Introduction

The TC-9102 series of microprocessor-based controllers is designed for
the control of Fan Coil Units (FCUs) with heating and cooling, and a
single-speed, 3-speed or var iable- speed fan. T h e contr oll er can regul ate
water valves, one or 2-stage electric heating, or a cooling unit wher e the
compressor has its own short cycle protection.

The comfort temperature set point of the controller may be adjusted via a
TM-9100 Series Room Command Module, and the occupied and
unoccupied control modes of operation temporarily changed. A window
open sensing contact may be connected to switch the controller to the off
mode, and a low temperature limit protection feature is available.

The controller is factory-configured to contr ol with default oper ating
parameters so that no external setup devi ces ar e necessar y. However , a
software package for a PC is available to ver i f y th e cor r ect oper ati on of
the controller and to modify the configuration, if necessary.

Winter and summer compensation may be enabled when th e contr oll er
receives outdoor air temperature data via the communications bus, and
modes of operation may be set by time scheduling programs or control
processes in the supervisory system.

Model Types

The TC-9102 Controller is available in several model types according to
the type of outputs and the range of the integrated or remote set point
input. Refer to Ordering Codes at the end of this bulletin for details.

Controller
Functions

The controller can be connected to a Room Command Module, from
which it receives the room temper atur e, the remote set point and other
override signals. The TM-9180 intelligent Room Command Module
provides these signals via a serial bus connection to the controller. The
other Room Command Modules (TM-9150/9160/9170) provide the
signals as individually connected physical inputs to the controller. In
addition, an NTC temperature sensor is available for mounting within the
FCU.

For installations without a Room Command Module, the controller is
available with an integrated set point adjuster. Alternatively, the remote
set point and fan override controls may be incorporated into a custom
FCU control panel. Refer to the Specifications and Technical Data
section of this bulletin for details of the components required.

Standalone
Mode

The controller operates in standalone mode when it is not connected to a
supervisory system via the communications bus nor to a TM-9180 Room
Command Module. In standalone mode the controller may operate in one
of three control modes:

• COMFORT (occupied): control at comfort set point

• STANDBY (unoccupied): control at a standby level set point

• OFF (not in use): low limit control only

The control modes are set by the window contact and occupancy sensor
inputs, and may be modified by the occupancy button on the Room
Command Module as shown in Table 1.

When connected to a supervisory system via the communications bus or
to a TM-9180 Room Command Module, the controller may operate in
COMFORT, STANDBY or OFF control modes, and additionally in
NIGHT mode:

NIGHT (scheduled unoccupied): control at a night level set point.
The control modes are set by the supervisory system or TM-9180, and are

modified by the occupancy sensor input and occupancy button on the
Room Command Module as shown in Table 2. The window contact input
always switches the controller to OFF control mode, and a MANUAL
mode is available from the supervisory system to inhibit the action of the
occupancy sensor and occupancy button.

Controller Set
Points

The set point in all control modes may be modified from the integrated
set point adjuster or from the remote set point dial/control panel on the
Room Command Module, according to the controller model type. The
controller models with a remote set point of 12-28°C require that a Room
Command Module or an external potentiometer is connected to give the
set point. Controllers with a remote set point of +/-3 K have internal
factory set points of 20°C for heating and 22°C for cooling.

The set point is decreased or increased in the STANDBY control mode
by the factory-set “Standby Bias Heating” and “Standby Bias Cooling”
values to reduce the heating or cooling energy required when the room is
temporarily unoccupied.

When a supervisory system is connected, the set point can be further
decreased or increased in the NI GHT control mode to fur ther r educe
energy requirements during scheduled unoccupied periods such as nights,
weekends and holidays.

In the controller there are two “comfort” set points (Comfort Set Point
Heating and Comfort Set Point Cooling), and the difference between
these two values determines th e zer o ener gy band wher e neit her heati ng
nor cooling is required. The controller calculates two working set points
(WSP Heating and WSP Cooling), which are the sum of the comfort set
point values, the “Remote Set Point” value coming from the integrated
set point adjuster or the Room Command Module, and the “Common Set
Point” value. In the supervisory mode an adjustment may be made to the
working set points either by changing the “Comfort Set Points,” or by
changing the value in the “Common Set Point” parameter of the
controller which enables the supervisory system operator to adjust the
setpoints for heating and cooling at the same time without affecting the
zero energy band. In summary:

Working Set Point (Heating) = Comfort Set Point (Heating) (Supervisory System)

+ Remote Set Point (integrated adjuster or Command Module dial)
+ Common Set Point (Supervisory System)
+ STANDBY or NIGHT Bias Heating (if mode is active)

Working Set Point (Cooling) = Comfort Set Point (Cooling) (Supervisory System)

+ Remote Set Point (integrated adjuster or Command Module dial)
+ Common Set Point (Supervisory System)
+ STANDBY or NIGHT Bias Cooling (if mode is active)

When the room temperature is below the working set point for heating,
the heating output increases according to the proportional band and
integral time parameters set for the heating control loop. When the room
temperature is above the working set point for cooling, the cooling output
increases according to the proportional band and integral time parameters
set for the cooling control loop. Heating and cooling control is illustrated
in figures 8 and 9.

