Specifications - Installation and Operating Instructions
Bulletin T-TSW-1
The Series TSW Digital Temperature Switch combines the trusted,
reliable TS family of temperature controls and an installation friendly
weatherproof enclosure. By using the same programming parameters
as our Series TS2 and Series TSS2, set up can be quickly completed
using the front keys or by using the TS2-K configuration key. In order to
prevent tampering from unauthorized users, a parameter lock physical
jumper and software passcode security are standard in the unit. The
bright, easy-to-read LED display shows the current output status and
the temperature measurement.
The multiple conduit knockouts on the Series TSW give flexibility to the
installer to determine the best location for the conduit entry. Another
installation friendly feature of the Series TSW is the ability to quickly
jumper the line voltage to the common of the output relay using fast
tabs.
INSTALLATION
NOTICE: The thermostat must be installed by authorized professionals.
It should be located in a place free of vibrators, impacts, and corrosive
gases.
NOTICE: Protective plastic overlay should be peeled off after final installation.

PROGRAMMING PARAMETERS
In order to adjust parameters, jumper must be set in unlocked position.
Locked Unlocked
Figure 2
Access only to Set Points SP (without software code protection):
• Press and release SET. Parameter SP appears on the display.
• Press SET to see the value of the parameter.
• Modify the value using the UP and DOWN keys.
• Press SET Key to save the value.
• Press SET and DOWN to quit programming, or wait 1 minute for the
TIMEOUT.
Access to all parameters (software code protected):
• Press SET for 8 seconds. The access code value 0 is shown on the
display.
• Using the UP and DOWN buttons, set the code (factory-set code is 0).
• Press SET to confirm the code. If it is correct, the first parameter label
will be shown on the display (SP).
• Move to the desired parameter with the UP and DOWN keys.
• Press SET to see the value of the parameter.
• Modify the value with the UP and DOWN keys.
• Press SET to save and exit parameter list.
• Press SET and DOWN to quit programming, or wait 1 minute for the
TIMEOUT.
Resetting the parameter pass code
The parameter code can be set to zero by holding the SET key and
cycling power to the unit.
LED INDICATIONS
This indicates that the output is energized or that the compressor is
connected. It waits for the programmed minimum stop time of the
compressor.
This indicates that defrosting is activated.
Error Messages
In normal operation, the probe temperature will be shown. In case of
alarm or error, the following messages will be shown:
• Er- Memory error.
• -- Shorted-circuited probe error.
• oo- Open probe error.
PARAMETER DESCRIPTIONS
SP = Set Point. Temperature desired to regulate the machine. Can vary
from r1 to r2.
r0 = Differential. Heating: If temperature is ≥ SP then output is OFF. If
temperature is < SP - r0 then output is ON. Cooling: If temperature is ≥
SP + r0 then output is ON. If temperature is < SP then output is OFF.
r1 = Lower Set Point Limit.
r2 = Upper Set Point Limit.
d0 = Heat or Cooling Control. Ht = heating control, Co = cooling con-
trol.
d2 = Defrosting Time Remaining, in minutes. If d2 = 0, defrosting will
not start.
d8 = Interval Between Two Defrostings, in hours.
c0 = Minimum Time for Compressor to be OFF. Minimum time for
compressor to stop until it can start again.
c1 = Continuous Cycle Time. The remaining time for a continuous cold
cycle.
c2 = ON Time of fault cycle, during probe error.
c3 = OFF Time of fault cycle, during probe error.
P0 = Selection of Engineering units between F and C.
P1 = Ambient Probe Calibration. Offsets temperature in degrees to
adjust the ambient probe.
H5 = Access Code to Parameters. Factory-set to 0.
H6 = Selection of Input Probe Type: PTC or NTC.
t0 = Temperature Display Limit. Maximum temperature shown on the
display, although the real temperature can be greater.
OPERATION IN CASE OF ERROR
If the probe or thermostat memory should fail, the compressor will be
connected in accordance to the parameters set in C2 and C3.
MAINTENANCE/REPAIR
Upon final installation of the Series TSW, no routine maintenance is
required. The Series TSW is not field serviceable and should be returned
if repair is needed. Field repair should not be attempted and may void
warranty.
