EXPERT NANO 3CF - three-slot electronic thermoregulation device designed to control refrigeration counters, shop windows and static or ventilated refrigeration units with off cycle or electric defrost.
Panel controller for PEGO cooling
On request
The Expert NANO 3CF is a three-slot electronic thermoregulator designed to control refrigeration counters, display windows and static or ventilated refrigeration units with off-cycle or electric defrost. It is equipped with two analog inputs for NTC or PTC temperature probes, one digital input, three relays for compressor control, fan control and defrost function (the defrost relay can be configured as a light command) and a buzzer. The controller can also be configured for heat application.
A defrost version with real time clock is available.
Application
- Control of refrigeration counters, display cabinets and refrigeration units.
Main features
- Can be configured for hot or cold applications.
- Defrost can be configured for off cycle, heater or cycle inversion and frequency and duration can be set. Termination of defrost can be based on time or temperature.
- Programmed defrost clock (RTC) (on some models).
- Relay to control compressor, evaporator fans and defrost elements (defrost output can be set as a light output).
- Configurable input as evaporator probe or dirty condenser alarm probe.
- Key-operated manual START/STOP defrost.
- Key operated on/off.
- Cooler compartment light ON/OFF switch by key or door switch (if defrost output is configured as cooler compartment light).
- Decimal point temperature display/setting.
- Internal buzzer for acoustic signals.
- Flat front surface for easy cleaning and buttons of sufficient size that can be customised with different colours (on request).
- Highly bright display with enlarged icons and numerals.
- PEGO programming philosophy for instant start-up.
- IP65 frontal protection. Dual mounting option: clips / screws.
- RS485 serial connection with Modbus-RTU or Telenet protocol.
- Voltage, relay capacity and terminal type depending on model.
- External transformer for model 3CF11 (optional).
