DST-777S: DIGITAL SINGLE STAGE SETPOINT TEMPERATURE CONTROL WITH SINGLE OUTPUT

DST-777S is a microprocessor-based electronic one stage setpoint temperature control, designed to provide one on/off controls (SPDT relay output) for residential/commercial heating, cooling, air conditioning and refrigeration. The DST-777S is equipped with a Dual Digital display with backlit that provides a constant readout of the sensor temperature and can be used to view the setpoint as well as the other programmed settings. The front buttons allow the user to easily and accurately select the set point temperature, differential and heating/cooling mode of the operation.QuickSet feature allows instant setpoint adjustment without entering programming mode. This reliable and versatile control has a very wide setpoint range, an adjustable differential and time delay that makes it applicable in many different applications. DST-777S has Pulse Width Modulation (PWM) to prevent overshoots and undershoots in systems with large thermal mass such as pools or slabs.

APPLICATIONS:

The DST series can be used for a wide variety of applications:

  • Slab thermostat for radiant floor heating system

  • Tank Heating

  • Boiler control (used as a thermostat)

  • Space and return air temperature control

  • Condenser fan cycling

  • Milk coolers

  • Cooling tower pump control

  • Refrigerated warehouses

  • Chillers

  • Beer and beverage coolers

  • Refrigerated display cases

  • Walk-in and reach-in refrigerators

  • Other applications: research, science, laboratory, education, aquarium, hydroponics, pools and more

FEATURES:

  • Reliable Electronic Accuracy

  • QuickSet feature for quick setting of the setpoint without entering the programming mode

  • Easy-to-Read Digital Display with backlit which displays sensor temperature and functional status. It also allows precise setpoint and differential settings

  • Simple programming of setpoint temperature, differential and cooling/heating modes

  • Wide adjustable setpoint with temperature range from -40F to 240F and differential from 1F to 100F. This enables the user to optimize the system performance for any applications. A tighter differential can be achieved (eg. 1F or 1C) than conventional electromechanical controls

  • Advanced PWM(Pulse Width Modulation) Control to achieve high control accuracy

  • One SPDT relay output

  • LED indicates output relay status, heat/cool mode, C/F scale

  • Anti-Short Cycle Delay to ensure the output relay remains off for up to 20 minutes. This would avoid unnecessary hard start and equipment wear

  • User selectable Celsius or Fahrenheit scales

  • Lockout switch to prevent tempering by unauthorized personnel

  • Remote temperature sensor which can be extended to 500 ft.

  • Sensor Failure Indication

  • Easy installation

  • A universal sensor P-01 is supplied with the control. This solid state temperature sensor probe can be extended up to 500 feet.

  • Increase application options and decrease stocking inventory with power input of either 240VAC or 120VAC on a single model

SPECIFICATIONS:

  • Setpoint Temperature Range: -40 to 240F

  • Differential Adjustment: 1 to 100F

  • Accuracy: 1C / 1F

  • Input: 10K ohm thermistor probe model: P-01 (designed for strap on a pipe or insert into a temperature well)

  • Operating Voltage: 120 or 240 VAC, 50/60Hz

  • Relay: 2 x SPDT, 120VAC, Full Load 10A, 1Hp

  • Dimension: 6.5" X 6.0" X 2.7"
