General Overview and Introduction
Phasefale's TC1 is a single stage
(on/off) temperature controller with
defrost capabilities and is simple to
set up and operate. The temperature is
shown on the LED display. If cooling
or heating operations are occurring a
point is displayed at the end of the
temperature display. During defrost,
dF is displayed. The programmed
settings may be viewed by pressing
and holding the button for 2
seconds. A (display only) temperature
alarm is indicated by the flashing of
the temperature display.
The TC1 is a simplified version of the
TACm control which includes
sophisticated alarm facilities in
addition to the control capabilities of
the TC1 detailed here.
1. INSTALLATION
Enclosure Installation
The Enclosure can be mounted in any
position, and is splash proof. Mount
the base and fit two of the mounting
screws in the lid. The lid can then be
hinged out to allow the electrical
connections to be made.
Temperature Sensor (M Probe)
Installation
The temperature sensor is an NTC
thermistor of extreme accuracy
(0.2°C), and it has a non-linear
resistance-temperature characteristic
(see chart below). It is ideally mounted
in a position where refrigerated air is
circulating.
At least 150mm of the sensor cable
needs to be in the refrigerated space
to ensure accurate temperature
sensing.
If the sensor cable is open or short
circuit, the TC1 will display Er to
indicate the fault.
The sensor cable is double insulated
and therefore does not need to be
enclosed in a conduit. There is no
polarity to the sensor connection. It
may be extended up to 100 metres by
joining an extra cable (use double
insulated cable) but the join must be
well insulated and away from any dirt
or moisture.
Dirt or moisture at the join will reduce
the resistance of the probe and result in
a higher temperature reading than
normal.
Electrical Installation
Refer also to the electrical wiring
diagram for connection details. The
Active supply to the unit should be
fused with a maximum rating of 10A.
The control output is rated at 10A
resistive. Motors larger than 1 HP
MUST be switched via a relay or
contactor (available from Phasefale).
If the mdPCB option for heater and
fan outputs is to be fitted, follow the
instructions supplied with it.
TC1 is not supplied with a complog
interface.
Installation Self-Test
Press and together for 5 seconds.
The TC1 automatically cycles its
outputs in the following sequence:
Display Action sec.
CO/CF Control On&Off 10/4
LO/LF nil 4/4
dO/dF nil 4/4
HO/HF Heater On&Off 4/4

2b. A PROGRAMMING
EXAMPLE
A small fruit room needs to be
controlled at 1.0°C. We want a high
alarm at 9.0°C and a low alarm
at -2.0°C to indicate out of range
conditions. Being a small room, we
will set the alarm time to 60 minutes.
As we are energy conscious, we will
use the economy mode of operation.
We want two 45 minute defrosts per
day.
Step 1 Use the auto-setup to load
suitable settings:
•Unlock the TC1 using and
keys. Display reads UL, then...
•Display shows SP eg. 5.0.
•Decrease the setpoint by pressing
until 1.0 is displayed.
•Store the new setpoint with .
•dl (for differential) then Ec
(Economy mode * ) is displayed.
•Press and AU (Automatic
mode *) is displayed.
•Store the automatic setting with
key.
* There are three programming
options in differential dl :
Ec Economy mode - a method to
reduce energy usage whilst using the
internal limit start timer to protect the
compressor.
AU Auto setup - Default settings
(for all the programmable values)
based on your setpoint are loaded into
the TC1's memory.
0.5 to 5.0 Differential Temperature in
° C - The specific temperature
required for the control. (See Cooling
and Heating Operations)
Step 2 The TC1 has stored close
values, but we now "fine tune" the
settings for our application:
•Unlock the TC1: and
•Display UL.
•SP then 1.0 is displayed, press
•dl then EC is displayed, press
.
•AH then 14 is displayed, decrease
the high alarm to 9.0 using
Store the new high alarm setting
with .
•AL then -4.0 is displayed,
increase the low alarm setting to
-2.0 using
•Store the new low setting using
•At then 90 is displayed, decrease
the alarm time delay to 60 using
, then store with .
•nd then 1 is displayed. We want 2
defrosts so press then to
store.
•dd then 30 is displayed, set the
defrost duration to 45 and store
with .
