Specifications - Installation and Operating Instructions

Bulletin T-TSW-2

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.

• Press SET to store value.

• 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 turning the con­troller off then on again.

LED INDICATIONS
Out1: Indicates relay 1 On or Off as per parameter H2. If H2=dir, with relay 1 On,

LED lit, if H2=inv, with relay 1 On, LED off. It blinks when SP1 is displayed.
Out2: Indicates relay 2 On or Off as per parameter H3. If H3=dir, with relay 2 On,
LED lit, if H3=inv, with relay 2 On, LED off. It blinks when SP2 is displayed.

Silence the Buzzer

ressing the SET and DOWN keys simultaneously silences the buzzer. The mes-

MAINTENANCE

After final installation of the TSW Series Digital Temperature Switch, no routine
maintenance is required. A periodic check of system calibration is recommended.
The devices are not field repairable and should be returned to the factory if recali­bration or other service is required. After first obtaining a Returned Goods
Authorization (RGA) number, send the material, freight prepaid, to the following
address. Please include a clear description of the problem plus any application
information available.
