            NGUTC-2030 and NGUTC-2230 Thermostats

            Model No. NGUTC-2030-(program code #)
            Model No. NGUTC-2230-(program code #) with circuit breaker

            UTC-2030 and UTC-2230 Thermostats

            This state-of-the-art electronic thermostat is designed to control one or more heating cables operating between 120 and 240 Vac having a total current draw that does not exceed 30 A. It can be fitted with up to three temperature sensors as required by the application. Because separate temperature sensors are used, they may be installed on the pipe during the initial installation phase while the controller itself may only be installed at a later date.

            Features include:

            • Universal power supply allowing operation at 120 to 240 Vac without wiring modifications (no neutral required).
            • 2-pole, 30 A, 240 Vac circuit breaker that allows operation from 120 to 240 Vac and provides a local means of disconnect (on model 2230 only).
            • Internal ground fault detection circuitry eliminating the need for an external ground fault device. "Alarm only" or "alarm and trip" is activated when ground fault condition is present. It is for NGUTC equipment protection only & does not replace the GFCI designed for electric shock protection. Alarm only or alarm and trip is activated when ground fault condition is present.
            • Internal circuitry for load current monitoring.
            • Three temperature sensor inputs (RTD): RTD1 for pipe temperature control, RTD2 (when enabled) for pipe temperature control at another location on the piping system and RTD3 (when enabled) might be used as a 3rd temperature control or serve as a high temperature limit for plastic piping protection. An alarm is activated when an enabled “open” or “shorted” sensor is detected.
            • Low temperature alarm on both controlling sensors RTD1 and RTD2. Applicable on RTD3 when used as control. Alarm level is factory set at a dedicated level for each sensor. Feature is enabled at customer request.
            • USB port for ease of programming using a USB key with factory program codes.
            • Override input (factory programmable): timed between 1-48 hours or non-timed.
            • On-off control with a 1°C (1.8 °F) temperature differential for accurate control of piping systems. This close tolerance control can save thousands of kilowatt-hours of power consumption and is ideal for controlling electric tracing systems in locations where power is costly.
            • Auto-cycle function (when enabled) momentarily turns heating cable "on" at 24-hour interval to monitor ground fault condition of the load.
            • One three-color LED indicator lamp mounted on the enclosure door and connected to the electronic card operates as follows:
              • Green: When illuminated, the power supply to the electronic thermostat is ‘on’ and the pipe temperature at the sensor is above the setpoint. When extinguished, the power supply is ‘off’.
              • Amber: When illuminated, the electronic thermostat is calling for heat.
              • Red: When illuminated, this indicates that one of the alarms has been triggered. The electronic thermostat is not calling for heat.
              • Amber and Red (alternating): This indicates that one of the alarms has been triggered. The electronic thermostat is calling for heat.
            • Non-volatile memory retains all programmed parameters in the event of a power outage.
            • OLED display module indicating alarms, temperature reading & setting, current reading, serial number & software version.
            • CSA approved (#259595)

            Sensor type:

            This electronic thermostat can be factory programmed to operate only with 100 ohms @ 0 °C (32 °F) Platinum RTD sensor(s). The last two digits of the electronic thermostat’s catalog number indicate the programming code (from 01 to 99). Ensure that the proper type of temperature sensor is used with the electronic thermostat. Program codes are listed in annex F and are identified by a label on the electronic cards. (program codes are listed here).
