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.
