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
sophisticated alarm facilities
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
(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
sensing.
P:\1doc\pman\cinst\TC156.DOC
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

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.

2. PROGRAMMING
The basic programming steps are:
• "Unlock" the TC1 permanent
memory for programming
• Select the setting to be adjusted.
• Alter the setting to your desired
value.
• Store the changed value.
• Return to normal operation.
a) To unlock the TC1 and alter the
settings, press and
seconds. UL will be displayed to
indicate that the system is unlocked.
b) After the TC1 is unlocked press
until the setting you wish to alter is
displayed. The settings and values are
displayed in the table below:
Sett- De- Display

At 90 Alarm Time Delay
(0~99 minutes)
nd 1 Number of defrosts per
24hr (0~6)
dd 30 Defrost
(1~99minutes)
c) After the setting to be adjusted is
displayed, you
decrease the setting by pressing
until the numerical value required is
displayed.
d) To store the changed value, press
the keypad. The new value is now
stored indefinitely and will remain
during power loss.
e) If no keypad is pressed for 60
seconds the TC1 will once again lock
itself and further alterations will be
disallowed until unlocked again. This
will also occur if the
during the programming operation.
Remember! you must store each
altered value using
