15. SAT 3C/D/F INSTALLATION
SAT 3C/D/F Benefits and Features
SAT 3C/D/F CONTROLLER VERSES SAT 2C/D CONTROLLER BENEFITS
THE SAT 3C/D/F CONTROLLER HAS A SMALLER MECHANICAL FOOT PRINT THAN THE OLD SAT 2C/D CONTROLLER
THE SAT 3C/D/F CONTROLLER USES THE SAME WIRING AS THE SAT 2C/D CONTROLLER
THE SAT 3C/D CONTROLLER USES THE SAME TUC AND RTU COMMUNICATION PROTOCOL AS THE SAT 2C/D CONTROLLER -
SO IN THEORY, A TUC OR RTU CHANGE OUT IS NOT REQUIRED WHEN CHANGING A SAT 2C/D CONTROLLER TO A SAT 3C/D
CONTROLLER. BUT MUCH BETTER CONTROL IS GENERALLY POSSIBLE WITH THE NEWER WCC III BASED TUC/RTU SOFTWARE.
THE SAT 3C/D/F CONTROLLER USES THE SAME SATELLITE DATA FILES AS THE SAT 2C/D CONTROLLER
THE SAT 3C/D/F CONTROLLER PROGRAM UPDATES ARE AVAILABLE VIA A "FLASH" PROGRAMMING OR A DOWNLOADED
UPDATE. THE SAT 2C/D CONTROLLER SOFTWARE UPDATES HAD TO BE CHANGED OUT WITH A EPROM. THE SAT 3C/D/F
CONTROLLER CAN BE CHANGED BY REMOTELY DOWNLOADING THE SOFTWARE OR BY "FLASHING" A NEW PROGRAM
INTO THE SAT 3 D CONTROLLER'S MEMORY. A FLASH C/ /F PROGRAMMING TOOL IS AVAILABLE TO THE CONTRACTOR.
BOTH USB AND PARALLEL PORT VERSIONS OF THE FLASH PROGRAMMING TOOL ARE AVAILABLE.
ADDED SAT 3C/D/F CONTROLLER FEATURES
A TUC2R (WM part # 320) would have 2 control relays on board. (With two different types of optional expansion boards there could be either OE
A TUC5R (WM part # OE330-21) would have 5 control relays on board. (No expansion possible) (-21 is on metal back plate)
A TUC5R+ (WM part # OE331-21)would have 5 control relays on board. (With a series of different types of expansion boards)
A TUC5RX (WM part # OE332-23) would have 5 control relays on board. (With a series of different types of expansion boards)
A VAVZ-II Box Controller (WM part # OE324-23) is an all in one plastic housing for VAV Zoning control that can be used with the optional
WM OE217 LCD display Temperature sensor. An optional I C Relay expansion board is available for this controller, but it is different
2
than the O 321 and OE322. (-23 is in plastic E enclosure)
The most common TUC2R application is what is called VAVBOX control, with a tri-state actuator used to modulate a damper for the temperature
Zone. This VAVBOX software can be configured for pressure dependent operation or pressure independent operation with the addition of an optional
pressure sensor. An optional expansion board can be added for control of Series or Parallel Fan and stages of electric Box Heat. There is another
optional expansion board that can be added instead for control of series or parallel fan, stages of electric box heat, and an analog output for an analog

New to the WCC III is the VAVZ-II Box Controller. SAT 3D version is WM Software # SS5014, and the current software is version 3.10.
When ordering a WattMaster controller, please specify the controller’s "OE" part number followed by the "SS" software part number.
WM part # OE321 is a 4 Relay expansion board for the TUC2R controller and is software dependent. (
5001 only) SS
WM part # OE322 is a 3 Relay and one analog output for HW valve control, is an expansion board for the TUC2R controller, and is software
There was "custom" TUC2R and TUC5R software that was written in 1980s and 1990s, and you would have to read the EPROM label of the boards
to get replacement controllers if needed. Call WattMaster for further details.
THE SAT 3C/D/F CONTROLLER HAS AN ADDITIONAL FOUR LEDS THAT DISPLAY THE STATUS OF THE RECEIVE AND TRANSMIT
FOR THE SAT LOOP RS-485 AND TUC LOOP RS-485 COMMUNICATIONS. IT DOES THIS FOR BOTH THE SAT III COMMUNICATIONS
LOOP AND THE TUC PORT. IN ADDITION, THERE IS A SEPARATE LOCAL SET LED, AND THREE STATUS LEDS.
THE SAT 2C/D CONTROLLER ONLY HAD AN LED THAT WAS A COMBINATION - POWER, COMMUNICATIONS, AND LOCAL SET
INDICATOR FOR THE SATELLITE MANCHESTER COMMUNICATIONS LOOP.
SAT III - COMMUNICATIONS
THE SAT 3C/D/F CONTROLLER NOW USES RS-485 COMMUNICATIONS. THE SAT 2C/D CONTROLLER USED A TRANSFORMER
COUPLED MANCHESTER ENCODED PROTOCOL THAT WAS DIFFICULT TO TROUBLESHOOT. THE BEST BENEFIT OF HAVING
RS-485 COMMUNICATIONS IS THAT IT CAN BE TROUBLESHOT WITH A DIGITAL VOLTMETER.
