Specifications - Installation and Operating Instructions
Bulletin E-90-TS
The TS Digital Temperature Switch is designed for many
heating and cooling applications. The probe temperature is
displayed on the bright 3-digit, red LED. The user is able to
program 12 different parameters including set point,
hysteresis, cycle time, and ambient probe adjustment using
the front keypad. The unit features error or alarm messaging
and password protection. Select between temperature
display in °F or °C, and 110 VAC, 230 VAC, or 12 VDC
power supplies. The TS includes a thermistor with 5 ft (1.5
m) cable, fitting clips for panel mounting, and instruction
manual.
INSTALLATION
NOTE:
Unit must be mounted away from vibration,
impacts, water and corrosive gases.
• Cut hole in panel 2.80 x 1.14 inches (71 x 29 mm).
