Dwyer Instruments TS2 Series User manual

DESCRIPTION
Monitor and control temperature for heating and cooling applica-
tions with the Series TS2 Digital Temperature Switch. The Series
TS2 offers twelve programmable functions to customize the unit to
fit application requirements. Use the 15(5) Amp SPDT relay output
to drive a motor, compressor, or fan. Designed with the OEM in
mind, the TS2 offers the ability to configure multiple units with the
touch of a button.
Programming multiple units is quick and easy. Simply program one
switch with the desired parameter settings and connect the config-
uration key (sold separately) to the back of the unit. Press the but-
ton on the configuration key and download the parameter settings.
Connect the key to the other switches to upload the stored settings
with the push of a button.
The TS2 features set point adjustments, static defrost timing, com-
pressor mean time, hysteresis, and ambient probe adjustment.
Security protection is offered using a password code. The Series
TS2 Digital Temperature Switches are designed to operate with PTC
(1000Ω@ 25°C) probes sold separately.
INSTALLATION
The thermostat must be installed by authorized professionals. It
should be located in a place free of vibrations, impacts, water and
corrosive gases.
A hole measuring 71 x 29 mm must be cut in the panel where the
thermostat is to be fitted (apply silicone to make it leaktight). Then,
the fixing cups must be fitted, sliding them onto the thermostat until
secure. Do not force tightening of the screw if the U-brackets are
used. The connections must be covered with the rear cover for this.
WIRING INSTRUCTIONS
Avoid installing the probe’s cables in proximity with any power
cable. If the length of the probe cables measures more than 100
meters, a recalibration adjustment must be made (parameter P1).
FRONT OPERATION
PUSH BUTTONS
Pushing SET once gives access to the SP. Pushing for 8
seconds gives way to the requested code. After entering
the correct code, all parameters are accessible. This but-
ton alternates between text parameters and their value. It
validates the modified parameters. When pressed with
DOWN, it exits parameter programming.
Pressing this arrow allows the user to go to the next
parameter or increase the value viewed on the display.
When pressed for 8 seconds, it activates or deactivates
defrosting.
Pressing this arrow allows the user to go to the previous
parameter or decreases the value viewed on the display.
When pressed for 8 seconds, it activates or deactivates the
continuous cooling cycle. When pressed simultaneously
with SET, it exits the programming mode.
PROGRAMMING PARAMETERS
Access only to Set Point SP (without code protection):
•Press and release SET. SP text appears on the display.
•Press SET again. The real value is shown on the display.
•Modify the value using the UP and DOWN keys.
•Press SET and DOWN to quit programming, or wait 1 minute for

the TIMEOUT.
Access to all parameters (code protected):
•Press SET for 8 seconds. The access code value 00 is shown on
the display.
•Using the UP and DOWN buttons, set the code (factory-set code
is 00).
•Press SET to enter 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.
•Modify the value with the UP and DOWN keys.
•Press SET to enter it, and exit to text parameter.
•Press SET and DOWN to quit programming, or wait 1 minute for
the TIMEOUT.
SETTING THE KEYBOARD CODE TO ZERO
The keyboard code can be set to zero by holding the SET key and
turning the controller off then on again.
LED INDICATIONS
Out: This indicates that the compressor is connected. It waits the
programmed minimum stop time of the compressor.
Def: This indicates that defrosting is activated.
MESSAGES DISPLAY
In normal operation, the probe temperature will be shown. In case
of alarm or error, the following messages will be shown:
• Er- Memory error.
• -- Short-circuited probe error.
• oo- Open probe error.

MAINTENANCE
CLEANING
Clean the surface of the display controller with a soft, damp cloth.
Never use abrasive detergents, petrol, alcohol or solvents.
REPAIRS
After final installation of the TS Series Digital Temperature Switch, no routine
maintenance is required. A periodic check of system calibration is recom-
mended. 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 pre-
paid, to the following address. Please include a clear
description of the problem plus any application information
available. Dwyer Instruments
