Product Description

EC-4 Digital Temperature Controller For Freezer,Chiller, Refrigeration System, Condensing Unit

GENERAL DESCRIPTION -DIGITAL CONTROLLER XR02CX

 

 

Model XR02CX, format 32 x 74 x 50 mm, is a digital thermostat with off cycle defrost designed forrefrigeration applications at normal temperature.
It provides a relay output to drive the compressor.
It is also provided with 2 NTC probe input.
The instrument is fully configurable through special parameters that can be easily programmed through the keyboard or the by HOTKEY.

It has 4 relay outputs to control compressor, fan, defrost, which can be either electrical or reverse cycle (hot gas) and light (configurable).

It could be provided with a Real Time Clock which allows programming of up to 6 daily defrost cycles, divided into holidays and workdays. A "Day
and Night" function with two different set points is fitted for energy saving.

It is also provided with up to four NTC or PT1000 probe inputs, the first one for temperature control, the second one, to be located onto the evaporator, to control the defrost termination temperature and to managed the fan. One of the 2 digital inputs can operate as third temperature probe. The fourth probe is used to signal the condenser temperature alarm or to display a temperature.

The RS485 serial output allows to connect the unit to a network line ModBUS-RTU compatible such
as the Dixell monitoring units of X-WEB family. The HOT key receptacle allows to program the controller by means the HOT KEY programming keyboard.

The instrument is fully configurable through special parameters that can be easily programmed
through the keyboard.
 

Features :

1. Integrated intelligent control and applicable to the compressor of one HP.

2. Temperature Display/Temperature Control/Manual, automatic defrost by electric heater

3. Evap. Fan Control/Value Storing/Self Testing
