The 75F Central Control Unit (CCU) is the local interface and access point for the entire 75F System. In other words the CCU is the gateway for the entire 75F system. With the help of cloud computing and wireless sensors, the CCU optimizes the efficiency of existing building equipment while keeping occupants comfortable, healthy, and productive.

Mounting the Control Mote (CM)

It's provided stiffener platelevel 5’ from the floor. When using drywall anchors, drill a 5/16” hole and insert the provided anchors. Screw the CM into place on the stiffener plate using the provided #6-3/8" into the predrilled holes.

Mounting the 75F Tablet

Be sure the power and volume buttons are facing upward. Two slots on the bottom of the tablet match two tabs on the CM plastics. Align the tabs to the slots, tilt and push back on the tablet until it clicks into place. If power is supplied to the CM and the tablet is powered on, you will see a USB icon in the upper left status bar of the tablet. The blue outline of a cloud signifies that data is being transmitted. See troubleshooting for more.




Skip to 6:13 for wiring

Connect Power and Thermostat Wires on the CM. Connect the power and common wires to the two terminals on the left side of the opening. Terminals for Cool, Fan, and Heat are located along the bottom of the opening. Each block has three terminals. From left to right, these are Power (internally connected – generally not used), Stage 1, and Stage 2. Connect the thermostat wires to their respective terminals.

Connect the Wall Sensor using the provided white harness. Connect one end of the gray RTS cable to the port on the right side of the opening and connect the other to the back of the Wall Sensor

Installer Options


Pairing Start Address:Drop-down menu specifying the start address for components paired to this CCU. You need not change this option. This is a unique identifier that is assigned to the modules in increasing order from this value (e.g. 9003, 9 is the channel the mesh network will communicate on, 003 is the unique identifier assigned for that device on channel 9)

Note:Pairing addresses range from 1000 to 10900, and the System integrator should know the RF frequencies permissible in the country where the installation is done, so that he could set the pairing start address accordingly.

Use Outside Temperature Lockout:enabling this allows the user to prevent the use of either Cooling or Heating modes based on the Outdoor Temperature.

Temperature Limits:You can use this section to set the user limits for both heating and cooling, and also set the building limits. 

  • Select the right arrow to continue.

Security:You can use this screen to set up passwords to access Settings and/ or Setup. This can be accessed and changed later.

Floor Plan and Configuration:You can use this screen to setup floors, rooms, and pair modules.


System Settings: Change settings operational system settings. 


Conditioning Mode: Set the mode of the system. “Auto” will allow the system to decide to heat or cool.

Use DX for Overnight Dehumidification: When humidity is high mechanical cooling will run during unoccupied hours to reduce the indoor humidity level


Compensate for Humidity: selecting this option will control the space temperature based on the total enthalpy of the air instead of just the dry-bulb temperature. For example, in very humid situations, the system will cool the space below the setpoint. This will make it so it “feels like” the desired setpoint.

Stage 1 Fan Always ON: selecting this option will run stage 1 fan even during unoccupied times.
