Optional FX10 Control Random Start

Main FX 10 Board

The optional FX10 control provides unparalleled capability in several areas including performance monitoring, zoning, humidity, energy management, and service diagnosis, and then communicates it all thru standard DDC protocols like N2, Lon and BACnet (MS/TP @ 19,200 Baud rate).

The most unique feature is integrating the FX10 into the Envision series as both the heat pump and DDC controller providing both a cost advantage and providing features not typically found on WLHP controls. This integration allows heat pump monitoring sensors, status and service diagnosis faults to be communicated thru the DDC direct to the building automation system (BAS), giving building supervisors detailed and accurate information on every piece of equipment without removing an access panel.

FX10 Advanced Control Overview

The Johnson Controls FX10 board is specifically designed for commercial heat pumps and provides control of the entire unit as well as input ports for Open N2, LonTalk, BACnet (MS/TP @ 19,200 Baud rate) communication protocols as well as an input port for a user interface. The user interface is an accessory item that can be used to aid in diagnostics and unit setup. A 16-pin low voltage terminal board provides terminals for common field connections. The FX10 Control provides:

•Operational sequencing

•High and low-pressure switch monitoring

•General lockout

•Water Coil Low Temperature (Freeze Sensing)

•Condensate overflow sensing

•Lockout mode control

•Emergency shutdown mode

•Random start and short cycle protection

Short Cycle Protection

Allows a minimum compressor “off” time of four minutes and a minimum “on” time of two minutes.

A delay of 1 to 120 seconds is generated after each power- up to prevent simultaneous startup of all units within a building after the release from an unoccupied cycle or power loss.

Emergency Shutdown

A field-applied dry contact can be used to place the con- trol into emergency shutdown mode. During this mode, all outputs on the board are disabled.

Water Coil Low Temperature (Freeze Sensing) Limit

Field selectable for 15° or 30°F (-9° or -1°C)

Installation Options

•Standalone controlled by standard room thermostat

•Standalone with a Zone Temperature Sensor (must have user interface to change set points beyond the allowed +/- 5°F)

•Integrated into BAS by adding communication module

Accessory Outputs

Quantity 2. One cycled with fan, other with compressor.

User Interface

4 x 20 backlit LCD.

Optional Plug-in Communication Modules - (compatible with standard BAS protocols)

•Open N2

•LonTalk

•BACnet (MS/TP @ 19,200 Baud rate)

Display

Requires DLI Card/Kit. Up to 2 displays, either 1 local and

1 remote, or 2 remote. (A 2-display configuration requires identical displays.) Local display can be up to 3 meters from the controller, power supply, and data communica- tion. Remote display can be up to 300 meters from the controller. Remote display must be independently powered with data communication done via 3 pole shielded cable.
