Specification and Operating Instructions
KLT11-D Temperature Digital Controller
Description
Installation
NOTE: Unit must be mounted away from vibration, impacts,
water and corrosive gases.
Cut hole in panel
2.80 x 1.14 inches)
Apply silicone (or rubber gasket) around the perimeter of
the hole to prevent leakage.
Insert unit into hole of panel.
Slide removable fitting clips onto unit from the back until
secure to panel.
Wiring diagram is displayed on the top of the unit
NOTE: DO NOT INSTALL PROBE CABLE NEAR POWER
CABLES.
The KLT11 is designed for many heating and cooling
applications. It has an input for temperature probe type PTC
or NTC
The probe temperature is
displayed on the bright 3-digit display. The user is able to
program 16 different parameters including set point,
hysteresis, cycle time and ambient probe adjustment using
the silicone front keypad. The KLKey input allows an easy
programming of the parameters. The unit features error
warning and password protection. Select between red,
green or blue display color, temperature display in ºC or ºF
and 115Vac, 230Vac, 24Vac/dc or 12Vac/dc power supplies.
