Selco Products' New Digital Temperature Controller

Reno, NV - March 1, 2011 - Selco Products Company has introduced the second generation 3699A Electronic Temperature Controller offering a highly flexible temperature control solution in a compact, easy-to-install enclosure (75x33x70 mm). Utilizing the latest electronic technologies, the new controller was developed with fewer components thereby reducing costs. The result is an extremely affordable unit that includes a temperature range to over 2,000°F, high functionality software, timer control for energy savings, multiple power and sensor inputs, multiple output types, and a variety of selectable hardware configurations. Typical applications include temperature control for commercial food equipment, heaters, refrigeration/freezers, and HVAC equipment.

Unlike controllers that are limited to single use applications, the 3699A is a flexible all-in-one controller configurable to many applications by simply setting the software options and selecting the correct hardware configuration. Four different operation modes (ON/OFF, with or without defrost, PID control or timer) can be selected and fine-tuned to meet exact application requirements. Additional flexibility is provided by setting of a number of other variables. These include set-point, differential, actuator restrictions, alarms, and timers. Further versatility is provided with power inputs options of 115/230 VAC, 50/60 Hz or 12-24 VAC/VDC. Output choices include SPST relay rated at 10 or 3Amps or 12-24 VDC for external SSR and buzzer alarm.

The 3699A is designed for cooling and heating control for temperatures between -40°F/-40°C to 2100°F/1100°C depending on sensor input. Other performance characteristics include a four digit LED segment display for easy reading and configuring of thermostat settings. Four push buttons for Mode/Menu, Select/Set, UP and Down allow easy navigation. Programmability for setpoint or automatic shut-off provides reduced energy consumption.

"The 3699A offers one of the most flexible temperature control solutions available on the market," says Eugenio Pedroza, Selco Products Sales/Engineering. "Combined with its wide temperature control range and integral electronics housed in a compact, easy-to-install package, OEMs will find it an excellent solution for many of their engineering designs."
