TITAN - Energy Saving Controls

Controller Overview:

Brief:

The Titan Controller with Diffusions Energy Saving software strategy is designed to be a cost effective
multi-purpose digital control unit fulfilling the requirements for either Electric or Hot Water door
curtain and heating unit types.
The control system consists of a Titan FCU-402 controller mounted within the heating unit, and a room
/ wall mounted RDU-4 user interface / display module; connected to the controller via an RJ11 cable.

Features:

RDU-4 LCD room / wall mounted user interface / display module.
Simple RJ11 plug connection between unit controller and room display module.
Soft-touch button control on RDU-4 for winter / summer changeover, and fan speed selections.
BACnet - RS485 cable connection between multiple units and BMS system.
RS485 network communications, BACnet protocol, for full BMS monitoring and control integration.
User adjustable engineering setting; including Supply air temperature and Room / Return air
temperature.
On/off Volt free contact input for time clock or BMS control.
Display of fan speed, off coil temperature, and % heating output; and Fault conditions.

Adjustable Off Coil set-point, factory default setting of 40°C.
Return Air / Room Thermostat input to reduce or turn off heating when room temperature set-point
reached.
Return air temperature measurement in place of room stat for greater flexibility
High precision supply and return air temperature sensors.

Three fan speed settings, plus off, with silent fan speed switching.
BMS controllable of fan speeds.

Summer/Winter changeover settings.
Option for outside air temperature for fully automatic Summer / Winter changeover control.

On/off input for occupancy sensed control; with adjustable run on time, default 15 minutes.

Direct PID control of valve actuators for water fed systems.
PID control of electric heating elements via external solid-state relays.
Master/slave control of heating output and fan speeds achieved with RS485 twin twisted pair cable
between units / controllers.

TITAN - Energy Saving Controls

Controller Operation Sequence:

Brief:

On / Off and Fan speed function are manually selected via the RDU-4 user interface / display module.
Time clock switching or BMS connection can control these functions remotely.

Summer / Winter operating modes are manually switched selected via the RDU-4 user interface /
display module.
Outside temperature sensor or BMS connection can control this function remotely.

Off coil and Return Air sensors are used to control the temperature of the air leaving the supply grill to
maintain the Off Coil set-point value; for Summer or Winter mode.
However when the Return Air temperature reaches that set-point this turns the heating off; unless the
Set-back temperature has been adjusted, when this feature reduces the Off Coil temperature by the
Set-back value rather than turn the heating off completely.

Control Point Settings:

Feature Factory Setting User Adjustable

Summer Off Coil Temperature 18.0°C Yes

Winter Off Coil Temperature 40.0°C Yes

Summer Return Air / Room Temperature 16.0°C Yes

Winter Return Air / Room Temperature 25.0°C Yes

Off Coil set-back 0.0°C Yes

PIR Sensor – Delay Off 15 mins Yes

Outside Temperature Summer / Winter Change over
OT Summer Set-Point Temperature 20.0°C Yes

OT Winter Set-Point Temperature 15.0°C Yes

The above diagram shows a typical 3-wire daisy chain configuration. For all BACnet standard wiring variants please consult ASHRAE wiring standards.

BACnet Network Configuration:

50.0

Based on the standards for RS485 networks a BACnet MS/TP network layer allows for only a daisy­chained network configuration, consisting of a single cable routed between controllers. Star and
Ring network topologies are not supported.

The network electrically supports a maximum of 127 nodes, however BUS network size capability is
determined by factors such as network traffic and BMS capabilities and we recommend maximum
network size of 32 or 64 devices.

To comply with the EIA-485 standard, the maximum number of nodes per segment shall be 32 and
any additional nodes will require the use of repeaters. If only Titan controllers are on the MS/TP
network, the number of controllers may be increased but this will depend on the network traffic,
the baud rate being used and the length/route of the cable.

A termination resistor of 120 ohms should be connected at each of the end devices, when a
network is connected to a Router or BMS this becomes one of the end devices. Please check with
the Router/BMS manufacturer if the 120 ohms end of line resistor is fitted internally.

TITAN - Energy Saving Controls

BACnet Technical Reference:

60.0 - Network Configuration

MS/TP allows for only a daisy-chained network configuration, consisting of a single cable routed between controllers.
Star and Ring network topologies are not supported.

The network supports a maximum of 254 nodes; addresses 0 to 127 are valid for both master and slave nodes and
addresses 128 to 254 are valid only for slave nodes.

To comply with the EIA-485 standard, the maximum number of nodes per segment shall be 32 and any additional nodes
will require the use of repeaters. If only Titan controllers are on the MS/TP network, the number of controllers may be
increased to 127 dependent on wiring length as specified below.

A termination resistance of 120 ohms shall be connected at each of the two ends of the segment medium.

60.1 - Cable Specifications

The cable used in an MS/TP EIA-485 network should conform to the following specifications:

Wire Size: 22-24 AWG
Cable Type: Twisted-pair, copper wire, tinned and a ground wire which must be connected to all devices on the
485 network.
Shield: Foil or braided
Nominal Impedance: 100 – 130 
Capacitance: < 100 pF/m distributed capacitance between conductors
< 200 pF/m distributed capacitance between conductors and shield
Max segment length: 1200 meters (4000 feet)

The cable shield must be connected to Earth ground at the network router end only.

The recommended cable is Belden 3106A.

60.2 - Commissioning Settings

The BACnet commissioning settings can be accessed on the graphical RDU or programming tool by simultaneously
pressing all four buttons. The left buttons can be used to scroll through the menu selections and the right buttons to
change settings. To navigate and access the engineers settings please see supporting documentation.

The following settings need to be commissioned before connection to the MS/TP network:

60.3 - BACnet Device Object Identifier: This setting allows the entry of a unique internet work wide BACnet Device
Object Identifier. With a default setting of 0000000, the device will operate on the local MS/TP network but will not
dynamically bind and initiate I_Am messages. A valid Device Object ID in the range 1 to 4194302 can be entered and
this will set the Device Object Name to “FCU4 DevObjectID”.

60.4 - MAC Address: This setting corresponds to a unique MAC address on the local MS/TP network and can be in the
range 1 to 127.

60.5 - Baud Rate: This setting corresponds to the MS/TP network Baud Rate and should match all other devices on the
same local network. Options are 9600, 19200, 38400 and 76800.