Technical Bulletin—TC-9102 7

Alternate Mode

When pressed for about one second, the occupancy button on the Room
Command Module changes the mode of operation of the controller to the
“Alternate Mode” or back to the nor m al “Cont r ol Mode” as shown i n
Table 2. The “COMFORT ( T)” alternate mode is active onl y f or a per iod
of one hour, after which the controller r evert s to the normal control
mode.

Fan Control

The controllers with on/off fan control switch the fan on when the room
temperature is below the working set point for heating and above the
working set point for cooling, and switch the fan off when the room
temperature has entered th e zer o ener gy band by th e value set f or t he f an
differential. The fan can optionally be set to continue running in the zero
energy band in the COMFORT (occupied) mode, using the software
commissioning tool.

In controllers with 3-speed fan control outputs, the fan stages are
switched in sequence as the room temper at ur e decr eases or incr eases, and
Speed 1 remains on in the zero energy band.

In controllers with a 0 to 10 VDC output for a fan speed controller, the
output increases as the room t emper at ur e f all s below th e wor king set
point for heating or rises above the working set point for cooling, and
maintains a minimum output (set by default at 50%) when the room
temperature has entered the zero ener gy band.

For all controllers, in OFF mode the fan is switched off and the heating
and cooling outputs are set to the fully closed or off level. Fan control
sequences are shown in figures 10, 11 and 12.

3-Speed Fan Override

The speed of a 3-speed fan may be set manually from the Room
Command Module when the controller is in COMFORT (occupied)
mode. In the “AUTO” position the speed is set by the controller
according to the room temperature. In the manual “OFF- 1- 2- 3” positions
the fan runs at the selected speed. T h e f an over r ide i s not acti ve in
STANDBY, NIGHT or OFF modes.

In controller models with 2-stage on/off heating and cooling outputs, all
outputs are switched off when the fan speed is set to “OFF” to protect
electrical heating and cooling devices that require a minimum air flow for
normal operation. This feature can be enabled for other types of outputs,
if required, using the software commissioning tool. Refer to
Commissioning later in this document.

Low Limit Mode

The low limit mode is active when the room temperature falls below the
low limit set point. The fan is switched on at full speed and the heating
output is set to the maximum level until the room temperature rises by the
low limit differential value.

Winter/Summer
Compensation

Setpoint

Compensation

(K)

When the controller is connected to a super visor y system , t he wint er
and/or summer compensation modes may be enabled. The supervisory
system must be programmed to set the outdoor air temperature via the
communications bus on a periodic basis. After a power interruption the
winter and summer compensation modes are temporarily disabled until a
new outdoor air temperature value is received. When the outdoor
temperature falls below the winter set point, the working set point of the
controller will be raised or lowered in accordance with the winter
authority slope. When the outdoor temperature rises above the summer
set point the working set point of the controller will be raised in
accordance with the summer authority slope. The maximum amount of
compensation is limited by the Winter Authority Limit and the Summer
Authority Limit.

The effect of the wint er and summer com pensati on on the cont ro ller set
point is shown below.

Auto-dial
Feature

When the controller is connected to a remo te N2 Bus and super vised by a
Metasys N2 Dialer (NU-NDM101-0) which is linked to a Metasys
network by a telephone line, the following alarm conditions in the
controller will initiate the automatic dial feature:

• Window Open

• Low Limit mode

• High or low alarm limit violation of the room temperature when alarm

limits have been set by the supervisory system.

When any one of these alarm conditions occurs, the N2 Dialer will detect
the alarm and connect the remo te N2 Bus t o th e Metasys net wor k. When
the telephone line connection is established the controller alarm status
will automatically be reset and the controller is then ready to report
further alarm condit ions as t hey occur . R efer to the Technical Bulletin of

the NU-NDM101-0 for further information.

Output Types

0 - 10 VDC

DAT - Duration
Adjust Type

The heating and cooling outputs are one of the following types,
depending on the controller model code:

The output is an analog voltage between 0 and 10 VDC in direct
proportion to the controller output from 0 to 100%.

The DAT output is a triac which is switched on for a duration within the
set heating or cooling valve cycle time in direct proportion to the
controller output from 0 to 100%. To avoid unnecessary switching of the
valve actuator when the output is between 0 and 5% the triac remains off,
and when the output is between 95 and 100% the triac remains on. The
default cycle time is 300 seconds.

