each sequence can be assigned modulating control (modulating output, step switch,
mixed air damper, heat recovery equipment) and a pump. Up to 3 sequences can act
on the same analog control (e.g. priority cooling / dehumidification)
• General limitation function (minimum / maximum with PI mode per sequence
controller, either as absolute limitation (e.g. for the supply air temperature or supply
air humidity), or as relative temperature limitation (e.g. maximum limitation of the
room / supply air temperature differential). Limitation acts on all sequences.
Minimum limitation for switched on cooling (example: cooling with direct expansion
cooler battery) can be set to a lower setpoint
• Sequence limitation function with PI mode per sequence controller, can be defined as
minimum or maximum limitation. Limitation acts on a single sequence
(e.g. heat recovery anti-icing protection or maximum limitation of the air heating coil’s
return temperature)
• Lock individual sequences by outside air temperature
• Messages about deviations of setpoint / actual value per sequence controller

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.

Engineering notes
• AC 24 V voltage required to power the controller. It must meet requirements for
SELV / PELV (safety extra low-voltage)
• The transformers used must be safety isolating transformers featuring double
insulation to EN 60 742 or EN 61 558-2-6; they must be suited for 100 % duty
• Fuses, switches, wiring and earthing must be in compliance with local regulations
• Sensor wires should not be run parallel to mains carrying wires that power fans,
actuators, pumps, etc.
• It is recommended to use the standard applications provided. Specific plant situations
may require certain adaptations
• Total max. 4 extension modules per RMU7..B can be connected.

Mounting and installation notes
3144Z03
Low voltage side
Mains voltage side
• 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 50 022-35x7.5).
– Wall mounting using two fixing screws.
– Flush panel mounting.
• Not permitted in wet or damp spaces. The permissible environmental conditions must
be observed
• 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
• The controller insert may not be removed 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
• The extension modules require no wiring between themselves or to the controller; the
electrical connections are made automatically when attaching the modules. 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 the commissioning process, the application is deactivated and the outputs are
in a defined off state. This means that no process and alarm signals will then be
delivered to the bus
• On completion of the configuration, the controller automatically makes a new start
• When leaving the commissioning pages, the peripheral devices connected to the
universal inputs (including the extension modules) are automatically tested and
identified. If a peripheral device is missing, a fault status message will be delivered
• 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

The housing may only be cleaned with a dry towel.
Repair
The universal controller cannot be repaired on site.
Disposal
The universal controller is subject to Directive 2002/96/EG (WEEE, Waste of Electrical
and Electronic Equipment).
"The device is considered electronics device for disposal in terms of European Directive
