            UTC-2030 and UTC-2230 Thermostats

            Model No. UTC-2030-(program code #)
            Model No. UTC-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.
            • Three temperature sensor inputs: TS1 for pipe temperature control, TS2 (when enabled) for pipe temperature control at second location on the piping system and TS3 (when enabled) to 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 TS1 and TS2. Alarm level is factory set at dedicated level for each sensor. Feature is enabled at customer request.
            • On-off control with a 1°C (1.8°F) temperature deadband for accurate control of piping systems. This close tolerance control can save thousands of kilowatt-hours of power consumption and is ideal to control electric tracing systems in locations where power is costly.
            • Override input (factory programmable): timed between 1-48 hours or non-timed. This feature forces the output "on" or "off" to suit the application.
            • 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 door of the controller operates as follows:
              • Green: When illuminated, the power supply to the controller is "on" and the pipe temperature at the sensor is above the setpoint. When extinguished, the power supply is "off".
              • Amber: When illuminated, the temperature controller is calling for heat.
              • Red: When illuminated, this indicates that one of the alarms has been triggered. Controller is not calling for heat.
              • Amber and Red (alternating): This indicates that one of the alarms has been triggered. Controller is calling for heat.
            • Non-volatile memory retains all programmed parameters in the event of a power outage.

            Sensor type:

            This temperature controller can be factory programmed to operate with one of two different types of temperature sensor. By default the controller is programmed for 100 ohms Platinum RTD sensor(s). It can also be programmed for 2 252 ohms thermistor(s) on special request. The last two digits of the controller's catalog number indicate the programming code. Control program codes from 01 to 49 are for use with RTDs and codes from 51 to 99 are for thermistors. Ensure that the proper type of temperature sensor is used with the controller. Program codes are listed in tables 5 and 6 (program codes are listed here).
