EXPERT NANO 4CK13
4 RELAYS DIGITAL THERMOSTAT
The EXPERT NANO 4CK is a 4 relays electronic thermoregulator designed to control refrigerated counters, display windows and static or ventilated refrigeration units with off-cycle or electrical defrosting in real time (RTC). It is fitted with three analogue inputs for NTC temperature probes, one of which is configurable as a digital input, an additional digital input, four relays for the compressor control, fans, defrosting function and alarm and buzzer. As option the connection to an echo temperature repetition.
Applications
-
Control of refrigerated counters, display windows and refrigeration units.
-
Control of two evaporators with two temperature probes of end defrost.
Main characteristics
- Can be configured for hot, cold or neutral zone applications.
- Can be configured for managing day / night (automatic modification of the setpoint for energy saving) activated by time mode (real time clock) or by means of the digital input.
- Can be configured to manage two evaporators with dual temperature sensor for defrost termination.
- Defrosting can be configured for off-cycle, heating element or cycle inversion and frequency and durationcan be set. End-of-defrosting can be based on time or temperature.
- Clock for programmed defrost (RTC).
- Relay for controlling the compressor, evaporator fans, defrosting resistance and alarm (defrost and alarm outputs can be configured like light output).
- Key operated manual START/STOP defrosting.
- Key operated ON/OFF.
- Cold room light ON/OFF switch with key or by means of door switch (if one output is configured like cold room light).
- Display/adjustment of temperature with decimal point.
- Internal buzzer for acoustic signals.
- Flat front surface for easy cleaning and keys of ample dimension which can be customized with various colours (on request).
- High brightness display with increased icons and figures.
- PEGO programming philosophy guaranteeing immediate start-up.
- IP65 front protection. Two-fold fastening options: clips / screws.
- Extractable terminals.
- RS485 serial connection with Modbus-RTU or Telenet protocol.
- External transformer (optional).
- Temperature repeater (optional).
