Custom Controller Installation Instructions
Supplying the Custom
Controller with Power
The CC is powered by 24-volts alternating current and rated 8 VA. Connect the 24
volts to Terminals 15 and 16, located under the Power VAC 8VA label (see
Figure 2).
NOTE! The 24-VAC power connection is isolated. One
transformer can be used to power multiple modules within
the restrictions of an 8-VA consumption.
Wiring the Inputs
The CC has a removable terminal strip that uses screw connections. The inputs
are Terminals 1 through 10, located on the left side of the strip (see Figure 2).
Terminals 13 and 14 under the Analog Outputs label are also used as inputs to
monitor feedback from an electric damper actuator.
Auxiliary Potentiometer
The following procedure should be used to connect an auxiliary potentiometer to
the CC.
Step
Procedure
1
Connect the wiper wire to Terminal 1 under the Aux Pot label.
2
Connect the clockwise wire to Terminal 2 under the Aux Pot
label.
3
Connect the counterclockwise wire to Terminal 4 at the Temp
Sensor Input label.
§
This connection makes it possible to adjust the zone setpoint.
The Novar Controls Futura Temperature Sensor (Model FTS-3A) can be used
with the CC to provide optional setpoint adjustment (potentiometers).
Installation instructions are supplied with the sensor.

Each CC must use a Remote Temperature Sensor (RTS-UVC) for discharge air in
addition to one of the following:
§
§
UVC Wall-Mount Indoor Temperature Sensor (WTS-UVC)
Futura Temperature Sensor (FTS-3 or FTS-3A) with temperature setpoint
adjustment
The temperature sensor input terminals are located under the Temp Sensor Input
label on the terminal strip.
Use the following procedure to connect the temperature sensors.
Step
Procedure
1
Connect the Wall-Mount Temperature Sensor’s plus (+) wire to
Terminal 3.
2
Connect the Remote Temperature Sensor’s red wire to Terminal 5.
3
Connect the black (–) wire from both sensors to Terminal 4.
To wire the other sensors to the CC, refer to their specific installation
instructions.
NOTE! Maximum recommended sensor wire length for
connecting the temperature sensors to the CC is 100 feet,
using 22-gauge wire (Belden 8761, Novar Controls
WIR-1010, or equivalent).
Status Input
Terminals 6, 7, and 8, labeled Status Input, are for digital input connections.
Terminals 6 and 7 are for the fan status and Terminals 7 and 8 are for the dirty
filter status. These are dry contact closure, digital inputs and are connected as
normally open with the fan status closing when the fan is on and the filter status
closing when the filter is dirty.
Override Switch Input
A normally open momentary contact switch and a status light-emitting diode
(LED) can be connected to Terminals 9 and 10 under the Override Switch label.
The override’s effective time period is defined in the software.
The Novar Controls Futura Temperature Sensor provides an override switch and
status LED. Its installation instructions outline the proper connections.

Damper Feedback Sensor
Terminals 13 and 14, under the Analog Outputs label, can be used as an analog
input (0 to 10 VDC) to monitor a feedback signal from an electric damper actuator.
This feedback signal measures actual damper motor feedback between 0 and 10
VDC, linear. Figure 3 provides a wiring diagram of this feedback signal.

Custom Controller Installation Instructions
Damper Analog Output
The analog output terminals are listed under the Analog Outputs label, immediately
to the right of the input connections (see Figure 2). Connect the damper to the CC
at Terminal 11 (analog output D). This is a 0 to 10-VDC, 1 mA maximum
connection. Terminals 13 (output F) and 14 are used as an analog input for a
feedback signal from a damper actuator (see “Wiring the Inputs”). Terminal 12
(output E) is not active.
Relay Outputs
The digital relay output terminals are located at the far right side of the terminal
strip under the Relay Outputs label (see Figure 2). Terminals 21 through 26
(outputs A through F) are the actual output connections. Figure 2 and Table 1
can be used to determine the proper connections. Digital relay output D is not
active because of the analog damper connection.
The digital relay outputs tie in directly to the six relay output status LEDs located
on the case of the CC. The relay output status LEDs match the status of the
relay.
§
§
If the contact is closed, the relay is energized and the LED is on.
If the contact is open, the relay is de-energized and the LED is off.
Terminal 20 is for one side of a 24-volt source to be controlled (switched)
through outputs A through F. The relay outputs are isolated from the other
connections to permit the additional power source. One transformer can be used
to power both the CC and the relay outputs if the transformer has enough
capacity.
Network
Communications
A suitable two-conductor shielded cable (Novar Controls WIR-1010 or
equivalent recommended) should be used to make the communication
connections between the CC and the module communications terminals of the
executive module. On the CC, the connections are Terminals 17, 18, and 19,
located under the Module Network label. The plus (+) and minus (–) connections
must be made correctly.
CAUTION!
6
The Shield connection is not a ground like the other
common grounds on the terminal strip. It is dedicated for
communications only. Do not connect any other grounds
to the Shield connection (Terminal 18).

Custom Controller Installation Instructions
Setting the Module
Address
Every Logic One module must have a unique address for the executive module to
identify it. Addresses are assigned in the software during programming. The
system printout shows the address of the CC being installed.
Set the switches with the correct address from 00 to 63 (see Figure 4) and record
the setting on the module address label. The address switches are located in the
center of the terminal strip (see Figure 2).
NOTE! Address 00 should not be used by the CC if it is operating
on an Executive Controller (EC) or Savvy. The IOM
section of the EC or Savvy uses address 00.

Custom Controller Installation Instructions
Checking Installation
The following items should be checked to verify proper installation.
§
Turn on the power to the CC and the rooftop or air-handling unit and its
control circuitry. If the executive module is operating properly, the CC begins
to control the air-handling equipment in about 3 minutes (after performing a
self-diagnostic check and establishing communications with the executive
module).
§
A schedule status indicator LED is located on the module’s case above the
terminal strip. If the module is communicating properly, this LED should be
flashing according to the schedule mode.
— When the CC is in scheduled off mode, the LED is off and flashes on
briefly when communicating.
— When the CC is in scheduled on mode, the LED is on and flashes off
briefly when communicating.
§
If a timed override switch has been installed and programmed, it can be tested
for proper operation by pressing it during a scheduled off mode. The LED
flashes rapidly until the override period ends.
§
The six relay output status LEDs indicate the status of each active digital output.
Verify that the LEDs are lit when the corresponding digital output is on.
§
Monitor the executive module. If any faults or malfunctions still exist, they
are picked up by the executive module and announced by alarm messages.
The CC’s setpoints can be altered from the executive module’s keypad, and
the status display can be monitored for proper equipment response.
