UL&CE Digital Programmable Thermostat Temperature Controller -40℉-176℉ with 4 Relays Output 4 NTC or PT1000 Probe Inputs Refrigeration Heating Cooling Incubator

Model FTC100-A3C(RTC), format 32 x 74 x 82 mm, is microprocessor based controller, suitable for applications on medium or low temperature ventilated refrigerating units. It has four relay outputs to control compressor, fan, defrost, which can be either electrical or reverse cycle (hot gas). The last one can be used as auxiliary output. 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. The third and fourth probes are used to signal the condenser temperature alarm or to display a temperature. The digital input (free contact) is configurable by parameter. Two RS485 outputs allows the user to connect a ModBUS-RTU compatible monitoring system and use for remote display. The USB port allows the user to connect the “Hot Key” to programme the parameter list. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard.