Step 3 Check our Settings
Press for 2 seconds, and our stored
values are automatically displayed.
The TC1 is now ready for operation.
3. COOLING AND
HEATING OPERATIONS
Heating and cooling control is between
the setpoint SP (cut in) and the
setpoint minus the differential dl (cut
out). For example: SP =10oC, dl
=1.0oC: control between 9.0oC and
10°C. Another example: SP = -10oC,
dl =3.0oC: control between -10oC and
-13oC.
The Heating and Cooling options HE
and Co [AA menu] select whether the
C1/C2 output controls heaters or
coolers. In heating mode there is no
limit start timer or defrost function and
programming options which relate to
defrosts will be skipped. If Cooling is
selected, a limit start timer protects
against short cycling the compressor.
The timer will prevent the cooling
output turning on for a period starting
the previous time the cooling output
turned on. Once this period has
elapsed the output is free to turn on as
required. The limit start period is the
units part of the AA (alarm
acknowledge) setting. For example
AA=4,14,24 etc. means a limit start
period of 4 minutes, AA=9,19,29,39
etc. means 9 minutes, AA=10,20,30
etc means 0 minutes or no limit start
delay.
C1/C2 comes on when cooling is
required.
The terminate/range temperature
function tE/rA referred to in
programming is not available in the
TC1 model.
4. ALARM
Where alarm lights, buzzers and
connection to a dialler system is
required, the TACm model should be
used.
The Alarm function has a high
temperature (in °C) setpoint, AH, a
low temperature (in °C), AL, and a
time delay, At. If either setpoint is
exceeded for longer than the time
delay an alarm will occur, indicated
solely by the display flashing. If
cooling mode is selected the low alarm
will occur in 1/4of the time delay At.
An Alarm Memory is shown by the
display flashing but the temperature
has returned to normal limits. In this
situation, an alarm has occurred but
the temperature has since returned to
normal operating limits. It may be
cleared by pressing the button.
5. DEFROST
The defrost duration dd is the time in
minutes in which the refrigeration is
switched off and the heaters are on.
Defrosts are spaced at equal periods
during the day and the number per day
is set by nd. For example, if nd = 2 a
defrost will occur every 12 hours.
A 24 hour clock sets the time of day
for defrosts.
Press to find out when the next
defrost will occur, td is displayed,
followed by the number of hours until
the next defrost. Similarly, pressing
displays Fd followed by the number
of hours since the last defrost
occurred. The decimal place represents
10 minutes, ie 2.4 is 2 hours and 40
minutes.
To initiate a Toggle Defrost, hold the
button for 1 second and either

P:\1doc\pman\cinst\TC156.DOC Page 3 of 4 Q1 2008 Issue 3
dF or Co will be displayed, to indicate
whether the refrigeration is presently
in defrost or cooling mode. Press the
button followed by to initiate a
defrost or press the button followed
by to terminate a defrost.
Further defrost functions can be
accessed via [AA menu]. The Sd
(Show defrost) function alternates the
display between dF and the
temperature during defrosts, whilst Hd
(Hide defrost) causes the display to
show only dF during defrost.
Also accessible [AA menu],St refers
to the Start Time of the first defrost.
Defrosts will then occur at periods
evenly spaced during the day as set by
nd .
The Heater Drain Time dt [AA menu]
sets the period in minutes from the end
of the defrost period dd until the
cooling output is allowed to operate.
The Ft Fan Delay Time sets the
period in minutes from the end of the
drain time when cooling comes on to
the time when the fans are allowed to
operate. The decimal place represents
10 seconds, ie 1.3 is 1 minute 30
seconds.
The dE/dg (Electric/hot Gas defrost)
[AA menu] is not available in the TC1
and the default dE setting should be
used.
6. TEMPERATURE
LOGGING
Press both and buttons together.
Lo (Logging) is displayed. Pressing
will show the highest temperature
in the last hour, continue pressing
and the previous hour's highest is
indicated - up to 99 hours.
PL indicates that a power loss
occurred. If you wish to know how
many hours ago a record was stored,
press and together to show the
hours since the record was made.
Once again, pressing will return
you to normal operation.
Repeat the above sequence but press
and the lowest temperatures will be
shown.
