Specifications - Installation and Operating Instructions

Bulletin T-TS3

The Series TS3 Digital Temperature Switch is the ideal control for

on/off heating or cooling applications. This generation of controls has
field selectable engineering units and temperature probe types in order
to reduce the combination of parts that need to be stocked. A built in real
time clock is used for HACCP logging of temperature alarms caused by
temperatures outside of their set limits or loss of power. For refrigeration
applications, the defrost cycle can be initiated based on time or using the
front panel keys. For programming multiple units, the model TS2-K
configuration key can be used to quickly download parameter settings.

INSTALLATION

NOTE: Unit must be mounted away from vibration, impacts, water and
corrosive gases.

• Cut hold in panel 71 x 29 mm (2.80 x 1.14 in).

• Use the supplied gasket or apply silicone around the perimeter of the
hole to prevent leakage.

• Insert unit into hole from the front side of the panel.

• Slide the mounting bracket securely against the panel from the rear of
the unit.

• Wiring diagram is displayed on the top of the control.

Wiring

Avoid installing the temperature probe cables and the digital input wires
in close proximity of any power cables. If the length of the probe cables
is longer than 100 meters, a recalibration adjustment may be made
using the P1 parameter.
