Product Usage Instructions:
Installation:
Follow the steps below for installing the DM10x HVAC
Controller:
- Refer to the manual for detailed installation instructions and
safety precautions. - Select an appropriate location for the controller, ensuring
proper ventilation and accessibility. - Connect the necessary power supply and wiring according to the
system requirements. - Securely mount the DM10x HVAC Controller in place.
Diagnostics:
The DM10x HVAC Controller provides diagnostic capabilities for
troubleshooting and monitoring the system. Refer to the manual for
detailed instructions on accessing and interpreting the
diagnostics.
Usage Scenarios:
DM101 Controlling a Fan Coil Unit:
The DM10x Controller can be used to control a fan coil unit
(FCU). The controller features five relays that are galvanically
decoupled, allowing independent control of each load. If the
heating and cooling valves share the same power, external wiring is
required to connect these signals to the DM10x controller. Refer to
the manual for a diagram and detailed instructions on configuring
the controller for this application.
DM102 Controlling a Fan Coil Unit with Proportional
Valves:
The DM10x Controller can also be used to control a fan coil unit
(FCU) with proportional valves. This application requires
additional configuration and setup. Refer to the manual for a
diagram and detailed instructions on configuring the controller for
this application.
DM10x Front-Side Bus as Low-Voltage I/O:
The DM10x Controller features two four-pin bus headers that can
be used as additional low-voltage input/output (I/O) ports. Each
port can be individually configured as a communication bus or as a
digital I/O. When configured as a digital I/O, each header provides
one digital input and one digital output. Refer to the manual for
instructions on configuring and utilizing these low-voltage I/O
ports.
DM10x Controlling Master Contactor Relay:
The DM10x Controller can be used to control a master contactor
relay. This application requires the use of a compatible relay,
such as the chassis-mount T9AP1D52-12 by TE Connectivity Potter
& Brumfield Relays. It is important to ensure that all local
electrical code requirements are met when deploying such a setup.
Refer to the manual for detailed instructions on configuring and
connecting the master contactor relay.

Overview
The DM10x is a high-density DIN-rail mounted controller assembly. It is designed for room automation systems and is used in several different application situations. Common applications are the control of HVAC systems, such as Fan Coil Units (FCU) or Packaged Air Conditioning (PTAC). The controller is powered with 12VDC from an external power supply. For load control, five built-in relays can directly control line-voltage loads and there is full galvanic decoupling of the low voltage side from the line-voltage side. The controller features pluggable headers for a simplified maintenance should equipment have to be exchanged during the operating phase. The DM101 is a basic controller with just the five relays while the DM102 contains an array of low-voltage digital and analog inputs and outputs to support more advanced application scenarios. For networking, the DM10x controllers can daisy chained with other controllers that are part of a load center. Further, the DM10x has a built-in Rf radio for direct communication with other room automation system components.

Applications
DM101 Controlling a Fan Coil Unit
The diagram below shows a basic configuration for controlling a fan coil unit (FCU). The five relays do not share any commons which means that each of the five loads is controlled galvanically decoupled. If for example the heating and cooling valve use the same power, then these power signals have to be wired together externally to the DM10x controller.

DM102 Controlling a Fan Coil Unit with Proportional Valves
In the diagram below, we see a more elaborate HVAC control schema that utilizes the DM102. In this sample application, three relays are allocated to drive the fan motor of a FCU. A fourth relay is used to engage a secondary heat. The primary heating and cooling valves are based on a 0-10V analog signal and driven by the analog outputs of the DM102. An additional return-air temperature sensor in the form of a 10k NTC probe is attached to provide the control algorithm with a reading of the return air temperature.

DM10x Front-Side Bus as Low-Voltage I/O
When configured correspondingly, the two four-pin bus headers can be used as additional low-voltage I/Os. Each port can be individually configured to either act as a communication bus or as a digital I/O. When configured as a digital I/O, each header features one digital input and one digital output.
The figure below shows an example how the front-side I/Os can be used. The left digital output (DO-L) is used to drive a relay with a 12VDC coil. DO-L and DO-R both feature a free-run diode to avoid damaging the output when the relay is turned off. The right digital output (DO-R) is driving directly an LED. Both outputs feature a current setting capability that run 1mA through the pushed output. This avoids that the LED will require an external current limiting resistor. The digital inputs (DI-L, DI-R) are connected to each a dry-contact input. This could be a momentary pushbutton or a toggle switch.

DM10x Controlling Master Contactor Relay
If the signals on the right-side front connector are not otherwise used, then a master contactor relay coil can be directly operated by the DM101. To enable this feature, the function needs to be engaged as part of the device configuration. The DM10x can directly drive a 12VDC coil up and has all the necessary protection circuits built in. This master relay will be under software control and typically be engaged when the room is occupied. In this case, all outlets and loads that generally are not needed when the room is not occupied can be turned off when the occupant has left the space.
As an example, the chassis-mount T9AP1D52-12 by TE Connectivity Potter & Brumfield Relays can be used for such an application. The designer of such a deployment needs to assure that all local electrical code requirements have been met.

DM10x Overcoming Rf Limitations in Sheet Metal Housings
The Rf communication with the DM10x might be negatively impacted if the device is housed in a sheet metal enclosure. It can often be observed in real deployment that some Rf capabilities still exist, such as when the AvEWB laptop is brought into proximity to the enclosure. However, the Rf signal is significantly attenuated and a reliable communication with equipment a bit further away might be questionable. Any further signal attenuation, such as if a mesh network should be formed with equipment in other rooms, is typically not achievable any longer. To overcome this condition, the DM10x controller can use a RD102.RFB (Rf Bridge). This matchbox sized device will reside outside the sheet metal enclosure and will provide nominal Rf performance to the controllers inside the enclosure. If multiple controllers reside inside the enclosure, only a single Rf bridge will be required. As the controllers inside the enclosure are daisy chained, they can share the Rf bridge resource. The diagram below shows only the key elements pertaining to the Rf bridge. There is no impact on the I/O headers of the controllers.
The image to the right shows how a number of daisy chained DM10x controllers use the RD102RFB device to provide communication capabilities when fully enclosed in a sheet metal housing. The RD102RFB is the smaller black device to the left of the Meanwell power supply
