Description
The KLT11 is designed for many heating and cooling
applications. It has an input for temperature probe type PTC
or NTC (selectable by parameter).
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.
