Models 2698/2699 — Cold/Hot Temperature Controllers

Features:

• Class 2 Isolation

• Microprocessor control

• UL approved file #: E230832

• Optional external switch output

• Conformal coating for operation in moist environments

• Optional expansion connector to support a remote digital display/user panel

Selco/ECC Model 2698/2699 Cold/Hot Controllers offer highend electronic features to provide extremely sophisticated sensing and control of heating, cooling, and humidity. Typical applications include cooling and heating controls for cooking equipment, freezers, refrigerators, and dehumidifiers.

The electronic controllers feature a number of enhanced control options including two or four-digit push-button display panels and bi-color LED indication. Incorporating microprocessor-based technology, the controllers provide excellent performance accuracy, repeatability, and stability.

For maximum versatility, users can select from power input options of 115 VAC or 230 VAC, with Class 2 Isolation Transformer. Further flexibility is provided via the onboard POT or connector that can optionally be used with input signals such as humidity, pressure, or other.

Model 2699 has all the same features as Model 2698, however, includes up to three outputs and onboard bi-color LED indicator. The additional outputs can be programmed to drive a fan, lights, damper, heater, or compressor.

Both models have been designed for ON/OFF cooling control for temperature between -40°F to +100°F (-40°C to +24°C), or heating control for temperatures between 0°F to 285°F
(-170°C to 140°C). Our library of tested application software helps us respond quickly to your requests for testing samples.
