1. DESCRIPTION
2. APPLICATION
It is a temperature-based controller designed for cooling or heating applications. It is loaded with one
temperature sensor and two outputs of control, including a SPDT contact that can be used for alarm or
defrost purposes. Defrost can be electric or hot gas. The controller offers a built-in buzzer and a digital
input which can be configured for door alarm or power outage alarm, or detection of both events through
the single digital input. Two configurable preset options is available for quick parameter change. Preset
include variables such as temperature setpoint, differential and cooling time (interval between
defrosts). Other salient features include internal buzzer, IP65 frontal, min-max temperature record,
temperature sensor response-time control, tamper-proof function and control functions shutdown.

FOR INSTALLATIONS WHERE A SEALING IS REQUIRED
TO AVOID LIQUID CONTACT, THE CUT FOR THE
CONTROLLER MUST BE OF 70,5X29mm MAXIMUM. THE
SIDE LOCKS MUST BE FIXED SO IT PRESSES THE
RUBBER SEALING AVOIDING INFILTRATION BETWEEN
THE CUT AND THE CONTROLLER.