PAT - Position
Adjust Type

The PAT output is a pair of triacs which are switched on to open and
close an incrementally driven heating or cooling valve. The duration of
switching is directly proportional to the change in the controller output
and related to the full stroke time of the valve such that a 100% change
will completely open or close the valve. At the 0% or 100% position the
duration of switching is increased to ensure that the valve is completely at
its end position and the appropriate triac is switched on for the full stroke
time every two hours to ensure that the valve remains at its end position.
To prevent unnecessary wear on the actuator, the triac output will only be
switched when the output change exceeds 1% in the same dir ection as t he
previous change or 2% if the direction of change is reversed. T he def ault
full stroke time is 60 seconds.

The output is a pair of triacs which are switched on in sequence as the
controller output increases. The first stage triac is switched as soon as the
output is above 0% and the second stage triac is switched when the output
is equal to the set load rating for the first stage which is defaulted to 50%.
The switching differential is fixed at 5%. When this type of output is used
with 3-speed fan control, the output will be switched off whenever the
fan speed is manually overridden to the “OFF” position on the Room
Control Module. The control diagram is shown below.

Note: A minimum of 25 mm of space is required above and below the

controller for the removal of separable terminals.

16 Technical Bulletin—TC-9102

Wiring

Before connecting or disconnecting any wires, ensure that all power
supplies have been switched off and all wires are potential-free to prevent
equipment damage and avoid electrical shock.

Terminations are made on the terminal blocks, at the top and bottom of
the controller, which accept up to 1. 5mm2 wires. Follow the wiring
diagrams shown in figures 14 to 20.

When the TC-9102 model with separable terminal blocks is being wired,
it is recommended that the removable parts of the blocks be unplugged
before terminating the wires, and that they are not plugged in again until
the wiring has been fully checked.

Separate extra low voltage (safe) wiring fr om power line voltage wir i ng.
A distinctive colour such as white or pink is recommended for low
voltage wiring. Keep all cables as short as possible and tie in position. Do
not run cables close to transformers or high frequency generating
equipment.

The 24 V supply must be stable and not shared with other switched
inductive loads. When multiple loads are connected to one transformer,
wire each load from th e tr ansf or m er separ ately so th at any possi ble
disturbances from one load will have minimal effect on other loads.

Complete and verify all wiring connections before continuing with the
installation procedure.

!

CAUTION: Connections to the on/off or 3-speed fan control

terminals may carry up to 250 VAC. Isolate live and
neutral supply lines (double-pole switch) before
servicing.

!

CAUTION: Connections to the on/off or 3-speed fan control

terminals may carry up to 250 VAC. Isolate live and
neutral supply lines (double-pole switch) before
servicing.

To reach the jumpers and swit ches, open the cont r oll er by gr i pping th e
cover with thumb and finger on both sides above center and pull the
cover off using the lower edge as a hi nge. Replace t he cover by r est ing
the lower edge of the cover against the base and then pressing the cover
firmly to engage all four retaining lugs.

Address
Switches and
Zone Jumpers

If the controller is connected to a communications bus, a network address
must be set. Refer to the project documentation for the address setting for
the controller. Addresses 0 to 63 can be set on the address switches. The
zone jumpers allow addressing up to 255 as follows:

Zone 1 Jumper Zone 2 Jumper Address Switch Network Address
OUT OUT 0 to 63 0 to 63
IN OUT 0 to 63 64 to 127
OUT IN 0 to 63 128 to 191
IN IN 0 to 63 192 to 255

The setting on the Address Switches is in binary format:

Switch Numb e r : 1 2 3 4 5 6
Decimal Equivalent: 1 2 4 8 16 32

Example (Address 43):

Switch Numb e r : 1 2 3 4 5 6
Switch Position: ON ON OFF ON OFF ON
Decimal Equivalent: 43 = 1 + 2 + 0 + 8 + 0 + 32

Jumpers

Remove the
half of the factory setting (gain x 2). (Factor y setting is 2K.)

When the

Figure 21: TC-9102 Controller Jumpers and Switches

When all jumpers and address switches have been set, and all connections
have been made and verified, 24 VAC power may be applied. T he Power
LED should be lit. If the communications bus is active the R/T LED will
flash. If the Power LE D is not lit, check the 24 V supply.

The Configuration Tools for Windows® (WS-EURPRO-0) or T C-9100
Commissioning Tool software (TC-9100-TOOL) running on a PC is
required to verify the operation of the controller and to change
parameters. Refer to the Configuration Tools for Windows Manual or the
TC-9100 Commissioning Tool User’s Guide for further information.
