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
requirements. Use the 16 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 configuration key
(sold separately) to the back of the unit. Press the button 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, compressor
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 button
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.
