Series TSW Single Stage Digital Temperature Switch

Specifications - Installation and Operating Instructions

he Series TSW Digital Temperature Switch combines the trusted, reliable TS

T

amily of temperature controls and an installation friendly weatherproof enclosure.

f

y using the same programming parameters as our Series TS2 and Series TSS2,

B
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.

WIRING INSTRUCTIONS

Wiring diagram is displayed on the inside cover of the unit and in figure 1.

NOTICE: If the length of the probe cables measures more than 100 meters, a
recalibration adjustment must be made (parameter P1).

NOTICE: Avoid installing the probe cables in proximity with any power cables.

PARAMETER DESCRIPTIONS

P = Set Point. Temperature desired to regulate the machine. Can vary from r1 to

S

2.

r

0 = Differential. Heating: If temperature is ≥ SP then output is OFF. If temperature

r

s < SP - r0 then output is ON. Cooling: If temperature is ≥ SP + r0 then output is

i
ON. If temperature is < SP then output is OFF.

r1 = Lower Set Point Limit.
r2 = Upper Set Point Limit.

0=Alarm differential. It is the temperature differential between the alarm On and

A

ff cycle.

O

1=Maximum alarm probe1.

A

aximum alarm ON when probe 1 higher than SP1+A1

M
Maximum alarm OFF when probe 1 lower than SP1+A1-A0.

A3=Minimum alarm probe1.

Minimum alarm ON when probe 1 lower than SP1-A3

inimum alarm OFF when probe 1 higher than SP1-A3+A0.

M

5=Alarm verification time. Time from the alarm event until it trips.

A

6=Alarm probe 1 selection. (See Figure 3).

A

AHL=Maximum and minimum alarm probe 1 enabled.
Ano=No alarms probe 1.
AH=Maximum alarm probe 1 enabled.
AL=Minimum alarm probe 1 enabled.

0 = Heat or Cooling Control. Ht = heating control, Co = cooling control.

d

2 = Defrosting Time Remaining, in minutes. If d2 = 0, defrosting will not start.

d

8 = Interval Between Two Defrostings, in hours.

d
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.

3 = OFF Time of fault cycle, during probe error.

c

0 = Selection of Engineering units between F and C.

P

1 = Ambient Probe Calibration. Offsets temperature in degrees to adjust the

P

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.

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.

• AH1 Maximum temperature alarm, probe 1.

• AL1 Minimum temperature alarm, probe 1.

• -- Shorted-circuited probe error.

• oo- Open probe error.
