KLT11IB Temperature Digital Controller
Description
Installation
The KLT11IB is designed for heating and cooling applications. The
probe temperature is displayed on the bright 3-digit display. The
user is able to program different parameters including set point,
hysteresis, alarms and probe adjustment using the silicone front
keypad. The unit features error or alarm warning, internal buzzer
(optional), configurable digital input and password protection. The
KLKey input allows an easy programming of the parameters. Select
between temperature display in ºC or ºF, display color and 230Vac,
115Vac, 24Vac/dc or 12Vac/dc power supplies.
The model reference is given by: KLT11IBXYZ
Where each sufix can take the following values:
X Display Color R=Red, G=Green, B=Blue
Y Supply Voltage 230=230Vac, 110=115Vac
24=24Vac/dc 12=12Vac/dc
Z Units C=ºC, F=ºF
