DESCRIPTION
Monitor and control temperature for heating and cooling applications with
the Series TS2 Digital Temperature Switch. The Series TS2 offers twelve
programmable functions to customize the unit to fit application require-
ments. Use the 15(5) Amp SPDT relay output to drive a motor, compres-
sor, 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 configuration key
(sold separately) to the back of the unit. Press the button on the configu-
ration 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, compressor
mean time, hysteresis, and ambient probe adjustment. Security protec-
tion 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 ther-
mostat 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 recali-
bration adjustment must be made (parameter P1).
FRONT OPERATION
PUSH BUTTONS
Pushing SET once gives access to the SP. Pushing for 8 sec-
onds gives way to the requested code. After entering the cor-
rect code, all parameters are accessible. This button alternates
between text parameters and their value. It validates the modi-
fied 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 param-
eter 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 dis-
play.
•Using the UP and DOWN buttons, set the code (factory-set code is 00).
